Melasma: Causes, Treatment & Why SPF Matters More Than Anything

Melasma can be one of the most frustrating skin conditions to treat and one of the easiest to accidentally make worse. In this episode of After Hours Skin Clinic, consultant dermatologists Dr Emma Craythorne and Dr Ellie Rashid take a deep dive into melasma, a common but often misunderstood form of hyperpigmentation. Emma and Ellie explore why melasma develops, why it’s so persistent, and the critical role that sun exposure, hormones, and genetics play in triggering and maintaining it. From pregnancy-related pigmentation to the impact of visible light (not just UV), this episode explains why managing melasma requires a long-term, consistent approach, not quick fixes. You’ll learn: What’s happening in the skin in melasma Why melanocytes become overactive and long-lasting The role of UV radiation and visible light Why daily sunscreen is the most effective prevention strategy Evidence-based treatments including hydroquinone, tretinoin, and azelaic acid When oral or topical tranexamic acid may be used The limits of over-the-counter skincare Why laser and light treatments must be approached with caution They also share practical advice on managing melasma day-to-day, including realistic expectations and ways to minimise its appearance. Key takeaway: Melasma is manageable but only if you consistently address the root cause, especially UV exposure.
