Our Philosophy

Spotlight on the ingredients

Sugar cane

We extract the ingredient ethyl acetate from cane sugar, which forms the basis of the polish and gives it its liquid texture. 


We extract the ingredient butyl acetate from cassava, which forms the basis of the polish and gives it its liquid texture.


We get the ingredient nitrocellulose from cotton, which helps the polish form a solid film on the nail.


The ingredient acetyl tributyl citrate is extracted from corn. It helps the polish create its smooth, shiny coat on the nail.


Ginseng extract (panax ginseng root extract) tones the nail and restores its natural strength.


Lemon extract (citrus limon fruit extract) is packed with vitamins to boost your nails' health.


Vitamin-rich natural grape extract (vitis vinifera fruit extract) revitalises and cares for your nails.

Aloe vera

Aloe vera extract (aloe barbadensis leaf extract) protects the nail's structure and promotes blood circulation for strong, healthy nails.
