Used 3-4 drops only; it’s not the right shade for me. Turns out I’m a 3 not a 2, or a mix of them. My loss your gain. The product itself is amazing.

Formulated with vitamin C for radiance and squalane & aloe vera for deep, long-lasting hydration. 99% naturally derived. Vegan. Made in France. 30ml / 1 fl.oz.
