Fat-soluble Vitamin A (Retinol) Powder

Retinol (also known as retinol, A subtype of vitamin A) is an essential nutrient for the human body. It participates in the composition of visual cells and is important for maintaining visual function under dark light. At the same time, retinol can bind to retinol binding protein (RBP) on the skin surface and enter skin cells through RBP receptors to produce retinoic acid. Retinoic acid enters the nucleus, combines with related receptors (RXR, RAR) to form various dimers, and combines with the corresponding retinoic acid response elements under the assistance of activators (such as histone acetyltransferase). By regulating and controlling the activation and expression of messenger RNA in the nucleus, retinoic acid regulates cell division and differentiation and stimulates keratinocyte proliferation. It can promote the metabolism of keratinocytes in the epidermis, reduce the degradation of collagen in the dermis, and stimulate fibroblasts to produce more collagen and hyaluronic acid.
