Laser (including freezing point) and intense pulsed light (also known as photon, color light, E light, light quantum) are the commonly used permanent hair removal technologies, and their treatment principles, treatment process and treatment results are basically the same.
Is permanent hair removal possible?
The answer is yes.
1.Electrolysis method: this hair removal method is more painful and leads to a higher risk of infection and scar formation, and the speed of hair removal is slower, so it is rarely used now.
2, photon method: photon hair removal technology is the use of imported photon therapy instrument, according to different skin types and hair conditions, set reasonable treatment parameters (its large spot design up to 1 × 5cm), the use of 610 ~ 1000nm wavelength, so that the treatment is more uniform, hair removal speed is faster, with minimal discomfort to achieve the best hair removal effect.
3.Laser method: Compared with photon, laser hair removal is slower and needs to be combined with dynamic cooling system to protect epidermis from damage of laser beam.
The principle of photon hair removal
In hair, the content of melanin is much more than that of skin. This property determines that the hair will absorb more photon energy than the skin. Therefore, when the photons irradiate the skin tissue, the melanin-rich cells in the hair follicle will preempt the photon energy and convert it into thermal effect at the same time, resulting in irreversible damage to the hair-growing cells and follicles in the hair, while only minor reversible damage to the tissues surrounding the hair follicle is produced.
Who is suitable for hair removal?
Photorespiration has a wide range of indications, including both physiological and pathological hypertrichosis.
Who is not suitable for hair removal?
1.Pregnant women.
2.Patients with photosensitive skin diseases.
3.Those who cannot cooperate with the treatment.
4.People with brown skin after exposure to sunlight.
5.People who take antioxidants and photosensitive drugs.
Does photorespiration cause damage?
There is only a slight pain, like a rubber band flicking the skin and a slight heat sensation, and no anesthesia is generally needed. Photons only produce irreversible damage to the hair follicle tissue, and no or only minor reversible damage to normal human tissue. Very little allergy, even in sensitive skin, is caused by photons. Does not affect vision As long as you avoid looking directly into the beam, there is no effect on your vision. Also, the doctor will take certain protective measures when performing hair removal around the eyes. Occasional complications After photo hair removal, occasionally people develop blisters and hyperpigmentation, the former disappears in 1-2 weeks, the latter recovers within 6 months and scarring is rare.
Photorespiration cannot be done in one step?
In general, each area requires at least 3-5 treatments with an interval of 2 months between each treatment. This is because hair in the anagen phase has a higher melanin content and is more effective in hair removal. In contrast, during the degenerative and resting phases, the hair has a low melanin content and is less effective for hair removal. Since all hairs cannot be in the anagen phase at the same time, they need to be treated separately and “broken” individually.
How effective is hair removal?
The thicker the hair, the less the number of treatments, the better the hair removal effect. For example, hair in the armpits, hairline, calves and other parts of the body have a more satisfactory hair removal effect. Lip and forearm hairs are finer and softer, lighter in color, and the hair removal effect is poorer, but still permanent hair removal can be achieved after many repetitions. In general, hair removal can meet people’s aesthetic requirements. To achieve 100% hair removal, it is necessary to go through many treatments.
What should I pay attention to before and after hair removal?
Before photo hair removal, do not pluck or wax the hair, you can shave with a razor. After photo hair removal, you can bathe, make up and work normally, exposed parts should pay attention to sun protection and apply sunscreen (SPF≥15). Sensitive people are advised to eat less spicy and stimulating food in their diet.
