Can you use kojic acid and retinol at the same time?

Hello and thank you for your question. The fewer products you use, the less chance there is of irritation. It can be difficult to combine bleaching products with other skin care treatments without causing irritation. There are a few products that can enhance a bleaching cream’s performance. These can include vitamin C products, tretinoin, a separate alpha hydroxy acid product, and special cleansers or toners to prep the skin. With the exception of the prepping products, it is wise to alternate the use of the two products rather than applying both at the same time. This will minimize the risk of irritation or adverse reactions. You can use Kojic acid during the day with rigorous use of daily SPF, reapplying every two hours, and your retinol for nighttime. Best of luck.

Hi there,Yes you can... however this may cause irritation.  It really is whatever you can tolerate....    Sometimes it is best to use The Kojic in the am and the Tretinoin in the pm.Lots of sunscreen!   Best of luck....
