Detailed answer

Lip care products, such as balms or creams, can contain ingredients that help to lighten and even out lip discoloration. Look for products that contain ingredients like vitamin C, kojic acid, licorice extract, or niacinamide, which can help to reduce pigmentation. Additionally, exfoliating the lips regularly using gentle lip scrubs can also be beneficial in removing dead skin cells and improving discoloration. However, it's important to note that severe or persistent lip discoloration may require medical treatment or consultation with a dermatologist.
