Effects of washing of the face with a mild facial cleanser formulated with sodium laureth carboxylate and alkyl carboxylates on acne in Japanese adult males

Efficacy of the continuous use of a lotion with carbon dioxide on male subjects with mild acne

OBJECTIVE

Acne vulgaris is caused by dyslipidemia, dyskeratosis and/or abnormal bacterial growth. The obstruction of skin pores due to hyperkeratosis of the infundibulum contributes to the formation of comedones. Thus, normalizing keratinization of epidermal cells in skin pores might be useful to improve acne. Recently, it has been found that the transcutaneous application of carbon dioxide (CO₂ ) regulates imbalances of the desquamatory process. In this study, we evaluated the efficacy of a skin lotion containing CO₂ on mild acne.

METHODS

Twenty-four healthy Japanese males (20-29 years old) with mild acne attended this evaluation. The subjects were divided into 2 groups, one group used a skin lotion containing CO₂ and the other group used a skin lotion without CO₂ . Following facial washing, each subject topically applied the skin lotion with or without CO₂ twice a day for 4 weeks. Prior to the start of the evaluation (week 0) and following 2 and 4 weeks of treatment, acne symptoms were assessed by a dermatologist and by instrumental measurements.

RESULTS

Topical application of the skin lotion with CO₂ for 4 weeks significantly improved acne symptoms, which was recognized by the subjects. However, treatment with the skin lotion without CO₂ did not improve acne symptoms. This improvement of acne symptoms by CO₂ was not accompanied by changes in sebum levels, skin surface pH, skin capacitance, or porphyrin levels.

CONCLUSION

The transcutaneous application of a lotion with CO₂ improves acne symptoms by normalizing keratinization without affecting skin surface conditions.

The application of skin care product in acne treatment

Acne is a kind of chronic inflammatory skin disease, which is common in the hair follicle and sebaceous gland of teenagers. It often recurs and affects the quality of life of patients. Acne itself can cause the damage of skin barrier function. On the other hand, common acne treatment methods, such as external drugs, systemic drugs, physical, and chemical treatment, can also lead to the damage of skin barrier function and affect the treatment effect. The application of skin care in the adjuvant treatment of acne has been widely concerned. Due to their high safety, good tolerance, and the effect of improving the damaged skin barrier, medical skin care products are a hot spot in the treatment of cosmetic skin diseases in recent years. It can not only increase the curative effect, reduce the side effects, but also increase the compliance of patients when combined with conventional acne treatment. In this article, skin care products and their application in acne treatment were reviewed.

Meeting the Challenges of Acne Treatment in Asian Patients: A Review of the Role of Dermocosmetics as Adjunctive Therapy

Conventional acne treatment presents several challenges such as intolerable side effects and antibiotic resistance. Dermocosmetic products may be used to reduce these unwanted effects. Dermocosmetics include skin cleansers, topical sebum-controllers, skin antimicrobial/anti-inflammatory agents, moisturizers, sunscreens, and camouflage products. Appropriate use of these products may help augment the benefit of acne treatment, minimize side effects, and reduce the need for topical antibiotics. In Asia, there is currently limited scientific data on the application and recommendations for dermocosmetic use in acne vulgaris (AV). This article reviews the evidence on dermocosmetics for AV and provides practice recommendations as discussed during the 4^th Asia-Pacific Acne Leaders' Summit held in Bangkok, Thailand, on 7 and 8 February 2015. Through a premeeting survey, a series of plenary lectures, a stepwise program of discussion sessions, and Medline article review, the Expert Panel set forth relevant recommendations on the role of dermocosmetics as adjunct for treating AV in Asian patients.

Role of cleansers in the management of acne: Results of an Italian survey in 786 patients

BACKGROUND

Modern therapy of acne is based also on moisturizers, cleansers and sunscreens. However, a few studies have been published on cleansers, and never in Italy.

OBJECTIVE

We decided to carry out an epidemiological study on the knowledge, beliefs and perceptions of acne patients regarding cleansers.

METHODS

The survey has been carried out in Italy in 2013-2014. A group of patients with acne completed a questionnaire which included 10 questions.

RESULTS

One hundred and eighteen dermatologists and 786 evaluable acne patients attended the survey. Approximately 70% of patients use a specific anti-acne cleanser. This cleanser is suggested in 57% of cases by a dermatologist. The patients buy this cleanser at the pharmacy (77% of cases). More than 62% of patients are satisfied about this cleanser. More than 66% of patients use the cleanser twice daily. The length of washing is less than one minute in 48% of patients. More than 66% of patients believe that the cleanser has a therapeutical role.

CONCLUSION

The results of this survey cannot be compared with other studies because of the lack of similar studies about this topic. These results suggest that a sample of Italian acne patients consider cleansers as an important adjuvant treatment in acne.
