Lasers are a great way to resurface the skin and reduce scars. More specifically, there are two lasers that do this exceptionally well. The Erbium laser is a state-of-the-art laser that resurfaces the skin and reduce scars in under an hour. The results are almost instant, and only about 3-4 days of downtime are required.
Another option is the CO2 laser. The CO2 laser penetrates the skin deeper than the Erbium; therefore, the results are a little better, but you would need about 7-10 days of downtime. Also, because this laser is more invasive, you do not need multiple treatments like the Erbium.
A consultation with a board certified cosmetic plastic surgeon or a dermatologist would be the first step in treating your scars!
I would highly recommend a high quality pharmaceutical grade skin care routine that contains ingredients that have been developed to treat acne on the face.
Hope this helps!
