What permanently removes sun spots?
Sun spots (also called solar lentigines) can fade significantly with consistent sunscreen use, which prevents further UV stimulation of the pigment cells. For faster or more complete removal, options include topical ingredients like niacinamide and vitamin C, as well as professional treatments like chemical peels, laser therapy, and cryotherapy. Results vary based on depth and duration of the spots.
Sun spots form when UV exposure causes localised overproduction of melanin. The most important step in managing them is stopping further UV stimulation by wearing SPF 50 PA++++ daily. Without this, any treatment will be undermined by continued exposure. Topical ingredients like niacinamide, kojic acid, and tranexamic acid can reduce the appearance of spots over several weeks to months. Professional treatments work faster but should always be followed up with diligent sun protection to prevent recurrence.
