The assessment of sensitive skin syndrome, characterized by subjective unpleasant sensations, remains a challenge, since there is no international consensus on the best diagnostic tools. This study evaluated the combination of the Burden of Sensitive Skin (BoSS) questionnaire and the current perception threshold as diagnostic tools for sensitive skin syndrome, and the relationship between BoSS and the subjects’ smoking status, phototype and skin type. A total of 100 women completed the BoSS questionnaire, and current perception threshold was measured on the face. The BoSS score was significantly higher in the self-reported sensitive skin group compared with the non-sensitive skin group (25.61 vs 14.05; p < 0.001), and in non-smokers vs smokers (23.00 vs 18.37; p < 0.05). In addition, the current perception threshold values were similar between the sensitive and non-sensitive groups. These results suggest that BoSS is a better diagnostic tool for sensitive skin syndrome than the current perception threshold, and that smokers less frequently have sensitive skin than do non-smokers.
IntroductionAcne vulgaris is a common chronic inflammatory disease of the pilosebaceous unit triggered by Propionibacterium acnes. A bakuchiol, Ginkgo biloba extract, and mannitol (BGM) complex has been developed to provide patients with acne with a specific dermocosmetic to be used adjunctively with conventional treatments.ObjectiveThe aim of these studies was to assess the antibacterial, anti-inflammatory, and antioxidative potential of BGM complex and its individual compounds as well as its impact on sebum composition.MethodsThe antibacterial, anti-inflammatory, and antioxidative potential of BGM complex and its compounds was assessed through in vitro, ex vivo, and clinical studies. The clinical benefit of BGM complex formulated in a cream was assessed in subjects prone to acne through sebum composition analysis and photometric assessments.ResultsResults from the studies showed that the BGM complex has significant antibacterial, anti-inflammatory, and antioxidative properties. At similar concentrations, bakuchiol has up to twice the antioxidative potential than vitamin E. In subjects, BGM complex regulated the sebum composition in acne patients by increasing the level of sapienic and linolenic acid and reducing the level of oleic acid. The reduced number of porphyrins on the skin surface showed that it is also effective against P. acnes.ConclusionBGM complex provides a complete adjunctive care in patients with acne by targeting etiopathogenic factors of acne: dysseborrhea, inflammation, and P. acnes proliferation.
Background Atopic dermatitis (AD) is an inflammatory pruritic chronic dermatosis involving the alarmin thymic stromal lymphopoietin (TSLP), which is directly implicated in AD pruritus. Aims To evaluate the efficacy of Tambourissa trichophylla leaf extract (TTLE) titrated in polyphenols and 18β‐glycyrrhetinic acid (GA) in vitro and in vivo for AD pruritus. Patients/Methods Initially, in vitro assessment of TSLP production in keratinocytes was undertaken. In normal human keratinocytes in vitro, TSLP was induced by polyinosinic:polycytidylic acid (Poly:IC), tumor necrosis factor (TNF)‐α, and interleukin (IL)‐4 and then quantified by ELISA in supernatants. Some cells were pretreated with TTLE and/or GA. Thereafter, an in vivo clinical study was performed including 48 infants and children with mild to severe AD flare‐ups, some of which were treated with topical corticosteroids. A topical spray containing TTLE and GA was applied. After 21 days of topical spray application, pruritus, sleeplessness, the SCORing Atopic Dermatitis (SCORAD) index, the Infant's Dermatitis Quality of Life index (IDQOL), and the Dermatitis Family Impact Questionnaire (DFIQ) were assessed. Results Thymic stromal lymphopoietin secretion was inhibited significantly in an AD environment by TTLE and GA by up to 57.2% and 73.3%, respectively. The use of the topical spray induced a significant reduction in pruritus and sleeplessness scores, as well as the SCORAD, IDQOL, and DFIQ indexes in the total group. Similar results were observed in patient subgroups with or without topical corticosteroid treatment. Conclusions A topical spray containing TTLE and GA, which inhibit TSLP secretion, efficiently decreases AD pruritus and improves the quality of life of AD patients.
