How do hair lasers remove unwanted hair?
The light energy of the laser is absorbed into the hair shaft and causes the temperature in the hair follicle to rise to a level that destroys the follicle and prevents regrowth.
How many hair laser treatments are necessary?
Due to the cyclic nature of hair growth, effective treatments only occur in the hair’s active growth phase; therefore several treatments (about 4 to 6) are necessary.
Is hair laser treatment permanent?
It is a permanent reduction – there is a 70 to 90% reduction of hair after approximately six sessions.
How does fractional laser work?
The fractional laser passes down to the dermis and creates thousands of tiny, microscopic areas of thermal damage that stimulate new collagen production and the replacement of damaged skin surface with new epidermal skin.
How many treatments are necessary with fractional lasers to treat acne scarring or wrinkles?
- With Erbium-type fractional lasers (non-blative) up to five treatments are normally necessary with 3-5 days of downtime after every treatment.
- With the deeper CO2 fractional laser (ablative), 1 or 2 treatments may be necessary with 5-7 days of downtime after every treatment.
