Physiological acne is a milder form of clinical acne and is very frequent in adult women (18 years of age and older). Acne therapy is usually unnecessary in such cases, and so appropriate cosmetic treatments are sought.
To determine the effectiveness of a Topical cosmetic hydrating skincare treatment for adult acne-prone skin (Normaderm, Vichy, France) against the clinical signs of physiological acne: few inflammatory and retentional lesions, uneven (grainy) skin relief, dilated pores, and occasional and/or local hyperseborrhea.
Within the study, the tested product's keratolytic, antimicrobial, and antiseborrheic properties, and its overall ability to improve the clinical signs of physiological acne present in adult subjects were evaluated through objective and clinical evaluation methods by the investigators and through self-evaluation questionnaires by the subjects themselves. The study group was composed of 50 adult women between 18 and 35 years of age with combination or oily acne-prone skin, who were chosen according to previously defined inclusion criteria. They applied the product tested twice daily on thoroughly cleansed skin for a period of 2 months. The results were evaluated after 30 (±2) and 60 (±2) days.
The number of inflammatory and retentional lesions on the forehead, cheeks, and chin decreased after 60 days of use (an average of 30.7% and 70.7%, respectively). The level of sebum secretion on the forehead decreased by 33.4% and the level of skin scaling decreased by 38.5% after 60 days of use. The moisture content in the horny layer on the forehead, cheeks, and chin increased by an average 39.7%. The decrease in pore size and content after 60 days of use was very noticeable. The subjects evaluated all the studied characteristics of the product tested very positively, with results already showing after 30 days of use.
The results of the study confirm that the product tested is suitable for the cosmetic care of adult acne-prone skin, either as an independent cosmetic hydrating skincare treatment, as a complementary cosmetic part of acne therapy, or as a subsequent cosmetic regimen to sustain the results of the acne therapy for a longer period of time.
