This TonyMoly Inkey Library ampoule is the Collagen variant of the brand's Inkey Library line, formulated to support firmness and elasticity in the skin. It features yeast-fermented collagen intended to help visibly reduce the look of fine lines and improve skin bounce over time, paired with soothing and hydrating supporting ingredients typical of the range such as panthenol and hyaluronic acid. The lightweight ampoule texture absorbs readily into skin, making it suitable for layering under moisturizer as part of a daily routine. It's a good fit for those starting to notice loss of firmness or early signs of aging and want an accessible entry point into ampoule-based Korean skincare. Apply a few drops onto cleansed skin, morning and night, before your moisturizer.
