Biotaderm Core Oily All-Over Moisturiser
Cushioning moisturiser for oily skin, anywhere you need it
The most versatile of the three textures, made to go anywhere on the body, and onto the face when it wants more than Flow. Over fourteen percent of the formula is plant oil, chosen from the lighter, faster-absorbing end rather than the rich end. Every ingredient and every percentage is published below.
What it is, and who it’s for
Core sits between the other two. It carries over fourteen percent plant oils against Flow's nine, which is the difference between something that disappears on the face and something that stays put on arms, legs and shoulders.
Oily skin still has a barrier to look after, so the oil content is the same as any other Core. What changes is which oils: rose hip and grape seed in equal measure, dragon fruit, and argan, all from the light end. Around those sits the same supporting cast as every Biotaderm formula, built at skin pH and held there by sodium citrate.
If you only want one moisturiser, this is usually the one.
Smooth a small amount over clean, dry skin once or twice a day, wherever you need it. It spreads without warming first, so you will use less than you expect. Before any cosmetics or sunscreen if you are using it on the face.
How it feels
A medium-light cream that spreads across the body without warming it first. A little covers more ground than it looks.
Absorbs quickly with light rubbing, leaving skin moisturised, not greasy, and ready to get dressed.
The plant oils, with the earthy, slightly citrus note of the vetiver. You notice it for a few minutes, then it fades.
Key ingredients
Four oils do the work here, all from the lighter end. Oily skin still has a barrier to look after, and harsh products can strip it. Each has its own entry in the ingredient library, with the evidence and its limits set out in full.
Rose Hip Seed Oil Rosa Canina
Rich in linoleic and linolenic acids, the fatty acids the barrier is built from. Linoleic acid matters particularly here, because sebum in oily skin tends to run low in it. Organic and cold-pressed.
Grape Seed Oil Vitis Vinifera
One of the lightest oils we use, high in linoleic acid and quick to absorb. It lets the formula carry a generous share of oil without feeling heavy.
Dragon Fruit Seed Oil Hylocereus Undatus
A light seed oil, rich in linoleic acid, with antioxidant activity from its tocopherol content. It sits well on skin that finds heavier oils uncomfortable. Cold-pressed.
Argan Kernel Oil Argania Spinosa
High in vitamin E and used here in a small amount, for its emollient character rather than for the reputation that precedes it. Organic and cold-pressed.
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 Core on my face?
Yes, and plenty of people do, particularly in winter. Core carries around fourteen percent plant oils against Flow's nine, so it sits heavier and takes longer to sink in. If you wear make-up or sunscreen over the top you will probably prefer Flow on your face and Core everywhere else.
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.
