I'm trying the 15% for the 1st time, after using the 8%. So far, so good!
I bought the 8% mandelic serum by BION and it is literally the only product that clears my acne completely! It also doesn’t dry my face out and make it all flakey like other products would in the past. At first, it actually made my skin a little oily, but my skin got used to it after a few weeks and it’s absolutely terrific. Definitely going to be a repeat customer for this product!
