This is education, not advice
The information here is written for the general reader and does not replace a personal medical consultation. It cannot tell you whether your change is descent, volume loss or skin quality, how your skin would respond to being heated, or whether either option is appropriate for your face and your health.
No outcome is guaranteed
Neither option can be guaranteed. How much the face changes, how a scar settles, how long an effect is observed to hold and how skin responds to heat vary between individuals, and no number of years should be promised for either. A result is judged honestly only after the face has had months to settle.
Scars and irreversibility
A facelift leaves permanent scars that mature and soften over time but do not disappear, and the operation cannot be undone; what exists afterwards is revision, which is a further operation with its own cost and recovery. No cream, dressing or device removes a scar, and anyone describing a scar treatment as though it did is describing something else.
The risks are real for both
Both options can be followed by asymmetry, a result that is acceptable but not the one imagined, and a need for further treatment. Beyond that, the risks are different in kind: bleeding that collects under the skin, infection and nerve injury on the surgical side; burns, pigment change and fat loss under the treated skin on the device side. Each has its own warning signs, and the recurring risks and the signs that mean seeking care are listed at the foot of every guide on this site.
