(07) Rellenar suero de vitamina C

Rediscover the transformative power of vitamin C with a refill designed to preserve the excellence of your ritual. The (07) Refill Vitamin C Serum by Prof. Dr. Steinkraus replenishes the lyophilized pearls of high-purity L-ascorbic acid, ready to activate just before application. By integrating them with your original activating liquid, you obtain a freshly prepared serum that firms, reorganizes the skin matrix, and reveals an even and radiant tone, true to the standards of high cosmetics.

Why you will love it

• Vitamin C at maximum performance: protective pearls that activate instantly for optimal release and no oxidation, maintaining illuminating power and pro-collagen.
• Intelligent formula architecture: conditioning support and jojoba oil harmonize sensoriality and stability of the active ingredient, preserving its integrity until the moment of use.
• Visible results: firmness, refined texture, and even tone with a healthy glow; ideal for reducing hyperpigmentation and post-imperfection marks.
• Sustainable ritual: refill designed to take advantage of the existing activating liquid, optimizing the usage cycle without compromising the premium experience.

2-component technology

The TetCode4® line addresses the inherent instability of L-ascorbic acid by separating the active (pearls) from the vehicle (activating liquid). By mixing them just before application, a fresh and powerful serum is obtained that acts as a benchmark antioxidant and essential cofactor in collagen biosynthesis, reinforcing the dermal matrix and restoring elasticity.

Main benefits

• Ultimate antioxidant: advanced defense against free radicals and environmental stress.
• Collagen support: firming action and reorganization of the skin structure.
• Illuminating effect: improvement of tone, reduction of spots, and clarity of the complexion.
• Smooth texture: finer and more homogeneous surface, with elegant comfort.

How to use (with Vitamin C serum activating liquid)

• Activation: in the palm, gently crush a pearl and add 2-3 pumps of your activating liquid; mix until completely dissolved.
• Application: spread over face, neck, and décolletage, in the morning and/or evening after cleansing.
• Completion: finish with Hyaluron Serum and the Face Care cream (Light, Medium, or Rich) to enhance hydration and comfort.
• Expert tip: breaking the pearl with your finger before adding the activator facilitates a more homogeneous dissolution.

Suggested routine

In the morning: cleansing → activation and application of Vitamin C → Hyaluron Serum → Face Care cream → sun protection SPF50+. In the evening: alternate with Vitamin A Serum on different days to maximize tolerance and anti-aging synergies.

Ingredients (INCI)

Vitamin C Concentrate – Pearls: Ascorbic Acid, Polyquaternium-10, Simmondsia Chinensis (Jojoba) Seed Oil.

Science and technical notes

The pearls may show slight variations in shape due to vibration during transport without affecting their performance; just crush them and activate according to the instructions. Immediate activation minimizes the degradation of ascorbic acid and ensures effective delivery for superior firmness, uniformity, and luminosity.

Skin types

Suitable for all skin types (normal, dry, combination, oily, sensitive, and mature), including those with hyperpigmentation or post-imperfection marks. Its refined watery profile makes it a high-performance daily booster for a healthy and sophisticated glow.
