It works for my Very sensitive skin
This is the most gentle liquid exfoliant I've ever used. I have very sensitive skin and 3xs a week doesn't bother my skin at all!
I Highly recommend it.

Bye bye ingrowns and dark spots
I love this exfoliant, I've bought it 3 times already. I use it on all my hyperpigmentation on my back, underarms, and face. It really helps with my ingrown hairs and reduces the appearance of dark spots. Super effective, I love it!

Great product!
I use this once a week. I apply with my fingertips. (It is liquid, so a little goes a long way) After you wash your face for the night- wait a few minutes then apply this. If you don’t wait it might sting for a few minutes- so wait.. Apply your moisturizer after. My face was so soft the next day after one use. It is now a regular in my skin care routine. I do not use another active like retinol or tea tree serum the day after.. just moisturizer. Would recommend and will buy again.

Good product
This seems to be working really well. I used to use a different brand of BHA and I like this one better.
I do wish they had an eye dropper version, but it’s fine.

Works Perfectly
This has improved my complexion greatly. Wrinkles and fine lines are smaller. My pores have shrunken as well
