Pearl
Introduction
The Pearl procedure combines the impact of resurfacing lasers with the gentleness and safety of non-invasive procedures to treat aging and sun-damaged skin. Pearl, using YSGG-2790nm wavelength, delivers significant results in 1-2 treatments compared to the 4-6 treatments required with fractional non-ablative devices. YSGG-2790nm is novel wavelength designed to improve patient treatment experience and results.Water Absorption vs. Wavelength

| Er:YAG 2.94µm primarily vaporizes tissue due to its high water absorption. Heat is confined in the epidermis. No hemostasis. | CO2 10.6µm, the margin between a safe, repeatable ablation and overheating the dermis is narrow as evidenced with numerous cases of non-transient pigmentation changes. | The goal for our YSGG 2.79µm is to ablate and coagulate to a controllable depth of epidermis while depositing some heat into the dermis, promoting new collagen. |
