On the effect of glycolic acid on dry skin

Glycolic acid has gradually become more and more important in the field of skin care. However, there are different opinions on its effect on dry skin. Let's discuss it in detail to make sense.

Glycolic acid belongs to a class of fruit acids with unique chemical properties. Its molecules are small and can penetrate the skin. It loosens the connection of keratin between the stratum corneum, making the old keratin peel off and the skin rejuvenated. However, during this process, the maintenance of skin moisture may be disturbed by it.

Because the stratum corneum is the key to skin hydration. Glycolic acid promotes exfoliation. If it is excessive, the integrity of the stratum corneum is damaged, the barrier function is weakened, and the water loss is intensified, resulting in dry skin. Looking at those who use glycolic acid for skin care, the skin may initially feel refreshing and delicate, but over time, some people feel tight, dry, or even peeling. This may be due to high concentration and frequency of use, the skin is not suitable, and the water loss is difficult to replenish.

However, it is not the case. If used properly, glycolic acid can stimulate the metabolism of the skin, increase the activity of dermal fibroblasts, and synthesize more collagen and hyaluronic acid, which are the keys to skin moisturization. Moderate use of glycolic acid can orderly renew the stratum corneum and increase skin hydration. Those who use low-concentration glycolic acid products for a long time will feel better skin quality, moisturizing and elastic.

Therefore, the effect of glycolic acid on dry skin is not absolute. The key lies in the user's ability to review their own skin type and choose the appropriate concentration and frequency of use. For dry and sensitive skin, it is recommended to start with a low concentration, gradually increase the dosage, and add moisturizing products to protect the skin from losing moisture. For oily and tolerant skin, you can increase the concentration and frequency as appropriate, but not too much. In this way, you can avoid the disadvantages of dry skin caused by glycolic acid, enjoy the benefits of its skin care, and keep the skin moisturized.
