On the relationship between glycolic acid and dry skin
The use of glycolic acid has attracted much attention in the field of skin care. However, whether it causes dry skin is a major concern for many users.

Glycolic acid, a fruit acid and the like, has unique properties. It can penetrate deep into the stratum corneum of the skin, loosen the adhesion between it, promote the shedding and renewal of keratinocytes, make the skin surface smooth and delicate, and can increase the permeability of the skin and help the subsequent skin care ingredients absorb.

However, its effects on the skin have advantages and disadvantages. Some people feel dry skin after using products containing glycolic acid. The reason is that glycolic acid accelerates keratin metabolism. If the skin's own moisturizing mechanism is not adjusted in time, water loss will be accelerated. The stratum corneum is like the barrier of the skin. Under the action of glycolic acid, this barrier may be temporarily weak, resulting in a decrease in water retention capacity.

However, not everyone will have dry skin with glycolic acid. If the skin is well adapted, or used properly, with appropriate moisturizing measures, the risk of drying can be reduced. If you start using low-concentration glycolic acid products, gradually increase the concentration and frequency of use, so that the skin can adapt to the process. And daily use of skin care products with strong moisturizing power, such as those rich in hyaluronic acid and ceramide, can replenish the moisture lost by the skin and strengthen the skin barrier.

In summary, glycolic acid may cause dry skin, but it is not inevitable. The key lies in the difference in human tolerance to glycolic acid and the care method when using it. Users should choose carefully and use it reasonably according to their own skin type to avoid the pain of dryness and enjoy the benefits of glycolic acid skin care.
