Understanding why your lips have darkened is the first step toward correcting them. While genetics plays a major role, several lifestyle and environmental factors stimulate melanin production in the lips.
Top Causes of Lip Hyperpigmentation
- 1. Genetics and Phototype: Melanin density is naturally higher in Fitzpatrick phototypes III to VI.
- 2. UV Sun Exposure: UV radiation triggers melanocytes to produce melanin as a protective shield.
- 3. Smoking & Heat: Nicotine and cigarette heat cause smoker's melanosis.
- 4. Chronic Lip Biting & Licking: Saliva enzymes and friction cause post-inflammatory darkening.
- 5. Dehydration: Chapped lips lose moisture and reflect light poorly, looking dull and dark.
