Ingredients

Six things. Nothing else.

Most creams have thirty ingredients because thirty ingredients is what it takes to make something cheap feel expensive. Rü has six because six is what the job needs.

How it works

Your barrier is a wall. Most creams water it.

The wall gets gappy

Your outer layer is skin cells held together by lipids. Hot showers, wind, retinol, cheap surfactants and age all thin those lipids out. Water walks straight out through the gaps.

02 / 04

Most creams add water

A standard oil-in-water lotion is mostly water with a little oil floating in it. It feels great for twenty minutes. Then the water evaporates and takes some of yours with it.

Rü is built the other way round

Water-in-oil. The oil phase is the outside, so it stays on the surface as a breathable film while the water sits underneath, where your skin can actually use it.

04 / 04

The gaps close

Shea, jojoba and glycerin refill the lipid spaces. The wall goes back to doing its job. That is the whole product. No actives shouting over each other.

Macro of skin hours after the cream: smooth, holding water, no film sitting on top
