Photorejuvenation is a skin treatment that uses lasers, intense pulsed light, or photodynamic therapy to treat skin conditions and remove effects of photoaging such as wrinkles, spots, and textures. The process induces controlled wounds on the skin, prompting it to heal itself by creating new cells. This process reverses the signs of photoaging to a certain extent by removing appearances of damage. The technique was invented by Thomas L Roberts, III using CO2 lasers in the 1990s.〔Roberts, Thomas L III. The emerging role of the CO2 laser in aesthetic plastic surgery. Presented at the XIII Congress of the International Society for Aesthetic Plastic Surgery, New York, NY, Sept. 28-Oct. 1, 1995.〕 ==Skin rejuvenation== Skin rejuvenation can be achieved through various modalities including: thermal, chemical, mechanical, injection, and light.〔(【引用サイトリンク】title=Photo Rejuvenation for Better-Looking Skin: What Doctors Are Saying )〕 # Thermal rejuvenation using a radio-frequency device to induce a thermal effect in the skin. # Chemical rejuvenation with chemical peels. # Photo rejuvenation with light pulses from lasers or lamps. # Mechanical rejuvenation by dermabrasion or microneedling damage the outer layers to promote skin regrowth # Injections for rejuvenation with botox, fillers, collagen. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Photorejuvenation」の詳細全文を読む スポンサード リンク
