Fraxel or CO₂ - what’s actually the difference?
Although both treatments work fractionally, they create very different responses within the skin.
A 1540nm Fraxel laser is non-ablative. It delivers controlled columns of heat beneath the surface while leaving the outermost layer of skin intact. It can be a great option for concerns such as texture, pigmentation, fine lines and acne scarring, generally with less downtime.
Fractional CO₂ is ablative. It creates microscopic channels in the skin by removing controlled columns of tissue, producing a more intensive wound-healing and remodelling response. Depending on how it is performed, it can target deeper textural concerns, wrinkles and more established scarring but usually involves more downtime.
Neither is automatically “better.” The right choice depends on your skin, the concern being treated, the result you’re hoping to achieve and the recovery you can realistically commit to.
In tonight’s video, we break down how each laser works and why two people with a similar concern may still require completely different treatment plans.
