To clarify, the PURCELL 24/7 Colostrum Pore Defence Ampoule is an over-the-counter (OTC) cosmetic product, not a medical prescription. In K-beauty, the term "ampoule" simply refers to a highly concentrated serum, and the "24/7" name suggests it's safe for use all day and night.
Here is the full product "prescription" (description and usage guide) based on its clinical formulation:
Product Type: Spray-type Ampoule / Facial Mist.
Primary Purpose: Pore tightening, sebum control, and barrier repair.
Hero Ingredient: 7,500ppm Colostrum (rich in growth factors and antibodies) and Pixcell Biom™ (a proprietary complex of 5 types of probiotics/lactic acid bacteria).
Finish: "Glass Skin" effect—dewy but oil-free and non-sticky.
