Vitamin A series

Vitamin A series

 

Vitamin A is an indispensable element to maintain life and a type of micronutrient essential to the human body. Vitamin A has two active subspecies, VA1 (retinol) and VA2 (retinal, retinoic acid), of which retinol is the main one. Retinoic acid is well-known in the pharmaceutical industry, but due to its greater irritation and some other reasons, it stops at drugs. Among retinol and retinal, retinol has attracted most people's attention. At present, retinol and retinol esters are widely used at home and abroad, and they have become more popular in recent years.

 

 

The efficacy of retinol and retinol esters

(1) Anti-wrinkle

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, reduce the damage to collagen fibers, prevent photoaging, and prevent the appearance of wrinkles and sagging.

 

(3) Acne

It promotes the proliferation of basal keratinocytes and accelerates the shedding of keratinized keratinocytes, making the skin smoother and firmer.

 

(4) Whitening

On the one hand, retinol accelerates the shedding of melanin-containing keratinocytes and inhibits the formation of melanin. The two-pronged approach solves the problem of pigmentation in two directions.
