Hyperpigmentation in Black skin: what helps dark spots fade?

What causes the dark spots?

Hyperpigmentation means darkening caused by excess pigment. Melanin gives skin its colour, and pigment cells in darker skin produce more of it. Skin injury and inflammation can stimulate additional pigment production, making the marks more noticeable and persistent in darker skin tones. Hyperpigmentation is a description, not one diagnosis: marks after acne and patches caused by melasma need different treatment decisions.345

Melasma is more common in women, especially during pregnancy. Hormonal pigmentation can also affect the abdomen and other areas during pregnancy. These changes are not necessarily PIH, so do not assume that every new patch needs the same treatment as an old acne mark.24

What should you do first?

1. 1Address the trigger. Treat active acne, eczema or another inflammatory condition rather than treating only the pigment left behind.
2. 2Remove avoidable irritation. Choose gentler skin and hair care, and stop using a cosmetic product that burns or stings.
3. 3Protect exposed skin daily. Use sunscreen before going outside, then add a pigment treatment if needed.

A fading product cannot stop new marks from an untreated trigger, however ambitious the name on the bottle.1

Which sunscreen helps with pigmentation?

Choose a tinted, water resistant sunscreen with iron oxide, broad spectrum protection and SPF 30 or higher. Iron oxide protects against visible light, which can contribute to dark spots. Look for it in the inactive ingredient list and choose a tint that blends with your skin tone. Apply sunscreen to skin that clothing will not cover, and reapply every two hours outdoors and after swimming or sweating.1

For exposed pigmentation, daily broad spectrum SPF 50 or higher helps minimise further darkening from ultraviolet light. Sun protection reduces a trigger for pigmentation; it does not remove pigment lodged deep in the skin. A wide brimmed hat adds protection outdoors.14

Which treatments are worth considering?

Topical treatments, meaning products applied to the skin, are usually the first treatment option. Hydroquinone is an established treatment for facial hyperpigmentation, used alone or in combinations. Retinoids and azelaic acid are other options, but irritation matters particularly in richly pigmented skin because inflammation can leave another dark mark.2

For sensitive or easily irritated skin, preventing treatment related inflammation is part of treating the pigmentation itself. A dermatologist can choose and combine treatments when a cosmetic product is not giving enough improvement. The appropriate combination depends on whether the problem is melasma, PIH or another cause, rather than simply how dark the patch looks.15

How long does fading take?

After the trigger stops, a spot a few shades darker than your natural skin colour usually fades within 6 to 12 months. Deeper pigment can take years and often looks slate blue, grey or much darker brown. Treatment can speed fading.1

For PIH in darker skin, improvement is more common than complete clearing. Across reported treatment outcomes, topical retinoids produced partial improvement in 85% of participants, while lasers produced partial improvement in 66%. These were separate treatment groups, not a direct comparison. Treat these figures as expectations for gradual improvement, not a reason to choose a laser over a cream.5

Cosmetic camouflage can cover uneven colour while you treat it, without requiring your concealer to practise dermatology.4

Can lasers or peels make pigmentation worse?

Yes. Lasers and chemical peels can improve pigmentation, but procedures that injure the skin can also create more pigment. Some people achieve complete clearing with laser treatment, while others develop worsening PIH. Richly pigmented skin needs particular caution when selecting a procedure. Cryotherapy, which freezes the skin, also carries a risk of permanent lightening.45

When should you get a dark patch checked?

Get unexplained pigmentation assessed before treating it as an acne mark. Dark patches can also come from infections, thickened skin, benign growths or skin cancer. Widespread darkening has different possible causes from a single healed spot, including medical conditions that affect pigment production.34

Seek medical assessment for a spot that changes size, develops an irregular shape or uneven colour, itches or bleeds. Melanoma can occur in Black skin, including on palms, soles and beneath nails. Those changes need examination rather than another fading product.6

New pale patches are not the same as dark spots fading evenly. Injury, medications and cosmetic procedures can reduce pigment. If light areas spread, worsen or remain unchanged after a few weeks, see a dermatologist instead of treating the light spots yourself.7

If you suspect a prescribed medication is causing darkening, ask the prescriber about it rather than stopping treatment yourself. Never apply liquid bleach to skin.1
