Nd Yag laser is a solid-state laser that makes use of a Nd Yag crystal as its laser medium to emit a longer wavelength laser that can deeply penetrate tissues. Its ultra-high power laser will cause thermal damage to target cells when the chromophores absorb the energy, expand rapidly, and burst. These dead cells will then be swept away by macrophages and excreted out of the body by the lymphatic system.
A CO2 laser is a high energy fractional laser that emits specific wavelength laser beams to penetrate the epidermis and dermis, causing microscopic thermal damage to destroy diseased cells. CO2 lasers can stimulate the growth of collagen, aiding in the development of younger, smoother skin to replace the damaged skin.
A diode laser is a solid-state laser produced by semiconductors to emit different wavelengths of lasers which are highly efficient due to minimal energy loss during generation. Diode lasers work on the principle of selective photothermolysis (SPTL) to target specific chromophores in the skin, such as melanin or blood. It destroys the chromophores by selectively heating them without injuring surrounding tissues.
Intense pulsed light(IPL) is a continuous, broad wavelength，noncoherent light usually in the 500 to 1200nm range which can produce concentrated high heat. It works based on the selective photothermolysis principle to treat different symptoms. The wavelength of each pulse of light can be different, so IPL is very versatile and is suitable for various skin treatments.
RF(radio frequency) is an electromagnetic wave that changes over 10,000 times per second. RF in different electromagnetic wave bands results in different levels of stimulation to the patient’s skin. It uses radio frequencies to heat the tissue and stimulate the creation of collagen and elastin to induce the tissue to rejuvenate the skin.
HIFU or high intensity focused ultrasound is type of energy directed to treat the tissues of the superficial musculoaponeurotic system without cutting open the epidermis. The temperatures of the focal point can rise to 60℃-75℃ causing cellular damage and stimulating the production of new viscoelastic collagen and elastin to tighten the skin.
Photodynamic Therapy (PDT), also called photochemical therapy involves three elements: oxygen, a photosensitizer, and light source. Firstly, a photosensitizer is applied and then activated by light of the appropriate wavelength and intensity. The activated photosensitizer will react with oxygen, resulting in a complex interplay of amino acid, fatty acid, nucleic acid, and create cytotoxicity to destroy the target tissue, which will ultimately result in lesion ablation while sparing the normal tissue.
Triglycerides are the most common type of fat in the human body, and they can be turned into solids at 5℃. Cryolipolysis applies low temperature on top of a target fat area to reduce the fat layer, it turns the triglycerides into a solid shape and speeds up the aging of adipocytes, then the dead fat cells will be gradually dissolved and removed by the body’s normal metabolism.
Diamond microdermabrasion can abrade dead skin cells and dirt like a “sand papering” ，and then vacuums away exfoliated particles by the same wand. This procedure also stimulates a remodeling process of the dermis that results in smoother, more elastic and healthier skin. Diamond microdermabrasion does not produce high-speed particles flows, so it is safe to use on areas close to the eyes and lips.
