Ampoule
Ampoule — a highly concentrated treatment product, often described as a more potent or booster version of a serum. It usually contains a high percentage of active ingredients and is intended for short-term, targeted use to address concerns like dryness, dullness, or the appearance of fatigue, though the term is used loosely across brands.
Key points
- Ampoules are generally marketed as more concentrated than standard serums, though there is no strict industry definition.
- They are often used as a temporary boost during times when skin needs extra support rather than as a permanent routine step.
- Formulas focus on a small number of potent actives, and a few drops are typically enough per application.
- They are applied after cleansing and toning and before moisturizer, similar to a serum.
Frequently asked
What is the difference between an ampoule and a serum?
An ampoule is usually positioned as a more concentrated, intensive version of a serum, but the terms overlap and definitions vary by brand. In practice both are lightweight leave-on treatments applied before moisturizer.
How often should I use an ampoule?
Because they are concentrated, ampoules are often used as a short-term boost or a few times per week, though usage depends on the specific formula. Always follow the product's directions and monitor how your skin reacts.
