Dr. Mary Alice Mina breaks down the top five tretinoin mistakes she sees her patients make — and admits she's made herself. From the dreaded purge to layering too many actives, she explains why so many people quit this powerhouse ingredient right before it starts working, and exactly how to use it correctly. She covers the difference between purging and irritation, the right amount to apply, how often to use it, why it's not a spot treatment, and which products to avoid pairing it with. Dr. Mina also answers a listener's question about her teeth — and shares her own Invisalign and retainer story. This episode is a must-listen for anyone who has tried tretinoin, given up on it, or is too scared to start.
