What is Retinol? Is long-term use of Retinol good for the skin?

Many sisters will find that retinol is present in many skin care products with whitening and anti-oxidation properties, and some retinol skin care products still need to be kept away from light before use. So what exactly is retinol and what role does it play in skin care products? Let’s take a look.

A alcohol is also known as retinol. It is an active ingredient that can be used in skin care products. Long-term use of retinol can make the face smooth and whiten the spots. So is retinol really that magical? Will long-term use be harmful to the skin?

What is A-alcohol

Retinol is absorbed through the skin and enters the skin tissue cells, and is finally converted into A acid to work: accelerate the shedding of keratin, increase skin metabolism, and speed up the renewal of epidermal cells, thereby revealing smoother skin.

Alanine is particularly effective in promoting collagen production. It can act on the dermis to accelerate the production of collagen and prevent the formation of wrinkles. Acne-prone skin is most suitable for using retinol ingredients to treat some skin inflammatory diseases, such as acne, keratosis pilaris and psoriasis.

Is long-term use of A-alcohol good for the skin?

Long-term use of low concentrations of retinol will not cause any harm if the skin tolerates it. If high concentrations of retinol are used for a long time, it will easily lead to accelerated keratin shedding. If the skin's barrier function is incomplete, it will further damage the skin barrier, making the skin fragile and prone to redness, dryness, and peeling.

1. Long-term use of low concentrations of retinol

It effectively promotes the renewal of keratinocytes and the production of collagen, achieving the effects of removing wrinkles, fading spots, and rejuvenating the skin, effectively preventing skin aging.

2. Long-term use of high concentrations of retinol

The rapid renewal of keratinocytes leads to incomplete skin barrier function, the skin becomes thinner and thinner, moisture is easily lost, the ability to resist ultraviolet rays becomes weaker, the skin becomes more and more sensitive, and redness, dryness, peeling, etc. are prone to occur.
