Modern skincare strategies for aging skin: The role of biotic complexes and plant extracts

Introduction. Skin aging is a multifactorial process, with oxidative stress playing a particularly crucial role. The formation of reactive oxygen species (ROS) initiates a cascade of reactions leading to collagen degradation and elastin disorganization, thereby contributing to visible signs of aging. A rational skincare approach, incorporating gentle cleansing and hydration combined with active ingredient action, can slow down the aging processes.
Aim. To evaluate the efficacy of a skincare line combining a biotic complex and plant extracts in caring for mature skin.
Materials and methods. 30 women aged 30 to 55 years (mean age of 42.5 years), exhibiting age-related skin changes. During the 21 days they applied gentle cleansing foam, soothing, moisturizing toner, boost-serum and eye skin care cream and during the following 7 days only foam and toner. Every week there were an assessment of epidermal barrier parameters using the Multi Skin Test Center 750/IMATE 6602 diagnostic system (Germany) and in 28th day of the study satisfaction with the topical products was evaluated via the TTSI-10 questionnaire.
Results. At baseline, the average skin hydration level was 41.3 UE, sebum production was 26.1 UE, and elasticity was 39.2 UE. At the 21^st day hydration level increased by 35.6%, and elasticity improved by 21.4%. Sebum level showed minimal change. Moreover, the epidermal barrier parameters showed minimal changes between days 21 and 28. Visually, participants reported filling of fine wrinkles and decrease in pigmentation intensity. During the study, no adverse reactions were reported.
Conclusions. The anti-aging potential of the studied cosmetic products is based on the synergistic action of plant extracts, a biotic complex, and active moisturizing components. The significant improvements observed in epidermal barrier parameters validate the importance of a comprehensive approach to caring for aging skin.
