On the combination of glycolic acid and hydroquinone
The beauty of the skin is related to the face, so the method of skin care is sought by everyone. Glycolic acid and hydroquinone are both agents used in skin care, but whether the two can be used together is crucial.

Glycolic acid belongs to the class of fruit acids, which are mild in nature and can exfoliate, make the skin rejuvenate and radiate. On the surface of the skin, it can loosen the connection between keratinocytes, make the old waste keratin shed, and make the skin delicate and smooth. And it can stimulate the production of collagen, reduce fine lines, and tighten the skin.

Hydroquinone is famous for whitening and can inhibit the activity of tyrosinase. This enzyme is the key to melanin production. If it blocks its effect, melanin production will be inhibited, achieving the effect of whitening light spots.

As for whether the two can be used together, it needs to be carefully investigated. In terms of chemical properties, glycolic acid is acidic, and hydroquinone also has certain chemical properties. The combination of the two may cause a chemical reaction, affecting the efficacy or even harmful to the skin. Studies have shown that in an acidic environment, hydroquinone may stabilize or accelerate its oxidation, which not only reduces the whitening effect, but also oxidizes the product or irritates the skin.

Furthermore, although the effects of the two on the skin are different, they are both irritating to a certain extent. Glycolic acid exfoliates the skin and causes thinning. If hydroquinone is used at this time, it may make the skin more sensitive to its irritation, causing redness, swelling, itching and other discomforts.

In summary, if you want to combine glycolic acid and hydroquinone, you should be cautious. Try it before a small area of skin to see if there are any adverse reactions. And you should consult a professional, such as a dermatologist or skin care expert, according to your own skin condition, to get appropriate methods to protect the effect of skin care and avoid skin damage.
