What Is Coenzyme Q10?

Coenzyme Q10 (INCI name: ubiquinone) is a compound naturally present in the body, including in the skin. In cosmetics, it's prized as a powerful antioxidant — one of that helpful family of ingredients that support skin against the everyday free-radical and environmental stress linked to the appearance of ageing and dullness. Skin's natural Q10 levels tend to decline with age and factors like sun exposure, which is part of why it's such a popular topical antioxidant. Cosmetic Q10 is plant-derived, made from corn by fermentation.

CoQ10 is one of those antioxidant names that's been beloved in skincare for decades — and for good reason. Let's look at what it honestly does, and how to think about it.

The Antioxidant Star

Defending Against Everyday Stress

CoQ10's headline role is as an antioxidant. Our skin faces daily free-radical and environmental stress — from pollution, sun, and lifestyle factors — that's associated with the appearance of dull, tired, prematurely-ageing skin. Antioxidants like Q10 help support skin's defences against that everyday stress, helping it look fresher and healthier for longer.

Naturally in Skin

A Skin-Familiar Ingredient

One reason Q10 is so appealing is that skin already makes it — it's naturally part of our biology. Levels tend to decrease with age and with factors like sun exposure, stress, and lifestyle. That skin-familiarity is part of why topical Q10 is such a well-liked, gentle antioxidant choice.

Smoothing, Hydration & Radiance

Smoothing

Q10 has a smoothing quality, helping support the appearance of smoother, more refined-looking skin — which is why it often appears in products focused on the look of fine lines.

Moisturising & Radiance

It also has moisturising qualities that support the appearance of hydrated skin, and helps support an overall radiant, healthy-looking glow. And it has a soothing quality, adding to its comfortable, skin-friendly feel.

Antioxidants Love SPF

A Perfect Daytime Partnership

Antioxidants like Q10 and sunscreen are a classic daytime team: SPF is your essential shield against UV, while antioxidants help support skin against everyday environmental stress. To be clear — an antioxidant is not a sunscreen and gives no UV protection. Think of Q10 as a lovely complement to, never a replacement for, your daily broad-spectrum SPF.

Who It's For

A Lovely Fit For:

All skin types — gentle, non-irritating, well tolerated
Dull, tired-looking skin — for antioxidant support and radiance
Those focused on the look of fine lines — a popular smoothing antioxidant
Anyone building an antioxidant + SPF daytime routine

A Realistic Note

A Well-Loved Antioxidant

CoQ10 is a gentle, popular antioxidant that supports the appearance of fresh, smooth, radiant skin. Its benefits relate to the look and feel of skin — not to treating any condition or changing skin's underlying biology. Like all antioxidants, it works best as part of a consistent routine, paired with daily sun protection.
