Eyelash enhancer made from ricin oil, also called castor oil. This oil provides numerous benefits to the skin, but it certainly stands out for its usefulness as a hair enhancer: it promotes eyelash growth and thickening by penetrating the hair follicles, making lashes (and even eyebrows) look stronger, thicker, thicker and healthier, as it strengthens, increases growth and adds volume, as well as preventing thinning and hair loss. How do you apply eyelash enhancer? On clean eyes, apply a layer of oil from the roots of the lashes to the tips. The ideal is to apply the eyelash enhancer twice a day: once in the morning and once in the evening, every day, for at least three months (visible results after the first month).
