What is Coolaser?
It’s an ablative laser treatment, which means that it removes the surface layers of skin while heating up water molecules in the lower layer, to trigger a healing response that boosts collagen and elastin production.
This in-office procedure takes about 15 minutes. Depending on the specific skin issues you’re targeting, you may need more than one session.
Awareness of Coolaser has increased as celebrities have raved about their results. However, the official Coolaser treatment is actually available only at the Beverly Hills, California, clinic of Dr. Simon Ourian.
There are many laser resurfacing options though, and even “many other lasers that do the exact same treatment,” says Dr. Harold Kaplan, a plastic surgeon in Torrance, California, in a RealSelf Q&A.

What happens during a Coolaser treatment?
At the time of your procedure, your provider will first apply a numbing cream to your skin. They may also give you a sedative to help you relax, and you’ll put on protective goggles.
Your provider will move the handheld Coolaser across the entire treatment area, zapping your skin as cool air blows. The cooling effect (and numbing cream) should reduce the burning or pain, but you’ll still feel like you’re being snapped with a rubber band.

How long does healing take?
Plan for a week of downtime, away from work and social activities, as you heal.
Immediately after your treatment, your skin will feel and look like it’s sunburned. Swelling and pain can last as long as a week, and your skin will peel during that time, shedding layers of damaged skin. Resist the urge to rub your face or pick at the peeling skin.
