Melasma Treatment Time

Melasma Treatment Duration

Melasma is a chronic facial hyperpigmentation. It usually shows up when hormonal factors (pregnancy, oral contraceptives) meet UV/visible light exposure. For the active depigmenting phase, a rough rule of thumb is months ≈ 4 + intensity × 2. In practice that means most people see visible clearing somewhere in the 4–12 months range, then stay on maintenance indefinitely.

The classical approach is the Kligman formula (hydroquinone 4% + tretinoin 0.05% + fluocinolone 0.01%) applied nightly. When a case resists treatment, doctors often add oral or topical tranexamic acid. One thing is non-negotiable: broad-spectrum SPF 50+ with iron oxides is MANDATORY daily. Skip the strict photoprotection and no protocol will work. Because post-inflammatory hyperpigmentation (PIH) and rebound flares happen so often, melasma is treated as a relapsing condition, and the SBD (Sociedade Brasileira de Dermatologia) and SADM (Sociedade de Dermatologia Mexicana) consensus documents reflect that.

Applications

Handy when you want to set realistic expectations, plan sun-exposure windows so summer doesn't undo your progress, budget for compounded prescriptions, or time things around a change in hormonal contraception. Treat it as educational only. A dermatologist has to tailor the actual melasma protocol to you.

FAQ

Does melasma come back? It can. Melasma is chronic, so even after the skin clears you still need daily SPF 50+ and a bit of seasonal maintenance to keep it from returning.

Is laser a first-line option? No. Aggressive lasers can actually make melasma worse by triggering PIH. Start with topicals and rigorous photoprotection. Lasers are kept in reserve for cases that don't respond, and only under specialist supervision.

Is this a substitute for medical advice? No. Both hydroquinone and tranexamic acid need a prescription, so see a dermatologist registered with SBD/CRM.
