Which three times should photon hair removal be divided?

Speaking of photon hair removal, Dr. Luo looked very excited. She said that the current technology is particularly good. Photon hair removal is a major discovery in modern photothermal science. According to the principle of selective photothermal dynamics, through some reasonable parameters, let the light pass through the surface of the skin to the root hair follicle of the hair. The light energy is absorbed and transformed into heat energy that destroys the hair follicle tissue, so as to make the hair lose the regeneration ability without damaging the surrounding tissue.

Light will choose to “burn” hair follicles only

Photon hair removal works by acting on melanin in hair follicles. “People with white skin and black hair have the best hair removal effect,” Dr. Luo said.

Hair effect: reduce skin friction

Referring to the worry that most people think permanent hair removal will cause sweating, Dr. Luo pointed out that it won’t at all. Dr. Luo pointed to the three-dimensional anatomical map on the table and told reporters that there are many accessory structures under the human epidermis, including hair follicles, sebaceous glands, sweat glands, blood vessels and nerves. Sebaceous glands “hold” hair, as if people were embracing big trees. The hair follicle is below the sebaceous gland, which discharges sebum through the pores and plays a role in wetting. Because the light source of photon hair removal only works on hair follicles, even sebaceous glands will not be hurt, let alone sweat glands next to hair follicles. “Hair is just to protect the skin from damage caused by too much friction. It has two distinct functions from perspiration, so it will not affect normal perspiration at all.”

After shaving for a long time, the skin will turn black

The most commonly used hair removal methods for modern women are shaving, wax removal, tweezers, hair removal cream, etc. These methods can not achieve permanent depilation, but also because of long-term stimulation of hair, resulting in more dense hair. At the same time, hair follicles are easy to infect, and the skin will become rough and black.

Photon hair removal requires at least three times

Photon hair removal works through melanin acting on hair follicles, and hair follicle growth is divided into growth period, resting period and degenerative period. During the growth period, the hair follicle has the most melanin and the strongest absorption of the light emitted by the laser. The more melanin, the clearer, the higher the hit rate, and the greater the damage to the hair follicle. Therefore, generally speaking, depilation needs at least three times. The hair follicles should be “destroyed” by times.

Doctor’s reminder:

  1. Go to a regular hospital and select an experienced doctor for permanent hair removal.
  2. Try to avoid physiological period.
  3. Before depilation, do not depilate in any way.
  4. The skin shall not be exposed to the sun before depilation, such as seaside tourism.
  5. If there is redness and swelling after depilation, apply ice by yourself.
  6. You can take a bath on the day of hair removal, but you can’t use irritant products such as bath liquid and soap. You can take a bath the next day.
  7. Pay attention to sunscreen after depilation.


Miss Tang is very busy recently because she has been doing photon hair removal for nearly two months and has been volunteering to publicize this project. Even friends of friends have to call in person to ask photon hair removal. Does it hurt? What feeling? How about now?

Miss Tang told reporters, “I am particularly afraid of pain, so I have no ears. So I am more worried about whether or not the hair will hurt. You think, the skin under the armpit should be very tender. It hurts when I lose my hair. But in order to be beautiful, I decided to try it once.” Tang Yue said that she was very nervous when she was lying on the beauty bed of the hospital. Then began to depilate. “Maybe I’m too nervous. I really feel pain when I take off the right for the first time. I don’t feel much when I take off the right and the left. I think I’m too nervous to be so sensitive. In fact, the pain is acceptable.”

Miss Tang, who has depilated for nearly two months, said that at present, there is no hair under her armpits, so there is no need for a second time. On the night of the first depilation, there was no uncomfortable feeling under the armpit, and now the skin under the armpit is much smoother than before. The doctor said that this instrument can play the role of rejuvenating the skin.
