Cosmetic camouflage advice improves quality of life.

BACKGROUND: The subjective benefit of attendance at cosmetic clinics has not previously been reported. OBJECTIVES: To assess the effect on perceived quality of life (QoL) of cosmetic camouflage advice. METHODS: In a three-centre study, 135 individuals were invited to complete a dermatology-specific QoL measure, the Dermatology Life Quality Index (DLQI), before and 1 month after their first visit to a cosmetic camouflage clinic. RESULTS: Eighty-two completed DLQI questionnaires were returned before the camouflage clinic appointment, and 56 corresponding questionnaires were returned 1 month after. The mean age of responders was 50 years, and the mean duration of their skin conditions was 15 years. The main conditions seen were pigmentary disorders (29%), scars (22%) and vascular disorders (13%). There was a significant difference in mean DLQI scores before and after the clinic visit (9.1 vs. 5.8, P = 0.0001). CONCLUSIONS: When assessed at 1 month, attendance at a cosmetic camouflage clinic appears to improve QoL significantly.

Topical cosmetics and perioral dermatitis.

BACKGROUND: Perioral dermatitis (PD) is a common dermatological disease whose aetiology and pathogenesis remain speculative. Both cosmetics and topical corticosteroids have been implicated. PATIENTS AND METHODS: 75 patients with PD and 125 randomly selected control patients with negative PD records were included in a questionnaire-based study focusing on cosmetics, their use, and topical corticosteroids. The patients were assessed for atopy by clinical criteria, prick tests and specific IgE against a mixture of aeroallergens (CAP SX 1). RESULTS: There were no significant (p < 0.05) differences in facial skin cleansing between the two groups except for night-time cleansing, which was performed more often in the patient group. The use of skin care products yielded significant differences between the patient and control group in respect to skin care in the morning and the use of day creams. Otherwise, the groups did not differ in their skin care regime (number of skin care products used, type of product, frequency of care). The mean monthly expenditure on cosmetic products did not differ significantly between the two groups. 25.3% of the patients used topical corticosteroids which were initiated in all cases after the onset of the rash. Significantly (p < 0.001) higher values were found in the patient group regarding history of atopic diseases (49.3% vs. 15.2%), prick test reactivity (> or =2 reactive prick tests: 49.3% vs. 8.0%), and specific IgE against aeroallergens (CAP SX1 classes > or =2: 50.7% vs. 15.2%). CONCLUSIONS: The often heard argument that PD results mainly from external factors is no longer tenable. A variable interaction between external (e.g. cosmetics) and intrinsic factors (e.g. atopic constitution) appears to lead to PD, perhaps by subclinical repetitive irritation and final overtaxing of the reparative capacity of the epithelial barrier function.

Cosmetic results of cryosurgery versus surgical excision for primary uncomplicated basal cell carcinomas of the head and neck.

BACKGROUND: The incidence of multiple facial basal cell carcinomas (BCCs) is increasing. OBJECTIVE: Comparison of cosmetic results after cryosurgery and excision for primary BCCs. METHODS: Cosmetic results after cryosurgery and excision (prospective randomized study) of primary BCCs in the head/neck area were assessed by five independent professional observers and by the patients. RESULTS: Ninety-six BCCs were treated either with surgical excision (n = 48) or cryosurgery (n = 48). Clinical professionals evaluated the cosmetic results after surgery as significantly better. The beautician had no preference for either therapy. The patient had a significant preference for excision. Localization and size of the tumor did not modify this general preference for excision. The male dermatologist, however, had a tendency to evaluate results in the cheek, periauricular, and neck area as inferior to those in the rest of the face, regardless of which therapy was given. CONCLUSION: In general, cosmetic results after excision are better than after cryosurgery.

Psychosocial issues and their relevance to the cosmetic surgery patient.

Psychosocial issues permeate the field of cosmetic surgery: 1. The preoperative psychological profile of cosmetic surgery patients is likely to differ from that of people who don't come for surgery. Despite several decades of research, this difference is not well understood. 2. Cosmetic surgery patients often look for more than changes in their physical appearance. If these procedures do not lead to improvements in body satisfaction, self-esteem, or quality of life, then what is their purpose? 3. Patient-surgeon rapport is not simply a nice plus if it happens. Patient satisfaction, reduced legal liability, and improved surgical outcome can all be direct reflections of the surgeon's mastery of relationship-building techniques. 4. Identifying and screening out patients who should not have cosmetic surgery can prevent both patient and surgeon frustration and more extreme adverse outcomes. 5. A wide range of studies document the use of psychological techniques to improve surgical outcome.

