On the advantages and disadvantages of the combination of glycolic acid and hydroquinone
The color of the husband's skin is related to the beauty of the face, so people often seek whitening methods. Glycolic acid and hydroquinone are both commonly used in skin care and whitening, but the combination of the two has advantages and disadvantages, which cannot be ignored.

Glycolic acid is a type of fruit acid and has many effects. It can loosen the connection between keratinocytes, make the old stratum corneum fall off, and renew the surface of the skin, so it can make the skin delicate and smooth. And it can promote the synthesis of collagen in the dermis, enhance skin elasticity, and rejuvenate the skin.

Hydroquinone is mainly to inhibit the activity of tyrosinase, which is related to the production of melanin. If its activity is inhibited, melanin production will be reduced, thus achieving the effect of whitening light spots.

The combination of the two, the advantage is that glycolic acid can promote the renewal of the stratum corneum, so that the skin can better absorb skin care products, and help hydroquinone to better exert its whitening power. At the same time, glycolic acid stimulates collagen synthesis, which is in line with the whitening power of hydroquinone, or can make the skin whiten and more textured.

Combined use also has risks. Glycolic acid can cause the stratum corneum of the skin to thin, increase skin sensitivity, and hydroquinone also has a certain irritation. The use of both may make the skin intolerant, redness, tingling, itching and other discomforts. And if hydroquinone is used improperly, long-term high-concentration application may cause adverse consequences such as exogenous brownish yellow disease.

Therefore, if you want to use glycolic acid and hydroquinone in combination, you must be cautious. Try it on a small scale on the local skin first to see if there are any adverse reactions. And it should be guided by professionals. According to your own skin type and skin problems, you should decide the concentration and frequency of use. Do not use it blindly, so as not to damage the skin and be counterproductive.
