AHA BHA Toner + Niacinamide Moisturizer

It may be okay for you, since the niacinamide is diluted in the snail mucin, but I would just be careful of overexfoliation. Maybe alternate when you use them and/or give your skin rest days from acids/exfoliants.

i don’t think there’s a problem with mixing those ingredients together as far as i know... here’s something I found on IG, hope it helps.

hey, here is my two cents. I would try to limit your use of actives to one per routine (ie. one in the morning and one on the evening). Saying that, if you want to layer actives, I would definitely give your products time to settle and absorb into your skin before you apply the next one on. Niacinamide and BHAs work well together but I would stay away from combining AHAs with niacinamide. It does depend on formulation and whilst there may not be a chemical reaction from the actives, the other ingredients (like texture enhancers, emollients and etc) between two formulations may not play nicely together. I hope this helps!

I’m using an AHA (7%) toner 2-3 times a week and niacinamide (10%) serum every day and I have to problem whatsoever. I also used the cosrx aha/bha toner, but that one only has like 0.5% aha/bha, so I dont think you have to worry about it.
