Skinceuticals / Retinol 0.5% and phloretin cf

You know how we tend to "trust" our doctors & derms for professional expertise...as in they see a lot of patients, so you ASSUME they are knowledgeable about skin types. Well, due to that trust, I accepted my Derm's suggestion to use SkinCeuticals. I paid $275 the 2 suggested items to try out. I "tested" a small amount on my crows feet which resulted in a CHEMICAL BURN. Uh oh, it hurt & clearly my skin is not suited for this product, but I didn't become outraged, I just promptly took it back with the packaging and receipt. However, I was told by Heights Dermatology that I would have to call a 1-800 number to "receive a refund" and that's when it all began...I called, was given a "tracking number" & waited..& waited...& lost track of time. When I called again months later, Skinceuticals said the DR's OFFICE was supposed to give me the refund using the tracking number, so I went back again. However, the Dr's office said it was too late, so I called the 1-800 number again who issued me ANOTHER number & even that did not lead to a refund by Heights Dermatology. I have lived through a complete runaround for $275 even with proof of purchase, 99.999999% of the product left because I couldn't use it, & neither Skinceuticals OR the Derm that represented it's value will stand behind it...so BEWARE!! You will be taking ALL THE RISK if you choose to use these dangerous products.
