PSA: That stubborn 45-minute peel took me almost 3 hours to fix
I did a mandelic acid peel last week on a client in her late 20s, and the frosting was way more uneven than I expected. I spent nearly 3 hours buffing and neutralizing areas that kept over-processing, while her normal 45-minute appointment turned into a marathon. Turns out she had been using a retinol product from her dermatologist without telling me, which I didn't catch in her intake form. Anyone else had a reaction like this from undisclosed prescriptions?
