Introduction
Regarding pigmentation removal, the first step is to determine the specific type of pigmented lesion. Although these spots appear as brown pigment deposits on the skin, a more detailed classification distinguishes them as epidermal pigmentation, dermal pigmentation, mixed epidermal-dermal pigmentation, and even post-inflammatory hyperpigmentation. Treatment approaches vary depending on the anatomical location of the pigmentation.
Sometimes, skin develops spots or pigmented lesions—not only impairing one’s personal appearance but potentially triggering appearance-related anxiety. So, how can these spots be effectively removed?
How to Remove Skin Spots
Addressing hyperpigmentation begins with identifying the specific type of spot. Although all appear as brownish pigment deposits on the skin, they differ significantly in anatomical location and histological origin: epidermal melasma, dermal melasma, mixed epidermal-dermal melasma, and post-inflammatory hyperpigmentation. Treatment strategies vary accordingly based on the depth and nature of pigment deposition. For epidermal pigmentation—such as freckles or solar lentigines—carbon dioxide (CO₂) lasers, 532-nm Q-switched lasers, or intense pulsed light (IPL) therapy are commonly employed.
Dermal pigmentation—including nevus of Ota, café-au-lait macules, and melasma—requires more time and multiple treatment sessions. Nevus of Ota and café-au-lait macules may respond well to 1064-nm or 755-nm Q-switched lasers. Melasma, however, necessitates a multimodal approach: systemic medications combined with topical depigmenting agents (e.g., hydroquinone, tranexamic acid, or retinoids), followed by adjunctive therapies—such as laser treatments, nano-microinjections, or chemical peels (e.g., glycolic or salicylic acid)—once melanocyte activity has stabilized.
Given its complex pathogenesis, melasma demands comprehensive, individualized management. Therefore, before selecting an appropriate treatment, it is essential to determine the underlying cause of the pigmentation. Moreover, individuals noticing new or changing pigmented lesions should promptly consult a dermatologist for professional evaluation and evidence-based management. We hope this information proves helpful!
