This is one of the most common misunderstandings about CO2 laser. Deka CO2 (and any ablative CO2) is excellent for what it actually does — resurfacing skin, smoothing fine wrinkles, improving tone and texture. But the nasolabial fold isn't primarily a skin problem. It's a soft tissue and structural issue. What creates the fold: The malar fat pad descends over the cheek with age, piling up just above the fold. The deep medial cheek loses volume, creating an apparent depression. Skin laxity adds to the depth but isn't the primary driver. What CO2 does well in this area: Improves fine wrinkling and crepiness on the fold itself. Tightens skin modestly (5 to 10 percent reduction in laxity for ablative CO2). Better tone, pigmentation, and quality. What CO2 doesn't do: Lift the descended cheek pad back up. Restore the volume that's been lost. Significantly reduce the depth of the fold. For meaningful fold improvement, the toolkit is different: Filler in the deep medial cheek or directly in the fold (HA, lasts 9 to 18 months). Deep plane facelift if you have moderate-to-significant facial descent (most durable answer). Fat grafting to cheek + fold for longer-lasting volume restoration. CO2 makes sense as an adjunct to any of these — done at the same time as a facelift, it adds skin quality on top of the structural lift. As a standalone, it disappoints patients hoping for fold reduction. Honest read: if your goal is genuinely softening the nasolabial fold, get a consultation that discusses volume and lifting first. CO2 can be the second layer once the structural plan is set.
