Y Theorem Repair Light Serum NAC Y2 (30ml)

A lightweight version of the brand's original reparative serum, this formula uses the NAC Y2 complex—a blend of amino acids and antioxidants—to support cellular regeneration and collagen production. It’s specifically designed for humid climates or oily skin types that need healing benefits without a heavy finish. The gel-like texture absorbs almost instantly, making it a reliable choice for calming redness or post-treatment sensitivity. It’s a high-performance staple that works quietly to strengthen the barrier, especially when layered under a light moisturizer.
