If You Overuse These Beauty Products, It Could Actually Be Hazardous to Your Health

"Retinols come in different formulas, and everywhere on the market you can find a company advertising for this skin care 'favorite.' However, if not advised by a board-certified dermatologist, retinols can be too strong for certain skin types and cause a reaction, such as burning or peeling. It's common for a person to flake or have dry skin when they first start a retinol. For new retinol users, I advise using a 0.5 retinol and applying only once or twice a week. Always consult with a board-certified dermatologist on which retinol may be appropriate for your skin." — Dr. Kim Nichols, Avon consulting dermatologist
