The liquid carries a faint orange-yellow cast and sits thin on the skin; two or three drops cover the whole face. Once spread it leaves a smooth finish and you can move straight to the next step.

【Nano-processed, so it travels further】
To make the ingredient easier for the skin to take up, the brand nano-processes the coenzyme Q10 so it reaches every corner of the stratum corneum. That is the technical point of this bottle.

【Tightened, then glossy】
The direction is a tightened feel with a gloss on top. Age-appropriate care, as used here, means daily care suited to your age, within what a cosmetic does.

【Positioned as a moisturising ingredient】
The coenzyme Q10 in the formula is ubiquinone, and in this serum it is positioned as a moisturising ingredient. The brand describes it as something healthy skin cannot do without.

【The formula contains alcohol】
Ethanol appears on the ingredient list. If alcohol is a concern for you, read the list before deciding.

Suitable for: anyone noticing signs of age; anyone concerned with firmness and gloss; anyone who wants one more serum in an existing routine.

How to use: after cleansing and toner, smooth two to three drops over the face, then finish with emulsion or cream.

Patch-test on the inner arm before first use. If redness, itching or stinging occurs, stop use and consult a dermatologist.
