How much do you know about hair removal? Let’s take stock of all kinds of laser hair removal.
The following is the comparison of parameters of common laser hair removal methods:
Project: ruby laser
Wavelength: 694nm
Treatment times: 3 ~ 5 times
Degree of skin injury: high probability of skin trauma
Side effects: obvious side effects: easy to pigmentation and edema
Therapeutic effect: it only works on superficial hair follicles, and the depilation effect is not obvious
Project: long pulse width alexandrite laser
Wavelength: 755nm
Treatment times: 3 ~ 5 times
Degree of skin injury: high probability of skin trauma
Side effects: prone to side effects: epidermis (17%), cystitis (13%), pigmentation
Treatment effect: good hair removal effect
Project: Nd: YAG laser
Wavelength: 1064nm
Treatment times: 3 ~ 5 times
Degree of skin damage: the probability of skin trauma, and the required ability is 2 ~ 3 times that of semiconductor
Side effects: obvious side effects: erythema, bursitis, strong pain
Treatment effect: insufficient energy, unable to go deep into hair follicles, and the hair removal effect is general
Project: semiconductor laser
Wavelength: 808nm
Treatment times: 3 ~ 5 times
Degree of skin injury: the probability of skin trauma is very low
Side effects: the side effects are low, and only a few customers have reddish skin
Treatment effect: significant hair removal effect
Project: intense pulsed light (strictly speaking, it is not completely subordinate to laser, but the principle is similar)
Wavelength: 500 ~ 1200nm
Treatment times: 3 ~ 5 times
Degree of skin damage: low probability, which can cause slight damage to collagen and occasional pigmentation
Side effects: the side effects are low, and only a few customers have reddish skin
Treatment effect: significant hair removal effect, multiple wavelengths can treat a variety of skin diseases
Xiao Bian’s message: the four laser hair removal methods mentioned above have their own advantages. How to choose depends on everyone’s specific needs.
