On Glycolic Acid and Eczema
Fuglycolic Acid has become increasingly popular in the field of skin care in recent years. However, there are many opinions on its relationship with eczema, and it is urgent to identify in detail.

Glycolic acid belongs to the group of fruit acids and has unique chemical properties. Its molecules are slender and can enter the stratum corneum of the skin smoothly, loosen the bonds between keratinocytes, cause exfoliation of the stratum corneum, and renew the skin surface. It is often the choice for skin rejuvenation. However, this property is also the beginning of its relationship with eczema.

Eczema is a common skin inflammatory disease, which is characterized by skin itching, erythema, papules, blisters, etc., and even erosive exudate. The causes of eczema are complex, involving genetic, immune, environmental and other factors. When the skin has eczema, its barrier function is damaged and its defense ability is greatly reduced.

Although glycolic acid can have a skin-beautifying effect on normal skin, it may be applied to eczema skin, or there are many risks. The skin covering eczema is already fragile, and the exfoliation effect of glycolic acid may exacerbate skin irritation. Skin is irritated, blood vessels dilate, inflammatory factors chemically, and itching, redness and swelling are even more pronounced. There are clinical observations. Some eczema patients try products containing glycolic acid, and they feel skin tingling, itching suddenly increase in a short time, and the range of skin lesions seems to expand.

Furthermore, glycolic acid can change the acid-base environment of the skin. Normal skin has an inherent acid-base balance, which is essential to resist external stimuli and maintain the homeostasis of skin microorganisms. The acid-base balance of eczema skin is already disordered, and the intervention of glycolic acid may make it worse, disrupt the skin microecology, allow harmful bacteria to breed, and further induce or aggravate inflammatory reactions.

However, there are also views that moderate and accurate use of glycolic acid may have auxiliary healing power for eczema. In some patients with mild eczema, low-concentration glycolic acid preparations, with professional guidance, may help the skin's stratum corneum repair and regulate skin metabolism. However, this statement needs more rigorous clinical studies to support it.

To sum up, the relationship between glycolic acid and eczema is subtle. For eczema patients, use products containing glycolic acid with caution. Under the guidance of a professional doctor, choose according to your own skin condition, and never use it rashly, so as not to aggravate the suffering of eczema. Doctors should also explore the mechanism of action of glycolic acid on eczema, and find a more suitable skin care and treatment path for patients.
