Chapter One Sérum

All-Day Renewal & Radiance

Chapter One Serum is designed for all-day skin renewal. Working in harmony with your skin’s natural rhythm, it delivers deep nourishment and helps to relieve signs of fatigue built up throughout the day — so you can wake up with radiant skin. This highly concentrated formula features a golden ratio of Bi-Collagen Complex and Dual-HA (Hyaluronic Acid) to enhance hydration, strengthen the skin’s structural integrity, and restore elasticity from within. It’s infused with sakura extract and vitamin C to brighten skin tone, reduce dullness, and minimize pigmentation. Vitamin E and Dipotassium Glycyrrhizate provide antioxidant protection and calming care, helping to reinforce your skin’s natural barrier. Gentle enough for both day and night, Chapter One Serum works best when paired with Chapter One Day Gel SPF35 — creating a continuous cycle of hydration, protection, and renewal.
