Photorejuvenation technology is medically called IPL (intense pulsed light), also known as intense pulsed light, which is known as lunchtime beauty by beauty seekers because it is painless, simple and fast. 1.Why can photon play a cosmetic effect? The light source of photon uses the instrument to filter out the ultraviolet light that will tan the skin, and the light source with a wide spectrum (wavelength range: 560-1200 nm) uses its high-energy photon source to provide a stable energy output to radiate a broad spectrum of intense light to the deeper layers of the skin. Pigment particles and red blood in the skin absorb more photons and are stimulated to selective photothermolysis, which rearranges collagen and elastic fibers in the skin tissue, stimulates collagen proliferation and restores elasticity, resulting in new collagen, firmer skin, and skin rejuvenation, as well as enhanced vascular tissue function and improved circulation. These effects together make the facial skin wrinkle elimination or reduction, pore reduction. 2.How does lunchtime beauty treatment work? According to the principle of selective photothermal action, IPL can penetrate the epidermis and be absorbed by the pigment in the skin tissue in large quantities, which can cause the pigment mass and pigment cells to break up and decompose without destroying the normal skin. It is suitable for the treatment of structural changes including dermal and epidermal tissues involving changes in collagen tissue such as enlarged pores and visible changes in elastic fibers such as cobblestone spots and erythema. In terms of wrinkle improvement, IPL increases fibroblast activity through the accumulation of heat in the dermis, which is a proliferation of fibroblasts, resulting in the remodeling of collagen and elastin fibers within the stroma.
