This is education, not advice
The information here is written for the general reader and does not replace a personal medical consultation. It cannot measure how deep your wrinkles are, tell you how your skin will heal, or say whether either laser is appropriate for you.
Neither laser is a default
Nothing on this site should be read as ranking one laser above the other, or as describing the shallower option as the cautious first step. Both are ablative, both carry pigment and healing risks, and the choice follows from the depth the problem needs rather than from a clinic’s equipment.
No outcome is guaranteed
No treatment can be guaranteed. How much a wrinkle improves, how evenly the skin heals back and how long the improvement lasts all vary between individuals. Resurfacing is not permanent, and the skin continues to age from wherever the treatment leaves it.
Pigment, infection and scarring
Treated skin can heal darker or lighter than it was, in either direction, and the risk is higher in darker skin and where healing skin is exposed to sun. Infection is a risk of any open wound, and a cold sore flare during healing can leave a scar. Redness that persists well beyond the expected weeks, or a surface that stays uneven, needs review rather than patience.
