Treating Melasma Safely: An Evidence-Based Approach for Aesthetic Practitioners
Few conditions test an aesthetic practitioner’s judgement like melasma. It is common, it disproportionately affects women and people with darker skin tones, and — crucially — the wrong treatment can make it visibly worse. Understanding why melasma behaves the way it does is the first step to treating it responsibly.
What melasma is
Melasma is a chronic disorder of pigmentation that produces symmetrical brown or grey-brown patches, most often on the cheeks, forehead, upper lip and chin. Its development is driven by a combination of factors: ultraviolet and visible light exposure, hormonal influences (pregnancy and oral contraception are common triggers) and a genetic predisposition [1]. Heat itself may also be a factor, which is one reason energy-based devices must be approached carefully.
Because it is chronic and relapsing, melasma is best framed to patients as a condition to be managed rather than permanently “cured” — a conversation worth having at the very first visit.
Assessment before treatment
A careful assessment guides everything that follows. A Wood’s lamp can help gauge whether pigment is predominantly epidermal or dermal, which influences the likely response to treatment — dermal and mixed pigment tends to be more stubborn. Documenting triggers, current skincare, photoprotection habits and previous treatments (including any that worsened the condition) is essential.
First-line treatment: protection and topicals
Effective melasma care almost always begins conservatively:
- Rigorous photoprotection is the foundation. Broad-spectrum sunscreen that also covers visible light — tinted formulations containing iron oxides are particularly useful — applied daily and reapplied, does more than any device.
- Topical depigmenting agents remain first-line. Triple-combination therapy (a retinoid, a corticosteroid and hydroquinone) has the strongest evidence, with alternatives such as azelaic acid, tranexamic acid and others for maintenance or where hydroquinone is unsuitable [2].
These measures are unglamorous but are where real, durable improvement comes from.
Why devices and peels demand caution
This is the heart of safe melasma practice. Aggressive resurfacing lasers, IPL and deep chemical peels can trigger post-inflammatory hyperpigmentation and, at times, a rebound that leaves the patient worse than before — especially in darker phototypes. Where procedural treatment is considered, it is generally as an adjunct to topicals and photoprotection, using conservative settings, superficial peels and carefully selected low-energy device protocols, ideally after the condition is stabilised. Test areas and gradual escalation are prudent.
Counselling and the practitioner’s role
Managing expectations is part of the treatment. Patients should understand that improvement is gradual, that maintenance and sun protection are lifelong, and that relapses can happen with sun exposure or hormonal change. A practitioner who resists the temptation to “blast” melasma with a device — and instead builds a patient, layered plan — delivers better and safer outcomes.
Melasma is an area where knowing when not to treat aggressively is a mark of expertise. Structured training that covers skin-type assessment, pigment disorders and complication management gives practitioners the judgement to treat this condition well.
