Patchy skin refers to areas of uneven colour or texture on the skin, often resulting from conditions like hyperpigmentation, dryness, or irritation. Treatment can vary depending on the cause but typically includes using gentle exfoliants to remove dead skin cells, applying hydrating moisturizers to improve texture, and using targeted treatments like brightening serums or prescription creams to address pigmentation issues. Consistent sun protection is also crucial to prevent further discolouration and maintain even skin tone.
