7 Misunderstandings About Laser Permanent Hair Removal-Beijing Zhenhuimei Beauty Equipment Co., Ltd.

Girls in the new era have experience in laser hair removal, but there are many misconceptions about permanent laser hair removal, the following 7 most common laser hair removal misunderstandings, which ones have you heard?

Misunderstanding (1) After laser hair removal, does the hair "permanently" not grow?
For example, the 755nm laser wavelength, which is optimal for Asian black hair, can reduce hair by about 20% per hair removal session*. During the course of treatment, the hair will gradually become thinner and thinner, and the definition of completing the laser permanent hair removal treatment is that the regrowth of black hair is difficult to see with the naked eye, and this effect will be maintained "permanently". However, the final hair removal effect will still vary from person to person. For example, a woman who is pregnant after completing the permanent hair removal treatment may cause black hair to regrow due to hormonal changes.

Misunderstanding (2) Is "permanent maintenance" necessary for laser hair removal?
As long as you follow the doctor's advice and receive the 755nm laser wavelength hair removal treatment, you should be able to achieve a thorough and effective hair removal effect within the expected time without permanent maintenance. Optical hair removal treatments that require "permanent maintenance" generally fall into the following three situations:

1. Hair removal with IPL
It is characterized by the use of 810nm wavelength, which can only slow down hair growth and make it younger, but cannot achieve the permanent hair removal effect of 755nm laser wavelength; therefore, permanent maintenance" is mostly included in the after-sales service of IPL hair removal.

2. Cool down with an ice pack
Laser hair removal needs cooling protection at the same time. Among the hair removal devices that use extra ice to cool down, TKS" is the representative, and the technology has been used for 19 years. However, using the old-fashioned ice cooling method not only prolongs the time of each treatment, but also greatly reduces the effect of the treatment because the temperature of the hair follicles receiving the laser is greatly reduced, resulting in the need for "permanent maintenance" to make up for technical loopholes.

3. Insufficient amount of refrigerant
Laser hair removal is a high-energy treatment, and the investment cost is expensive. Some beauty centers have launched affordable 755nm laser hair removal treatments, but in order to save costs, the amount of refrigerant used is much lower than the standard recommendation. When performing treatments in disguise, the laser energy must be lowered to reduce pain, which ultimately affects the hair removal effect, so they provide "permanent "Maintenance" to make up; what's more, the skin may be damaged due to insufficient cryoprotection. Features of this type of laser hair removal treatment: use the built-in freezing point hair removal device, but the hair removal price is relatively flat by 40-50%.
 
Misunderstanding (3) Is it necessary to apply ice and blow cold air to cool down for laser hair removal?
The scientific principle of laser hair removal is to kill the hair follicles with high heat and completely remove the hair. In order to avoid burning the skin, safety cooling equipment must be provided. Traditional cooling methods such as applying ice or blowing cold air will affect the heat transfer to the hair follicles, which will reduce or slow down the hair removal effect. Therefore, most hair removal devices break through the original market and continue to use ice to cool down, and introduce a unique intelligent cooling system, which releases the refrigerant 0.02 seconds before the laser is emitted, and freezes the epidermis in real time to protect the skin without affecting the heat received by the hair follicles at all. , so that the laser energy can completely eliminate hair follicles, achieving a truly safe, fast and effective hair removal effect.

Misunderstanding (4) Anyone is suitable for laser hair removal?
Most hair removal devices now contain a laser wavelength of 755nm handle head, which is mainly aimed at completely removing black or dark brown hair of Asians. The principle is that the higher the melanin in the hair, the more it can transmit the laser heat energy to the hair follicles to destroy and kill the hair, making the hair no longer grow. Therefore, it is not suitable for people with light brown, blonde, red or white hair. In addition to the 755nm laser wavelength, another laser wavelength of 1064nm claims to be able to rejuvenate the skin and is suitable for people with darker skin. However, since the energy is still far below 755nm, the hair removal effect is relatively weak, and the number of treatments required will be more.

Misunderstanding (5) The smaller the handle of laser hair removal, the more detailed and thorough it will be?
To remove hair meticulously, it depends on whether each hair follicle is covered by laser heat energy! The hair removal instrument is equipped with 12-24mm handles to meet the needs of different positions; the unique 24mm handle helps the laser energy to cover a deeper and wider range. For larger parts such as thighs, calves and back, use the 24mm handle to Leakage of hair follicles is minimized. Taking the calf removal treatment as an example, it can be completed in as little as 9 minutes, allowing guests to enjoy efficient and thorough hair removal.

Misunderstanding (6) Can laser hair removal be completed after 4-6 treatments?
According to the FDA report, using a 755nm laser hair removal device, 6 courses of treatment a year can completely remove hair. However, in the end, the hair removal effect will vary depending on the device model, freezing technology, and hair growth status. But the most important factor that determines whether the hair removal effect is thorough is the "freezing" technology!

Misunderstanding (7) Outdoor and water sports can be performed immediately after laser hair removal?
Since laser hair removal is a high-energy treatment, before and after hair removalYou should pay attention to the following items for one to two weeks: avoid sun exposure, high temperature and strenuous exercise. Such as bathing, sauna, hot yoga, swimming, etc. are not suitable

In addition, if the body has special conditions such as: taking photosensitive drugs, infected wounds, eczema, folliculitis, pigmentation, etc., in individual cases, you should first seek medical advice and conduct a scientific laser reaction assessment to ensure The physical condition is suitable for laser hair removal.
