Melasma Cream: What Works, What Does Not and What the Evidence Says

Melasma is one of the most frustrating skin conditions to treat. The brown or grey-brown patches on the face are driven by a complex interplay of UV exposure, hormonal factors and inflammation, which is why no single cream eliminates it permanently. But the right combination of topical treatments can significantly reduce pigmentation and keep it under control.

A systematic review and meta-analysis of 45 studies involving 2,359 patients found that several topical agents, including hydroquinone, cysteamine, tranexamic acid and azelaic acid, demonstrated comparable efficacy in reducing melasma severity.[1] The differences between them lie in tolerability, safety profile and how well they work in combination. This guide covers what the clinical evidence supports, why combination therapy outperforms single ingredients, and how prescription formulas fit into a melasma management plan.

Key takeaways

• A meta-analysis of 45 studies confirmed that hydroquinone, cysteamine, tranexamic acid, azelaic acid and kojic acid all reduce melasma severity. Tranexamic acid had the lowest irritation rate (0.8%) while hydroquinone combinations had the highest (50.9%).[1]
• Triple combination cream (hydroquinone 4% plus tretinoin 0.05% plus fluocinolone 0.01%) resolved melasma in 80 per cent of 569 subjects at 12 months, making it the most effective single topical product.[2]
• A December 2025 meta-analysis confirmed that topical treatments significantly decrease both MASI scores and quality-of-life impact scores in melasma patients.[3]
• Topical tranexamic acid (2 to 5%) is emerging as a safe complement or alternative to hydroquinone, with growing evidence for both melasma and post-inflammatory hyperpigmentation.[4]
• Melasma requires ongoing management, not just treatment. Sun protection is non-negotiable, and maintenance therapy prevents the relapse that occurs in most patients who stop treatment.

What causes melasma and why it is hard to treat

Melasma is a chronic pigmentary disorder caused by overactive melanocytes in the epidermis and dermis. Unlike a simple dark spot from sun damage, melasma involves a feedback loop: UV exposure triggers melanin production, hormonal factors (pregnancy, oral contraceptives) amplify it, and inflammation sustains it. The blood vessels beneath melasma patches are also abnormally increased, which contributes to the persistence of the condition.[5]

This multi-pathway nature is precisely why single-ingredient creams rarely clear melasma on their own. An over-the-counter vitamin C serum or a low-concentration azelaic acid product can help at the margins, but it is not addressing enough of the melanin production cascade to produce a meaningful clinical result. Effective melasma treatment requires multiple depigmenting agents working through different mechanisms simultaneously.[6]

The evidence for melasma treatments

Triple combination cream: the gold standard

The most effective topical treatment for melasma remains the triple combination of hydroquinone, tretinoin and a low-potency corticosteroid. A comprehensive review noted that this combination resolved melasma in 80 per cent of 569 subjects at 12 months in clinical trials.[2] The definitive evidence-based review of melasma treatment (cited 297 times) confirmed triple combination cream as the first-line topical therapy.[7]

Each ingredient serves a specific role. Hydroquinone inhibits tyrosinase (the enzyme that produces melanin). Tretinoin accelerates epidermal turnover, dispersing melanin granules and enhancing hydroquinone penetration. The low-potency steroid reduces inflammation and minimises irritation from the other two actives. Used together, they target the melanin pathway at three different points.

Australian GPs and dermatologists commonly prescribe this combination for moderate-to-severe melasma. Practical guidance from the RACGP confirms it as a standard first-line approach in primary care, with monitoring for side effects during treatment.[8]

Hydroquinone: effective but requires supervision

Hydroquinone at 2 to 4 per cent is the single most studied depigmenting agent for melasma. The meta-analysis of 45 studies confirmed its efficacy, but also noted that hydroquinone combinations had the highest irritation rate at 50.9 per cent.[1] Long-term unsupervised use carries a risk of exogenous ochronosis (a paradoxical darkening of the skin), which is why hydroquinone is best used in supervised treatment cycles rather than continuously. For more detail on hydroquinone safety, see our skin bleaching cream guide.

