Laser skin rejuvenation, also known as IPL photorejuvenation or pulsed light skin rejuvenation, is a technology that uses high-energy pulsed light for cosmetic skin treatments. It effectively addresses various skin concerns such as texture improvement, pigmentation and enlarged pores. This technology works by having water molecules in the skin absorb the laser energy, causing a rapid increasing temperature in the treated area, which will damage the epidermis and a part of the dermis. The collagen fibers in the dermis are heated and contracted, and the fibroblasts are activated to synthesize new collagen, promoting epidermal regeneration and dermal remodeling. Moreover, when the temperature reaches 55-60 ° C, type 1 collagen fibers can quickly contracted to 1/3 of their original length, achieving the purposes of removing wrinkles and making the skin fuller.
1.Black doll treatment:
During the treatment, a layer of black carbon powder ia applied on the face. With the strong light absorption capacity of the carbon powder and the selective photothermal effect, it effectively removes the dirt and dead skin cells as the carbon powder blasts, achieving the effects of removing blackheads and whitening the skin. At the same time, it also stimulates collagen in the dermis, making the skin tighter and restoring elasticity.
2.White doll treatment:
Special light beams are used to generate high-energy heat through the irradiation of specific media, which is then transmitted to the dermis of the skin to stimulate the renewal and vitality of skin cells. This process helps to restore collagen and elastic fibers, thereby achieving multiple beauty effects such as removing wrinkles, whitening the skin, and shrinking pores.
3.Photorejuvenation:
Using millisecond-level wide-spectrum light to penetrate the epidermis, the energy is absorbed by the skin’s pigment groups in large quantities, causing the blood vessels to congeal and the pigment groups to break down, thereby achieving skin rejuvenation effects such as removing pigmentation and dilated capillaries.
