Ampoule vs Serum
Ampoule vs Serum — two concentrated treatment products that are closely related, with an ampoule generally being a more potent, short-term version of a serum. Both deliver targeted actives, but ampoules often contain higher concentrations meant for intensive use during specific periods, while serums suit everyday routines.
Key points
- Ampoules typically carry a higher concentration of active ingredients than standard serums.
- Ampoules are often used as short-term boosters, for example during periods of stress, dryness, or dullness.
- Serums are formulated for regular daily use as a consistent treatment step.
- Both are applied after cleansing and before moisturizer, and the terms are sometimes used interchangeably by brands.
