While it is easy to think of lasers as a single type of treatment, light therapy is, in fact, a rather broad topic, even when only considering dermatologic applications. There are not only several manufacturers of laser devices, but lasers that emit different wavelengths are used for drastically different indications. There are also many similar technologies that are commonly referred to as “laser treatment” although they technically are not, such as, intense pulsed light and radiofrequency treatments.
SkinDC offers cosmetic lasers for treatments including:
While the specifics of each treatment may differ slightly, most cosmetic laser treatments work based on selective heating. Since true lasers use a focused beam of light, a specific tissue particle may be targeted, while surrounding tissue is comparatively unaffected. For example, with laser hair removal, the laser is tuned to a particular wavelength to target the pigment in hair follicles. During treatment, follicles absorb laser light to the point that they are damaged and can no longer grow hair. Meanwhile, the skin surrounding the follicle absorbs little to none of the laser’s energy, and therefore avoids heating to the point of damage. Similarly, skin rejuvenating laser treatments target the deep dermis, heating collagen to its coagulation point. The body perceives this as an injury. Old collagen is flushed from the system and new collagen production begins. This can reduce or clear dark spots, reduce the appearance of lines and wrinkles, and clear away surface blood vessels.
Yes. Lasers are non-invasive, penetrating the skin without incisions. There can be a few mild side effects such as redness, swelling, and minor pain similar to mild sunburn after treatment. As the treatment area heals, sun protection is very important due to increased sensitivity, but complications are extremely rare.
