How to Differentiate Sunspots from Melasma
During facial skin examination, some women present with solar lentigines (sunspots), while others exhibit melasma. How can one distinguish between sunspots and melasma?
How to Differentiate Sunspots from Melasma
Melasma and sunspots can be difficult to distinguish visually; therefore, a professional medical evaluation at a hospital is necessary to confirm the diagnosis. Melasma typically appears as deeper, more diffuse pigmentation, whereas sunspots tend to be more superficial and well-defined. The underlying causes differ: melasma is primarily associated with hormonal imbalances—such as those occurring during pregnancy, with oral contraceptive use, or due to endocrine disorders—and may also result from unhealthy lifestyle habits. In contrast, sunspots arise predominantly from chronic ultraviolet (UV) radiation exposure. Treatment for both conditions should be tailored according to disease severity and may include topical medications or laser therapy.
Both sunspots and melasma can be treated using physical modalities, including intense pulsed light (IPL), Q-switched lasers, chemical peels (e.g., glycolic acid), and “porcelain doll” laser treatments. Individuals with sunspots are advised to consult qualified dermatologists at reputable hospitals to receive personalized, evidence-based treatment plans. Additionally, consistent use of medical-grade skincare products, increased dietary intake of vitamin C–rich fruits, and stress reduction techniques can help improve mood and reduce the incidence of facial hyperpigmentation.
Patients should practice rigorous sun protection when outdoors—applying broad-spectrum sunscreen is the most direct means of shielding the skin and minimizing UV-induced irritation. However, under conditions of intense UV exposure, sunscreen alone may be insufficient. Complementary protective measures—including wearing masks, sunglasses, long-sleeved clothing, and using umbrellas—can significantly reduce the probability of UV radiation reaching the skin surface, thereby achieving more comprehensive photoprotection.
