Hi! Thanks for the question! Microneedling can help reduce the appearance of sun spots and sun damage. It would require multiple treatments and follow up maintenance. We find that using treatments like BBL/IPL, Laser Resurfacing and Chemical Peels work best for more immediate results. I would recommend consulting with a practitioner in your area to see what would work best for you. Best wishes!
Sun spots can be improved with microneedling but in our practice we treat acne scaring, pore size, and skin texture with microneedling. Sun spots need to be treated with BBL, Halo, or Chemical peels. Best of luck to you.
