What does it help with?

Wave Serum is a powerful hydration serum that helps dry and irritated skin. It is packed with humectants that deeply hydrate the skin leading to healthier-looking skin.

How do I use Wave Serum?

Apply a thin layer to face and neck. We recommend AM and PM use.

Where does it fit in my routine?

It would be best if you used it right before your moisturizer. It helps spread your moisturizer so that you won't need a lot. If you have really dry skin, you can opt to use it right after cleansing. It is not an occlusive so it won’t block the penetration of other actives.

How soon will I see results?

You'll see plumper-looking skin within 24 hours. You'll often notice the results when you wake up the next day if you use it at night.

Why Wave Serum

Wave Serum hydrates deeply and immediately, then gets to work. Powered by Tidal Complex, our rigorously tested series of humectants, it delivers long-lasting hydration with cutting-edge actives that help reinforce the skin’s moisture barrier.

How It's Different

We pulled out all the stops to deliver industry-leading hydration when tested immediately after use, and up to 8 hours post-use.

Regimen Tip

Wave boosts the effects of moisturizers, so use right before or mixed with C.R.E.A.M. (or your moisturizer) for extra hydration.

The Regimen Standard

We obsess over the research, then obsess over the product. We test against the best and publish the full results. If we can’t perfect it, we don’t make it.
