It is one of the fundamental components of connective tissues and gives the skin resistance and shape retention. It is a component of the extracellular matrix and is self-produced by our body with the aim of hydrating and protecting the tissues. Its lack causes a weakening of the skin which promotes the formation of imperfections and wrinkles. Its concentration in the tissues of the body tends to decrease with age.

The hyaluronic acid contained in 5 HA Serum, therefore, acts precisely against the signs of aging, which are generally early evident in the eye contour area. Also excellent as a moisturizing agent, it helps fight the effects of climatic changes, acting as a protection against wind, cold, dry and sunny climate.

The high molecular weight hyaluronic acid contained in this product acts on the surface, ensuring effective hydration, and has a film-forming action, binding to the stratum corneum with a tensor and protective effect.

Low molecular weight hyaluronic acid, on the other hand, acts in depth, penetrating and stimulating the physiological production of proteins responsible for skin firmness and elasticity, and reducing the depth of wrinkles. Studies carried out with low molecular weight hyaluronic acid reveal, after 8 weeks, an increase in skin elasticity, increased skin hydration, deep reduction of wrinkles.

The powder content, once hydrated, returns a neutral PH gel, without the addition of thickeners or gelling agents.


Aloe has been considered a magical plant with infinite properties for centuries. For Cleopatra, the use of Aloe, associated with milk baths, was prodigious for its beauty. The ancient Romans exploited Aloe for its healing properties, so much so that it was used in the form of a balm to treat soldiers' war wounds. Hence, Aloe becomes an important soothing, healing and smoothing product, particularly suitable for beauty treatments for the skin. In addition to having an anti-aging power, it also acts directly against irritation and therefore against the inflammatory states of the same.


A real cure-all for the skin. It improves blood circulation and protects the capillaries. Its properties are several:

Soothing: suitable for red and irritated skin;

Toning and astringent: suitable for rebalancing the skin on oily skin, it reduces the visibility of the pores with an astringent effect;

Anti-couperose and restorative vessel: performs a restorative action on blood vessels;

Antiseptic and purifying: reduces blackheads, dilated pores and pimples.


Excellent remedy for mature, dull and dehydrated skin, it stimulates the production of Collagen and Elastin, thus helping to keep the skin elastic. Furthermore, the healing power of mimosa acts against skin imperfections, favoring a skin with a uniform color.


Hydrolyzed collagen is obtained by subjecting native type I collagen to thermal, acid, alkaline and / or enzymatic hydrolysis processes, with the aim of reducing it into protein fragments of lower molecular weight. Breaking down the native collagen into a certain number of peptide chains, more or less long, has the purpose of enhancing or breaking down its gelling power, promoting digestion and food absorption, and allowing - in case of topical application (cosmetics) - the cutaneous absorption of the peptide chains that compose it.


Collagen is responsible for the structure of the skin and is the first to be affected by the passage of time and the incidence of environmental factors, contributing to the degradation of the Collagen itself and therefore the onset of wrinkles, as it is the protein that anchors the tissues between them and is responsible for the tone and firmness of the skin.

Foods containing sugars damage not only the silhouette, but also Collagen, due to the phenomenon of glycation, or the bond between sugars and proteins, which gives life to molecules called AGE, with consequent damage to the same Collagen and Elastin fibers. Inadequate sun exposure is an equally important cause of collagen loss.

The maintenance of Collagen is therefore an important goal for the health and youth of the skin. If not conveyed through specific active ingredients, this would stop at the superficial level of the skin: this is why KetozonaTM cosmetics intervenes with active ingredients capable of transporting it and stimulating its natural synthesis.


Green Tea is important in the anti-aging action thanks to its precious antioxidant content, which helps the body to defend itself from free radicals (reactive molecules involved in cell damage).

Epigallocatechinagallato aside, the mixture of the various substances present in Green Tea has demonstrated a superior antioxidant action compared to the individual components, confirming the now accepted thesis that dietary phytocomplexes are much more active than the individual isolated and purified components.


Hops are part of the hemp family, and are native to Central Europe. It is traditionally used as an adjunct in the healing of wounds and skin inflammations, but it also acts as a stimulant of collagen production and is therefore also ideal for dry and mature skin.


Vitamin E, or Tocopherol, is a fat-soluble Vitamin, that is, soluble in fats and oils. The primary role of Vitamin E is to protect the body's tissues from oxidation and free radicals. It therefore acts as an excellent anti-aging remedy.
