When discussing whether kojic acid and glycolic acid can be used together, it is necessary to consider carefully. Kojic acid, with its unique characteristics, is used in many fields; glycolic acid also shows specific effects.

If you want to use both, you should first understand the chemical properties of the two. Kojic acid has certain chemical activity, and glycolic acid is no exception. When the two meet, or cause a chemical reaction, the result of the reaction is unpredictable. There may be an enhancement effect, but there is also a risk of conflict.

From a skin care perspective, kojic acid is often associated with whitening and other effects, while glycolic acid is mostly involved in skin rejuvenation. If the two are used together, it may have different effects on the skin. Or the skin rejuvenation and whitening effect synergistically, but it may also cause skin discomfort due to excessive stimulation, such as redness, tingling and other phenomena.

Furthermore, the skin tolerance of different individuals varies greatly. For some people with good tolerance, the use of both or no major harm; however, for sensitive skin, rashly combined use is very likely to cause allergic and other adverse reactions.

Therefore, before deciding to use kojic acid and glycolic acid together, it is necessary to try it on a small scale and closely observe the skin's reaction. If conditions permit, it is wise to consult a professional for advice. Only by acting with such caution can we achieve the purpose of using both safely and effectively to avoid unnecessary damage to the skin.
