Clinical Tolerability and Efficacy Establishment of a New Cosmetic Treatment Regimen Intended for Sensitive Skin

Abstract

Sensitive skin has a great impact on the quality of life of subjects. In this research, we evaluated the efficacy and tolerance of a cosmetic treatment for facial skincare, consisting of a cleanser, serum and cream. A clinical-instrumental study was carried out on 30 healthy female participants with sensitive and reactive skin and slight-to-moderate wrinkles using a new cosmetic regimen based on a new technology. Skin moisturization, skin barrier function, erythema, elasticity and firmness, and wrinkle depth (skin profilometry) were evaluated at basal time (T0), and after 14, 28 and 42 days of treatment (T14, T28 and T42). All the evaluated variables showed significant improvement at T42 when compared to T0. Moisturization, erythema, firmness, and elasticity had significant improvement at T14 and the other attributes after T28 (transepidermal water loss, wrinkle depth). A high level of tolerance and satisfaction reported by subjects were achieved. This treatment regimen combining the cleanser, the daily cream, and the nightly serum, showed a statistically significant improvement in all of the parameters evaluated, demonstrating its effectiveness as an anti-aging regimen while improving the sensitive skin condition. This regimen was well tolerated by all the participants.
