The energy wavelengths used in a Forever Young BBL treatment can be customized to meet each patient's unique needs, making it safe and effective for all skin tones. To achieve the best results, we recommend avoiding unprotected UV (ultraviolet) light exposure, including tanning beds and direct sunlight, for at least two weeks before your treatment. After tanning, your skin has higher melanin levels, which could absorb the BBL energy and impact your results. Since the treated areas will be more sensitive to UV light, it's essential to continue limiting sun exposure for at least two weeks after your final session.
