The Body Glow Protocol: Glycolic Acid for Dark Armpits, Strawberry Skin & Ingrown Hairs

If you've been using glycolic acid every day on your armpits and wondering why they're getting darker instead of lighter, you're not alone. If you're battling keratosis pilaris on your arms, ingrown hairs on your legs, or rough elbows that won't budge, the problem isn't the ingredient—it's how you're using it. Glycolic acid is one of the most powerful exfoliating acids available, but delicate body skin doesn't respond the way your face does. Overuse leads to irritation, rebound darkening, and zero results. This guide gives you the exact protocols I share in my videos: which strength to use where, how often to apply it without damaging your skin barrier, and the pairing ingredients that amplify glow while protecting against inflammation. You'll learn the spray-bottle hack for back acne you can't reach, the cotton-pad technique for dark elbows, the one-to-two-times-per-week rule that prevents armpit darkening, and how to layer glycolic acid with urea, cica, and tranexamic acid to smooth bumpy skin and brighten hyperpigmentation faster.

It's the same routine I walk through in my videos.
