Use with caution but a versatile product that I would recommend
I hadn't used glycolic crystals before but had used strong acids in liquid form from Canada (glycolic, lactic, salicylic). I made a decision to augment a skin cream with the glycolic crystals and trial run it in small amounts. I must add I have used acid products for 20 plus years and am very comfortable using them, and have made my own facial products for over ten years now. I mixed a small amount in to the skin cream base and it blended in very nicely without compromising the composition of the cream too much. Tried it on my face. It feels great. No stress to the skin , 2nd night now. Very very happy. Great product to incorporate in to my products that I put together for my own use. Use with caution, but a great ingredient. I will be buying more, no more buying offshore for me!
