Hyperpigmentation Explained

Hyperpigmentation Explained — areas of skin that appear darker than the surrounding tone because of excess melanin. Common forms include post-inflammatory hyperpigmentation (after acne or injury), melasma (often hormonal) and sun-induced dark spots.

Key points

• Melanin overproduction is triggered by UV exposure, inflammation and hormones.
• Daily broad-spectrum SPF is the single most important step — without it, pigment treatments make little progress.
• Brightening actives include vitamin C, niacinamide, azelaic acid, alpha arbutin, tranexamic acid and retinoids.
• Pigmentation fades slowly; visible improvement usually takes 8–12 weeks or longer of consistent use.

Frequently asked

What is the fastest way to fade hyperpigmentation?

There is no instant fix: consistent sun protection plus a brightening active (such as vitamin C, azelaic acid or tranexamic acid) over 2–3 months gives the most reliable results.

Does sunscreen help with dark spots?

Yes — UV drives melanin production, so daily broad-spectrum SPF both prevents new spots and lets treatments work on existing ones.
