Melasma Treatment
Melasma is one of the most challenging pigmentation conditions to treat, characterised by symmetrical, brownish-grey patches that typically appear on the forehead, cheeks, upper lip, and chin. Often triggered or worsened by hormonal changes, sun exposure, and heat, melasma can be particularly frustrating because it is resistant to many standard pigmentation treatments. At Skin Health Practice in Hounslow, we specialise in evidence-based melasma management using the Cosmelan depigmentation system, medical-grade mesoestetic peels, and complementary therapies designed to tackle this complex condition at its root.

Understanding Melasma
Unlike simple sun spots or post-inflammatory hyperpigmentation, melasma involves a chronic overactivity of melanocytes — the pigment-producing cells in the skin. Hormonal factors play a significant role, which is why melasma frequently develops during pregnancy (often called the 'mask of pregnancy'), while taking oral contraceptives, or during hormone replacement therapy. UV exposure and heat are major triggers that can worsen existing melasma or cause it to recur after treatment. Managing melasma requires an approach that not only clears existing pigmentation but also addresses the underlying melanocyte dysfunction.
The Cosmelan Depigmentation System
Cosmelan is the world's leading professional depigmentation treatment and our primary tool for treating melasma. It works by inhibiting the enzyme tyrosinase, which is essential for melanin production, while also accelerating cell turnover to remove existing pigmented cells. The treatment involves an in-clinic application of the Cosmelan mask, followed by a structured at-home protocol over several weeks. Cosmelan has been clinically proven to reduce melasma pigmentation by up to 95% and is effective across all skin types.
Complementary Therapies and Maintenance
For the best long-term results, we often combine Cosmelan with other treatments. Dermalux LED therapy helps reduce inflammation and supports skin healing during the depigmentation process. Medical-grade mesoestetic peels can further refine skin tone and texture once the primary depigmentation is complete. A rigorous daily SPF regimen is essential, as even brief UV exposure can reactivate melasma. We provide comprehensive aftercare guidance and ongoing support to help you maintain your results.
