Algae, think seaweed, kelp, spirulina, microalgae, is a skincare staple for a reason. Listed as Algae Extract (often from Laminaria digitata), it helps skin stay hydrated, soothed, and fresh. Here’s what it does and why it’s worth a spot in your routine.
What it is
Algae are water‑dwelling plants and micro‑plants, think seaweed, that are naturally rich in water‑binding sugars, minerals and gentle antioxidants. In skincare, those goodies are turned into silky gels and lightweight creams that give skin a soft, bouncy finish without heaviness.
In plain terms: algae is a natural hydrator and comfort‑giver that makes formulas feel amazing on the skin.

Why it works
- Instant, lightweight hydration (hello, bounce): Ever notice how some products feel wet at first and then you’re dry again an hour later? Algae helps avoid that. Its water‑loving sugars act like tiny sponges, helping your skin hold on to moisture so it looks plumper and smoother for longer. Think of it like slipping on a soft T‑shirt instead of a plastic raincoat, breathable comfort, not clingy.
- Brings calm and comfort: Weather swings, over‑cleansing, a new active, skin can throw a little tantrum. Algae has a naturally soothing side that helps settle the look of redness and that “too tight” feeling without adding heaviness. It’s not dramatic; it’s steady and reassuring like a deep breath for your face.
- Daily defense: Life happens, screens, city air, sun exposure. Algae’s natural antioxidants offer everyday support against those stressors (you’ll still want your SPF, of course).
- That fresh, dewy finish: Algae is a texture magician. It gives products a clean, cushiony glide and a soft‑focus glow that sits beautifully under makeup or on bare skin.
- Plays nicely with others: Using vitamin C, niacinamide or a gentle retinoid? Algae layers easily and boosts the comfortable, well‑hydrated feel of your routine.
- Suitable for all: Dry yet breakout‑prone? Oily but dehydrated? Sensitive and selective? Algae is lightweight and flexible, so it fits many skin personalities. It gives water where you need it, comfort where you want it, and doesn’t pile on extra weight.
Think of algae as the fabric of a great wardrobe: silky, effortless, and luxurious. It is light, comforting, and deeply connected to moisture, exactly the kind of ingredient we wanted at the heart of our Silky Marine Night Cream.
In our night cream, we use Laminaria digitata, a brown algae also known as kelp, with the extract produced in-house here in Switzerland. It brings a marine-inspired touch to the formula and works alongside argan oil, hibiscus flower extract, and vitamin E to support the skin overnight.
Our Silky Marine Night Cream is part of La Collection Sable et Mer®, created as the evening step to complement Desert Glow® Day Cream. Together, they bring the story of desert and sea into a simple daily routine: glow by day, comfort by night.
