Melasma Treatment in Asian Skin: Why Stronger Isn’t Always Better

Treating melasma in Asian skin requires a careful, layered approach. Many Asian skin types are prone to post-inflammatory hyperpigmentation (PIH), meaning that excessive irritation can worsen the very pigmentation we are trying to treat.

For me, successful melasma treatment starts with a simple principle: respect the epidermis and protect the skin barrier.

A healthy skin barrier comes first

The epidermis is not simply a surface we need to penetrate to reach pigment. It is a sophisticated protective barrier. When it is disrupted, dryness, sensitivity and inflammation follow. In pigment-prone skin, that inflammation can stimulate melanocytes and lead to further pigmentation.

This is why I am cautious about excessive exfoliation, strong acids and overly aggressive procedures. Sometimes the first step in treating melasma is actually to do less: simplify skincare, restore hydration and barrier function, and calm inflammation before introducing pigment-correcting treatments.

Photoprotection means more than SPF

Melasma is more complex than excess melanin. Hormonal influences, inflammation, oxidative stress, vascular changes and chronic light exposure all play a role.

For this reason, photoprotection is part of the treatment itself.

• UVB protection

• UVA protection, particularly long-wave UVA1

• Visible-light protection, including high-energy visible or blue light

• Hats, shade and avoidance of excessive solar and heat exposure

SPF primarily measures UVB protection. For melasma, I look for broader protection from UVB, UVA (particularly long-wave UVA1) and visible light, including high-energy visible or blue light. Tinted sunscreens containing iron oxides can provide useful visible-light protection that conventional untinted sunscreens may not.

I also encourage hats, shade and avoidance of excessive solar and heat exposure. Near-infrared (NIR) radiation is increasingly recognised in relation to oxidative stress and photoageing, although its specific contribution to melasma is less established than UV and visible light.

In other words, for melasma, SPF 50 is not the whole story.

Treating melasma is like cooking

A good dish rarely relies on one very strong spice. It comes from combining several ingredients in the right amounts and adding them at the right time.

Melasma treatment is much the same.

The foundation of my “recipe” is barrier repair and comprehensive photoprotection. I may then layer pigment-regulating skincare containing ingredients such as niacinamide, azelaic acid and arbutin.

• Barrier repair

• Comprehensive photoprotection

• Pigment-regulating skincare such as niacinamide, azelaic acid and arbutin

• Prescription treatment where appropriate and medically supervised

For more established pigmentation, I may prescribe modified Kligman’s formula, also known as triple-combination cream. This combines hydroquinone, which reduces melanin production; a retinoid such as tretinoin, which increases epidermal cell turnover; and a mild topical corticosteroid, which helps control irritation and inflammation.

It is one of our best-established topical treatments for melasma, but I prefer to use it in planned, supervised treatment phases while closely monitoring epidermal integrity.

What about lasers for melasma?

Lasers require particular caution in Asian skin. Too much heat or inflammation can cause PIH or rebound pigmentation.

However, carefully selected fractional picosecond 1064-nm laser treatment, such as PicoWay Resolve 1064 nm, can be useful as an adjunct when topical treatment has reached a plateau.

The important word is gentle. Melasma is not something I try to remove in one or two aggressive laser sessions. Lower-intensity fractional treatment aims for gradual improvement while minimising epidermal injury.

Patients need realistic expectations: multiple sessions over several months may be required. Studies in Asian patients using fractional picosecond 1064-nm lasers have demonstrated improvement with repeated treatments, including protocols involving up to nine sessions at 4–6-week intervals.

Laser is therefore another ingredient in the recipe — not the entire recipe.

Gentle does not mean ineffective

There can be an assumption that redness, peeling or inflammation means a pigmentation treatment is working. In Asian skin, this can be counterproductive.

The objective is not to strip away the epidermis to reach pigment. It is to regulate pigment production while keeping the epidermis healthy and resilient.

Melasma is a chronic, relapsing condition. Successful management requires patience, maintenance and intelligent combinations of treatment.

Much like cooking, one powerful spice rarely makes the best dish. For melasma in Asian skin, barrier repair, broad-spectrum photoprotection and carefully layered pigment treatments should work together — not against each other.
