Since the energy wavelengths in a BBL treatment can be adjusted for your unique needs, BBL is safe and effective on all skin tones and types. To get your best results, we suggest you avoid ultraviolet (UV) light exposure (both tanning beds and natural sunlight) for at least 10 – 14 days before your treatment. Tanned skin has an increased amount of pigment (melanin), which may absorb the BBL energy and impact your outcome. The treated areas will be especially sensitive to UV light, so you should continue to limit your sun exposure and not use tanning beds while you are getting BBL and for at least two weeks following your last treatment.
