black spots on hands

Noticing new black spots on your hands, especially after sun exposure, can indeed be concerning. There are a few possible explanations for what you’re seeing. Firstly, it’s possible that these could be solar lentigines, commonly known as sun spots or age spots, which are caused by prolonged exposure to ultraviolet rays. Although they’re generally benign, monitoring them for any changes in size, color, or shape is crucial. Another possibility is post-inflammatory hyperpigmentation, which can occur after an irritation or mild trauma to the skin, though this typically happens in individuals with darker skin tones. It’s good that you’re paying attention to new skin changes—some spots, particularly irregular or rapidly changing ones, warrant a closer look. Melanoma, a type of skin cancer, can sometimes present as new dark spots and requires urgent evaluation, especially if you notice asymmetry, irregular borders, multiple colors, a diameter larger than 6mm, or if evolving over time. Dry patches usually feel rougher and improve with moisturization, so the persistency of the spots despite moisturizing indicates that they are likely due to pigmentation rather than dryness. I would advise scheduling an appointment with a dermatologist to get them checked professionally. Skin specialists can provide a proper examination and, if necessary, perform a biopsy to determine if the spots are harmless or require treatment. Your dermatologist might also use a dermatoscope, a tool that enables a more detailed look at the spot patterns, textures, and colors typically hidden to the naked eye. Until the appointment, ensure you use sun protection like sunscreen with a high SPF to prevent further UV damage. If there’s any itching, bleeding, or if new symptoms develop, seek medical advice promptly. This approach helps in ruling out serious conditions swiftly while addressing cosmetic concerns with informed professional guidance.
