Thank you for your review Rheyn, I'm sorry you didn't enjoy the experience with your 20% Salicylic Acid peel. This would put it in the Strong class because unfortunately Health Canada only allows a maximum of 30% strength in Canadian market. I did review your file and we while we appreciate your three orders this appears to be the only peel from this made in Ontario professional product line that you have tried. Nor have we heard from you requesting assistance prior to this review - We care about our customers very much and are here to help whenever possible.
