Laser surgery and freckles
Laser surgery maybe too drastic for freckles, I would suggest IPL or IPL and Fraxel (Pulse Fraxel). Laser surgery should be considered for patients with really severe sun damage- see video. All the best, DR Davin Lim Laser dermatologist ,Brisbane. Australia.
If you want to get rid of freckles, consider an Intense Pulsed light (IPL) treatment. May take one or 2 sessions but should work well.