Amended final report of the safety assessment of dibutyl adipate as used in cosmetics.

Dibutyl Adipate, the diester of butyl alcohol and adipic acid, functions as a plasticizer, skin-conditioning agent, and solvent in cosmetic formulations. It is reportedly used at a concentration of 5% in nail polish and 8% in suntan gels, creams, and liquids. Dibutyl Adipate is soluble in organic solvents, but practically insoluble in water. Dibutyl Adipate does not absorb radiation in the ultraviolet (UV) region of the spectrum. Dibutyl Adipate is not toxic in acute oral or dermal animal toxicity tests. In a subchronic dermal toxicity study, 1.0 ml/kg day-1 caused a significant reduction in body weight gain in rabbits, but 0.5 ml/kg/day1 was without effect. In a study with dogs, no adverse effects were observed when an emulsion containing 6.25% Dibutyl Adipate was applied to the entire body twice a week for 3 months. Dibutyl Adipate was tested for dermal irritation using rabbits and mice and a none to minimal irritation was observed. Dibutyl Adipate at a concentration of 25% was not a sensitizer in a guinea pig maximization study. Undiluted Dibutyl Adipate was minimally irritating to the eyes of rabbits and 0.1% was nonirritating. A significant increase in fetal gross abnormalities was observed in rats given intraperitoneal injections of Dibutyl Adipate at 1.75 ml/kg on 3 separate days during gestation, but no effect was seen in animals given 1.05 ml/kg. Dibutyl Adipate was not genotoxic in either bacterial or mammalian test systems. Clinical patch tests confirmed the absence of skin irritation found in animal tests. Clinical phototoxicity tests were negative. Dibutyl Adipate at 0.1% was not an ocular irritant in two male volunteers. In a clinical test of comedogenicity, Dibutyl Adipate produced no effect. The Cosmetic Ingredient Review (CIR) Expert Panel recognized that use of Dibutyl Adipate in suntan cosmetic products will result in repeated, frequent exposure in a leave-on product. The available data demonstrate no skin sensitization or cumulative skin irritation, no comedogenicity, and no genotoxicity. Combined with the data demonstrating little acute toxicity, no skin or ocular irritation, and no reproductive or developmental toxicity, these data form an adequate basis for reaching a conclusion that Dibutyl Adipate is safe as a cosmetic ingredient in the practices of use and concentrations as reflected in this safety assessment.

Use less cosmetics--suffer less from fibromyalgia?

BACKGROUND: Widespread muscular pain, tenderness, unrefreshing sleep, and fatigue all constitute the fibromyalgia syndrome (FMS), which is often seen in both general and rheumatology practice, primarily in women. The etiology is unknown. The FMS patient usually looks normal. The cardinal finding is the presence of focal areas of hyperalgesia, that is, tender points. My clinical impression was that FMS patients often complained of dry skin. My hypothesis was that overambitious cleaning, resulting in dry skin, and regular use of cosmetics as moisturizers could contribute to their symptoms. METHODS: A prospective, randomized, controlled trial of 48 women with FMS (some of whom had a rheumatic condition) who were regular users of cosmetics was carried out to investigate if a reduced use of cosmetics would reduce the symptoms. The intervention group received special instructions on skin care, with reinforcement when needed. RESULTS: After 2 years, there was significant improvement in pain (p < 0.02), sleep (p < 0.01), and stiffness (p < 0.02), together with better physical function (p < 0.01) and improved wellbeing (p < 0.01) in the experimental group, as measured by the Fibromyalgia Impact Questionnaire (FIQ). CONCLUSIONS: The results should motivate further studies on the possible adverse effects of cosmetic use in FMS and perhaps other conditions.

Possible relation of Tunisian pemphigus with traditional cosmetics: a multicenter case-control study.

