Real Stories From Recent Customers


Love this lash serum

The best lash conditioner. Don't bother trying any other, they are not as good as Tonik. 



Having used this serum for a number of months, words cannot explain how GOOD this product is. WOW!!! I started applying everyday for 1 month, then every other day and my eyelashes still touch my sunglasses!



It really does work! I've been using it for a few weeks now and I can see the difference. When I apply my mascara my friends ask me if I've had my lashes 'done' ! Love it!
