Vitamin F in Skincare — The Barrier-Loving Lipid
Science Reviewed · Boldpurity Science Team
Last reviewed: July 2026
Quick Answer
"Vitamin F" isn't really a vitamin — it's a friendly name for a group of essential fatty acids (mainly linoleic and linolenic acid), often sourced from safflower oil. These are the same kinds of fatty acids that make up part of your skin's own protective barrier. In skincare, Vitamin F works as a nourishing emollient that softens, replenishes, and helps support the appearance of a healthy, comfortable skin barrier. It's especially loved for dry and sensitive skin, and it's very well tolerated.

What Is Vitamin F?
Despite the name, Vitamin F isn't a true vitamin. It's a traditional nickname for a group of essential fatty acids — primarily linoleic acid and linolenic acid — that the body can't make on its own. In skincare, these are usually derived from cold-pressed vegetable oils like safflower oil. Because they're the same type of lipids that form part of the skin's natural barrier, applying them topically works as a nourishing emollient — softening skin and helping support the appearance of a healthy, comfortable barrier.
Some of the best things for dry, uncomfortable skin aren't fancy actives — they're the simple lipids your skin barrier is partly made of. Vitamin F is exactly that: a nourishing blend of essential fatty acids that feels like giving your skin something it already recognises.
Here's what it does and why dry, sensitive skin loves it.
Why It's Called a "Vitamin"
A Historical Nickname
Decades ago, essential fatty acids were thought to behave like vitamins — nutrients the body needs but can't produce itself — so they were dubbed "Vitamin F." The name stuck, even though we now know they're fatty acids, not true vitamins. So if you see "Vitamin F" on a label, think essential fatty acids (linoleic and linolenic acid) — nourishing lipids, not a vitamin in the classic sense.
How Vitamin F Works
Softens & Nourishes
As an emollient, Vitamin F softens and smooths the skin's surface, helping dry, rough-feeling skin feel supple and comfortable again.
Replenishes Barrier Lipids
Because these are the same kinds of fatty acids found in the skin's barrier, Vitamin F helps replenish the surface lipids — supporting the appearance of a healthy, resilient barrier that holds moisture better.
Comforts Dry, Sensitive Skin
Its gentle, skin-familiar nature makes it comforting for dry and sensitive skin that feels tight, rough, or in need of some nourishment.
What Vitamin F May Help With
Dry, Rough Skin
Softens and smooths, helping skin feel supple and comfortable.
Barrier Comfort
Supports the appearance of a healthy, resilient skin barrier.
Sensitive Skin
Gentle and skin-familiar — a comforting choice for reactive skin.
Moisture Retention
Helps skin hold onto moisture by supporting its natural lipid layer.
Who It's For
Especially Suited To:
- Dry & dehydrated skin — nourishing, softening emollient action
- Sensitive skin — gentle, well-tolerated, and skin-familiar
- Barrier-stressed skin — for the appearance of a comfortable, replenished barrier
- All skin types — as a nourishing lipid, it fits most routines, adjusted to texture preference
How to Use It
Vitamin F usually appears as one ingredient within a nourishing formula — a moisturiser, facial oil, serum, mask, or balm — rather than as a standalone. To make the most of emollient, barrier-supporting ingredients:
- Apply after hydrating steps — emollients and lipids go on after watery humectants
- Great as a "seal" step — they help lock in the hydration from humectants beneath
- Pair with humectants — Vitamin F + a humectant (like HA or glycerine) covers both moisture needs
- Look for Vitamin E alongside it — it stabilises Vitamin F and adds antioxidant support
- Use SPF in the AM — nourished skin still needs sun protection
- Patch test first — as with any new product

Your Questions, Answered
Is Vitamin F actually a vitamin?
No. "Vitamin F" is a historical nickname for essential fatty acids — mainly linoleic and linolenic acid. They're nourishing lipids, not a true vitamin. The name simply stuck from decades ago.
What does Vitamin F do for skin?
It works as a nourishing emollient — softening dry skin and helping replenish the barrier's natural lipids, which supports the appearance of a healthy, comfortable barrier. It's especially valued for dry and sensitive skin.
Why is it paired with Vitamin E?
Essential fatty acids can be sensitive and prone to breaking down. Vitamin E (tocopherol) is an antioxidant that helps stabilise them and keep the formula fresh — so the two are often used together.
Is Vitamin F good for sensitive skin?
Yes — it's gentle, very well tolerated, and skin-familiar, making it a comforting choice for dry and sensitive skin. As always, patch test new products first.
Can oily skin use Vitamin F?
Yes, in the right formula. Linoleic acid is a lightweight fatty acid, and many oily-skin-friendly products include it. Choose lighter textures if you prefer, and let the overall formula guide you.
Can I use Vitamin F every day?
Yes — as a gentle, nourishing emollient, it's suitable for daily use, morning and evening. Apply after your hydrating steps and follow with SPF in the mornings.
Nourishment Your Skin Recognises
Vitamin F is a lovely example of skincare working with your skin — nourishing it with the same kinds of essential fatty acids its barrier is partly built from. Gentle, softening, and comforting, it's a quiet hero for dry and sensitive skin. If you spot it (often alongside Vitamin E) on an ingredient list, it's a sign of a thoughtful, barrier-loving formula.
