What is IPL (Intense Pulsed Light)?
Add Time: 19/06/2019
IPL stands for Intense Pulsed Light. It is a light energy that is applied to certain parts of the body, so that the target structure - whether it be hair or blood vessel in the skin - absorbs the energy and is destroyed.
IPL is not the same as laser, although it is similar. The main difference is that laser (Light Amplification by the Stimulated Emission of Radiation) is a technique of producing light energy of only one wavelength. IPL (Intense Pulsed Light) uses white light which contains all the wavelengths of visible light from red to blue. However, to concentrate the treatments on different structures, filters are used to reduce certain wavelengths that are not needed.
The IPL beauty machine produces a sudden burst of light which is channeled down some fibreoptic tubes into a hand-piece. The hand-piece is held on the skin at the point where treatment is needed and light energy is transmitted to the skin. As this can get quite hot, the trained therapist uses a cooling gel on the skin. This is very soothing, helps cool the skin down, and also causes good contact for good light conduction.
How does IPL(Intense Pulse Light) work?
For hair removal: The light penetrates the tissue and is absorbed by the melanin in hair follicle, producing photothermal effect, conducting the energy from hair section to hair root, rising the temperature of follicle rapidly. The hair follicle is coagulated finally and the effect of hair reduction is reached.
For skin rejuvenation: Especial spectrum activates fibroblast to produce new collagen and elastic fibers, smoothing skin and returning elasticity to skin.
For acne treatment: The propionibacterium acnes (PAC) which causes the inflammatory reaction of skin, is a kind of anaerobic bacteria. Porphyrin consists in blood, which produces haemachrome after combing with Fe . It is a kind of photosensitive object . The special spectrum of PTF penetrates skin and absorbed by porphyrin, stimulates porphyrin to release monomorphism oxyanion which kills propionibacterium acnes effectively.
For sunburned pigmentation treatment: Pigment within focus group is denser than normal skin group's, so problem skin's heat energy after absorbing light energy is higher than normal skin's. especial spectrum selectively acts on focus group, lightening and eliminating pigment group while avoiding to cause harms to skin.
For superficial vascular treatment: Especial spectrum penetrates skin, and is absorbed by capillary vessels in tissues, which coagulates capillary vessels, decompose broken capillary.
