Can Kojic Acid and Retin A Be Used Together?

The bottom line for this question is a question itself: can you handle it? It all boils down to your skin. How sensitive is your skin? Can your skin handle extreme exfoliation? Although some people practice kojic acid and retin A treatment and tolerated it, there are also some who had suffered from hypersensitivity reactions.

Kojic acid works by exfoliation. Kojic acid increases cellular turnover while irritating skin to slough off dead skin cells, dirt, dull skin, and even scars. If you’re solely using kojic acid, you will notice that there is a distinct peeling in more or less than 4 to 12 weeks of prolonged use. However, some people want to increase cellular turnover by using another chemical reagent such as retin A. The duo can increase cellular turnover and cause skin whitening in as little as 4 weeks.


However, there are some experts who recommend this combo and there are some who discourage it. Nevertheless, it still depends on the nature of your skin. The lighter your skin is, the more susceptible it may be to hypersensitivity reactions.

Whatever method you’re using, if it is kojic acid alone or retin A alone, or both, you still need to follow precautionary measures to reduce the chance of hypersensitivity and irritation. First and foremost, cellular turnover would reduce skin protection against harmful UV rays. This would mean you’d easily get toasted in the sun. It is best to put on sunscreen with an SPF of about 30 – better if it is more than 30. Even though you have sunscreen on your skin, it doesn’t mean you can simmer in the sun all day long. Stay indoors. Avoid using more than 2 skin whitening agents. Report any signs of irritation, itching, and inflammation. Take note: retin A may cause slight inflammation. It is normal. However, an exacerbated reaction may mean otherwise.
