REVOX B77 Depilstop Hair Growth Inhibitor Serum is an advanced post-hair-removal treatment designed to slow and reduce hair regrowth over time. Powered by Kelisof™ technology, it targets hair follicles after shaving, waxing, or epilation to help weaken regrowth at the source. Suitable for use on both face and body, the lightweight serum works progressively with consistent application, delivering cumulative results rather than temporary masking. With regular use after each hair-removal session, hair grows back finer, sparser, and more slowly, helping extend smooth, hair-free skin for longer periods.
