On the Reasons Why Glycolic Acid Causes Dull Skin Tone
There are doubts in the world that glycolic acid can cause dull skin tone, and I will try to discuss it today. Glycolic acid is lively, and in the field of skin care, it is often the choice for skin rejuvenation and skin rejuvenation. However, it is not unreasonable to say that it causes dull skin tone.

Glycolic acid has the power to exfoliate the stratum corneum of the skin. When used for the first time, the stratum corneum of the skin is loosened and shed due to its action. This is the way to promote skin metabolism. However, if used improperly, if the frequency is too high or the concentration is too high, the stratum corneum of

The skin activates the protective mechanism due to stress to resist external evil, and melanocytes are stimulated, resulting in an increase in melanin production. Melanin, the key to skin color, is produced in large quantities and transported to the epidermis, resulting in dull skin tone.

And glycolic acid may cause skin inflammation. During inflammation, a variety of cytokines are released, which can also stimulate melanocyte activity. Inflammation persists, melanin production continues to increase, and skin tone dullness becomes more pronounced.

And individual skin differences of users are also important reasons. Dry skin, already thin stratum corneum, poor tolerance to glycolic acid, after use is more likely to cause stratum corneum damage, inflammation, and then lead to dull skin tone; sensitive skin, its barrier function is weak, glycolic acid stimulation, more likely to induce inflammation and abnormal melanogenesis.

Therefore, those who want to use glycolic acid skin care should carefully observe their own skin condition, abide by the norms of use, control its frequency and concentration, step by step, and supplemented by moisturizing and anti-inflammatory methods, in order to avoid the danger of dull skin tone and obtain the benefits of glycolic acid skin care.
