This powerful retinol cream has skin-renewing properties with optimally concentrated encapsulated Retinol for maximum results.

Retinol is widely recognized as a very effective vitamin in anti-aging treatments, particularly due to its ability to stimulate collagen production, accelerate cell mitosis and normalized the keratinization of the skin.

Regular application dramatically improves skin elasticity, smoothness and smoothness, resulting in younger, clearer and healthier looking skin. However, Retinol is extremely sensitive to oxidation, degradation in air, sunlight, acidic conditions, and heavy metals, which can lead to diminished effectiveness and discoloration of the formula.

Tagra Biotechnology lab overcomes these challenges with the CelluCap™️ R. By delivering Pure retinol stabilized in microencapsulation, Tagra helps us improve the final performance of the formula as well as its longevity.

CellUCap™️ R Encapsulated Retinol is quickly released under mechanical pressure, such as friction. The single-layer polymeric shell crumbles and disintegrates into invisible particles but retains its properties and you continue to enjoy it regardless. Until the product is applied, Retinol remains fresh and powerful.

This state-of-the-art combination of Encapsulated Retinol, Ceramide Complex and the amazing new 4D Hyaluronic Acid encourages the skin's renewal process with a disconcerting efficiency.

It improves skin tone and texture, supports collagen production, and reduces the appearance of fine lines and wrinkles to create a radiant, fit-looking complexion.

A dose of AZULENE minimizes redness and irritation and lessens the effects of Retinol.

GKL40™️ - is a proprietary blend of self-emulsifying fluid silicones. Emollient; the solution smoothes dry skin and conceals wrinkles.

Ceramide Complex GKL42™️ is a multi-lamellar formula composed of vegetable derivative, semi-synthetic ceramides, cholesterol, fatty acid and Phyto-sphingosine. Being identical to lipids found in the skin, the complex has been concentrated and formulated into a structure designed to improve skin hydration and protection. Ceramide Complex restores the protective epidermal barrier and provides enhanced skin lipid delivery and exchange.

4D Hyaluronic Acid is a viscous solution made up of four types of HA with different properties. 4D Hyaluronic Acid builds up and forms a 3D network to precisely target different skin layers, locking in moisture from the outside and retaining it to improve elasticity.
1. Sodium Hyaluronate Cross-Polymer forms a dense protective film on the skin's surface, reducing water loss from within while providing 24-hour hydration and anti-pollution/anti-UV capabilities.
2. Sodium Hyaluronate retains water on the surface of the skin and nourishes the cornea.
3. Acetylated Sodium Hyaluronate firmly adheres to the stratum corneum, ensuring optimal hydration and repairing damaged stratum corneum.
4. Hydrolyzed Sodium Hyaluronate quickly penetrates the epidermis and dermis, hydrating and restoring the skin from within.
