Melasma cream in Singapore what creams can fade, what they cannot, and what to avoid

The basics

What a melasma cream can and cannot do

Melasma is a long-term pigment condition that shows as symmetrical, soft-edged brown or grey-brown patches on the cheeks, forehead, upper lip or bridge of the nose. It is driven by ultraviolet and visible light, heat and hormones in people who are prone to it, and it is common in Asian women in Singapore.

Creams work by slowing the pigment system down. Some block tyrosinase, the enzyme that makes melanin; some slow the transfer of pigment into surrounding skin cells; others calm the inflammation and blood-vessel signals that feed the patches. They lighten existing pigment gradually and reduce new pigment, but they do not switch off the tendency to melasma.

Depth matters. Pigment in the upper skin responds to creams better than pigment in the deeper dermis, and many people have a mix of both. Creams also do little for look-alikes such as Hori's naevus or raised seborrhoeic keratoses, so a doctor should confirm that a patch is melasma before you spend months on any cream.

Side by side

Melasma and pigmentation creams compared

This is a map, not a prescription. Strength, formulation and how creams are combined matter as much as the ingredient, and most melasma trials were small and short.

Many people use more than one of these at different stages: a stronger prescription cream to fade the patches, then a gentler cream such as azelaic acid or a tranexamic acid serum for maintenance, with tinted sunscreen every day throughout.

Hydroquinone

Hydroquinone in Singapore: prescription-only, and why

Hydroquinone has been used to lighten pigment for decades and is still the ingredient most melasma creams are measured against. In Singapore it is treated as a medicine, not a cosmetic: the Health Sciences Authority (HSA) states that hydroquinone and tretinoin are potent ingredients used in prescription medicines, are prohibited in skincare cosmetic products and should only be used under strict medical supervision.

Supervision matters because of side effects. HSA warns that inappropriate use can cause rashes, redness, burning and changes in skin colour. The complication doctors watch for most is exogenous ochronosis, a blue-grey to blue-black darkening that can follow long-term or unsupervised use of lightening agents. It is uncommon, but a review of the condition stresses stopping the cause early because treatment options remain limited.

HSA has repeatedly found cosmetic creams, often sold online with promises of fast whitening, that contained undeclared hydroquinone, tretinoin or mercury. A cream that changes your skin dramatically within days, or that has no clear ingredient list, is a warning sign rather than a bargain.

• Use hydroquinone only when a doctor has prescribed it, at the strength and for the period agreed.
• Apply it only where directed, and keep it away from the eyes and the inside of the lips.
• Expect reviews: doctors usually plan breaks or step down to a gentler cream rather than continue indefinitely.
• Stop and contact the doctor if the skin burns or blisters, or if patches start to look grey or bluish.
• Tell the doctor if you are pregnant, planning a pregnancy or breastfeeding.
• Do not use unlabelled 'whitening' creams; mercury can harm the kidneys and nervous system.

Triple combination

Triple-combination cream: the strongest cream evidence

A triple-combination cream combines three generic ingredients: hydroquinone 4% to block pigment production, tretinoin 0.05% to speed skin turnover and help the hydroquinone work, and fluocinolone acetonide 0.01%, a mild steroid, to calm the irritation the other two can cause. Doctors may also prescribe similar compounded formulas.

In a Cochrane review of 20 randomised trials with 2,125 participants, triple-combination cream lightened melasma significantly more often than hydroquinone alone or any of the two-ingredient combinations. In the original eight-week studies, summarised in a later review, 29% of patients cleared completely by week eight and 77% were clear or almost clear.

Because it contains a steroid and a retinoid, it is a supervised course rather than a long-term moisturiser. In the published long-term studies, side effects were mostly mild redness, peeling or dryness where it was applied, and only two cases of skin thinning were reported, but steroid creams used on the face for long periods without review can thin the skin. Tretinoin should not be used in pregnancy or when trying to conceive.

