What laser is better for removal of nevus sebaceous - CO2 or erbium ?

Question

I had gone through CO2 fractional resurfacing and don't see any visible result in 1 month after it. Instead, the period of redness (erythema) lasted for 3 weeks. Is CO2 really effective when you need to deal with top layers of skin, for example remove nevus. I understand it's more effective for wrinkles and restoring collagen in deeper layers of skin since it has deeper impact (longer wave). But if we want to remove nevus and do it with less number of laser sessions, will Erbium be better ?

Naevus sebaceous, and other organoid naevi, are deep birthmarks that are often not removed very effectively by laser.  Ablative lasers may be suitable for smaller lesions, but treating larger lesions will often scar if treated adequately, or recur if treated gently.  I generally treat these surgically, and then follow up with laser to revise and fine-tune the surgical scar.  Best wishes, Shobhan.

A picture will be good. I usually perform fully ablative lasers rather than multiple fractional laser sessions. Depending on the depth and skin type, I choose either a CO2 or erbium, I usually complete the session with a light fractional CO2. One treatment, should give a good result.
