Among skin problems, melasma and freckles are two common pigmentation disorders, but their causes, manifestations, and treatments are quite different. Many people are confused about the difference between these two types of spots. This article will analyze their differences in detail and help you better understand through structured data.

5. Summary
Although melasma and freckles are both common pigmentation problems, there are significant differences in their causes, presentation, and treatment. Chloasma is mostly related to hormones and ultraviolet rays, and manifests as flaky patches, making it difficult to treat. Freckles, on the other hand, are mainly related to genetics, manifesting as dot-like spots, and are relatively simple to treat. No matter what kind of blemishes you have, sun protection is key. If you are unsure about the type of spot you have, it is recommended to consult a professional dermatologist for an accurate diagnosis and personalized treatment plan.
