CoQ10

CoQ10 (coenzyme Q10 or ubiquinone) is an antioxidant that helps visibly firm, tighten, and smooth skin by supporting cellular energy production within the mitochondria. It helps defend against oxidative stress that contributes to fine lines, wrinkles, dullness, and loss of elasticity while supporting collagen and elastin processes associated with firmer-looking skin. In Exponent’s clinical testing, Firming Filter CoQ10 Power Serum demonstrated measurable improvements in skin firmness, elasticity, hydration, and global facial fine lines and wrinkles after 4 weeks of use.

CoQ10 can be used twice daily, morning and night. During the day, it helps provide antioxidant defense against environmental stressors like UV exposure and pollution. At night, it supports skin recovery processes associated with firmness, hydration, and smoother texture.

Apply CoQ10 serum to clean skin before moisturizer. Exponent's activated format requires mixing the active CoQ10 powder and Hyaluronic Acid just before use to ensure full potency, then apply to face and neck AM and PM.

Some people notice improved hydration and radiance within days, while visible firming and smoothing benefits typically develop over several weeks of consistent use. In Exponent’s clinical testing, Firming Filter CoQ10 Power Serum showed a 10% reduction in wrinkle depth after just 7 days, with continued improvements in skin firmness, elasticity, and fine lines after 4 weeks.

No. CoQ10 is one of the gentlest high-performance actives available, with no purge period, no sensitivity window, and no irritation. It's appropriate for all skin types including sensitive skin.

Yes. CoQ10 is widely considered safe during pregnancy and nursing, making it one of the only clinically effective anti-aging actives suitable for that life stage.

Exponent’s Firming Filter CoQ10 Power Serum keeps pure CoQ10 (ubiquinone) fresh in powder form until activation to help preserve potency and antioxidant activity. The powder is activated with Exponent’s Quadruple Hyaluronic Acid Hydrator immediately before use, unlike traditional pre-mixed serums that can gradually lose efficacy over time.

Although CoQ10 (Coenzyme Q10 or ubiquinone) is a powerful anti-aging antioxidant for firming, tightening, and smoothing skin, it is surprisingly underused in modern skincare because it can be difficult to formulate effectively. CoQ10 is highly unstable in traditional water-based skincare formulas and is challenging to deliver at meaningful concentrations without degradation or texture issues. CoQ10 has historically appeared more frequently in Korean skincare and Japanese skincare, where there has long been greater emphasis on preventative aging, skin barrier support, and mitochondrial health rather than aggressive resurfacing alone. Asian beauty formulations have also traditionally been more open to antioxidant-forward and skin-repair-focused ingredients that deliver gradual but visible firming and radiance benefits with lower irritation potential.
