Subjects were randomized to receive the fixed combination applied either every evening or every other evening and a daily application of the standard emollient and the test care or a once daily application of the fixed combination and the standard emollient alone.

Clinical evaluations at Day 0, Day 45 and Day 90 included the count of acne lesions, assessment of clinical improvement and local tolerance. The quantitative lipid profile of the stratum corneum of the forehead was also determined. Moreover, skin quality, subject satisfaction, skin discomfort and sebum composition were in favour of these regimens. In conclusion, the tested skincare combined with a fixed adapalene and benzoyl peroxide combination provides a significant adjunctive efficacy and local tolerance benefit in adult women with mild acne.

Both have antibacterial properties against Propionibacterium acnes. This study assessed its efficacy and tolerance as an adjunctive skincare to a fixed adapalene and benzoyl peroxide combination precio de benzac ac 10 adult women with mild acne.

A prospective, randomized study was conducted in Spain and Poland in compliance with local regulatory and ethical requirements. Three hundred healthy women between 25 and 35 years with mild acne, of any phototype, with no topical acne treatment within the two previous weeks, no oral acne treatment within the four previous weeks for antibiotics or 6 months for isotretinoin and no other face dermatoses were recruited.

All women who provided written consent and met the inclusion criteria were randomized at each study site in a 1 : 1 : 1 way to receive for 90 days:. Table 1 summarizes treatment regimens. Investigators were not aware of the regimens to which subjects were randomized. Products were provided in neutral cardboard boxes with an instruction leaflet on how to apply the products. The primary evaluation endpoint was the mean acne lesion count after 90 days. Clinical evaluations at Day 0, 45 and 90 included the count of papules, pustules, nodules and inflammatory cysts, as well as of open and closed comedones.

Local tolerance was assessed at Day 45 and At Day 90, the investigators and subjects rated the skin care regimens globally. The Mann—Whitney test was used to compare the distribution of lipid variables between groups; the Wilcoxon test was used for the intragroup comparison.

At Day 0, demographic median age 29 years 24—36 in Group A, 30 years 24—36 in groups B and Cclinical and cutaneous lipid characteristics were similar for all three groups. Mean acne lesion count at Day 0 and Day Differences were statistically significant at Day 90 from Day 0 for all treatment groups.

A total of 70 complete skin lipid profiles 23 from Group A, 23 from Group B and 24 from Group C were available for quantitative skin lipid assessment.

At Day 90, the lipid profile had significantly improved for all subjects. Detailed mean results at Day 0 and 90 are provided in Fig. Modifications of lipid compounds at Day 90 compared to Day 0. SQOOHoxidized squalene. Interestingly, the improvement was significantly higher with regimens comprising the test care, not only when the fixed combination was applied daily Group C but also when this combination was applied every other evening Group B. This could be related to the fact that the test care decreases the alterations of barrier that fixed combination induces and help restore microbiote, lipidic film and stratum corneum.

Squalene and waxes are characteristic compounds of sebaceous glands lipids while sterols are components of the epidermal lipids. Moreover, the decreased quantity of waxes and glycerides may indicate a better moisturized and protected skin via a higher filmogen activity while the observed decrease in oxidized squalene suggests a decreased P. Results of this study show that the skin barrier function might have improved after 90 days of daily application of the test care adjunctively to the fixed combination and a standard emollient.

This improvement may be potentially due to the fact that the test care improved the free fatty acid profile while it rebalanced the profile of reserve forms playing a role in the improved skin discomfort. No such improvement was observed with the standard emollient alone. It may enable the use of the adapalene and benzoyl peroxide combination once every other day.
