Rekomendacja kosmetologa

C-Tetra
Medik8 Crystal Retinal 218,89 zł
Opis

C-Tetra® is an advanced antioxidant serum developed by the experts at Medik8, aimed at restoring the skin's natural glow and youthful appearance. The key ingredient is 7% tetrahexyldecyl ascorbate – a stable and effective form of vitamin C that penetrates deeply into the skin layers, providing intense brightening and anti-aging effects.

Vitamin C is known for its strong antioxidant properties, neutralizing free radicals responsible for premature skin aging. Additionally, it stimulates collagen synthesis, leading to increased skin elasticity and reduction of fine lines and wrinkles. Regular use of C-Tetra® helps to even out skin tone, minimizing the visibility of discolorations and giving the skin a healthy, radiant appearance.

The serum formula is enriched with vitamin E, which works synergistically with vitamin C, enhancing its antioxidant effects. Vitamin E also supports skin hydration, preventing dryness and protecting against harmful external factors.

The lightweight, oil-like consistency of C-Tetra® ensures that the product absorbs quickly without leaving a greasy film on the skin. This makes the serum ideal for daily use, both in the morning and evening, serving as an excellent base for makeup. The product is suitable for all skin types, including sensitive skin, due to its gentle yet effective formula.

How to use: After cleansing the skin in the morning, apply 4 drops of C-Tetra® to the face, neck, and décolletage, gently massaging until fully absorbed. Allow it to absorb before applying moisturizer and sunscreen. For best results, use the serum daily as part of your morning skincare routine.

C-Tetra® is not only an effective brightening serum but also a powerful protection against daily environmental stressors. With regular use, the skin becomes more radiant, firm, and resilient to aging processes, resulting in a healthy and youthful appearance.
