Which is Better, Laser or IPL?

The results achieved by laser and IPL epilation are generally considered 'interchangeable', meaning about equal. However, each procedure has distinct advantages. Laser Epilation can also shave the skin while simultaneously treating the follicle below, whereas IPL cannot.
Intense Pulsed Light has the ability to treat large areas in less time (due to the total overall energy being used). In terms of 'progressive permanency', they both will typically produce an 80 to 90% reduction in ananagen hair growth activity within 90 days. Treatments should not be administered more than once per 14 day period (or twice a month).
