How it works
It all begins with a consultation. Your doctor looks closely at your skin, assesses your skin type, the degree of ageing or roughness on the surface, and what you would like to improve. This step matters, because there are many lasers with different strengths, and choosing the right one along with the right settings decides much of both your result and your recovery time. Your doctor also asks about your medication history, your sun exposure habits, how your skin tends to scar, and any skin treatments you have had before.
Before the session, the area is usually cleansed, and a numbing cream may be applied to the skin to keep you more comfortable. How much numbing you need depends on the type of laser, how deeply it works, and the size of the area being treated. Both you and the person treating you wear protective eyewear throughout, because laser light can harm the eyes.
During the treatment, your doctor moves the laser handpiece across the area being worked on. Depending on the laser, the beam either removes a very thin part of the surface layer or delivers heat into the layers below to prompt the skin to renew and make collagen. You may feel something like the light snap of an elastic band, along with a warm, tingling sensation on your skin. A session usually lasts around 20 to 60 minutes, depending on the area and the type of laser.
Laser rejuvenation usually needs a course of several sessions a few weeks apart, so your skin has time to recover in between. Some of the stronger lasers may need fewer sessions but a longer rest each time. After each session, your doctor assesses how your skin has responded and adjusts the plan for the next one. The exact number of sessions depends on the type of laser and the condition of your skin.
