Coenzyme Q10 (CoQ10): The Science-Backed Skin Benefits You Need to Know

Good skincare today goes far beyond covering up imperfections. It’s about supporting your skin’s daily repair process — and coenzyme Q10 (CoQ10) is one of the key players in that process. Without enough of it, skin cells struggle to renew themselves efficiently, and the damage caused by oxidative stress lingers, accelerating visible signs of ageing.

A 1999 study by Hoppe et al., published in BioFactors, found that topically applied coenzyme Q10 effectively protects the skin from free radicals — reducing wrinkles and strengthening the skin’s natural protective barrier (Source: https://pubmed.ncbi.nlm.nih.gov/10416055/).

Why Does Coenzyme Q10 Decline With Age — and Why Does It Matter?

Prahl and colleagues (2008) found that coenzyme Q10 production drops significantly as we age, creating what’s often described as a functionally anaerobic state in skin cells — meaning less energy is available for repair and regeneration. As a result, skin starts to lose firmness, fine lines and wrinkles appear, and the ageing process speeds up (Source: Lain et al., 2024, discussing Prahl et al., 2008: https://pmc.ncbi.nlm.nih.gov/articles/PMC11324190/).

Muta-Takada and colleagues (2009) went further, confirming that oral coenzyme Q10 supplementation significantly improves skin’s appearance, reducing wrinkles and improving elasticity after just a few weeks of use (Source: https://pubmed.ncbi.nlm.nih.gov/21888842/).

How Does Coenzyme Q10 Work in Skincare?

Applied topically, coenzyme Q10 acts as a powerful antioxidant, neutralising the free radicals that damage skin and accelerate the ageing process. Recent research suggests that coenzyme Q10 also stimulates collagen and elastin production — in turn improving skin hydration, strengthening the skin’s protective barrier, and helping defend against UV-induced oxidative stress (Kostrzewska, 2022; Gałka, 2010).

Oral supplementation has its benefits, but its cosmetic effect is more limited. That’s because once CoQ10 is absorbed through the digestive system, it has to pass through several stages of metabolic conversion — meaning only a small fraction actually reaches the skin. So while supplementation can support overall health and cellular oxygenation, its effect on skin appearance is weaker and takes longer to become visible. Applying coenzyme Q10 directly to the skin bypasses these barriers altogether: the ingredient reaches the epidermis and dermis directly, where it can act faster and more effectively to support anti-ageing and skin repair. This is echoed in research including work by Mito-Pharma (2022) and Kostrzewska (2022).

Our Serum +Q10: Maximum-Strength Coenzyme Q10 for Real Results

That’s why our Serum +Q10 is formulated with the maximum concentration of coenzyme Q10 — 1%. In my view, this is the concentration that delivers genuinely visible skincare results. A lower dose simply wouldn’t provide the clear improvement in skin condition you’d expect from an anti-wrinkle serum.

We commissioned professional instrumental testing to confirm our formula’s efficacy. After 6 weeks of regular use, participants saw an average 7.1% improvement in skin tone, an 11.3% increase in smoothness, and up to an 18% reduction in wrinkle depth. These results make a genuine difference — proof that our serum doesn’t just promise results. It delivers them.

What’s more, the serum has passed dermatological testing confirming it’s hypoallergenic — making it safe for sensitive skin too. That matters enormously to me, because I want this product to work for as many people as possible.

Who Is Coenzyme Q10 Best Suited For?

It works best for anyone noticing the first signs of ageing — loss of firmness, the first fine lines and wrinkles, dehydration, uneven tone, or a tendency towards irritation. CoQ10 is also a valuable support for skin prone to redness and visible broken capillaries, or skin that tends towards inflammation.

How to Use the Serum +Q10?

Apply the coenzyme Q10 serum morning and evening onto cleansed skin, then gently massage in. To lock in optimal hydration and get the most out of the active ingredients, we recommend following with a moisturiser.

The Bottom Line

Coenzyme Q10 is a scientifically proven ingredient that doesn’t just protect skin from ageing — it helps regenerate and strengthen it from within. Making Alexandra Kubas serum part of your regular routine is an investment in healthy, firm, radiant skin.

I stand fully behind this article, because I know this serum is the result of hard work and rigorous research — research that always puts skin first.
