I tried the STR Vitamin C Ampoule Anti-Ox, and it’s a fantastic addition to my skincare routine. The lightweight, non-sticky formula absorbs quickly and, with 20% Vitamin C, it noticeably brightened my skin and evened out my tone after a few weeks of consistent use. There was a slight tingling at first, so sensitive skin types might want to patch-test. It works best in the morning under sunscreen, offering added protection against environmental stressors. Overall, it’s a great choice for a healthy glow and brighter complexion!
