Our verdict
These serums do genuinely different jobs, so match it to your concern. The Triple Collagen serum is the gentle hydrator, built on three collagen types for a plumper, softer, more cushioned feel, and it suits almost everyone as a daily layer. The TXA and Niacinamide 15% Glow serum is the active-brightening option, using tranexamic acid and a high dose of niacinamide to target dullness, uneven tone and post-blemish marks over time. If your skin is happy and you mainly want hydration and a smoother base, the Triple Collagen is the easy, low-risk pick. If your goal is a brighter, more even complexion and you tolerate actives, the TXA and Niacinamide serum is the more results-driven choice. They also layer well together: hydrate with the collagen, treat with the TXA serum, and always follow with sunscreen by day.
