How AUTEUR formulates

Key actives

The Formulation

Bio-Reprogramming Peptide

Bioengineered peptide that supports skin regeneration and repair by boosting cellular activity, directly targeting wrinkle formation and quickly diminishing fine lines and wrinkles.

Collagen Amino Acids

Fundamental building blocks that help reinforce the skin’s structural matrix, supporting collagen synthesis and enhancing 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.

Peony Root Extract

Brightening and anti-inflammatory super antioxidant that reduces hyperpigmentation and restores a more even, radiant skin tone.
