Lasers are generally considered to be monochromatic. The word monochromatic derives from mono, meaning one/single, and chromo refers to light. So that indicates that a given laser usually emits only a single kind of light with only one wavelength/color or light.

Lasers work well in cosmetic applications through a unique process named “selective photo thermolysis.” When broken down into its parts, this term gives a very fancy meaning as photo refers to the frequency of light modulation and thermo indicates the production of heat in a specific region of the body and correspond lysis means to break down.

Thus, we can say that in the entire laser treatment, the wavelength of the light beam falling on a specified region must be in sync with the color of the targeted area, which needs to be addressed. Whether you have unsightly broken red capillaries, dark brown spots or freckles, or some other kind of undesirable skin condition and uneven skin toning, you can cure all such problems with laser treatment.
