tell me the good and bad things about The ordinary aha30%+ bha2% peeling solution

If you haven't used AHA and BHA before, I suggest that you try a product with a lower percentage first, so you can build tolerance on your skin. The first time you use it, you may have some tingly sensation on your skin. If you feel the tingling doesn't disappear after a couple of minutes, you can wash it off, and try using it again in one week or a bit more. Don't use other exfoliants before/after using this product, and avoid using other heavy actives on the same routine to avoid irritation. After using this peeling, go for a full calming/moisturizing routine. And last but not least, don't forget to patch test this one before applying it on your face.

My recommendation: I don't suggest you to use this product. If this is your first time using AHA and BHA, it has a super high percentage of AHA. Since you have dry skin, I highly recommended ypu to avoid using this products. Anyway, this peeling solution actually has a dupe with the lower percent of AHA. I think it suits you better.

Agree with the other two comments - it is very strong even for my oily resilient skin that's used to chemical exfoliation. Make sure you start slowly and follow the instructions. This product doesn't suit everyone but when it works, it works wonders 👌
