Made my skin burn

I have some spots on my cheeks from the sun and (gasp) getting older. My very friendly cosmetician at Shoppers recommended that I try this product to lighten these spots. I can't use this, it makes my skin burn uncomfortably, and my cheeks got all red and irritated after the first use. I don't know if I had an allergic reaction or what, but I do not recommend this product.

I had dark spots on my forehead. They actually disappeared. Tried so many spot corrector creams. Neostrata is the only cream that worked for me. Thank you!
