Evidence-Based Best Practices for Melasma Care

Melasma is a stubborn skin condition that causes brown or grayish patches, most often on the face. It primarily affects women, especially those with darker skin types, and is frequently triggered by sun exposure, hormonal changes, and heat.

Dermatologists now emphasise that managing melasma requires a multi-pronged approach. There is no single cure, but a combination of strategies can significantly reduce pigmentation and prevent recurrence.

The Sun Protection Foundation

Broad-spectrum sunscreen is non-negotiable. Experts recommend a physical blocker with zinc oxide or titanium dioxide, applied daily without fail. Sunscreens with iron oxides offer added protection against visible light, which can also worsen melasma.

Reapplication every two hours, especially for those outdoors, is critical. Hats and sunglasses provide additional physical defence.

Topical Therapies: First-Line Defence

Topical medications remain the backbone of treatment. A combination of hydroquinone, tretinoin, and a mild steroid is a classic regimen, but must be used under medical supervision. Hydroquinone should not be used continuously for more than a few months without a break.

Alternatives like azelaic acid, kojic acid, and niacinamide are also effective, especially for long-term maintenance. These can be used for months without the risks associated with hydroquinone.

Procedural Options for Stubborn Cases

When topicals alone are insufficient, in-office procedures can help. Chemical peels using glycolic acid or trichloroacetic acid are common. Microneedling with tranexamic acid has shown promising results.

Laser and light-based therapies, such as the Q-switched Nd:YAG and intense pulsed light, can target pigment. However, these carry a risk of post-inflammatory hyperpigmentation, especially in darker skin. Patient selection and device settings must be carefully managed.

Lifestyle and Maintenance

Avoiding heat sources like saunas, steam rooms, and even hot yoga can reduce flare-ups. Heat is a known trigger for melasma. Gentle skincare routines that avoid irritation are equally important.

Patients must understand that melasma is a chronic condition. Maintenance therapy with non-hydroquinone topicals and consistent sun protection is essential to keep the skin clear.

Dermatologists also counsel patients on realistic expectations. Improvement takes time, and complete clearance is not always possible. The goal is control, not cure.

Looking ahead, research continues into novel therapies. Tranexamic acid, both oral and topical, is gaining attention. Further studies will clarify its role and long-term safety.
