Getting a sun tan on your hands is very common and completely reversible, as your skin naturally renews itself. To restore your natural skin colour, apply a broad-spectrum sunscreen with SPF 30 or higher daily to prevent further tanning. For treatment, look for over-the-counter creams containing active ingredients like vitamin C, niacinamide, kojic acid, glycolic acid, or liquorice extract, which gently exfoliate and fade pigmentation. For faster results, a dermatologist can suggest mild chemical peels. Keep your hands well-moisturised and avoid harsh scrubbing, as irritation can actually worsen darkening. With consistent care, your natural skin tone will gradually return.
