Ampoules are super-charged serums with higher concentrations of active ingredients designed for one-time use. They often feature one main active ingredient, and the ampoule form is designed to preserve the purity and potency of the product. Ampoules are known for their concentrated formulas and, more importantly, their efficacy. The serums used in ampoules generally use minimalist formulas, focusing on specific ingredients and ingredient combinations to provide your skin with targeted care. Ampoules are proving to deliver near medical-grade results without the downtime.
