Ampoule vs Serum- What is the difference?

Ampoule is essentially a more highly concentrated serum. It also usually comes in a one-time-use silk glass capsule.

Therefore, it is usually thicker in consistency and more expensive than serum.

You don’t need ampoule everyday as it may be too much for your skin and cause irritation.

However, ampoules are great for an at home DIY spa facial treatment.
