Facial hyperpigmentation means darker patches or spots caused by excess melanin. Common causes include:
  • Post-inflammatory hyperpigmentation (PIH): dark marks after acne, eczema, irritation, waxing, or picking.
  • Melasma: symmetrical brown or gray-brown patches on the cheeks, forehead, upper lip, or chin. Sunlight, visible light, pregnancy, contraceptive pills, and hormones can trigger it.
  • Sun spots: more discrete spots after years of sun exposure.
  • Less commonly, medications or a changing mole/skin lesion.

A safe starting routine

Morning
  1. Gentle cleanser.
  2. Optional: niacinamide 4-5% or azelaic acid 10%.
  3. Broad-spectrum SPF 50 sunscreen every day, reapplied outdoors. A tinted sunscreen containing iron oxides is particularly useful for melasma and darker skin tones because visible light can worsen pigmentation. Photoprotection evidence
Night
  1. Gentle cleanser.
  2. Start one active ingredient, 2-3 nights/week:
    • Adapalene 0.1% if you also have acne, or
    • Azelaic acid for dark marks and sensitive/acne-prone skin.
  3. Moisturizer.
Avoid scrubs, lemon juice, “fairness” creams, unregulated bleaching products, and picking acne. Irritation itself can deepen the pigmentation.

Prescription options

A dermatologist may use hydroquinone 4%, tretinoin, or a triple-combination cream. These work but need supervision because overuse can cause irritation and, rarely, ochronosis. Procedures such as peels or lasers should be selected carefully, especially in deeper skin tones, because they can trigger PIH. A review identifies sunscreen and topical therapy as first-line care. Facial hyperpigmentation review
Expect gradual fading, usually over 8-12 weeks or longer. Treat acne or eczema at the same time, otherwise new marks keep forming.
See a dermatologist promptly if a single spot is new or rapidly changing, has irregular borders/colors, bleeds, itches persistently, or if the pigmentation appeared with a new medicine. Also seek advice before retinoids or hydroquinone if pregnant or breastfeeding.
