Melasma isn't just darker pigmentation. It's a different condition with different triggers, and it punishes routines that treat it like ordinary hyperpigmentation.
If you've followed a standard brightening routine and your melasma got worse instead of better, that's not unusual. We hear this from women constantly. The retinoid that fades PIH effectively can irritate melasma-prone skin enough to trigger a flare. The AHA that clears post-acne marks can weaken a barrier that melasma needs intact. Even sunscreen, the universal first recommendation, may not be doing enough if it's untinted.
Melasma requires a routine built specifically around its sensitivities. Not a gentler version of a normal routine. A structurally different one.
Why melasma is different
Three characteristics separate melasma from other forms of hyperpigmentation, and they all point to triggers that go deeper than the skin's surface.
It responds to heat, not just UV. Most hyperpigmentation is primarily UV-driven. Melasma adds heat sensitivity through pathways that have nothing to do with ultraviolet light. Infrared radiation, steam, hot environments, and even emotional flushing can trigger pigment production in melasma-prone skin. Your routine has to account for heat, not just UV.
It responds to visible light. Standard broad-spectrum sunscreen blocks UVA and UVB but not visible light, particularly the blue-violet wavelengths that stimulate melanocytes through the opsin-3 pathway. For melasma, this gap is significant. A tinted sunscreen with iron oxides isn't optional. It's a core requirement.
It has a lower irritation threshold. Melasma-prone skin tends to react more strongly to actives, and that reaction itself drives pigment production. The margin between "effective treatment dose" and "irritation that triggers a flare" is narrower than for PIH or sun spots. Routines that work fine for other pigment types can be too aggressive for melasma.
What makes all of this harder to manage is that melasma's triggers aren't only environmental. Hormonal fluctuations, systemic inflammation, and stress all drive pigment production from the inside. That's part of why topicals alone often aren't enough. You can control your sunscreen and your water temperature, but you can't topically address a hormonal signal or a body-wide inflammatory response. Melasma sits at the intersection of surface triggers and internal drivers, and a routine that only covers one layer is always going to have gaps.
For more on how melasma works and how it's treated beyond the routine level, the hyperpigmentation treatments guide covers the full picture.
The melasma-safe morning routine
Morning protection for melasma is more demanding than for other pigment types because the trigger profile is wider.
1. Gentle cleanser
Lukewarm water only, or the mildest cleanser you have. Hot water can trigger pigment production in melasma-prone skin. This isn't an exaggeration. Heat of any kind, including water temperature, contributes to the flushing and inflammation that drive melasma flares.
2. Antioxidant serum
Vitamin C (ideally a gentle derivative like ethylated ascorbic acid or ascorbyl glucoside) applied before sunscreen. This adds a layer of free radical defence and mild tyrosinase inhibition. Avoid high-concentration L-ascorbic acid if it irritates your skin. For melasma, the derivative's lower irritation profile outweighs the slightly slower results.
3. Tinted mineral sunscreen, SPF 50
This is the most important topical step in a melasma routine, and it's more specific than the general sunscreen recommendation:
Mineral filters preferred. Zinc oxide and titanium dioxide sit on the skin surface and provide broad UV protection without the potential irritation of some chemical filters.
Must contain iron oxides. This is what makes it tinted. Iron oxides block visible light wavelengths that untinted sunscreens miss entirely. For melasma, visible light is a meaningful trigger, and this is the only way to address it topically. Why tinted sunscreen matters for hyperpigmentation covers the evidence in detail.
Apply generously. The SPF and visible light protection both depend on application thickness. A thin layer gives you a fraction of the labelled protection. Use more than feels natural.
Reapply every two hours when outdoors. This applies year-round for melasma, not just in summer.
4. Internal support
Melasma's strongest drivers are hormonal and inflammatory, and no topical can reach them. A targeted supplement that supports antioxidant defence, helps regulate inflammation, and provides the micronutrients your skin needs to manage pigment production is doing work that your serum and sunscreen can't. For melasma specifically, the inside-out approach isn't supplementary to the routine. It's covering the gap that topicals leave open.
5. Physical barriers
A wide-brimmed hat whenever you're outside adds protection that no sunscreen can fully replicate. For people whose melasma is on the forehead and cheeks, hat shade directly over the affected areas reduces UV, visible light, and heat exposure simultaneously.
The melasma-safe night routine
Night is the treatment window, but for melasma, the active choices and concentrations need to be carefully calibrated.
1. Gentle double cleanse
Oil cleanser to remove sunscreen, followed by a gentle water-based cleanser. Lukewarm water. No foaming agents, no fragrance.
