The main active ingredient in the extract of Rhodiola is salidroside,which has antioxidant,whitening,and radiation resistant effects;Cosmetics mainly use the dry roots and rhizomes of the Sedum plant,Rhodiola grandiflora.
The role of Rhodiola rosea extract in cosmetics
1.Anti aging
Rhodiola rosea extract stimulates fibroblasts in the dermis,promotes the division of fibroblasts and their synthesis and secretion of collagen,and also secretes collagenase to decompose the original collagen,but the total amount of secretion is greater than the amount of decomposition.Collagen forms collagen fibers outside the cells,and the increase in the content of collagen fibers indicates that Rhodiola has a certain anti-aging effect on the skin.
2.Whitening
Rhodiola rosea extract can reduce the generation of melanin in the skin,improve the pigmentation state of the skin,and achieve skin whitening effects by inhibiting the activity of tyrosinase and reducing its catalytic speed.
3.Sunscreen
Rhodiola rosea extract has a protective effect on cells,and its protective effect is stronger under light conditions.This is because Rhodiola glycoside absorbs light energy and converts it into non-toxic energy for cells,thereby exerting a protective effect on cells.Salidroside can significantly inhibit the increase of inflammatory cytokines caused by ultraviolet radiation,and has a significant protective effect on skin damage caused by ultraviolet radiation.
