For daily use, preferably at bedtime or anytime your skin is sensitive, irritated or needs replenishing.
FUSION should be applied on freshly cleansed wet skin (use lukewarm water or tonic water spray). Gently rub 1 to 2 squirts of serum on face, neck or neckline areas in circular movements. Wait until the serum is completely absorbed before applying any other skincare product or makeup.

If you are about to use a day cream, a night cream, or any other cosmetic product, apply FUSION first.

Grapefruit Seed Extract

A vitamin C powerhouse, with great antioxidant, antimicrobial and healing properties. It also doubles as a natural preservative in cosmetics when combined with other ingredients.

Every ingredient has its specific function and has been carefully selected in combination with others that complement it to maximize its benefits.

Secondly, the regenerating properties of Tamanu and Grapefruit turn FUSION into a healing boost for troubled skin. Palmarosa acts as an agent curbing and relieving inflammation while algae supports collagen production. All in all, the fusion of these ingredients tackles multiple issues at once, enabling the skin to heal and appear overall visibly improved.

J aime ce sérum, sont tous bon


Merci pour ce merveilleux produit! C'est exactement ce qui manquait à votre gamme, j'ai toujours le contour des lèvres sec et ce produit a complètement réglé mon problème. Si vous l'intégrez de façon permanente à votre gamme, c'est absolument certain que je l'achèterai!

Fini la peau qui tiraille!

J'ai utilisé les produits Fey cet hiver sur ma peau hyper sensible et à mon grand bonheur, je n'ai pas eu la peau qui tiraille du tout! La texture du sérum Aqua est merveilleuse et j'adore l'odeur délicate! Il laisse ma peau bien hydratée, avec un beau fini lisse mais sans effet gras!

Excellents produits

Ma peau est bien hydratée et lissée. Ce sont d'excellents produits québécois et vegan. Les contenants sont très robustes et opaques, je suggère d'éviter les boîtes de carton pour rendre le produit plus écologique.

Excellente collection pour peau sensible

Tous les produits de ce rituel sont incroyables. Le sérum Acqua a été un vrai miracle pour les zones les plus sèches de ma peau. La crème de Jour Perle pénètre très rapidement et ne laisse pas la peau grasse. Le sérum Fusion a amélioré la texture et l'apparence générale de ma peau. Je les recommande aux peaux les plus sensibles. Après 2 semaines d'utilisation, ma peau n'a pas réagit négativement à aucun des produits.
