Freezing assistance plays the following roles in laser hair removal:
Anesthetic effect: The use of cryo-assisted laser hair removal can provide a local anesthetic effect, reducing or eliminating the patient’s discomfort or pain. Freezing numbs the skin surface and hair follicle areas, making the laser treatment more comfortable for the patient.
Protect the skin: During laser hair removal, the laser energy will be absorbed by the melanin in the hair follicles and converted into heat energy to destroy the hair follicles. However, this heat energy may also cause thermal damage to surrounding skin tissue. Freezing assistance reduces the thermal damage of laser energy to the skin by lowering the skin temperature and protecting the skin tissue from unnecessary damage.
Improve laser energy absorption: Freezing assistance can shrink the blood vessels around the hair follicles and reduce blood flow, thereby lowering the temperature of the skin. This cooling effect helps reduce the melanin content in the skin, making the laser energy more easily absorbed by the hair follicles, improving hair removal results.
Improved efficiency and comfort: By cooling the skin, cryo-assist can reduce side effects such as discomfort, burning, and redness during laser hair removal. At the same time, freezing assistance can also make the laser energy more concentrated on the target hair follicles, improving treatment efficiency and accuracy.
