While Careprost is primarily used for promoting eyelash growth, it can also be used off-label to enhance the growth and thickness of eyebrows. The active ingredient in Careprost Eyebrows, bimatoprost, helps stimulate hair follicles and prolong the growth phase of the hair cycle. To use Careprost for eyebrows, it is important to follow the instructions provided by your healthcare professional or the product packaging. Typically, a small amount of Careprost is applied to the base of the eyebrows using a clean applicator brush or a sterile cotton swab. It is important to avoid getting the solution into the eyes.
