Our NEW Clinically Proven Lash Serum is enriched with a lash-caring complex of nourishing ingredients including Castor Oil, Vitamin B5, filoxane and Hyaluronic Acid to help strengthen lashes over time and repair damage from excessive mascara and false lash usage. Castor Oil boosts hair, eyelash and eyebrow growth. Apply in the morning and overnight. Castor oil can be used to nourish our scalps and condition hair to leave us with thicker-looking, nourished lashes. Hyaluronic acid is a natural agent found in the epidermis layer of the skin. It plays a vital role in preserving the skins tone and elasticity, but also maintaining hydration. The narrow lash serum brush point allows for precise application to prevent any irritation to the eyes. The brush is made from hundreds to ultra-soft, densely-packed synthetic hairs. This allows them to completely cover every eyelash in the lash serum serum formula, from root to tip. To use New Clinically Proven Lash Serum, twist the end of the pen to release serum in to the brush fibres. One or two twists should be enough for the correct amount of serum. If too much is released, dab away any excess on a clean cloth or towel. Carefully run the brush along onto the upper and lower lash line, allow to dry for 60 seconds before applying mascara. For best results apply twice a day in the morning before mascara and at night after makeup removal.
