The Challenge of Melasma
Melasma presents as symmetrical brown or greyish-brown patches, most commonly on the cheeks, forehead, nose bridge, upper lip, and chin. It is one of the most frequently seen pigmentation disorders in Dubai, driven by the combination of intense UV exposure, heat, and the hormonal profiles of the population.
While melasma is not medically dangerous, its impact on quality of life and self-confidence is well documented. It is also one of the most challenging pigmentation conditions to treat, because it tends to recur even after successful clearance.
What Causes Melasma?
Melasma results from overactive melanocytes, the cells that produce skin pigment. Several factors stimulate this overproduction:
- UV and visible light exposure, The single most important trigger. Even brief sun exposure can reactivate melasma after treatment.
- Hormonal changes, Pregnancy ("mask of pregnancy"), oral contraceptives, and hormone replacement therapy are well-established triggers
- Heat, Infrared radiation and ambient heat can stimulate melanocytes independently of UV
- Genetic predisposition, Melasma is more common in individuals with Fitzpatrick skin types III to VI
- Thyroid dysfunction, An underactive thyroid has been associated with melasma in several studies
Treatment Strategy
Successful melasma management requires patience and a multi-pronged approach:
1. Rigorous sun protection, This is non-negotiable. SPF 50+ broad-spectrum sunscreen with iron oxide (tinted) should be applied every morning and reapplied every two hours when outdoors. A wide-brimmed hat adds further protection.
2. Topical depigmenting agents, Hydroquinone (prescription-strength), azelaic acid, tranexamic acid, kojic acid, and arbutin can all reduce melanin production. Combination formulations tend to be more effective than single agents.
3. Chemical peels, Superficial peels (glycolic, lactic, mandelic) can help lift surface pigment. Deeper peels must be used cautiously to avoid post-inflammatory hyperpigmentation.
4. Oral tranexamic acid, Low-dose oral tranexamic acid has emerged as a promising treatment for stubborn melasma, with several clinical trials demonstrating significant improvement.
5. Laser therapy, Low-fluence Q-switched lasers can be effective but carry a risk of rebound hyperpigmentation. They are best reserved for cases that do not respond to topical and oral therapy.
What to Avoid
- Aggressive treatments that damage the skin barrier (strong peels, high-energy lasers)
- Inconsistent sunscreen use, even one day of unprotected exposure can undo weeks of progress
- Unrealistic expectations, melasma is managed, not cured. Maintenance therapy is essential.
Our Approach at Al Das
Our dermatologists combine topical therapy, in-clinic treatments, and hormonal assessment to create a comprehensive melasma management plan. We also investigate potential contributing factors such as thyroid function and vitamin D levels, because addressing the internal drivers often improves treatment response.
