Clinical Application of LASER Techniques in Cosmetic Interventions: A Review

The advent of specific laser technologies has changed the face of cosmetic surgery in the new millennium with its minimally invasive, precise treatment options for skin rejuvenation, pigment and vascular abnormalities, hair removal and soft-tissue contouring. Progressions in wavelength manipulation, pulse modulation, and cooling technology have vastly enhanced the safety and efficacy of treatment for all skin types. Publications in the last years highlight the increasing contribution of lasers as complementary or alternative tools to conventional surgical and mechanical methods, with predictable results and shorter healing time. Laser-assisted treatments also show high satisfaction among patients, because they are very versatile and improve the tissue selective approach. Non-invasive body-contouring lasers have broadened the scope of clinical applications by producing a measurable reduction in fat without the use of anesthesia or downtime. Similarly, newer-generation skin resurfacing and rejuvenating laser systems promote collagen remodelling and sustained dermal amelioration. Although many questions still remain unanswered in the context of treatment parameter setting and risk minimization, further scientific evidence suggest lasers to be an indispensable tool in medical and cosmetic practice. In conclusion, laser technology continues to play a significant role in safe and effective cosmetic modifications.
