It's very popular in the market these years.

The mechanism of retinol and retinol esters:

(1) Remove wrinkles

Retinol and retinol esters as messengers can promote the proliferation of keratinocytes in the basal layer of the epidermis; they can stimulate the synthesis of type I and type II procollagen on fibroblasts. Let the skin be filled with collagen again, filling the areas where wrinkles and sagging have appeared.

(2) Anti-photoaging

Retinol and retinol ester compounds can suppress the activity of the two matrix metalloproteinases MMP1 and MMP9, which are excessively excited by ultraviolet rays, it  can reduce the damage to collagen fibers, prevent photoaging and prevent the appearance of wrinkles and sagging.

(3) Remove acne

It promotes the proliferation of basal keratinocytes and accelerates the shedding of keratinized keratinocytes at the same time which making the skin smoother and firmer.