Gentler creams

Azelaic acid, tranexamic acid, niacinamide and vitamin C

Azelaic acid slows pigment production and calms inflammation. In the Cochrane review, 20% azelaic acid lightened melasma more often than 2% hydroquinone and performed similarly to 4% hydroquinone. In Singapore the 20% cream is a prescription medicine, while lower-strength azelaic acid skincare is sold without a prescription. It suits maintenance and people who cannot use hydroquinone.

Tranexamic acid serums and creams target the signals that link UV exposure to pigment and small blood vessels. They are gentle and low-risk but slow; tranexamic acid tablets work faster but need a prescription and screening for clot risk.

Niacinamide slows the transfer of pigment to skin cells and is well tolerated, and vitamin C is an antioxidant that reduces melanin formation. Both give modest, gradual change, and suit a maintenance routine better than they suit established melasma on their own.

Cysteamine

Cysteamine cream: a newer non-hydroquinone option

Cysteamine is an antioxidant that occurs naturally in the body and reduces melanin production. It has drawn interest as an option for people who cannot use hydroquinone or need a break from it.

In a double-blind trial of 50 patients with epidermal melasma, cysteamine 5% cream used daily for four months lowered melasma severity scores more than a placebo cream (7.2 against 11.6 on the MASI scale), and skin colour measurements were better from two months onwards. Further trials have followed, but they are small and short.

Cysteamine can irritate, and how it compares with hydroquinone and triple-combination cream over the long term is still being studied. If you are considering it, ask a doctor whether it suits your type of melasma and how to fit it around other actives.

Sunscreen

Sunscreen with iron oxides: the cream that makes the others work

Every melasma cream works better when new pigment is not being triggered at the same time. Standard sunscreens filter UV, but visible light also darkens melasma in medium and darker skin. Iron oxides, the pigments that give tinted sunscreens their colour, help block visible light.

In a double-blind trial of 68 people with melasma, all using 4% hydroquinone, those given an SPF 50+ sunscreen containing iron oxide improved more over eight weeks than those using a UV-only SPF 50+ sunscreen: severity scores improved 15% more and skin colour measurements 28% more.

In Singapore, UV is high all year and strongest between 11am and 3pm. Apply a generous layer every morning, including office days by a window, reapply when you are outdoors, and use shade and a broad-brimmed hat. A tinted SPF or powder over make-up is a practical way to top up at lunch.

Rebound and relapse

Why melasma returns, and why lasers alone relapse

Melasma tends to come back. Creams fade the pigment, but the overactive pigment cells remain, so sun, heat or a hormonal change can bring the patches back within months. Stopping a cream abruptly without a maintenance plan is a common reason people feel treatment has failed.

Lasers can lighten melasma, but used on their own they tend to relapse. DermNet notes that Q-switched, fractional and picosecond lasers, intense pulsed light and microneedling carry a high risk of relapse and may make melasma more resistant to treatment. Too much heat can also trigger post-inflammatory darkening, which is common in Asian skin, so doctors keep energy low and treat laser as an add-on to creams and sunscreen, not a replacement.

A realistic plan has three layers: daily tinted sunscreen, a cream chosen for your skin, and, for some people, gentle laser or oral tranexamic acid prescribed after screening. Once the patches lighten, most plans step down rather than stop, and flares after a holiday, pregnancy or hormone change are easier to settle when treated early.

Where to go

Melasma creams and care in our network

At IN Eternity Clinic, 9 Scotts Road, #12-01 Pacific Plaza, beside Orchard MRT, Dr Sin Yong confirms whether a patch is melasma, sun spots, Hori's naevus or post-acne marks before planning treatment. Where suitable he prescribes topical or oral treatment and, for some people, adds low-energy Laser Toning or Pico Laser. Treatment is priced at consultation by the clinic; WhatsApp +65 8815 3008.

SkinRev Lab, at #B1-28 CityLink Mall by City Hall MRT, is a non-invasive centre and does not prescribe or inject. The Needleless SkinBooster with a pigmentation-and-tone booster (S$288 per region before GST) and HydraFacial Syndeo (S$288 to S$438 before GST) can support hydration and overall tone, and the shop stocks Heliocare 360° sunscreens, but none of these treats melasma.
