Elevate your brow routine with the UKBROW Eyebrow Serum, designed to promote the look of fuller, thicker arches. A blend of biotin peptide and vitamin B5 helps condition and strengthen each strand, while myristoyl-pentapeptide-17 supports keratin production for visibly denser results. The formula is lightweight and easy to apply, gliding on and absorbing quickly. Over time, it encourages a bolder, more defined shape, helping thin, sparse, or over-plucked areas.
