Product details

Auteur approaches wrinkle care with a multi-dimensional strategy—tightening, smoothing, and reinforcing the skin’s architecture from the inside out. This potent formula is engineered for both immediate results and long-term structural renewal.


At the surface, advanced peptides relax micro-muscular contractions to soften visible expression lines, delivering a firmer, more lifted appearance. Beneath, the formula helps stimulate collagen synthesis and support the skin’s extracellular matrix to minimize future wrinkle formation.


Daily use enhances skin’s resilience, hydration, and tone. Hydrating actives replenish moisture throughout all layers of the skin, while antioxidants defend against oxidative stress, helping to repair visible signs of aging and restore balance to compromised skin. With regular application, skin looks noticeably smoother, tighter, and more refined—especially across high-movement zones like the forehead, crow’s feet, and nasolabial folds.


INSIDE THE FORMULA

  • SYN®-AKE Peptide: Potent neurotransmitter-inhibiting peptide that relaxes wrinkle depth and delivers an immediate tightening effect.
  • Hyaluronic Complex: Delivers multi-weight hydration throughout the layers of the skin to plump and smooth fine lines.
  • Resveratrol: A powerful antioxidant that neutralizes free radicals, supports DNA repair, and protects against future damage.


VISIBLE RESULTS

  • Instantly tightens and smooths expression lines
  • Reduces the appearance of deep-set wrinkles over time
  • Hydrates and plumps the skin for a more refined texture
  • Improves skin firmness and visible contour definition
  • Defends against oxidative damage and premature aging
how to use

Apply only to clean, dry skin. If using an oil-based cleanser, double-cleanse with the Definitive Enzyme Cleanser to remove all residue.

Morning use: Tap a small amount onto expression lines and around the eyes for a visibly tighter, smoother finish.

Evening use: Apply 2 pumps across the face, neck, and décolleté in an upward motion. Allow to absorb fully before applying other products.

For best results, apply prior to any creams or serums. Avoid use with products high in silicones or oils, which may interfere with absorption.
