Retinol promotes the proper functioning of epithelial cells. Glycoprotein synthesis requires a certain level of vitamin A. Vitamin A is an important component that our immune system also needs. More than 40 years of research has proven that retinol visibly increases skin firmness, can reduce fine wrinkles, significantly improves uneven skin tone, and results in a smooth and fine skin surface. Retinoids (synthesized equivalents of vitamin A) regulate cell differentiation by promoting the process of proliferation and intercellular communication.
When retinoids enter a cell, they form a bond with nucleic sensors. Thus, sections of the cell's genome are activated or slowed down. The effects of retinol on the epidermis are as follows: Epithelial cells begin to produce more protein and collagen fiber networks, and the existing collagen is broken down more slowly. The result of these two effects is that the skin's collagen content increases, which leads to a reduction in wrinkles. Retinol accelerates the division of the cells of the basal layer, thereby stimulating the renewal process of the upper layer of the skin.
Noticeably smoother and fresher skin. Enhancement of the mitotic activity of keratinocytes. Normalization of keratinization, differentiation and melanogenesis. Activation and stimulation of epidermal lipid synthesis, activation of the components of the extracellular matrix of the dermis. A reduction in the number of atypical cells.
