(05) Hyaluron Serum

An intelligent water gesture that transforms the skin from the first contact. Hyaluron Serum by Prof. Dr. Steinkraus condenses the scientific elegance of TetCode4® into a 2.5% hyaluronic acid concentrate with three molecular sizes, capable of hydrating on the surface, penetrating deeply, and restoring visible elasticity and smoothness. The complexion is smoothed, fine lines are softened, and comfort is established, leaving the skin fresh, vibrant, and perfectly prepared to receive subsequent treatment.

Why it works

• Hyaluronic trifactor: short, medium, and long molecular weight for layered hydration: immediate filling 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 accompanies physiological renewal.
• Intelligent moisturizers: glycerin and pentylene glycol enhance water retention and the feeling of comfort after application.
• Dermal balance: arginine helps optimize the skin environment for sustained hyaluronic performance.

Sensory and clinical benefits

• Immediate and sustained hydration: skin appears plumper, more elastic, and dewy from the first use.
• Texture smoothing: 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 skin, and those prone to imperfections.

How to use

Apply to clean skin after vitamin C serum in the morning or after vitamin A serum at night. Distribute a moderate amount and allow the hyaluronic acid to “sink” into the skin for a few moments before proceeding with cream (Light, Medium, or Rich), foundation, or makeup. In advanced routines, it can also be used between actives to enhance tolerance and achieve a silky finish.

Formulation commitment

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

Elegant technical notes

The combined use of the three molecular weights of hyaluronic acid maximizes multilayer water retention and the immediate “plump” effect. The synergy with vitamin C (AM) and vitamin A (PM) amplifies tone uniformity and texture quality, maintaining a polished sensory experience and superior compatibility even on sensitive skin.
