|Short description Vaniqa cream contains the active ingredient eflornithine, which is a type of medicine known as an antiprotozoal. Eflornithine works by blocking the action of an enzyme called ornithine decarboxylase. This is an enzyme found in hair follicles and is needed for hair to grow. The cream is applied to the skin to reduce the growth of unwanted hair. It is used to treat unwanted facial hair growth in women, usually around the lips or under the chin. Eflornithine only slows down the growth of unwanted hair. It does not actually remove hair so another method for hair removal such as plucking or shaving may need to be continued whilst using Vaniqa cream. The benefit of using Vaniqa cream may be seen within two months after starting the treatment. If no improvement is seen after four months then treatment may be stopped by the doctor. Vaniqa cream needs to be used continually once the benefits of reduced hair growth on the face have been seen. If treatment is stopped then re-growth is likely to occur within two months.
