When is it worthwhile to repeat a CO2 laser?
I’m really glad you asked this because I’m seeing a lot of similar questions on the blog. The question really is………at what point will further treatments not confer any or much further benefit? Like many things, it’s a cost benefit analysis! More on CO2 lasers.
There are several ways to approach this. One is to know that with fractionated lasers you will be replacing about 10-15% of your skin with each treatment. So after 3 treatments, you’d have replaced about 30-45% which is definately enough to see a noticeable difference. It’s a little like aerating your lawn. The old, sun damaged microscopic “plugs” slough off, and new, fresh collagen grows in it’s place. At age 55, with large pores and acne scars, 1 treatment would generally not be enough to see much difference.
Another way to estimate is by age and the severity of the sun damage or acne scarring, etc. A person in their 30s with mild-moderate damage will need, on average about 1-3 treatments whereas a person in their 60s with moderate to severe damage might average 4-6 treatments for an excellent (but not perfect!) result.
Your dermatologist should be able to give you a realistic estimate!
