Hello, Dark spots on the legs are very common and are usually caused by sun exposure, irritation (like shaving or insect bites), or benign growths such as age spots or seborrheic keratoses. The exact treatment depends on what the spots are, so an in-person dermatology exam is important. In general, treatment options may include: Prescription lightening creams (such as hydroquinone, azelaic acid, or retinoids) to fade dark pigmentation over a few months Chemical peels to improve discoloration and skin texture Laser treatments, which are often very effective for stubborn dark or rough spots when done by an experienced dermatologist Cryotherapy or minor procedures if the spots are raised or rough Daily sun protection is essential, even on the legs, as sun exposure can worsen dark spots and cause them to return. In London, I recommend seeing a board-certified dermatologist at a reputable clinic, such as those on Harley Street, The London Clinic, or an NHS dermatology department (for example, Guy’s & St Thomas’ or King’s College Hospital). Look for providers experienced in treating pigmentation concerns, especially if you have darker skin tones. A dermatologist will be able to confirm the diagnosis and guide you toward the safest and most effective treatment plan for your skin.
