The overwhelming opinion within the skincare community is that vitamin F should be your skin's new BFF. But what is it? Well, in short, vitamin F is fat. In skincare, vitamin F is used to represent linoleic acid, an essential fatty acid that is rich in omega-6. Fats are also known as lipids, and they're incredibly important when it comes to maintaining a strong, healthy stratum corneum (the protective outer layer of the skin). If your skin barrier function is working optimally, it'll prevent aggressors from getting in and causing water loss. We spoke to Jeannel Astarita, founder, and CEO of Just Ageless, a premier body sculpting and beauty lab in Manhattan. Astarita swears by vitamin F, saying, "[Vitamin F is] an ideal ingredient in post-treatment care due to [its] anti-inflammatory, healing, nourishing and moisturizing properties. It is necessary for the development of the lipid membrane of our cells, giving them resiliency."

What Is Vitamin F?

Vitamin F is, well, a vitamin—but not by standard definition. It more accurately fits the description of a fat, essential fatty acid, or lipid. "Vitamin F is an essential fatty acid meaning it is absolutely essential to the growth and regeneration of healthy cells, but we cannot synthesize it on our own.", states Astarita. You've probably seen many skincare products formulated with this potent ingredient, but it's most often labeled as linoleic acid (which is an omega-6 essential fatty acid). Vitamin F can be sourced in a multitude of food choices, such as almonds, chia seeds, hemp seeds, and egg yolks, and can also be found in a handful of essential oils such as rosehip, chia, and argan. And while it's important to slather vitamin F onto your face and body, eating good fats can also help to nourish your skin, hair, and nails from the inside out. It also has an anti-inflammatory effect, and as we all know by now, inflammation is one of the critical causes of aging. A little science for you: Inside the body, omega-6 is used to make ceramide I, which is a vital part of a healthy skin barrier. It helps your skin's cells retain moisture. Skin that lacks vitamin F can look dry, dull, scaly, and be acne-prone. Studies have found that people with atopic dermatitis generally require ceramide I.

Benefits of Vitamin F for Skin

Vitamin F is a highly beneficial—and necessary—ingredient for all skin types.

  • Retains moisture: Considered an omega-6 essential fatty acid, Vitamin F becomes ceramide when used on the skin, a hydrating ingredient that also protects the skin's barrier and retains moisture.
  • Reduces inflammation: Vitamin F can be exceptionally beneficial for those with inflammatory skin issues, such as dermatitis and psoriasis.
  • Works wonders for all skin types: Vitamin F is wonderful for all skin types when used topically. Yes, even acne-prone skin. Studies show that those who experience acne were able to reduce the pustule size by 25% in as little as one month by applying linoleic acid topically.
  • Keeps skin safe: It helps to protect the outer most layer of the skin from UV light, pollution, and infections.
