The MUTHA No. 1 Serum is a clinically tested, do-it-all vitamin C serum that creates healthier skin with ingredients you can trust. Its advanced, potent formula features MUTHALOAD® Core Technology, which includes four molecular weights of Hyaluronic Acid, Niacinamide, and Rice Kefiran.

Our bio-fermented blend allows its clinically-proven, effective ingredients to be absorbed easily and enhance results. TETRAHEXYLDECYL ASCORBATE (THD) — a stabilized form of Vitamin C shown to be 50x more effective than L-Ascorbic Acid — helps reduce pigmentation and increase collagen production. Hyaluronic acid and niacinamide work to hydrate, balance, and protect the skin barrier.

The No. 1 Serum is your complete protecting, hydrating, and repairing treatment.
97% Natural Origin. Dermatologist and Allergy tested. For all skin types, including sensitive skin. Never tested on animals.

Apply 1-2 pumps of the No. 1 Serum in the morning and evening to dry, clean skin on the face, neck, and décolletage. Use the No. 1 Serum by itself or follow with a moisturizer like the MUTHA Face Oil or Cream.
