Short summary

A laser database to monitor the effects of laser treatments, to compare the different laser systems and laser settings. We want to learn more about the importance of different skin types when treating with laser and the possible side effects.

Rationale

Light amplification by stimulated emission of radiation (Laser) is electromagnetic radiation, where there are different laser systems. Each laser type is characterized by a specific wavelength, whereas intense pulsed light (IPL) generate light with a spectrum of several specific wavelengths.

The skin's light absorbing tissue components are called chromophores and may be water, hemoglobin, melanin and tattoo particles. The chromophores absorb specific wavelengths and allow for controlled energy dissipation with selectively targeted heating of structures in the skin, also called selective photomolysis.

Lasers may be ablative or nonablative, depending on whether the tissue is evaporated or coagulated. 

Lasers have gradually become an important treatment within dermatology, ranging from vitiligo, hirsutism, vascular malformations, scars, warts and tattoos. When using laser, there is always a risk of side effects. It can be redness, pain, hypo -or hyperpigmentation, sore and scarring. It is therefore crucial that the clinician understands the principles of laser-tissue interactions.
