What are White spots or unusual blemishes?

White spots or unusual blemishes on the skin can be caused by various factors, including fungal infections, vitiligo, or eczema. They may also result from sun exposure, which can lead to conditions like tinea versicolor or hypopigmentation. In some cases, these spots might indicate underlying health issues, so it's advisable to consult a healthcare professional for accurate diagnosis and treatment. Proper skincare and sun protection can help prevent some of these blemishes.
