Can I use alcohol A for a long time?
Alcohol A, also known as retinol, is a derivative of vitamin A, including retinol, retinaldehyde, retinoic acid, retinol acetate and retinol palmitate. Retinol can promote the formation of collagen and has great advantages in improving skin photoaging, fine lines, wrinkles and pigmentation.
Retinol is the gold standard of skin care products, but the higher the concentration, the better. Retinol needs to be converted into A acid in cells to play its role, and retinoic acid can stimulate the skin to some extent, such as redness, dryness, burning, peeling and itching. Therefore, when using retinol products, there should be a process of establishing tolerance, which needs to follow the principles of low concentration to high and low frequency to high.
After being digested by the skin, alcohol A enters the germ cells of the skin tissue and is finally converted into acid A, which can accelerate the thinning of the stratum corneum, improve the basic metabolism of the skin, and accelerate the renewal of epidermal germ cells, thus generally making the skin smoother. Alcohol A is very effective in promoting the transformation of collagen, which can act on the dermis, accelerate the formation of collagen and prevent wrinkles. The acne skin on the face is best treated with A-generation hydrocarbon components for some skin inflammatory diseases, such as acne, hair follicle keratosis, psoriasis and so on.
It is suggested that the concentration of alcohol A should be 0.05% → 0.1%→ 0.2%/0.3% → 0.5% → higher.
When I first came into contact with alcohol A products, I need to use them every other night for at least two weeks, and then use them every night if my skin is normal. I used it in the morning and evening after two weeks, and there was no abnormality. It should be noted here that alcohol A is photosensitive, so it must be protected from the sun when used during the day.
