Enhance the look of your eyebrows with our brow-amplifying serum - the only brow booster product that supports the body's ability to anchor the hair follicle "bulb" to the elastin root system, delivering thicker and fuller looking brows. In a 12-week clinical evaluation, participants saw up to a 200% increase in eyebrow width, and up to a 97% increase in visible hair improvement. Results vary depending on gender, age, genetic predisposition, environmental conditions and more. Can be applied under makeup with little or no wait time.
