I’m a sworn believer in skin rejuvenation by laser treatment.
There are many types of medical (Class 4) lasers– pigment lasers, ablative lasers, fractional lasers, vascular lasers. Each type is used to treat different medical conditions of the skin and most of them can effect some form of skin rejuvenation.
My personal favourite is the Q-switched ND:Yag laser, which was created to target pigmentation in the skin (my worst enemy!). I religiously do a laser photofacial at least once a month for maintenance of healthy even skin, on top of my usual skincare regime. 🙂
Lasers are very much operator dependent. Different doctors can achieve somewhat different end points on different schedules at different lengths of time.
Laser treatments are also patient dependent. Each prescription may vary, even if slightly, for different people according to the skin type, condition suffered and its severity, your risk appetite and expectations. (For this reason, it is quite hard to commoditize laser treatments and produce consistent results.)
One thing is for sure: laser skin treatment is effective, but you must consult with your aesthetic doctor before starting treatment to make sure you have your treatment tailored to your skin’s special needs. Otherwise, you may very well be wasting your time and money on something that doesn’t work!
