On the effect of glycolic acid on keloids
Husband keloids, which are different in shape, are caused by excessive hyperplasia of connective tissue after skin damage, red and hard, or itchy or painful, which is unsightly and disturbs the body and mind. Glycolic acid has been famous for skin care for a long time, but there are different opinions on its effect on keloids. Let's try to discuss it today.

Glycolic acid, a family of fruit acids, has a small molecule that can penetrate the stratum corneum smoothly and reach the deep layer of the skin. First, it can promote the metabolism of keratinocytes, causing old cells to fall off in an orderly manner, and new cells to replace them, so that the surface of the skin is rejuvenated and smooth. At the keloid, the stratum corneum is often disordered, and glycolic acid may be able to adjust it, making the skin texture gradually return to normal shape. Second, glycolic acid can stimulate fibroblasts and increase the synthesis of collagen and elastic fibers. Although keloid connective tissue hyperplasia, its structure may be disordered, glycolic acid may help remodeling, making the scar gradually flattened. Third, it is weakly acidic, which can moderately loosen intercellular adhesions, reduce the hardness of the scar, and soften the texture.

According to empirical evidence, some patients feel that the color of the scar is lightened, the hardness is slightly reduced, and the itching and pain are also relieved. However, there are also ineffective cases, due to individual differences, different skin types, and different causes, sizes, and courses of keloids, so the effect is different. And the use of glycolic acid needs to be based on norms, and the concentration, frequency, and duration should be paid attention to. If the concentration is too high, it is used too frequently, or it causes skin irritation, redness, swelling, burning pain, desquamation, etc., which will harm the skin.

To sum up, glycolic acid may be beneficial to keloids, but it is not a panacea. Those who want to use it should first consult a doctor, review their own condition, weigh the pros and cons, and decide to stop. And the way to remove scars often requires a combination of methods, such as surgery, lasers, drugs, etc., to complement each other, and it is expected to be effective.
