About
Laser skin tightening is a minimally invasive procedure with little to no downtime.
It heats the skin, causing collagen to constrict, making skin look tighter, more firm, and less crepey.
It stimulates production of collagen and elastin in the skin.
Safety
Laser skin tightening is considered quite safe, and typically, no anesthesia is required.
Some swelling and redness is normal, and in rare cases there could be scarring or infection.
Convenience
Laser skin tightening requires minimal to no downtime so you can get back to your normal activities.
The procedure itself takes 30 to 90 minutes and should only ever be performed by a cosmetic dermatologist or a highly trained skincare professional.
