Auteur's Superlative Serum PHI is an a-hydrating serum targeting expression lines while restoring multi-level hydration within the skin. Powered by advanced neuropeptide technology, it works to visibly smooth and improve lines and wrinkles and support improved skin density. Experience both surface refinement and sustained structural support, helping skin appear smoother and more even. Peptides, including advanced neurotransmitter inhibitors, help reduce the appearance of expression lines within minutes while supporting collagen organization over time. A multi-layered hydration system restores bounce and elasticity, leaving skin visibly smoother, plumper, and more resilient. ACTIVE INGREDIENTS Bio-Reprogramming Peptide: neurotransmitter peptide reducing expression lines within 15 minutes of application and supporting skin regeneration for comprehensive improvements in the appearance of wrinkles. Collagen Amino Acids: Fundamental building blocks that help reinforce the skin’s structure, supporting collagen synthesis and enhancing the skin’s ability to recover, regenerate, and retain its natural firmness. Re-Gen Polypeptide: Biomimetic collagen booster that stimulates type I and III collagen synthesis, reinforcing the extracellular matrix for reduced fine lines and firmer, smoother, more resilient skin. Hydrolysed Hyaluronic Acid: Multi-molecular hydration complex to plump, smooth, and fortify the skin’s barrier, minimizing moisture loss.
