My dermatologist recommended this exfoliating heel and elbow cream, and truly nothing works better for me for dryness, peeling, and dark elbows. It’s almost 30% glycolic acid and literally revitalizes dry and crusty heels/elbows in one day. It’s pricier than other similar creams, but a small amount goes a long way, and it’s hands-down better than any other brand that I’ve tried. LTKBeauty LTKselfcare
