Korean collagen supplements never piqued my interest until I noticed how weak and brittle my nails had become. I could no longer open a can of Coke without my fragile tips breaking or hurting with every slight bend. Giving up my beloved gel manis and using various strengthening treatments helped a bit, but I needed something that could strengthen my nails from within. A quick Google search led me to a facet of K-beauty that I had yet to dive into.

So, what makes them different from the collagen supplements we find in Western markets? Eunice Park, MD, a double board-certified facial and reconstructive surgeon and founder of aesthetic spa Airem, explains that they often combine hydrolyzed marine collagen with skin-boosting ingredients like hyaluronic acid, vitamin C, ceramides, and herbal extracts. They usually come in fun flavors and easy-to-digest formats (like gummies, ampoules, and coffee mixes).
