Great for skin tightening!

Excellent serum with an instant (light) lifting effect. I’ve been using it for more than a year now and found it to make a real difference with my skin hydration and firmness. Texture is very nice and it absorbs very quickly.

What’s really nice about this product is that it’s not only tightening my skin but also moisturizing it! Really a 2-in-1 product!!!

Beau produit

Le sérum s’applique très bien et laisse une sensation agréable. J’aime aussi que ces produits soient naturels. Bien que je ne constate pas d’amélioration marquée en ce qui a trait à la fermeté de ma peau, celle-ci est plus douce.

Josee T.

J’utilise les produits depuis 10 jours et je vois une nette amélioration . Ma peau est plus hydraté , je n’ai aucune réaction car les ingredients sont de qualités . C’est un plaisir d’effectuer ma routine matin et soir . Très heureuse d’avoir découvert FEY 💓
