Aging is an ongoing process. The ultraviolet rays of the sun cause cutaneous changes such as damage to collagen, solar elastosis, telangiectasias, lentigines, and rhytid formation; the collective description of these negative effects is photodamage. Photorejuvenation is the process of using laser and light sources for returning skin to a more youthful appearance. This article explores the technology, clinical applications, side effects, and future directions of photorejuvenation with vascular lasers, pigmented lasers, and intense pulsed light sources.
衰老是一个持续的过程。太阳的紫外线会导致皮肤发生变化,如胶原蛋白损伤、日光性弹力纤维变性、毛细血管扩张、老年斑和皱纹形成;这些负面影响的总称是光损伤。光返龄是利用激光和光源使皮肤恢复年轻外观的过程。本文探讨了血管激光、色素激光和强脉冲光源的光返龄技术、临床应用、副作用和未来发展方向。
