The BIODANCE Pore Tightening Collagen Ampoule is a concentrated serum designed to minimize the appearance of pores and boost skin elasticity. It typically contains a high concentration of collagen to plump the skin and reduce the look of fine lines, along with ingredients that target pore size and control oil production. This ampoule aims to refine skin texture, promote a smoother complexion, and improve overall skin firmness. It's often used as a targeted treatment before moisturizer, particularly for those concerned with enlarged pores and a loss of elasticity.
