In vivo research on cosmetics with a sunscreen and synergistic antioxidant care

Abstract

The article presents research confirming the synergistic action of cosmetics with sunscreens and antioxidants. The aim of the study was to assess the safety and rationalize the use and dosage of photoprotective cosmetics. Skin tolerance and the effectiveness of cosmetic formulations were confirmed and the key ingredients were selected to minimize the appearance of dermatoses. The level of hydration, elasticity, lubrication, transepidermal water loss and the pH value of skin of volunteers were measured. The conducted experiment confirmed the effectiveness of the tested active substances to improve the biophysical parameters of the skin.
