What is IPL?

Intense pulsed light (IPL) is a technology uses a high-powered, computer-controlled flash gun to deliver an intense, visible, broad-spectrum pulse of light, generally in the visible spectral range of 400 to 1200nm. Various cutoff filters are commonly used to selectively filter out shorter wavelengths, especially potentially damaging ultra violet light. The resulting light has a spectral range that targets specific structures and chromophores (e.g. melanin in hair, or oxyhemoglobin in blood vessels) that are heated to destruction and reabsorbed by the body. IPL hair removal is hot and more painful due to the shots being hot. IPL has 5 to 8 pulse for one flash. The energy of every pulse is different. The IPL pulse energy is diminishingduring treatment, there will be 3 pulse waveforms, replaced by the previous pulse energy, and then sequentially attenuated.

What is OPT?

OPT hair removal machine is upgrading from the IPL hair removal machine and cut or cancel the energy decease of the sub pulse.

OPT laser hair removal is short for Optimal Pulsed Technology, The basic theory for the Opt laser hair removal machine is the selective absorption of light. The melanin in the hair follicle will absorb the laser, and the laser will heat the hair follicles.

The temperature in the hair follicles increased fast in a short time. Then achieve a permanent hair removal.

What is SHR?

Super Hair Removal (SHR) is utilizes concentrated light beams to destroy the hair follicles. That means truly removing it from the root. Each pulse of light is an incredibly narrow, specific wave length of energy that is absorbed by the melanin in the hair follicle. The process gradually heats the melanin and hair follicles with effective heat buildup to destroy the hair for long-lasting results.


IPL treatment needs higher first pulse energy because of the sub-pulse energy decrease. Burning may happen because of the unequal pulse influence.


For the OPT, it does not burn or hurt at all. SHR technology has divided the pulse in every flash. One flash one pulse, every flash energy is the same.


OPT SHR machine uses the sweeping super hair removal method, the frequency could up to 10Hz. Basic IPL hair removal needs several seconds for the next shot.

The research proves SHR hair reduction mode is 2 to 3 times faster than the IPL method.

OPT SHR Method needs 4-6 sessions for permanent hair removal; IPL needs 6-12 sessions.


As we referred above, the pulse energy with OPT technology is the same, there is no energy diminishing. There is more energy delivered to the targeted areas. The OPT method has more effective and much faster results.


IPL hair removal needs several seconds for the next shot,so it costs more time.
