These are frequently due to increased melanin production associated with inflammation.
Freckles are usually related to sun exposure and genetic predisposition. Age and sun spots are the result of sun exposure and skin changes related to ageing and genetics.
Our StarWalker PQX laser is exceptionally effective in removing age and sun spots. In most cases it may take 1-3 treatments, depending on how dark and how many spots you have. Right after treatment, the spots turn a bit darker, may build a thin scab and finally fade away in 3-4 weeks. The treatment is similar for freckles. Treatment takes 20 minutes and there is minimal downtime.
