What Causes White Patches on Your Skin?
White patches on skin result from melanin loss or reduced pigment production in affected areas. Vitiligo, affecting 0.5-1% of the population, is the most common cause where immune cells attack melanocytes. Other causes include fungal infections like tinea versicolor, post-inflammatory hypopigmentation from eczema or injuries, and autoimmune conditions such as morphea or lichen sclerosus. Chemical exposure, certain medications, and genetic disorders like albinism can also create white patches. The patches may be small spots or large areas, and their appearance varies depending on the underlying condition and your natural skin tone.
