This Ageless Active Gel is a unique and powerful skincare solution that significantly improves skin tone, colour and radiance by supporting blood circulation through the use of hesperidin, whilst minimising environmental stressors such as heat, UV radiation and pollution thanks to the use of heat shock proteins (HSPs). HSPs reduce the damage that slows down the synthesis of collagen, elastin and hyaluronic acid, and gently regulate pigmentation changes in the skin. Key active ingredients: Vitamin B3 is also used to significantly improve sebum production. Furthermore, this gel delivers robust antioxidant defense thanks to the addition of L-carnosine, which inhibits glycation and other harmful reactions that lead to skin ageing. L-carnosine also supports homeostasis in the skin, a protective barrier that separates the inside from the outside, shields against environmental influences and maintains healthy bodily function. Achieve the ageless and radiant skin you deserve with Ageless Active Gel, use this serum as a replacement for C-Quence by Environ or instead of Night Repair by Lauder. You will notice the difference immediately.

Best value for money for a scientifically tested eye care product. The most advanced product on the market. Our best-selling eye gel. A powerful gel that nourishes and rejuvenates the eye area. This gel targets moisture levels, collagen formation and organisation, dark circles and fluid retention, as well as the regeneration and thickness of the epidermis. An ideal product for use following dermal fillers and treatments targeting ageing around the eyes. May also be used after eyelid surgery! Tested active ingredients: Ectoin: Enables rapid restoration of protein synthesis and the skin’s defence function. In vivo improvement in wrinkle volume and elasticity. Tests show: more effective and longer-lasting than hyaluronic acid alone Palmitoyl Tripeptide-5: The peptide binds to latent TGF-β and activates the collagen production cascade. Protects the ECM from damage. Tetrapeptide-17 (GEKG): Stimulates ECM biosynthesis, such as hyaluronic acid, collagen and fibronectin, which play a crucial role in skin ageing, healing and regeneration. Swertia chirata extract: This extract has been shown to induce a strong production of growth factors from fat-derived stem cells. It increases the thickness of the epidermis, thereby reducing the appearance of wrinkles. Watermelon fruit extract + apple fruit extract + lentil fruit extract + sodium PCA + lactate: Delivers instant hydration as the membrane becomes more fluid and skin’s moisture levels rise. Encapsulated NAD+ fragments: Catalyse the expression of sirtuins (longevity genes). It has been established that NAD+ has a decisive influence on vital processes, including gene expression, cell cycle progression, insulin secretion, DNA repair, apoptosis and ageing. Ribose: Improves ATP regeneration. Anti-wrinkle effect. Vitamin E: Possesses anti-inflammatory and antioxidant properties. Mixture of cholesterol, ceramides, sphingosines and behenic acid: Activates the skin’s water management. Tripeptide-10-Citrulline: This peptide has demonstrated in vitro efficacy in regulating fibrillogenesis. It controls the higher-order matrix and stimulates the formation of well-structured, supple and resilient skin. Vitamin K-Oxide: Accelerates the healing process and helps reduce the severity of bruising following non-surgical and surgical procedures. Reduces dark circles and lymphatic fluid accumulation under the eyes. This is what Prof. Dr Markus Depfenhart has to say about the product: "The thin skin around the eye area quickly shows fine lines due to dehydration, and so a rich blend of moisturisers forms the basis of this gel. Furthermore, the dermal matrix has two objectives: protection against degradation and the synthesis of new structural proteins such as collagen, fibronectin and hyaluronic acid. The activation of latent TGF-β has powerful regenerative effects. NAD+ fragments are used to activate sirtuins – which are involved in gene silencing, apoptosis, fatty acid metabolism and the regulation of cell lifespan. Collagen stimulation should be controlled through proper folding and assembly. A decorin-based peptide stimulates and supports the reconstruction of the collagen structure. The appearance of under-eye bags and dark circles is treated with vitamin K oxide. Applied just once a day, the eye gel has a visible and long-lasting effect in just a few days."

The best care for dry skin The ultimate moisturiser, providing barrier-forming lipids, fatty acids, ceramides and cholesterol. Unlike DELTA Daily Hydration, the Rich Daily Hydration texture is formulated for combination and oily skin, and, above all, for mature skin. This moisturiser enhances the skin’s ability to synthesise molecules essential for moisture balance. Directions for use: Massage in twice daily. When using serums from the Renewal range, the moisturiser should be applied over the serum. The DELTA approach:The skin’s moisture and hydration levels are depleted by a variety of environmental and genetic factors. Increasing the skin’s water content and reducing water loss are the primary objectives of moisturisers. For this reason, fatty acids, cholesterol and ceramides are supplied, and the calcium gradient is regulated. Occlusivity is provided to reduce transepidermal water loss and form a barrier against pollution. The skin’s innate water-retaining capacity is enhanced by contributing to the NMF, glycerine content and increased hyaluronic acid production. Aquaporin channels are a key focus, as they facilitate transport through the epidermis. This moisturiser has been developed to improve the skin’s suppleness and elasticity, radiance, tone and brightness, and to reduce the appearance of fine lines. SAVINGS TIP: With DELTA, you never need a TONER, as the micronised particles (not nano) penetrate the skin easily. Even a single application is sufficient for this product on normal skin.
