Biotaderm Flow Dry Face Moisturiser
Nourishing face moisturiser for dry skin
The lightest of the three textures, made for facial skin that runs dry. Over nine percent of the formula is plant oil, enough to soften and hold moisture without sitting heavily. Every ingredient and every percentage is published below.
What it is, and who it’s for
Flow is our face texture. It carries over nine percent plant oils, which is generous for something this light, and the blend here leans on the oils that suit dry skin: baobab and evening primrose in equal measure, jojoba for a finish that does not feel occlusive, tamanu for conditioning, and a little sea buckthorn for its carotenoids.
Around those are the ingredients every Biotaderm formula shares, including a postbiotic barley ferment, the plant prebiotic inulin, plant squalane, allantoin and vitamin E. The formula is built at skin pH and held there by sodium citrate, which is the plainest thing we do for the skin microbiome and the best evidenced.
It suits skin that feels tight after washing and stays that way through the day.
Warm a small amount between your fingertips and press it into clean skin, once or twice a day, before any cosmetics or sunscreen. Only a little is needed. Avoid the immediate eye area.
How it feels
A light cream that spreads smoothly and easily. A pea-sized amount will cover the whole face, and it spreads thin without dragging.
Absorbs quickly with little rubbing, leaving a satin finish that sits well under make-up or sunscreen.
The plant oils, with the earthy, slightly citrus note of the vetiver. You notice it for a few minutes, then it fades.
Key ingredients
Five oils do the work here, chosen for dry skin rather than for how they read on a label. Each has its own entry in the ingredient library, with the evidence and its limits set out in full.
Baobab Seed Oil Adansonia Digitata
A balanced oil that softens and helps skin hold onto moisture, without the heaviness of the more occlusive butters. Organic and cold-pressed.
Evening Primrose Oil Oenothera Biennis
One of the few plant oils rich in gamma-linolenic acid. Studies suggest GLA-rich oils support barrier function in skin that is dry and easily provoked, and it has a long record of comfortable use.
Jojoba Seed Oil Simmondsia Chinensis
Technically a liquid wax rather than an oil, and close enough in structure to the skin's own sebum that it sits well on most people. It conditions without feeling like a layer.
Tamanu Seed Oil Calophyllum Inophyllum
A thick, conditioning oil with a long history of traditional use on damaged and irritated skin. The published evidence is thinner than the folklore, so we use it for what it demonstrably does, which is soften and soothe.
Sea Buckthorn Fruit Oil Hippophae Rhamnoides
Present in small quantity, and deliberately so. It is dense in carotenoids, which is where its antioxidant interest lies, and also where its strong orange colour comes from. Past a certain level it would tint the cream and anything it touched, so the amount here is set by that limit rather than by ambition.
Bladderwrack Fucus Vesiculosus, our signature Atlantic seaweed
The same species you will find on the rocks below Welcombe at low tide. Ours is a cold, solvent-free infusion in sunflower oil, made in the UK. The infusion carries fucoxanthin, the seaweed's golden pigment, which gives it a modest antioxidant character, helped by the vitamin E in the sunflower oil that carries it. That, and the brand's ties to this coast, is why it is in every formula we make.
Every Biotaderm moisturiser also contains squalane, a postbiotic barley ferment upcycled from gin distilling, the plant prebiotic inulin, allantoin, vitamin E and chlorella.
Every ingredient is named on the label, with nothing hidden under "fragrance" or "parfum", so you can check the formula against anything your skin dislikes. If your skin reacts easily, patch test on the inside of your forearm before first use.
This formula contains one essential oil, vetiver root oil, at a tenth of a percent. Vetiver root oil is rich in antioxidant compounds, chiefly the vetivones, and the research that identified them tested the same steam-distilled root oil we use. It also gives the cream its quiet, earthy scent and softens the sharper notes of the cold-pressed oils.
It appears on the label under its own name, never inside a "parfum" catch-all. That is why we describe the range as having no synthetic fragrance rather than as fragrance-free.

Common questions
Flow, Core or Deep? How do I choose?
By where you are putting it rather than by how dry your skin feels. Flow is the lightest of the three and is built for the face, at around nine percent plant oils. Core carries more and suits the body. Deep carries most and is for hands, elbows and feet, the places that take a battering.
The skin type is the second choice, and that one is about how your skin behaves. The skin type finder sorts it in two questions.
Can I use Flow on my body as well as my face?
You can, though you will get through it quickly. Flow is formulated light enough for facial skin, so on arms and legs you end up using rather a lot of a 150ml bottle to cover ground that Core would handle with less. If you want one product for both, Core is the more sensible buy.
My skin reacts to essential oils. Should I try this one?
There is one essential oil in here, vetiver root oil, at a tenth of a percent. It is named on the label under its own name rather than hidden inside a parfum listing, so you can see exactly what you are dealing with.
Whether that suits you is something only your skin can answer. If you have reacted to aromatics before, patch test on the inside of your forearm and leave it a couple of days before putting it near your face.