Pemphigus is a severe, autoimmune, blistering disorder with a high incidence among young women in rural Tunisia. The authors investigated explanatory environmental factors. A multicenter case-control study was conducted prospectively from 1992 to 1996 in Tunisia. Sixty-eight incident female cases of pemphigus and 166 controls matched on age, hospital, and geographic area were included. Data collected concerned socioeconomic status, medical history, drug intakes, lifestyle, and environment. Several factors were significantly associated with pemphigus in multivariate logistic regression analyses: traditional cosmetics (odds ratio (OR) = 4.0, 95% confidence interval (CI): 1.1, 14.8); Turkish baths (OR = 3.2, 95% CI: 1.4, 7.3); cutting up raw poultry (OR = 5.1, 95% CI: 1.3, 19.4); contact with ruminants (OR = 2.7, 95% CI: 1.3, 5.8); and wasp, bee, and spider stings (OR = 3.1, 95% CI: 1.5, 6.4). A dose-dependent relation was observed for traditional cosmetics. All risks except insect bites were higher when analysis was restricted to younger women, the demographic group with higher incidence. The strength of the associations, the dose-dependent relation for traditional cosmetics, and the increase of risk estimates for younger women support a causal relation. Traditional cosmetics widely used by Tunisian women could play a major role in excess of cases of pemphigus.

Patch test reactions to cosmetic allergens in 1995-1997 and 2000-2002 in Finland--a multicentre study.

Contact sensitivity to cosmetics is common, but the sensitizing chemicals vary between countries and study periods. The present survey aimed at revealing the recent trends in patch test sensitivity with cosmetic chemicals in Finland. We report a retrospective multicentre survey of patch test reactions focusing on cosmetic-related substances and comparing the test results in 1995-97 with those in 2000-02. The most striking increases in the frequency of the patch test sensitivity were found with balsam of Peru and propolis from 4.0% to 6.2% (P < 0.001) and from 0.5% to 1.4% (P < 0.001), respectively, whereas the most prominent decreases were found with methylchloro/methylisothiazolinone and chlorhexidine diglugonate from 2.4% to 1.3% (P < 0.001) and from 1.2% to 0.5% (P < 0.001), respectively. The level of patch test sensitivity to methyldibromo glutaronitrile increased, although not significantly, from 1.0% to 1.5%. An increasing tendency was also found with hair dye chemicals 4-aminophenol and toluene-2,5-diamine or toluene-2,5-diamine sulfate from 1.3% to 3.8% and from 1.4% to 5.2%, respectively, while such a tendency was not found among permanent wave chemicals. The sensitivity level of fragrance mix remained the same (6% - 7%). We conclude that surveys revealing the state of sensitivity to cosmetic chemicals should be performed periodically in different countries.

Cosmetic intolerance.

A study of cosmetic intolerance has been undertaken in 5202 patients tested for possible contact dermatitis. Each patient has been evaluated by medical history and patch testing. Intolerance to cosmetics involved only 5.9% of the total population tested. If other possible sources of allergens (medication, occupation, hobbies etc) are associated, this figure rises to 11.7%. The origin of the cosmetic intolerance is more often an allergy than irritation. Soaps and shampoos are the most important types of cosmetics responsible for adverse reactions. The principal allergens are the fragrances, preservatives, hair dyes and the patients' own products. In this last category, the specific allergen has not always been detected.

Contact allergy to cosmetics: causative ingredients.

Of 1781 patients with contact dermatitis seen during a period of 6 years (1981-1986), 75 (4.2%) had allergy to cosmetic products. The face was most frequently affected. In many cases, the dermatitis was limited to the eyelids (18.7%) or the face (40.0%). Skin care products (moisturizing and cleansing cream/lotion/milk) accounted for more than half (52.3%), followed by nail cosmetics (8.0%), shaving preparations (8.0%) and deodorants (6.8%). The ingredients most often responsible were fragrances (45.1%), followed by the preservative Kathon CG (11.0%) and the emulsifier oleamidopropyl dimethylamine (9.8%). In 14 patients (18.7%), patch tests with the responsible cosmetic product were negative. In them, the diagnosis was made by use tests and/or repeated open application tests. Compulsory declaration of ingredients on cosmetic product labels in the EEC, analagous to the USA situation, would be of great benefit both to patients and to physicians.

Adverse effects of cosmetics and toiletries reported to the Swedish Medical Products Agency 1989-1994.

