The Cosmetic Laser's Role in Aesthetic & Cosmetic DermatologyMedical lasers have become very common in the practice Of Dermatology, Surgery, Plastic Surgery, Dentistry, Ophthalmics and Aesthetics or Cosmetic Procedures.
Light Amplification by Stimulated Emission of Radiation (LASER) produces an intense beam of light of an exact and narrow wavelength, with insignificant dispersion over a short distance. This property is utilized in dermatology to treat various skin disorders.
Cosmetic Lasers, and Their Treatment of the Following Skin Conditions.
- Port Wine Stains can be removed with the Pulsed Dye Laser (Vasculite) and Carbon Dioxide Laser. They require multiple sittings, but the results are very satisfying.
- Spider Nevi can be treated with the Pulsed Dye Laser and Long Pulsed Nd-YAG Laser. Lesions on the face can be treated with the KTP laser.
- Warts, a viral infection caused by Human Papiloma virus are effectively removed by the Carbon Dioxide or Pulsed Dye Laser.
- Scars such as acne scars or ice pick scars are resurfaced with the Erbium YAG laser or Carbon Dioxide Laser. Hypertrophic scars are flattened with the Pulsed Dye Laser.
- Moles and Nevi are removed for medical or cosmetic reasons using the Carbon Dioxide, Ruby or Erbium YAG Laser depending on the type. Pulsed Dye Lasers are also used to treat "Giant Pigmented Nevi.".
- Lentigenes (age spots) are removed using Ruby Lasers.
- Hair Removal temporary or long term has become a much easier task with the advent of lasers. Largely, laser hair removal gives excellent results in fair skinned people. Listed below are a few lasers used for hair removal.
- Medilite (Q switched YAG)
- GentLASE (long pulsed Alexandrite laser) preferred for dark hair in light skinned.
- Lyra (long pulsed YAG) for dark skinned people.
- Resurfacing is done effectively using lasers for acne scars, pits and small pox scars. Wrinkles are also treated by this technique. This procedure involves the precise removal of very thin layers of irregular skin. Carbon Dioxide Lasers and Erbium YAG Lasers are used for laser ablation. Q - Switched Nd YAG lasers are used for non-ablative resurfacing.
- Tattoo Removal - Tattoos are difficult to treat. Q-Switched Ruby Lasers and Nd YAG Lasers are effective. Multiple sessions over many months may be required to obtain favourable results. The colour of the tattoo and the depth of the pigment influence the duration and the outcome of the laser treatment.
