(05) Hyaluron Serum

A smart water gesture that transforms skin from the very first contact. Hyaluron Serum by Prof. Dr. Steinkraus condenses the scientific elegance of TetCode4® into a hyaluronic acid concentrate at 2.5% with three molecular sizes, able to hydrate on the surface, penetrate deeply and restore visible elasticity and smoothness. The complexion smooths out, fine lines soften and comfort sets in, leaving skin fresh, vibrant and perfectly prepared to receive the following treatment.

Why it works

• Hyaluronic trifactor: short, medium and long molecular weight for layered hydration: immediate plumping effect on the surface, water deposit in deeper layers and improved elasticity over time.
• TetCode4® botanical architecture: heather (Calluna vulgaris) rich in protective polyphenols and rye (Secale cereale) with a gentle astringent action that supports physiological renewal.
• Smart humectants: glycerin and pentylene glycol reinforce water retention and the feeling of comfort after application.
• Dermal balance: arginine helps optimize the skin's environment for sustained hyaluronic performance.

Sensorial and clinical benefits

• Immediate and sustained hydration: plumper, more elastic and dewy skin from the very first use.
• Smoother texture: improves the appearance of fine lines and provides even luminosity.
• Strengthened barrier: comfort without tightness and greater resilience against environmental stress.
• High compatibility: suitable for normal, dry, combination, oily, sensitive, mature and blemish-prone skin.

How to use

Apply to clean skin after the vitamin C serum in the morning or after the vitamin A serum at night. Spread a moderate amount and let the hyaluronic acid "anchor" to the skin for a few moments before continuing with the cream (Light, Medium or Rich), primer or makeup. In advanced routines, it can also be used between actives to enhance tolerance and the silky finish.

Formulation commitment

• Vegan and unisex: universal design with high tolerance.
• Free from PEGs, silicones, microplastics, acrylates and parabens: a refined and exquisitely balanced formula.

Elegant technical notes

The combined use of the three hyaluronic molecular weights maximizes multi-layer water retention and the immediate "plump" effect. The synergy with vitamin C (AM) and vitamin A (PM) amplifies tone evenness and texture quality, maintaining a polished sensoriality and superior compatibility even on sensitive skin.
