Collagen Lash & Lifting uses silicone rolls or pads instead of traditional rollers to give more of a lifting effect from the base of the eyelash. Superior formulation with conditioning and nourishing along with fast processing formulation and formaldehyde-free. Great for those with lighter color lashes (especially blondes!) - or anyone looking for a thicker "mascara" look (without having to wear mascara). A lash tint will make your lashes appear darker, thicker and longer and last for weeks.
