Hyaluronic Acid

Hyaluronic acid attracts and holds water, so skin feels hydrated and looks plumper and smoother. Every product in this collection is built on FEY's proprietary blends of low- and high-molecular-weight hyaluronic acid, each tuned for a depth and speed of action. These blends replace glycols, which is why the formulas are glycol-free.

Choose ACQUA, with vitamin C and organic hibiscus, for a wave of hydration, TONUS, with organic chlorella and rosehip, for skin that looks firmer, ÉCLAT at night, or the FUSION serum to comfort dry, sensitive skin. Finish with PERLE by day or ETERNA at night, and refresh body and hair with BRUME Refreshing or Comforting. Every product is rated 100/100 on Yuka. Learn more in our hyaluronic acid guide. Made in Montréal, Canada.

FAQS

Which FEY products contain hyaluronic acid?

All four FEY serums (ACQUA, TONUS, ÉCLAT and the FUSION serum), both face creams (PERLE for the day, ETERNA for the night) and both BRUME body and hair mists contain hyaluronic acid. Each formula pairs it with different botanical actives.

Why does FEY combine low- and high-molecular-weight hyaluronic acid?

Each molecular weight works differently. High-molecular-weight hyaluronic acid stays on the surface for an immediate smoothing feel, while low-molecular-weight hyaluronic acid works within the skin's upper layers. FEY combines both in proprietary blends, each tuned for a depth and speed of action.

Why are FEY formulas glycol-free?

In many skincare formulas, glycols such as propylene glycol or butylene glycol carry the active ingredients into the skin. In FEY formulas, proprietary hyaluronic acid blends do that job instead, so no glycol is needed. Both glycols are on FEY's ingredient black-list.

Which hyaluronic acid serum should I choose?

Choose ACQUA for a wave of hydration and skin that looks plumper, TONUS for skin that looks firmer and more toned, ÉCLAT as a nourishing night serum for a more radiant-looking complexion, and the FUSION serum to comfort skin that feels dry or sensitive.

In what order should I apply hyaluronic acid products?

Go from the lightest texture to the richest. After cleansing and your toning lotion, apply your serum while the skin is still damp so the hyaluronic acid can hold more hydration, then finish with PERLE in the morning or ETERNA at night. Read our hyaluronic acid guide.
