Unlike other lash serums, our Lash Wizard does not contain the hormone ‘Kariprost’, which is used to increase blood flow, helping the lashes to grow. This hormone is harmful during pregnancy, so we do not include any in our lash serum, instead opting for more nourishing ingredients, such as Vitamin B, Keratin and Hyaluronic Acid. This makes our serum safer to use during pregnancy, but we always recommend consulting with a GP first before using any new products.
