Amino Rain™ Glasswater Serum

Drunk Elephant Amino Rain Glasswater Serum is a hydration serum with a faint opalescent shimmer that shows up the moment it goes on. Drunk Elephant describes it as building luminosity over time while firming and calming the skin towards a glass-like look. The actives are amino acids and hyaluronic acid rather than anything exfoliating.

What it actually does

• Holds water in the skin. The 1% fermented poly amino acid — polyglutamic acid, in plainer terms — is credited by the brand with hydration that keeps going rather than fading within the hour.
• Four kinds of hyaluronic acid. The Hiya Super Hydration Water Complex is Drunk Elephant's four-acid blend. Buffering skin against free radicals in the environment is one of the jobs they give it; a visible gain in springiness is another; and the water it holds is meant to stay put for a full 24 hours.
• Firming peptide-style support. Dipalmitoyl hydroxyproline at 0.5% is described as raising hydration levels while visibly improving firmness and bounce.
• Built to be mixed. Drunk Elephant designs its range so products can be combined into what the brand calls a smoothie — the one exception is their sunscreen, Umbra, which is meant to sit on the surface and block UV.
• Formulation philosophy. The brand limits itself to ingredients that it says either benefit skin health directly or hold the formula together, with attention to pH, small molecules that absorb easily, and support for the skin's acid mantle.
• What Drunk Elephant's studies reported. In an instrumental study on 31 people, the brand recorded a 115% immediate rise in hydration lasting through the day. In a separate clinical study on 34 people, 94% showed an instant lift in radiance and luminosity, and the serum was described as clinically proven to firm and brighten across four weeks. Small panels, brand-run — individual results vary.

How to use

1. Shake it first. The formula needs a shake before each use.
2. One pump, once a day, onto skin that is clean and dry.
3. Layer it however you like. Drunk Elephant says it can sit alongside any of their serums, treatments or moisturisers.

Is it right for you?

Questions

Is the opalescence visible on the skin?

The serum is described as waking skin up with a pop of opalescence, so expect a luminous cast rather than a matte one. It is part of the glass-skin effect the product is aiming for.

Can I layer it with my other Drunk Elephant products?

Yes. Mixing is the brand's whole approach — they encourage combining serums, treatments and moisturisers. The only product they keep separate is Umbra, their sunscreen, which is meant to stay on top as a UV layer.

Morning or night?

The instruction is one pump once per day, so either works — pick whichever slot you will keep to. Just shake the bottle and apply to dry, cleansed skin.

Is it vegan?

Yes — the product is listed as both vegan and cruelty-free.
