Why intense pulsed light hair removal needs multiple

There

hair growth phase, catagen, and stationary phase. Growing wool rapid cell division, during which most of melanocytes, and therefore very sensitive to bright light; in catagen, hair quality degradation, dermal papilla atrophy; quiescent isolated follicles and dermal papilla, hair loss. Different parts of the hair follicle growth cycle is different.

hair growth cycle and hair removal treatment of the relationship: 1. Because the light of catagen, quiescent hair no effect, so the hair into the growth phase only after the light to work, so the photon hair removal requires multiple treatment effect was obvious. 2. If a part of the small proportion of hair in the growing season, the number of treatment need to increase, whereas treatment times can be reduced. 3. Based on different parts have different hair growth cycle, the interval between each treatment was also different. Such as the beard, hair on upper lip area has a relatively short quiescent interval of time can be shortened to 1 month; trunk and limbs resting hair relatively long treatment interval of 2 months or so. 4, the depth of hair follicles varies by area, if the depth of deeper, longer wavelength lasers to be used for treatment. 5, as a part of the hair follicle density, the treatment should be appropriate to reduce the light energy.

under normal circumstances may have mild burning sensation after surgery, usually 2-3 hours to disappear. Part of a local minor swelling, usually 2-3 days to recover. Postoperative treatment area should be kept clean to avoid sunlight.