Tranexamic acid: the emerging alternative

Tranexamic acid (TXA) is one of the most promising newer agents for melasma. A 2026 comprehensive review confirmed that topical TXA at 2 to 5 per cent reduces melanin synthesis through a different pathway to hydroquinone, making it an effective complement or alternative.[4] A focused review of 46 articles found that oral TXA was most effective for refractory melasma, while topical TXA was better tolerated than hydroquinone but less effective as a sole agent.[9]

The meta-analysis data showed TXA had the lowest irritation rate of any melasma treatment at just 0.8 per cent, compared to 50.9 per cent for hydroquinone combinations.[1] This makes it particularly valuable for patients with sensitive skin or those who cannot tolerate hydroquinone.

Azelaic acid

Azelaic acid at prescription strength (15 to 20%) inhibits tyrosinase and has anti-inflammatory properties that help with melasma. It is pregnancy-safe (Category B), which makes it one of the few active depigmenting options for pregnancy-related melasma. It works well as a maintenance agent or in combination with other actives. See our prescription skincare during pregnancy guide.

Vitamin C and niacinamide

Vitamin C inhibits tyrosinase and provides antioxidant protection against UV-driven melanin production. Niacinamide blocks melanosome transfer from melanocytes to keratinocytes. Neither is strong enough to clear melasma alone, but both add value as supporting ingredients in a multi-active prescription formula or as part of a morning antioxidant routine alongside sunscreen.[6]

Melasma treatment comparison

Why OTC melasma creams fall short

Over-the-counter melasma products typically contain low concentrations of a single active ingredient: vitamin C at 10 to 15 per cent, niacinamide at 5 per cent, or azelaic acid at 10 per cent. These concentrations can produce mild improvement over several months, but they do not match the efficacy of prescription-strength combinations.

The evidence is clear on this point. The meta-analysis data shows that combination therapy targeting multiple melanin pathways simultaneously produces significantly better outcomes than single-ingredient products.[7] An update on melasma treatments confirmed that multi-agent approaches remain the most effective strategy, with newer agents like tranexamic acid and cysteamine expanding the options available to prescribers.[6]

The role of sunscreen in melasma

No melasma cream will work without rigorous sun protection. UV exposure is the primary trigger for melanocyte activation, and even small amounts of unprotected sun exposure can reverse weeks of treatment progress. Broad-spectrum SPF 50+ every day is mandatory, not optional. In Australia, UV levels are high enough to trigger melasma even on overcast days.

Visible light can also worsen melasma, which is why tinted sunscreens containing iron oxide are recommended. The iron oxide filters visible light wavelengths that standard UV filters do not block. For more on sunscreen types, see our physical sunscreen guide.

Building a melasma treatment routine

Morning

Gentle cleanser, vitamin C serum (optional antioxidant support), moisturiser, tinted broad-spectrum SPF 50+. The tinted sunscreen provides both UV and visible light protection.

Evening

Gentle cleanser, prescription melasma formula (such as a custom-compounded cream from Prescription Skin), moisturiser. The prescription active does the depigmenting work overnight. See our skincare routine guide for the full framework.

Frequently asked questions

What is the best cream for melasma?

Triple combination cream (hydroquinone plus tretinoin plus a low-potency steroid) has the strongest evidence, with 80 per cent resolution in clinical trials.[2] It is prescription-only and should be used under medical supervision.

Can melasma be cured permanently?

Melasma is a chronic condition. It can be significantly reduced and controlled, but most patients need ongoing maintenance treatment and strict sun protection to prevent relapse. Stopping treatment without a maintenance plan usually leads to recurrence.

Is tranexamic acid good for melasma?

Yes. A comprehensive review confirmed topical tranexamic acid at 2 to 5 per cent reduces melasma with the lowest irritation rate of any studied agent (0.8%).[1] It is particularly useful for patients who cannot tolerate hydroquinone.

Is melasma treatment safe during pregnancy?

Hydroquinone and tretinoin are not recommended during pregnancy. Azelaic acid (Category B) is one of the few active options. Sun protection remains the most important step. See our prescription skincare during pregnancy guide.
