If the little fairies want to fight against time and retain their young and delicate beauty now, then retinol - as a skin care ingredient in the anti-aging world, babies must have some understanding~
Retinol: one of the forms of vitamin A, so it is also known as A alcohol, is a fat-soluble alcohol substance. It has the function of regulating the surface and stratum corneum metabolism . It can anti-aging, reduce sebaceous spillover, fade epidermal pigment, and protect epidermal cells from bacteria. It is stable to heat, acid and alkali, and is easily oxidized, and ultraviolet rays will aggravate the oxidation process.
as an anti-aging component, what aspects does it play a role?
1. The first step to anti-aging: Replenish hydration and lock
When retinol acts on the dermis, the content of glycosaminoglycan in the skin will also increase significantly, thereby improving the water-locking ability of the dermis, keeping the skin tender and moisturized, and getting rid of dryness.
2. The second step of anti-aging: whitening + fading acne marks
Retinol can inhibit the production and activity of lysinase and reduce melanin production on the one hand; on the other hand, it can accelerate the metabolism rate of epidermal cells and accelerate melanin desalination. The combination of the two plays a role in whitening and fading acne scar pigmentation.
3. The third step of anti-aging: acne removal
Retinol can regulate the metabolism of keratinocytes and avoid blockage of pores, thereby reducing the occurrence of closed acne.
4. The fourth step against aging: Promote collagen production
Retinol helps to improve the existing elastin form in the skin. It can not only alleviate the loss of collagen, but also promote the production of collagen, thereby smoothing dry lines and making the face smooth.

Most people will have more or less intolerant conditions when using Alcohol for the first time. It takes a long time to establish tolerance, otherwise it will come to your door in minutes if it becomes red and broken.
2. Poor stability: encountering ultraviolet rays will aggravate the oxidation process and lose its original activity, so do not contact sunlight and air. It is recommended to use it at night.
