A key difference between IPL and BBL hair removal treatments is the number of wavelengths they use. In IPL, the laser beam use to remove hair, while BBL uses multiple wavelengths of light to target the melanin in hair follicles. Both treatments are relatively comfortable and are safe, with little to no downtime. They are relatively inexpensive, ranging from $400 to 600 per treatment. Ultimately, you will need to choose the one that works best for your needs. IPL uses light waves to target unwanted melanin and hemoglobin. It also encourages the body to produce collagen at the treatment site, which helps keep skin smooth and supple. Both types of treatments are safe for skin that exposed to sunlight. Several types of skin damage can treat with IPL, including acne scars, age spots, redness, and dilated blood vessels.
