Nonablative Lasers: Shining a Light Beneath the Skin

Light is rarely in short supply in the Valley of the Sun. However, even Sonoran sunshine can’t compare to the skin-affecting capabilities of laser light energy. Med spas harness this energy and use it to perform a variety of skincare procedures. 

All lasers operate by emitting light of a single wavelength. By calibrating that wavelength, Phoenix laser hair-removal technicians can better target follicles without causing excessive damage to surrounding tissues. Read on to learn more about the technology behind this form of epilation.

What are the different kinds of lasers?

In the world of cosmetic laser procedures, there are two basic players: ablative and nonablative lasers. Ablative lasers use high temperatures to vaporize the top layers of skin and reveal the younger skin beneath, whereas nonablative lasers breeze through that top layer without harming it and instead heat the dermal tissue below.

Which kind offers the best laser hair-removal results?

Nonablative lasers work best for acne scars and discoloration, improving the appearance of fine lines only after several treatments. However, they are also the lasers of choice for hair-removal procedures. The heat that nonablative laser systems deliver to dermal tissues can target the follicles of unwanted stubble instead, preventing hairs from growing back over time.

Does laser hair removal hurt?

It varies from person to person. Technicians compare the sensation to a rubber band snapping against the skin. Fortunately, some lasers can minimize any discomfort. At Camelback Dermatology & Skin Surgery, the team utilizes a nonablative Cutera CoolGlide system, which cools the skin immediately after delivering each pulse of laser light energy.

What laser hair-removal side effects can I expect?

Nonablative lasers sidestep some of the drawbacks of ablative lasers, including recovery times that can last up to two weeks and side effects such as swelling and crusting. Hair-removal lasers do have side effects, however. Post-treatment tenderness and redness are both typical. Professionals recommend applying a cold compress to alleviate temporary discomfort.
