Make up

We are experts in the tolerance and efficacy assessment of colour cosmetic products (make up, mascara, lip products). We assess their long lasting effect, cover and mattifying effect, the gloss effect of lipsticks and the efficacy of lip repair balm, among others.

Our studies of colour cosmetics are complemented by photographs (before and after), as well as an image analysis to ensure the product will be competitive in a global market.
