KAISAR is the world’s first men’s healthcare device that uses Photobiomodulation therapy (PBMT), otherwise known as LED or light therapy. 

PMBT has proved to aid the development of sperm count, sperm motility and erectile function while seeing an increase in testosterone levels to improve fertility.

The human body has a variety of tissues that respond accordingly to the light rays irradiated across the electromagnetic spectrum. For example, the enzyme 8-Dehydrocholesterol in our skin absorbs 290-32 nm of ultraviolet rays from the sun to synthesize Vitamin D.

Photobiomodulation Therapy (PBMT) is a type of light therapy that utilizes the properties of cells that respond to light. In particular, red and near-infrared light stimulates the process of molecular production that has been proven to accelerate cell division and regeneration and improve blood circulation.

KAISAR helps to stimulate the production of Nitric Oxide (NO) and Calcium Ions (Ca2+) in the cells of male sexual organs. Nitric Oxide increases blood flow by expanding blood vessels and relaxing the muscles in the penis. When sufficient volumes of blood channel towards the penis, it becomes erect. With higher blood volume, erectile rigidity increases. While the use of Viagra or Cialis helps relax blood vessels, oral medication only provides a temporary solution for erectile dysfunction. 

KAISAR stimulates production of ATP and ROS in cells through light therapy. ATP is the essential energy source for tail movement in sperm, while ROS are the necessary molecules required to penetrate the cell membrane of the egg. Self-care with KAISAR can improve sperm quality and motility

KAISAR's emission of red light and NIR rays promote cell activity, helping to produce Leydig cells in the testicles. Leydig cells are organs that secrete male hormones (testosterone), and with higher number of Leydig cells increase, levels of testosterone also increase. Testosterone is key in improving sexual functions, but also in physical and mental vitality.

Universally, men want to be the best in bedroom activities for their partners, if not, satisfactory at the very least.

While solutions for improving the experience of sexual intercourse have long existed, there have been limited options available to treat potential underlying problems.

With visits to clinics and hospitals being somewhat taboo, KAISAR provides a solution to all existing shortcomings.

It’s easy to use at any time, anywhere. It’s safer than oral or invasive treatment, and you don’t have to pay a fortune every time you require treatment.

Unlike medications or injections that result in temporary changes, you can experience improvements gradually over time with consistent use.

For over 100 years, numerous scientficpapers have supported the hypothesis of specific light wavelength exposure increasing the number of reproductive sex cells, blood flow, hormone levels, sperm motility, and improving sperm quality.

CEO of KAISAR, Seokhee Kang has 8 years of product development experience in the technology of Flexible Electronics.

An early adopter of beauty products targeting wrinkles, PBMT soon became recognised amongst medical professionals for its attributions toward improvements to other internal processes of the human body.

Thousands of medical papers, professional consultations and clinical trials later, men's self-care device KAISAR, came to life in 2023.

Created under the guidance of university professors in South Korea, KAISAR’s PBMT technology helps men across the globe become better lovers, complete with confidence and energy with the dosage of just 15 minutes of daily self-care.