2. One gentle active
The most effective and well-tolerated options for melasma:
Tranexamic acid: One of the best-studied ingredients for melasma specifically. It works by interrupting the signals between UV damage and the pigment response. Well-tolerated, minimal irritation risk, can be used nightly. This is often the best first-line active for a melasma routine.
Azelaic acid (15-20%): Anti-inflammatory and a tyrosinase inhibitor. Strong evidence for melasma specifically. Can cause mild tingling initially but is generally well-tolerated once skin adjusts. Start every other night and build to nightly.
Cysteamine (5%): A newer ingredient with strong early evidence for melasma. Works on multiple points in the pigment pathway. Can cause temporary odour and mild irritation in some people. Apply for a set period (typically 15-20 minutes), then remove.
Low-concentration retinoid: Tretinoin at 0.025% or retinaldehyde, used once or twice a week, can support fading by increasing cell turnover. But the irritation risk is real for melasma, and it should only be introduced after your barrier is stable and your gentler actives are well-established. Buffer over moisturiser and increase frequency very slowly.
What to approach with caution or avoid:
- Glycolic acid at any concentration above 5%. The barrier disruption risk outweighs the benefit for melasma. If you want to exfoliate, mandelic acid or lactic acid at low concentrations are gentler options.
- High-concentration L-ascorbic acid. If it causes any stinging, switch to a derivative.
- Hydroquinone above 2% without medical supervision. It's effective but carries rebound risk if used incorrectly, and melasma-prone skin is more susceptible to rebound.
3. Barrier-supportive moisturiser
Ceramides, squalane, or fatty acid-rich formulas. The barrier is your first line of defence against the environmental triggers that drive melasma, and every product choice should either support it or at least not weaken it.
On active nights, applying moisturiser generously after your treatment provides a buffer that reduces irritation without meaningfully reducing the active's effectiveness.
Heat management in your routine
This is the element that doesn't appear in standard hyperpigmentation routines but is critical for melasma:
Lukewarm or cool water for cleansing. Not hot. Hot water causes blood vessels to dilate and triggers pigment production.
Avoid applying products immediately after heat exposure. If you've just finished cooking, exercising, or been in a hot car, let your skin cool down before your evening routine. Applying actives to heated, flushed skin increases penetration unpredictably and increases irritation risk.
Be cautious with occlusive products in warm conditions. Heavy occlusives can trap heat against the skin. In warm weather or heated indoor environments, lighter moisturisers may be better tolerated.
Consider thermal water mists. Some people with melasma find that a thermal water spray used throughout the day helps manage heat-related flushing. The evidence is limited, but the cooling effect is real and the risk is essentially zero.
Why melasma routines have to be more patient
Melasma is chronic. Unlike PIH, which is a response to a specific event and follows a fading trajectory once the event resolves, melasma is driven by ongoing factors: hormones, UV, visible light, heat, and potentially genetics. The signals driving pigment production don't fully stop.
That's not just an inherent limitation of the condition. It's a sign that melasma's drivers operate on two layers. Your topical routine handles the surface layer: UV, visible light, heat reaching the skin, barrier integrity. But the hormonal fluctuations and systemic inflammation that keep melanocytes primed to overproduce don't live on the surface. They're internal, and they keep running even when your topical routine is perfect. This is why someone can do everything right externally and still see flares during hormonal shifts or high-stress periods.
Addressing both layers doesn't guarantee faster results, but it means your routine isn't fighting with one hand behind its back. When you're supporting your skin from the inside, through the inside-out approach, the topical work you're doing has a better foundation to build on.
That still requires patience. If you've been consistent for months and the change is subtle, that's normal for melasma. It's not that the routine isn't working. It's that the condition's nature means improvement is slower and more vulnerable to setbacks than other pigment types.
If you've been checking your skin every morning and feeling like nothing's changing, the frustration is completely valid. Melasma moves slowly, and living with it while waiting for treatment to work is harder than most people acknowledge. But slow, steady, gentle treatment that stays well below the irritation threshold will produce real results. It just asks more of your patience than it should have to.
When to involve a dermatologist
Melasma often benefits from prescription-level treatment alongside a good topical routine. If your over-the-counter routine is holding but not advancing, a dermatologist can assess whether prescription options like higher-concentration tretinoin, combination formulas (such as triple combination therapy), or oral tranexamic acid might accelerate your progress.
If your melasma flares frequently despite a careful routine, or if it appeared during pregnancy or hormonal treatment and hasn't resolved, a dermatologist can help identify whether hormonal management might be part of the approach.
The routine is the foundation. But for melasma specifically, professional guidance often makes the difference between holding steady and actually gaining ground.
