Did you know that these ingredients shouldn’t be used together? 1. BP and vitamin c - benzoyl peroxide oxidizes vitamin c making it ineffective (so don’t waste your money and do this!) 2. AHAs/BHAs and retinoids- using these together can damage your skin barrier and cause irritation and redness. Instead, try alternating these products every other night if you want to include both in your regimen. 3. retinoids and BP- the BP can also oxidize and make the retinoid ineffective, thus canceling out the benefits. These products can also be irritating when used together. Try using BP in the morning and a retinoid at night. #skincare #skincaretips #dermatologist #derm #skin #didyouknow #skincareproducts #skincareingredients #education #skineducation #skineducator
