Deeper tones (V–VI)
Richly pigmented skin is less likely to burn but far more likely to hold on to a mark. Any inflammation — a spot, a scratch, a product that stings — can leave a dark patch that outlasts the original problem by months.
- Post-inflammatory hyperpigmentation: dark marks left behind after acne, shaving, or irritation
- Melasma, which UV and heat both worsen
- Ingrown hairs and razor bumps in shaved areas
- Keloid or raised scarring after picking or aggressive treatment