Purpose Xerosis and pruritus are common chronic dermatological disorders among dialysis and diabetic patients that are frequently underdiagnosed or neglected, which can impact the quality of life of these patients. This study aimed to evaluate the efficacy and safety of a specific dermo-cosmetic product in the treatment of dry skin and pruritus associated with dialysis and diabetes. Patients and Methods Twenty-nine dialysis patients (mean age 62 years) and 40 diabetic patients (mean age 57 years, 88% type 2) were included in two different single-center open-label uncontrolled clinical trials. All patients presented skin dryness according to the Scaling Roughness Redness and Cracks (SRRC) scale, and pruritus and/or insomnia. They applied the dermo-cosmetic product Medi-Secure Atoderm Xereane (NAOS, Laboratoire Bioderma) once or twice a day. The clinical efficacy (SRRC, pruritus, and insomnia), the skin-related quality of life (Dermatological Life Quality Index, DLQI), and the subjective efficacy were assessed at the inclusion visit and after 28 days of product application, as well as the safety. Results After 28 days of application, the product significantly reduced the SRRC global score of 83% (0.9±0.8 vs 5.1±1.2) and 66% (1.4±1.2 vs 4.2±0.5), pruritus intensity of 76% (1.1±1.3 vs 4.6±2.1) and 78% (0.9±1.7 vs 4.2±2.6), and insomnia intensity of 61% (0.9±1.3 vs 2.4±2.3) and 82% (0.9±1.7 vs 4.8±2.7) in dialysis and diabetic patients, respectively. Furthermore, the product’s application led to an improvement of the skin-related quality of life of 50% (5.4 vs 2.7; p<0.0001) in dialysis patients and 71% (6.6 vs 1.9; p<0.0001) in diabetic patients at D28. In addition, the product was greatly appreciated by all patients for its soothing, comforting, repairing, nourishing, and hydrating effects and was very well tolerated by the entire panels. Conclusion This specific dermo-cosmetic product significantly reduces skin dryness, pruritus, and insomnia in dialysis and diabetic patients, thereby greatly improves their skin-related quality of life. By managing and avoiding bothersome symptoms associated with their disease or treatment, this ecobiological dermo-cosmetic can prevent serious complications that constitute a substantial burden on their daily life.
Background: A moisturizer application during the healing process after a tattoo session is a common practice to help wound healing and to reduce discomfort sensations.This practice was recently recommended by the standard European guidelines on tattoos, with the use of an adapted ointment to keep the site moist. Aims:To assess the efficacy and the tolerability of a specific dermo-cosmetic product (Cicabio Pommade, Laboratoire Bioderma, NAOS, France) in tattoo aftercare.Patients/Methods: Thirty subjects included in this survey applied the product immediately after the tattoo session for 14 days. The objective symptoms (redness, edema, skin repair quality) were assessed by the tattooist and the subjects. The subjective symptoms, discomfort sensations (pain, itching, burning sensations, tingling), soothing, moisturizing, and undesirable effects were assessed by the tattooed individuals.Results: After 14 days of application, redness was absent for 100% and 96% of subjects according to the tattoo artist and the subjects, respectively, and edema had completely disappeared for both assessors. Most of the subjects rated the skin quality repair and the aesthetic outcomes as very good to excellent. Soothing and moisturizing effects were observed as early as the first day. The effects were maintained over 14 days. Discomfort sensations were judged absent to slight in 96%-100% of cases after 7 days. They were assessed as absent to slight in all cases for pain, itching, and tingling, and in 96% for burning sensations after 14 days. The product was very well tolerated by 87% of the subjects. Conclusions:Our survey demonstrates that this dermo-cosmetic product is suitable for tattooed skin aftercare as it reduced skin discomfort as soon as the first day and led to a good skin quality repair while being well tolerated.
