COSRX’s new upgraded Vitamin C formula is so good! I absolutely love how hydrating it feels on my skin without leaving behind an oily or greasy feeling. The consistency is perfect—it blends in beautifully, feels lightweight, and gives my skin that fresh, healthy-looking glow. This upgraded formula is definitely a win! ✨🧡 #COSRX #VitaminCSerum #SkincareReview #GlowingSkin #SkincareFavorites @COSRX Official
