Lasers are one of dermatologist’s indispensable tools for treating almost every skin-related problem. Dermatologists also use lasers to eliminate damaged cells on the skin’s surface to reveal a smoother and clearer skin underneath.


Different skin conditions call for different types of laser and the dermatologists at Lesprit Medical Clinic break down the various problems that each type of laser can treat, so an appropriate treatment match is applied. The following conditions can be treated using laser surgery:

  • Acne and acne scarring, general scarring from injury as well as stretch marks
  • Birthmarks, including port wine stains and cafe au lait birthmarks
  • Problems with de-colouration or discolouration – age spots, vitiligo, hyperpigmentation, psoriasis, skin redness and tattoos
  • Skin cancer: lasers are combined with a cream or injected drug that kills cancer cells when the laser is used at the tumour site
  • Wrinkles, sagging skin and crows feet
  • Vascular problems including leg veins, thread veins, facial redness, angiomas, haemangiomas and telangiectasia
  • Unwanted excess hair
  • Warts and seborrhoeic keratoses


Numerous types of laser are used in skin surgery, firstly, ablative lasers that either cut into the skin or vaporise only the surface layer of the skin along with any surface blemishes and secondly, non-ablative lasers that penetrate into the skin without damaging the skin tissue.

Sources for the laser beam differentiate lasers by type and by the conditions they can treat. For example, green-wavelength KTP laser (potassium titanyl phosphate) lasers are used to treat both vascular and pigmented lesions, while Nd Yag lasers are used for skin rejuvenation, tattoo removal and hair removal for darker skins. Laser surgery for skin cancer normally uses a carbon or erbium YAG laser. Other laser sources include diode, Alexandrite and organic dyes. Lasers also vary in the way the laser beam is delivered. For example, Q-switched lasers release energy in very short, intense pulses, which cause less heating in the surrounding tissue carrying much lower risk of scarring. Lasers may also be categorised as single beam or fractional, where the laser light that is split into tiny fractions, in a pixel or net-like pattern that leaves tiny dotted areas of untouched skin, making the healing process faster and with minimal downtime