In Sweden, a cosmetic control system was introduced in 1989 at the Medical Products Agency (MPA). It consists of a register of importers, manufacturers and their products, and a voluntary adverse reaction reporting system identical to that concerning drugs. Between 1989 and 1994, MPA evaluated 191 reports concerning adverse effects of 253 cosmetics and toiletries. 90% of the reports concerned women and the top-ranking product category was moisturizers, followed by hair care products and nail products. The majority of the adverse effects reported involved only the skin, and 90% were eczematous reactions. 70% of the eczemas were classified as contact allergic, as patch tests were positive to the product as is, and in 1/2 of these products, 1 or more relevant allergens could be identified when tests were made with individual cosmetic ingredients. The most common offending ingredients were fragrances, toluenesulfonamide-formaldehyde resin and preservatives. The number of reports is small in relation to the expected number of cosmetic adverse effects, which can be explained by under-reporting. Efforts are being made to persuade Swedish physicians to report more often.

Cosmetic problems in skin of color.

Practitioners are confronted with a myriad of cutaneous diseases affecting skin of color. Skin of color, which encompasses the pigmented skin of those of African American, Asian and Hispanic descent is susceptible to several unique and cosmetically disfiguring problems. Acne vulgaris, pseudofolliculitis barbae, postinflammatory hyperpigmentation and photoaging are diseases which commonly necessitate visits to the dermatologist and are of major cosmetic concern for those with skin of color. Effective treatments are needed to quickly resolve the inflammatory lesions of acne and pseudofolliculitis. The number of agents available for the treatment of postinflammatory hyperpigmentation is limited, and some agents are minimally effective. In addition to more effective therapeutic agents, development of enhanced camouflaging techniques are also necessary. Finally, sunscreens which provide more complete protection for skin of color are needed to address the issue of both photoaging and hyperpigmentation. We look to the cosmetic industry to develop new products and to improve currently existing products to address the cosmetic concerns of skin of color.

[Cosmetic dermatitis. Its relationship with positive patch test results, clinical features and atopy].

Although cosmetic manufacturing has progressed significantly, we still see a lot of skin problems caused by cosmetics. We patch tested 307 patients who showed signs of cosmetic contact dermatitis on the face from using their own cosmetics. The most common sensitizers were hair dyes, especially paraphenylenediamine (PPDA). Eighty-six of the 307 patients were assessed with patch tests for 23 perfumes, 16 tar dyes, preservatives, bases and 7 other items. Perfumes were frequently identified as allergens such as hidroxycitronellal, which turned out to be the most common sensitizer. The eighty-six patients were divided into 7 groups according to the clinical features and were discussed in terms of the period of onset and their age distribution. The relationship between positive patch test results and atopy is also reported.

Preparation and evaluation of cosmetic patches containing lactic and glycolic acids.

BACKGROUND: Alpha-hydroxy acids such as glycolic acid (GA) and lactic acid (LA), are used in cosmetic patches. The important fact in cosmetic patches is its suitable adhesion and peel properties. AIM: The objective of this study was to prepare LA- and GA-containing cosmetic patches and evaluate in-vitro/in-vivo correlation of adhesion properties. METHODS: Pressure-sensitive adhesives with different concentrations of GA and LA were cast on a polyethylene terephthalate film. The patches were evaluated for peel adhesive strength. On the basis of in vitro adhesion properties the patches were selected for wear performance tests and skin irritation potential. RESULTS: The adhesion properties (adhesion to steel plate and skin) and cohesive strength tests indicated the substantial influence of GA and LA concentrations. Based on in vitro adhesion studies the patches containing 3% (w/w) GA were selected for in vivo studies. In vivo studies show that a formulation containing 3% GA displays good adhesion on the skin, but it leaves little residues on the skin. Skin Irritation studies on healthy human volunteers showed negligible erythema at the site of application after 48 h. CONCLUSION: The noninvasive patch test model was found useful for detecting irritant skin reactions to the cosmetic patch containing GA. Our results demonstrated a strong correlation between the adhesion to steel plate and adhesion to skin. But a weak correlation between the degree of adhesive residue on the skin in in vitro and in vivo tests was observed for the formulation containing 3% (w/w) GA.

Recalls of foods and cosmetics due to microbial contamination reported to the U.S. Food and Drug Administration.

