Chia Seed Oil

We'll be the first to admit that until not too long ago, the mention of chia seed oil brought to mind the tiny seeds that you eat in a rich pudding and not a skincare ingredient rich in antioxidants and emollients. And as beneficial for your health as chia seeds are (not to mention tasty), can you blame us? But as cosmetic chemist Marisa Plescia points out, chia seed oil as a skincare ingredient deserves some recognition, too.

TYPE OF INGREDIENT: Non-fragrant plant oil.

MAIN BENEFITS: Moisturizes, protects from free-radical damage, and improves dryness and itchiness.

WHO SHOULD USE IT: Mudgil says thanks to its versatility, chia seed oil, in general, offers benefits for all skin types. Russak adds that anyone with sensitive, inflamed, and dehydrated skin would particularly benefit from chia seed oil in their routine, and it even works well for irritated and oil-prone skin.

HOW OFTEN CAN YOU USE IT: Mudgil says chia seed oil is generally safe to use on a daily basis but stresses the importance of listening to your skin and adjusting accordingly.

WORKS WELL WITH: Even though chia seed oil is high in antioxidants, Plescia points out that it lacks a high vitamin C concentration, so using vitamin C in conjunction with chia seed oil could boost its skin benefits, which includes reducing signs of aging. Plescia adds that astaxanthin, an ingredient that's high in vitamin C and E, can especially enhance the effectiveness of chia seed oil.

DON'T USE WITH: Plescia says chia seed oil can be used in conjunction with many cosmetic ingredients.

What Is Chia Seed Oil?

Chia seed oil (or, more formally known as salvia hispanica seed oil) is—you guessed it—extracted from the seeds of the chia plant. Plescia says as a food, chia is a powerhouse source of fatty acids, dietary fiber, proteins, vitamins, minerals, polyphenols, and antioxidants, such as caffeic acid, rosmarinic acid, myricetin, and quercetin.

Skin benefits aside, part of what makes this ingredient such a great one to include in cosmetic formulation is that it’s very stable, and it's also resistant to oxidation, according to Plescia. It's available in pure form, but because of its levels of fatty acids, it's commonly used in moisturizers and can also be found in eye creams, lip products, and even haircare products.

Benefits of Chia Seed Oil for Skin

Because chia seed oil is so versatile, Mudgil says it offers benefits for all skin types. Here's how this nutrient-dense ingredient can improve the skin:

Moisturizes the skin: Mudgil notes that chia seed oil is rich in emollients, which makes it an effective moisturizer and works to soften the skin and improve the skin barrier function.
Protects from free-radical damage: The strong antioxidant properties of chia seed oil help protect the skin from oxidative damage and free radicals (which play a major role in skin aging) due to environmental aggressors, such as UV radiation or pollution.
Improves dryness and itchiness: Russak adds that chia seed oil can also work to improve pruritis (itchy skin) and xerosis (dry skin). In fact, Plescia points to an eight-week study of patients suffering from xerotic eczema who used a simple cream with 4% chia seed oil that found significant improvements in skin hydration and skin barrier function and reduction of itchiness.
Increases skin hydration: Russak says not only can chia seed oil help with skin hydration, but it can also decrease transepidermal water loss.
Is an antioxidant ingredient: Chia seed oil has strong antioxidant properties and is full of highly beneficial ingredients for the skin.
Rich in fatty acids: When it's used in skincare, chia seed oil is especially beneficial because of its composition of fatty acids. It contains linoleic acid (omega-6 fatty acid) and more than 60% alpha-linolenic acid (omega-3 fatty acid), which, Plescia explains, is one of the highest for any plant source.

Side Effects of Chia Seed Oil

According to Plescia, chia seed oil is a safe and effective ingredient to use in beauty products for any type of formula and skin area. Chia seed oil is easily tolerated, and Russak even says the ingredient could be used on irritated, inflamed, and oil-prone skin. "I would only recommend avoid using if someone has an allergy to chia seeds," Russak says.

How to Use It

Russak recommends applying the oil on clean skin after cleansing the face as the next step in your skincare routine, so it absorbs and does not get diluted by the other products. Allow a few minutes for the product to soak in before applying your moisturizer and sunscreen. Russak adds that due to its antioxidant properties, chia seed oil is best used in the morning to decrease the effects of exogenous stressors on the skin.

Topical Chia Seed Oil vs. Edible Chia Seeds

Chia seeds are great for your health, but you already knew that. Plescia says the benefits of chia seed consumption are well documented, and chia seeds are considered to be one of the most nutrient-rich foods in the world. High in protein, fiber, and linolenic acid (omega-3 fatty acid), Plescia describes chia seeds as a heart-healthy food, but adds that studies that correlate the ingestion of chia seeds with skin health and skin benefits are limited.
