Every day from the very first day, morning or evening. There is no easing-in period, and no study has ever compared the two times of day.

Where do you apply CoQ10?

All over the face. Keep it away from your eyes and lips.

Does CoQ10 make skin more sensitive to the sun?

No. CoQ10 is not flagged as increasing sun sensitivity.

No. No cosmetic regulator in the United States, Canada, the European Union or Great Britain sets a maximum strength for it. That is a limit on the rules, not a signal to use more.

CoQ10 — What It Does & How to Use It

What does CoQ10 do?#

CoQ10 (Coenzyme Q10) is a naturally occurring antioxidant found in your skin. Topically applied, it helps support a more energized, youthful-looking complexion and provides antioxidant support for skin that looks healthy and radiant despite everyday environmental stress.

How it works

CoQ10 is a naturally occurring antioxidant found in your skin. Topically applied, it helps the skin look more energized and provides antioxidant support for skin that looks healthy and radiant despite everyday environmental stress. It complements other antioxidants like vitamin E, helping maintain a more resilient, youthful-looking complexion.

How to use CoQ10#

Every day from the very first day, morning or evening. There is no easing-in period, and no study has ever compared the two times of day.
On clean skin, after anything watery and before your moisturizer. It is an oil-loving ingredient, so it sits better over a hydrating layer than under one.
Across the whole face. It has also been used around the eyes, on the neck and on the backs of the hands, so it is not a face-only step.
Expect it to feel unremarkable. There is no settling-in phase, no flaking stage and no early breakout to ride out — and in testing on skin that reacts easily, and on skin that gets dry and itchy, it caused no stinging or redness at all.
Keep the bottle somewhere cool and out of the light, and close it properly. This one fades in daylight, which is why it usually comes in an opaque or tinted container.
If you use a strong retinoid, apply that on its own and keep this for your other routine of the day.
Wear a daily sunscreen alongside it, as you would with anything for fine lines. It does not make skin burn more easily, but it is also not a substitute for sun protection.
Sits well alongside other antioxidants like vitamin E in the same routine.

Discontinue use if unexpected discomfort occurs.

Who should avoid CoQ10?#

Six situations change whether CoQ10 suits your skin right now. Each one is either a reason to skip it, a reason to go slowly, or nothing to watch for.

Fragile or Sensitive: Go slowly
Recent Facial or Laser: Go slowly
Maternity & Nursing: No caution
Prone to Redness: No caution
Dry or Itchy Patches: No caution
Recent Shave or Wax: No caution

Fragile or Sensitive — Use it less often — or stop — if it feels uncomfortable, and keep it off skin that’s broken, cut or sunburned.

Recent Facial or Laser — Wait until your skin feels settled before reintroducing — typically 7 to 14 days after a facial or laser appointment.

Cosmetic strength limits for CoQ10 where you live#

Region	Maximum strength
United States	No explicit cap
Canada	No explicit cap
European Union	No explicit cap
Great Britain	No explicit cap

No cosmetic regulator in these four markets sets a maximum strength for coq10. That is a limit on the rules, not a signal to use more: how much goes into a product is the formulator's decision.
