On the effectiveness of glycolic acid
Glycolic acid is often a key ingredient in various skin care products. However, there are many opinions on its actual effectiveness, and today we will discuss it in detail.

The efficacy of glycolic acid is first exfoliation. Its molecules are tiny and can penetrate deep into the surface of the skin, loosen the connections between keratinocytes, and make aging keratin easy to fall off. After exfoliation, the surface of the skin is smoother and the color is uniform, as if it is rejuvenated. Looking at the actual experience, many people feel that the skin feels delicate and dull after using products containing glycolic acid.

Furthermore, glycolic acid can stimulate collagen production. At the bottom of the skin, it can promote the activity of fibroblasts and increase collagen synthesis. For collagen, the support structure of the skin is also used, and the skin is full and elastic, and wrinkles are also reduced. Long-term users often see that fine lines on the face are soothed and skin firmness is improved.

However, the effect of glycolic acid is also restricted by many factors. First, the concentration is essential. When the concentration is low, although it is mild, it is weak in exfoliating and stimulating collagen; although the high concentration is strong, it is easy to cause redness, swelling, tingling and other discomfort if the skin has poor tolerance. When choosing a product, you need to choose the concentration according to your own skin type. Second, the frequency of use is appropriate. Excessive use can cause damage to the skin barrier, moisture loss, and reflexive dryness and sensitivity. Therefore, it is recommended to gradually adjust the frequency according to the skin's adaptation conditions.

In summary, glycolic acid is indeed effective, which can improve the texture of the skin, resist wrinkles and rejuvenate the skin. If you want to reap its good effects, you must use it cautiously, select products according to the skin type and control the frequency, so as to benefit the skin and achieve the ideal skin care environment.
