Detailed answer

Exfoliating before applying a lip treatment helps to remove dead skin cells and create a smoother surface for the treatment to penetrate. This aids in better absorption and effectiveness of the lip treatment. However, it is important to choose a gentle exfoliator specifically designed for the lips to avoid causing any irritation or damage. After exfoliating, make sure to follow up with a hydrating lip treatment to moisturize and protect the lips from further dryness or chapping.
