How AUTEUR formulates

Key actives

The Formulation

Encapsulated Retinol

Otherwise known as Vitamin A, which delivers the benefits of Retinol with enhanced stability and reduced irritation, accelerating cell turnover and collagen synthesis for a visibly refined texture.

Bakuchiol

Plant-derived alternative to retinol that enhances collagen synthesis, smooths fine lines, and evens tone—without irritation or photosensitivity.

Kahai Oil

Rich in natural retinol, vitamins, and fatty acids to support elasticity and visibly smooth the skin.

Arginine Ferulate

Strengthens skin resilience, calms visible irritation, and defends against environmental stressors for a smoother, more balanced complexion.

Glycolic Acid

Gently exfoliates to refine texture, brighten skin tone, and promote cellular renewal for a smoother, more radiant complexion.

Ceramide Complex

Skin-identical blend of ceramides I, II, III, IV, and VI that reinforces the skin barrier, preventing moisture loss while enhancing elasticity and resilience.

Hyaluronic Complex

Multi-molecular blend of five micro-low to high molecular weights of hyaluronic acid, providing deep, long-lasting hydration while supporting skin elasticity.
