Topical tranexamic acid
Melasma serum trend
Tranexamic acid moved from an operating-theatre drug to a serum shelf staple; beauty editors call it a 'holy grail' brightener and melasma forums discuss it as the hydroquinone alternative.
Search interest: about 2,900 searches a month in Singapore for “tranexamic acid” (Ahrefs, October 2026).
It treats the inflammation that makes melasma, which is the half of the problem lasers cannot touch.

Does Topical tranexamic acid work?
Promising. It treats the inflammation that makes melasma, which is the half of the problem lasers cannot touch. A 2024 meta-analysis of randomised trials found tranexamic acid, topical and oral, improved melasma scores, with topical forms roughly comparable to hydroquinone in several head-to-head RCTs and better tolerated.
- Verdict
- Promising Plausible mechanism and early evidence. Reasonable to try with realistic expectations.
- Evidence base
- 3 PubMed-indexed studies cited below, including systematic reviews, randomised trials.
- Suits
- Melasma and post-inflammatory marks in people who want a non-hydroquinone option, especially alongside strict sun protection and a retinoid.
- Not for
- Anyone expecting erasure in weeks. It will not treat dermal pigment on its own, and it is not a substitute for sun protection.
- In Singapore
- Topical tranexamic acid at cosmetic strengths is sold in Singapore as a notified cosmetic.

What it is
Tranexamic acid is a synthetic amino-acid derivative used in medicine to reduce bleeding. Applied to the skin at two to five per cent it is used to lighten melasma and post-inflammatory marks. The oral form is a prescription medicine and a separate conversation.
How it works
Melasma pigment is driven partly by ultraviolet-triggered plasmin activity in keratinocytes, which releases signals that switch melanocytes on. Tranexamic acid blocks plasminogen activation, so it dampens the signal rather than bleaching the pigment already made. Concentration, vehicle and whether it is paired with microneedling or a retinoid change the result; it is slow, and works on the inflammatory side of melasma rather than the melanin itself.
What the evidence says
A 2024 meta-analysis of randomised trials found tranexamic acid, topical and oral, improved melasma scores, with topical forms roughly comparable to hydroquinone in several head-to-head RCTs and better tolerated. One double-blind split-face RCT compared 3% tranexamic acid cream with 4% hydroquinone in skin of colour and found similar improvement. Microneedling-assisted delivery has its own systematic review with modest additional benefit. The weaknesses are short follow-up, small trials and the usual melasma relapse once treatment stops.

What the studies show
- systematic review
Pooled RCT data showed tranexamic acid reduced melasma severity scores versus comparators, with a favourable side-effect profile for topical use.

- RCT
Both creams improved mixed-type melasma over the study period with no significant difference in efficacy and fewer irritant effects with tranexamic acid.

- systematic review
Microneedling with topical tranexamic acid improved melasma scores more than several comparators, with mild transient side effects.

Who it suits

Not for
Anyone expecting erasure in weeks. It will not treat dermal pigment on its own, and it is not a substitute for sun protection.
Alternatives
The two reviewed treatments most often weighed against Topical tranexamic acid, on the same standard.
| Topical tranexamic acid | Niacinamide | Retinoids | |
|---|---|---|---|
| Verdict | Promising | Established | Established |
| What it is | Tranexamic acid is a synthetic amino-acid derivative used in medicine to reduce bleeding. | Niacinamide is vitamin B3 in its amide form, a water-soluble ingredient used at two to ten per cent in serums and moisturisers. | Retinoids are vitamin A derivatives applied to the skin. |
| Evidence base | 3 PubMed-indexed studies cited below, including systematic reviews, randomised trials. | 3 PubMed-indexed studies cited below, including randomised trials. | 4 PubMed-indexed studies cited below, including systematic reviews, randomised trials. |
| Suits | Melasma and post-inflammatory marks in people who want a non-hydroquinone option, especially alongside strict sun protection and a retinoid. | Almost everyone: oily, blotchy, acne-prone or barrier-compromised skin, and as a tolerable companion to retinoids and acids. | Adults with acne, fine lines, uneven texture or sun damage who will use it most nights for months; it is the base layer most clinic plans sit on. |
| In one line | It treats the inflammation that makes melasma, which is the half of the problem lasers cannot touch. | It will not change a face, but it makes everything else in the routine easier to tolerate, which is worth more than most hero ingredients deliver. | The mistake is not choosing the wrong retinoid; it is quitting in week three. |
Risks
Mild irritation and dryness; rare contact allergy. The oral form carries clotting-related cautions and needs a doctor.
In Singapore
Topical tranexamic acid at cosmetic strengths is sold in Singapore as a notified cosmetic. Oral tranexamic acid is a prescription-only medicine, is not advertised to the public, and is prescribed only after a doctor assesses clotting risk; this is an editorial review, not an offer.