In the U.S., food product recalls serve as an important intervention in stemming the consumption of food products contaminated with infectious disease agents. We summarize the number and nature of foods and cosmetics recalled as a result of microbial contamination reported to the U.S. Food and Drug Administration (FDA) for the period 1 October 1993 through 30 September 1998. During this period, microbial contamination of food and cosmetic products was the leading cause for recalls, accounting for a total of 1,370 recalls (36% of all products recalled). Listeria monocytogenes accounted for the greatest number of food products recalled because of microbial contamination, whereas Pseudomonas aeruginosa was the most common microbe associated with recalls of cosmetic products. Dairy products, followed by seafood and pastry items, were the types of products most often associated with recalls due to microbial contamination. The FDA was the entity most often responsible for detecting microbial contamination of foods and cosmetics (33% of all such recalls), followed by state regulatory agencies (24%), and manufacturers/retailers (21%). Nineteen percent of recalls were associated with at least one reported case of illness. Salmonella was the pathogen most often implicated in reports of illness associated with these recalled products.

Validation of an analytical procedure for the determination of oxidative hair dyes in cosmetic formulations.

A high range and variety of cosmetic formulations that contain oxidative hair dyes and matrix-forming compounds have been industrially developed over recent years and are now available on the international market. Member states of the European Union are responsible for conducting analyses of cosmetic products as deemed necessary by law and European regulation enforcement. Therefore, inspection authorities as well as the cosmetics trade and industry need validated analytical methods for the identification, characterization, and/or quality control of specific active ingredients or formulations with the aim of implementing the European Union Cosmetic Directives (76/768/ECC, 95/17/EC). In this frame, we validated a candidate reference method that enables the identification and quantification of hair dye-forming compounds. This method consists of a separation by RP-HPLC coupled with a DAD after a liquid-liquid extraction procedure for separating matrix components from the dye-forming compounds. The validation of the method includes common criteria such as the repeatability of the analysis and the establishment of figures of merit, as well as statistical evaluations and quality assurance in order to follow the recommendations of the Eurachem guide for analytical measurements.

[Cosmetovigilance: a French pharmacovigilance system for cosmetics developed by the French health products safety agency. A proposal for the future].

Since 1999, the French health products safety agency (Afssaps) has been responsible for the safety of cosmetic products. Attempts are underway to set up a French post-marketing surveillance system for cosmetics and a working group specially in charge of setting this up has been created. The "cosmetovigilance" system has the three following objectives: public health concerns about "at risk" ingredients in cosmetic products: animal derivatives, glycol ethers, aluminium, camphor, etc; notification of adverse reactions: creation of standard reporting forms of adverse reactions; follow-up of laboratory quality controls: emergency and routine controls. The "cosmetovigilance" system is not only restricted to the study of adverse reactions occurring with cosmetic products. It will also address public health issues about ingredients and will rely on laboratory controls. The aim of the "cosmetovigilance" system is to investigate but also to prevent the risk of adverse reactions.

Decorative cosmetics improve the quality of life in patients with disfiguring skin diseases.

Dermatoses may have a significant impact on a patient's quality of life, namely the relationship to others, self-image and self-esteem. We therefore asked whether the application of decorative cosmetics might increase their quality of life. Twenty female patients (16-69 y) with skin diseases affecting the patients' face (acne, n = 8; rosacea, n = 9; chronic discoid lupus erythematodes, n = 2; vitiligo, n = 1) were investigated. The patients were instructed by a cosmetician how to use decorative cosmetics (Unifiance , La Roche-Posay, France) and applied it daily for 2 weeks. The dermatology quality of life questionnaire (DLQI) was performed before the first application and 2 weeks afterwards. The clinical course was documented by standardised photography. Unifiance was well tolerated and no side effects occurred. It completely masked the unwanted coloration and application resulted in a significant amelioration of the appearance. The mean DLQI score dropped significantly from 9.2 to 5.5 (p = 0.0009). Improvement of quality of life reached statistical significance among patients with acne (2.8 versus 7.8, p = 0.0078) and among individuals with a less severe initial impairment of quality of life (2.4 versus 4.2, p = 0.007). Thus, the use of decorative cosmetics in disfiguring skin diseases is an effective, well-tolerated measure increasing the patients' quality of life. We therefore suggest that decorative cosmetics can complement the treatment of disfiguring skin diseases.
