What's in it

The shortest ingredient list we make.

Everywhere else on this site we argue that more actives, kept intact, is the harder thing to do. This product is the opposite argument. A hydrating base has one job, and every ingredient that isn't doing that job is something else for your skin to react to.

No fragrance. No essential oils. No silicones. No alcohol. No dye. No plant extracts — which sounds like a shortcut and is the opposite: botanicals are the most common cause of a reaction in a product like this.

If you're used to reading ingredient lists, you'll notice two things. Sodium hyaluronate and hyaluronic acid are both here. They're not the same ingredient twice — they're different molecular weights, and they do different jobs at different depths.

The preservative system is two ingredients, not five. Hydroxyacetophenone and 1,2-hexanediol, no parabens and no phenoxyethanol. On a formula this simple you can get away with a lighter system, so we did.

Why two of them

Hyaluronic acid isn't one ingredient.

It's a family of molecules that behave differently depending on size. Most inexpensive HA serums use one weight, because one is cheaper and the label reads the same.

Higher weight
Hyaluronic acid
The large molecule. It stays at the surface and holds water there, which is what makes skin feel plump and smooth within minutes of applying it. It doesn't go deep, and it isn't meant to.
Lower weight
Sodium hyaluronate
The smaller, salt form. It's more soluble and sits further into the upper layers, so the hydration lasts past the first hour rather than evaporating off with the surface film.
Panthenol
Vitamin B5
A humectant that also supports the barrier — it's the reason a formula this simple still feels soothing rather than just wet. It's what turns a hydration serum into a recovery one.

    Magic in a bottle

    I’m not sure what’s inside of this serum but seriously feels like magic in a bottle. My skin is always so much brighter after I apply it!

    Never knew I needed this

    Bought this in hopes it would work for me, very glad I did.

    This serum has been great for my skin, I have sensitive skin and have had no problems. Super moisturizing.
