On the Mixing of Glycolic Acid and Lactic Acid
Glycolic Acid and Lactic Acid are both acids and are often used in the field of skin care. However, whether the two can be mixed is the key to everyone's doubts.

First of all, glycolic acid, which is an alpha-hydroxy acid, has a small molecule, can quickly penetrate the stratum corneum of the skin, and has strong exfoliation power. It can promote the renewal of keratinocytes, make the skin rejuvenated, and also help to reduce pigmentation and fine lines, making the skin smooth.

Second of all, lactic acid is also an alpha-hydroxy acid, but its molecule is slightly larger, the exfoliation effect is relatively mild, and it has the function of moisturizing, which can keep the skin's moisture and make the skin moist.

As for whether the two can be mixed, it is necessary to be cautious. If the skin has strong tolerance, mixed use may have a synergistic effect. Glycolic acid exfoliates, making it easier for the skin to absorb the moisturizing ingredients of lactic acid, and jointly promotes the skin's metabolism, making the skin smooth and hydrated.

However, for those with sensitive skin, mixed use should be cautious. The strong exfoliation of glycolic acid may cause the skin barrier to be temporarily weakened, and then used in combination with lactic acid, or increase the risk of skin irritation, causing redness, tingling, itching, etc.

Therefore, if you want to mix glycolic acid and lactic acid, you should first test the skin's tolerance. Take a little mixture and apply it behind the ear or on the inside of the forearm. After a few days, if there is no abnormality, you can gradually try to use it on the face. And the initial frequency of use should be low, observe the skin reaction, and then make adjustments.

In short, mixing glycolic acid and lactic acid may have gains in skin care. Of course, it is necessary to adapt to the skin. Only with caution can you protect the health of the skin and obtain the good effect of skin care.
