CO2 laser resurfacing: what to know

One of the more powerful skin treatments available, with a recovery to match. Who it suits and what it asks of you.

Perspective from Stone Surgical Arts

CO2 laser resurfacing removes the outer layers of skin and heats the layers beneath, prompting remodelling as the skin heals. It produces substantial change and requires substantial recovery.

A thought to keep

The recovery is the part to plan for. Ask for the fully ablative timeline, not the fractional one, if that is what is proposed.

How it works

The laser removes the surface layer of skin while delivering heat to the dermis beneath. New skin forms over the treated area, and collagen remodelling continues for months afterwards.

Fractional treatments target columns of skin and leave untreated tissue between them, which shortens recovery at the cost of some intensity. Fully ablative treatment covers the whole surface and does the reverse.

What it treats

It is used for sun damage, uneven pigmentation, fine and deeper lines, and some scarring, particularly around the mouth and eyes where lines are difficult to address otherwise.

Like every resurfacing treatment, it works on the skin. It does not lift or reposition tissue, and a face with significant laxity will not be tightened by it.

The recovery

Expect redness, swelling, oozing and crusting in the first days, with the skin taking one to two weeks to re-epithelialise depending on depth. Redness can persist for weeks to months afterwards.

This needs planning around work and commitments. Diligent aftercare during that period is what determines the result and prevents complications.

Risks and selection

Pigmentation change, infection, prolonged redness and scarring are the recognised risks, and pigmentation risk is higher in darker skin types. A history of cold sores usually means antiviral treatment beforehand.

Strict sun avoidance and protection afterwards are essential. Ask who performs the treatment, at what settings, and how complications would be managed.
