Hyperpigmentation

Addressing dark spots and uneven tone with depigmenting actives and rigorous sun protection.

Types of Hyperpigmentation

Hyperpigmentation has different causes, and treatment depends on the type:

  • Post-inflammatory hyperpigmentation (PIH): Dark marks from acne, eczema, or injury. Usually fades over 6-12 months but depigmenting agents accelerate.
  • Solar lentigines (sun spots): Age spots from cumulative UV damage. Respond well to depigmenting agents but require strict SPF to prevent new formation.
  • Melasma: Symmetric brown patches on the face, often triggered by hormones, genetics, and UV exposure. More stubborn; requires consistent treatment.

Regardless of type, SPF is the most critical factor. Without it, treatment results fade and new spots form.

Depigmenting Ingredients

Vitamin C (L-Ascorbic Acid)

Antioxidant that inhibits tyrosinase (the enzyme that makes melanin) and brightens. Use 10-20% concentration. It's unstable, so look for stable derivatives or airless packaging. Brightening results visible in 4-8 weeks.

Kojic Acid

Natural depigmenting agent from fungi. Mild but effective at 2-4%. Well-tolerated by sensitive skin.

Arbutin

Hydroquinone precursor that converts to hydroquinone on skin. Effective and gentler than prescription hydroquinone. Use 2-4%.

Niacinamide

At 4-5%, niacinamide reduces redness and melanin production. It's gentle and plays well with other ingredients.

The 3-Month Hyperpigmentation Protocol

Month 1-2: Vitamin C (10-15% AM) + Niacinamide toner (4-5% AM/PM) + SPF 50+ religiously

Month 2-3: Rotate to arbutin or kojic acid serum at night if vitamin C irritates, or combine with vitamin C

Ongoing: SPF 50+ daily, non-negotiable. One missed day of sun exposure negates 2 weeks of treatment.

Critical SPF Rules

  • SPF 50+: SPF 30 is insufficient for hyperpigmentation. Use SPF 50+.
  • Daily, without exception: Weekends, cloudy days, indoors (windows block some but not all UV). Every single day.
  • Reapply every 2 hours if outdoors
  • Use enough: Most people use 25% of the amount needed. Use a full finger's length for the face.

Realistic Expectations

Topical depigmenting agents can fade hyperpigmentation by 30-50% over 3-6 months. Complete resolution takes longer, and some stubborn spots require professional treatments like lasers or chemical peels.

The best approach: consistent topical treatment + professional treatment if needed + lifetime SPF maintenance to prevent recurrence.
