What supplements have evidence for reducing hyperpigmentation?

Glutathione, vitamin C, Pycnogenol, and grape seed extract have clinical evidence for reducing melanin production or improving hyperpigmentation. Glutathione shifts melanin synthesis toward lighter pheomelanin. Tranexamic acid (available as both oral and topical) has strong evidence but is typically considered a medication rather than a supplement.

Can supplements alone eliminate dark spots and melasma?

Supplements alone are unlikely to fully resolve established hyperpigmentation or melasma. Strict sun protection is essential, as UV exposure triggers melanin production. Topical treatments (hydroquinone, azelaic acid, vitamin C, retinoids) remain first-line therapies. Oral supplements may provide modest supportive benefit, particularly when combined with topical treatments.

When should someone with hyperpigmentation see a dermatologist?

See a dermatologist if hyperpigmentation is widespread, rapidly changing, appears in unusual patterns, or does not respond to OTC treatments after 3 months. Melasma requires a specific treatment approach. Some pigmentary changes can indicate underlying endocrine disorders. A dermatologist can distinguish between different causes and provide targeted treatment.

Prevalence: Melasma affects 15-50% of pregnant women; PIH common in darker skin tones (Fitzpatrick IV-VI)

About

Excess melanin deposition in the epidermis or dermis, resulting in darkened patches. Major subtypes include melasma (hormonally driven), post-inflammatory hyperpigmentation (PIH), and solar lentigines (sun spots). Involves upregulation of tyrosinase and melanosome transfer to keratinocytes.

Common Symptoms

Dark patches on face (melasma: cheeks, forehead, upper lip) Dark spots at sites of prior acne or injury (PIH) Age spots (solar lentigines) Uneven skin tone

Risk Factors

Sun exposure
Hormonal changes (pregnancy, oral contraceptives)
Skin inflammation or injury
Darker skin tones
Family history
Certain medications
