The energy wavelengths in a BroadBand light treatment can be adjusted for each patient's unique needs, so BBL is safe for all skin tones. To get your best results, we recommend you avoid UV (ultraviolet) light exposure (both natural sunlight and tanning beds ) for at least 10 – 14 days before your appointment. Tanned skin has higher levels of pigment (melanin), which can absorb the energy and impact your outcome. The treated areas will be extra sensitive to UV exposure, so you should not use tanning beds and limit sun exposure throughout your treatment and for a minimum of 10 – 14 days following your last appointment.
