Removal of tissue and inducing a thermal injury that heals by epidermal regeneration is achieved by which type of system?

Ablative systems are specifically designed to remove tissue and induce a thermal injury that promotes healing through epidermal regeneration. These systems work by delivering energy that effectively vaporizes the superficial layers of the skin, leading to controlled damage. This process stimulates the body's natural healing response, encouraging the regeneration of new, healthy skin cells.

The healing that follows is characterized by the growth of new epidermal tissue, which can lead to improved skin texture and tone. Ablative lasers are often utilized in various dermatological and cosmetic procedures, such as laser resurfacing, to address concerns such as wrinkles, scars, and other skin imperfections.

In contrast, non-ablative systems do not remove layers of skin but rather target deeper layers while leaving the surface intact. This typically results in less downtime and discomfort but may not achieve the same level of regeneration in the epidermis as ablative systems. Diode lasers primarily have applications for hair removal and treating vascular lesions and do not focus on tissue removal in the same way. Intense pulsed light (IPL) systems work differently by using broad-spectrum light, which is more suited for skin rejuvenation and pigmentation issues, without inducing the same type of thermal injury that leads to epidermal regeneration.
