On the Mixing of Glycolic Acid and Kojic Acid
If you want to find out whether glycolic acid and kojic acid can be mixed, you need to examine the properties of the two in detail. Glycolic acid has the function of exfoliating, can make the old exfoliation of the skin surface, make the skin renewed, and can promote the metabolism of the skin, making the face more radiant. Kojic acid is famous for its excellent whitening effect, which can inhibit the activity of tyrosinase, thereby reducing the production of melanin, and achieving the effect of whitening light spots.

However, the combination of the two should not be careless. Glycolic acid has a certain acidity, which can cause the stratum corneum of the skin to thin and increase skin sensitivity. Although kojic acid is beautiful and white, some people use it, or there is a risk of allergies. If the two are mixed rashly, it may greatly increase the irritation to the skin. Those with fragile skin may experience redness, swelling, tingling, itching and other uncomfortable symptoms.

If you want to mix, you should try it on a small area of skin first. Take a small amount of the mixture, apply it to the delicate skin behind the ear or inside the arm, and wait for 24 hours. If there is no abnormality, you can use it cautiously on other parts such as the face. And at the beginning of use, the frequency should be low, depending on the tolerance of the skin, and then make adjustments.

In short, the mixing of glycolic acid and kojic acid may have the potential to increase the effect, but there are also risks. Users should exercise caution and observe the skin's reaction in order to ensure the safety of the skin and achieve the desired results.
