Key Ingredients

Hyaluronic Acid (HA)

Produced naturally by the skin, but less and less with age, hyaluronic acid can contain up to 1000 times its weight in water. It allows hydration of the deep layers of the skin, creating a plumping effect and reducing the appearance of wrinkles and fine lines. Our proprietary HA blends eliminate all types of glycols and optimize the delivery of active ingredients.

Organic White Meadowfoam

Highly concentrated in fatty acids, white meadowfoam is known to improve the skin's natural moisture barrier. As a result, the skin gets a soft, smooth and silky fell.

Organic Australian Wild Rosella (Hibiscus) 

Wild rosella is a resilient flower, adapted to the harsh conditions of northern Australia. Concentrated in antioxidants and vitamins A, C and E, it also has a very high content of natural betaine. This gentle compound helps the skin to balance and maintain its moisture level.

Organic Algae Extract

One of the best sources of iodine, vitamins B and E, Sea Kelp possesses wealthy amounts of essential vitamins, minerals, amino acids, and antioxidants. It also protects the skin from environmental pollutants, thus keeping the skin looking as vibrant and supple as possible.

Organic Aloe Vera

Aloe vera has many dermatological benefits in addition to its moisturizing properties. Filled with antioxidants and vitamin C, it is also beneficial in the treatment of inflammatory skin diseases.

Why are your serums called Ultra Serums? What is the difference with traditional face serums?

As a whole new generation of facial serums, Ultra Serum stands for “Ultra Concentrated, Ultra Efficient”.
The result of years of laboratory research, our Ultra Serums are packed with powerful bioactive plant extracts and concentrated with up to 2% in hyaluronic acid. Non-oily and with a pleasant texture, halfway between an ordinary serum and a gel, they help reinforce hydration and effectively target the signs of skin aging (fine lines and loss of firmness) and its imperfections.

Is this serum suitable for my skin type?

ACQUA is suitable for all skin types, especially for oily, combination, dry-to-sensitive and mature skins. Also it does not contain essential oils.

This product contains hyaluronic acid, why is it so important?

All of our water-based serums and mists, as well as our anti-ageing creams, contain a hefty amount of hyaluronic acid.
This tiny molecule has huge effects! Hyaluronic acid is known for its essential role in fighting the signs of skin aging. In addition to deeply moisturizing the skin, it helps restore its softness, firmness, structure and elasticity.
That's why we've developed a new generation of concentrated formulas that combine high and low molecular weight hyaluronic acid fragments with other highly effective natural ingredients.

Do you use phenoxyethanol, parabens or glycols?

No. Also we do not use any of the so-called -dirty dozen-: parabens, fragrances, sodium laureth sulfate (SLS), triclosan, petrolatum, PEGS, formaldehyde-releasing preservatives, siloxanes, DBP dibutyl phthalate), Cocamide DEA and Lauramide DEA, BHA and BHT, coal-tar dyes (C.I.).

Hydratation parfaite

C’est un produit que j’achète plusieurs fois par an (avant même d’en terminer un, j’achète le suivant)! Un indispensable à ma routine beauté. Je l’utilise juste avant à crème de nuit.

Bien hydratant et très doux

J'adore ce sérum. Je l'utilise le matin suivi de mon sérum FUSION que j'utilise matin et soir. Je suis cette routine suggérée par FEY car ma peau sensible est aussi très sèche, et à date ce ont les meilleurs produits que j'ai utilisé pour hydrater et apaiser ma peau. je recommande.

Michelle K.
Peau douce et hydratée rapidement

J'adore la texture de ce sérum: bien que proche de celle d'un gel, le produit pénètre très vite ma peau et ne laisse aucun résidu. Ma peau est immédiatement plus douce et plus souple.
Je recommande vivement.
