Treatment of photodamaged and aging skin has changed dramatically during the past several decades. The therapeutic options included tretinoin, alpha-hydroxy acids, chemical peel, dermabrasion, laser therapy, and rhytidectomy.
  Among the above therapeutic options, carbon dioxide lasers have been extensively utilized in dermatology and plastic surgery. CO2 lasers has been used as a light scapel for incision or excision procedures, and as a volume ablation tool for removal of epidermis and superficial dermis.
  While continuous-wave carbon dioxide lasers have been able to successfully vaporize tissue for years, heat conduction to the surrounding skin with resulting scarring limited their use in cutaneous resurfacing. With the subsequent development of high energy, pulsed carbon dioxide lasers, clean ablation of the skin could be achieved without any significant heating of normal adjacent tissue. Thus the carbon dioxide laser has become an ideal tool for resurfacing rhytides, atrophic scars, and benign skin growth. Among the high-energy, pulsed carbon dioxide lasers, Trupulse laser has more high peak power and shorter pulse width I. e., 10,000 W and 60-120 μsec than other carbon dioxide lasers. Because Trupulse has more high peak power with short pulses, it diminishes thermal conduction to adjacent tissue and may result less erythema and faster healing.
  Treatment of photodamaged and aging skin by Trupulse laser has distinctive advantages and effectiveness without major side effects.
