Spots or patches on the skin can happen due to many different reasons, and the exact cause often depends on their colour, size, location, and whether they are itchy, painful, dry, or spreading. Common causes include fungal infections, allergies, eczema, pigmentation changes, sun exposure, acne marks, vitamin deficiencies, or certain skin conditions such as psoriasis or vitiligo. Some patches may appear red and itchy, while others may be dark, light-colored, dry, or scaly. Because many skin problems can look similar, it is important not to apply random creams, especially steroid-containing creams, without proper advice, as they can sometimes worsen the condition or change the appearance of the rash temporarily. Keep the skin clean, avoid scratching, use mild soaps, and apply a simple moisturiser if the skin feels dry or irritated. If the spots are spreading, changing colour, becoming painful, causing itching, or lasting for several weeks, it is best to consult a dermatologist for proper examination and diagnosis. A doctor may examine the skin closely and suggest creams, medicines, or tests depending on the exact cause. Early diagnosis and correct treatment usually help prevent the problem from worsening and improve healing.
