Light radiation penetrates the skin, and the hair follicle, as the part with the most melanin deposition in the skin, absorbs the most light energy and converts it into heat energy, forming a higher temperature near the hair follicle. hair follicles, leading to inactivation of hair mother cells.
Step1: The xenon lamp of the epilator emits strong pulsed light.
Step2: The filter filters out harmful and useless wavelengths of light.
Step3: The effective light penetrates directly from the epidermis to the dermis.
Step4: The hair follicle melanin in the dermis absorbs light energy and generates heat.
The main factors affecting the effect of hair removal Energy Density Energy density = total energy / light port area
Individual Differences
1.There must be enough light energy converted into heat energy to achieve the effect of inhibiting hair growth
2.The energy used in beauty salons is usually around 10-20J/cm²,It can quickly destroy the hair follicles, but it will be more painful
and personal operation at home is risky.
3.According to clinical trials, the energy density of the home hair removal instrument is 4.5-5J/cm², which is a value that takes into
account both the effect and the pain.If it is too low, there is no effect for hair removal.
ndividual Differences
Skin tone:
The skin is darker and darker, and the epidermis will absorb light and cause fever or pain;
People with dark skin or dark skin are not suitable for hair removal using IPL hair removal device Hair depth:
Light-colored hair follicles have less melanin and absorb less light energy; people with very light hair are not suitable for hair removal using an IPL hair removal device; Hair density:
The thicker the hair, the more energy is needed to shrink it, so the energy density is greater and the frequency is more;
Note: Permanent hair removal: The clinical understanding is that the hair does not re-grow during a hair growth cycle, and many people understand that it is permanent for a lifetime.
Pain & Freezing Point Hair Removal Device
The stronger the energy, the more the skin absorbs, causing skin heat and pain. The way to eliminate the heat and pain of the skin is-cooling down, also called freezing point/ice sensation;
