The walnut is much more than a superfood for the brain and heart. It is also one of the most complete ingredients nature can offer the skin. Thanks to its unique richness in polyphenols, essential fatty acids (omega-3), and tocopherols (vitamin E), it acts as an anti-inflammatory, antioxidant, and regenerating shield.

In this article, we decode these super-ingredients, their mechanism of action, and why they are at the heart of Novëm skincare, to offer an effective response for sensitive, reactive skin prone to redness.

Why are natural active ingredients so powerful for the skin?

Because they act in synergy: antioxidants (like polyphenols and vitamin E) limit cellular damage, while fatty acids (omega-3) repair the skin barrier and reduce inflammation.

The unique feature of the walnut is that it combines these 3 major families of active ingredients into a single seed. This is what makes it an exceptional ingredient.

1. Polyphenols: the antioxidants of youth

What are they?

Polyphenols are plant molecules naturally present in the shell and the thin skin of the walnut kernel. They possess a high capacity to neutralize free radicals, which are responsible for premature skin aging.

Their benefits for the skin:

• Protect skin cells from oxidative stress (pollution, UV, stress…)

• Reduce chronic inflammation (redness, heat…)

• Prevent skin aging (loss of firmness, dark spots…)

• Improve skin radiance

💡 At Novëm, we extract these polyphenols using a respectful process to preserve all their power without denaturing them.

2. Omega-3: natural anti-inflammatories

Present in large quantities in…

👉 Cold-pressed walnut oil, derived from the kernel

Alpha-linolenic acid (ALA), an essential omega-3, is recognized for its properties:

• Anti-inflammatory

• Soothing

• Regenerating

• Skin barrier strengthening

In cosmetics, they act as:

• A calming agent for reactive skin and skin prone to redness

• A lipid repairer for dry or atopic skin

• A balancer to restore skin comfort

💧 The Novëm face oil based on walnut oil is particularly rich in omega-3: it deeply hydrates while regulating the skin's inflammatory reactions.

3. Tocopherols (vitamin E): the antioxidant barrier

What is vitamin E used for?

It is one of the most powerful antioxidants for the skin. Naturally present in walnut oil, it:

• Protects skin lipids from oxidation

• Preserves skin elasticity

• Promotes healing and tissue repair

• Extends the natural shelf life of vegetable oils

🧴 Every Novëm skincare product contains natural vitamin E, added to the oil to preserve its stability without synthetic preservatives.

What science says about it

Study 1 – Polyphenols and skin inflammation

A study published in Oxidative Medicine and Cellular Longevity (2018) shows that walnut polyphenols reduce the activity of pro-inflammatory cytokines on skin cells.
➡️ This confirms their potential in anti-redness and sensitive skin care.

Study 2 – Omega-3 and skin barrier

A review published in The Journal of Clinical and Aesthetic Dermatology (2020) shows that topical application of ALA improves barrier function and reduces erythema.
➡️ Relevant for skin suffering from dryness, rosacea, or dermatitis.

A unique synergy in the walnut

What makes the walnut exceptional is the synergistic concentration of these active ingredients in a single raw, organic, local, cold-pressed ingredient.
And it is this richness that Novëm captures in each of its skincare products, to offer a solution that is:

• Natural

• Scientifically founded

• Environmentally and skin-conscious
