IPL(Intense Pulsed light)
IPL is a technique that uses the light as pulses for treating. When treated over the hairy parts, the hairs absorb the light emitted and the absorbed light is converted to heat which in turn suppresses the growth of hair follicles and its melanin content.
DPL (Dynamic Pulsed Light)
DPL is an advanced method of IPL that uses the light ( wide range of the light spectrum) in a controlled intensity over the root of the hair to be removed or the hair follicles. The light is half a quotient absorbed by the pigments on the hair. This makes the hair root to absorb the light which is then converted into heat energy to destroy the pigments. Pigments are the main cause of hair growth in all areas. Apart from hair removing, DPL also used in the process of healing pigmentation and acne ( which occurs at all ages particularly for the teenagers now).
SHR (Super Hair Removal)
SHR is the newest technology which is one advanced form of DPL. In this technique, the light is emitted in many pulses but not a prolonged emission of light. Hence it is casual for people with sensitive fear.
Comparison between three
People who are darkly toned feel discomfort due to the heat from the device when they are compared to the whites. You can think of IPL as a black cloth absorbing all the heat but the white cloth which reflects or absorbs the heat at a reduced rate when compared to the latter. IPL is similar to flashlight sparkled out of the camera.
Even though DPL is an advanced form of IPL, it is effective and quick in hair removal when compared to IPL. It removes all the gentle and small hairs, but IPL is used to remove only coarse hairs first and then a small number of tiny hairs. Using IPL you have to make continuous exposure to the light which is somewhat time-consuming and painful too. But DPL, on the other hand, uses only pulses of light that to in a controlled manner which essentially treats the small hairs too.
IPL can be used only on specific skin tones and hair colors, if used adversely it has the issue of creating sunburns or making small holes in the skin. IPL cannot be used for dark skins, red, white and grey color hairs. That is the only advantage of DPL which treats all types of hairs.DPL has the ability to clean the pores and tightens the skin if it is aged.
SHR uses tender pulses of energy at a relatively higher repeated rate. This makes the skin gets heated gently. Only fifty percent of energy is reacted over pigments which are responsible for making the hair grow coarse and dark. The remaining fifty percent is used to treat the hair-growing papilla cells which are involved in the production of hair. Therefore each and every hair is targeted and removed properly. For new customers, SHR would be more suitable since it is painless when compared to IPL, but cost-wise SHR beats both IPL and DPL.
Moreover, the instrument is moved in a gentle motion over the body parts in SHR but in IPL it is kept idle in a place for some time and then moved.
