Ageless Beauty 24-Hours Serum. The serums of truth.






Delicate Areas


Physiological changes

Skin ageing is a very complex and irreversible event, the structure of the skin changes as time goes by, the physiological changes lead to loss of elasticity and hydration, the appearance of wrinkles and blemishes.

This process can be divided into two main categories: intrinsic ageing and ageing affected by environmental factors (also called photo-ageing).

From a physiological point of view, both intrinsic ageing and photo-ageing have several aspects in common, mainly represented by the degradation of hyaluronic acid, a naturally-occurring sugar molecule widely present in the skin, where it regulates natural cell turnover and, more deeply, in the dermis, where it contributes to maintaining its microarchitecture.


Hyaluronic acid

Hyaluronic acid is a unique molecule with unique prerogatives, which keeps collagen young, more elastic and extensible and, thanks to its molecular structure, it is able to bind significant quantities of water.

Its physiological action therefore determines a plumping, redensifying and obviously moisturising effect; ultimately, young and elastic skin.

Hyaluronic acid Technosophy

FILLAST® research laboratories had the intuition that every action aimed at acting on hyaluronic acid had to be something more complex and sophisticated than an elementary integration of the skin with this important natural molecule.
From this intuition comes an original research spirit, a different way of thinking and developing dermofunctional solutions: H.A.T.

What is H.A.T – Hyaluronic Acid Technosophy: it means a new scientific method, an original source of research and development to obtain innovative and articulated solutions able to optimise the action and effectiveness of the products, by acting on the biology of hyaluronic acid; ultimately, maintenance and improvement of the prerogatives of hyaluronic acid in the skin.

From H.A.T. comes the S.S.I. system

Supplementation, Stimulation, Inhibition

Much more than just a hyaluronic acid supplement. FILLAST® represents a precise, articulated and sophisticated action on the biology of this important substance naturally contained in the skin.
As a result of the S.S.I. system, hyaluronic acid becomes an active part in remodelling the aesthetic qualities of the skin.

But what does S.S.I. system mean?

It means supplementation, stimulation and inhibition of the loss of hyaluronic acid in the skin.
S.S.I.: Supplementation, production Stimulation and Inhibition of the degradation of hyaluronic acid: all in one product. Essentiality becomes effective.


Supplementation is obtained by providing the skin with a calibrated and specific mixture of hyaluronic acid of different molecular sizes (degree of polymerisation).

The Stimulation of the physiological and natural production of new hyaluronic acid by the skin, also in old age.

The Inhibition of the degradation and alteration of hyaluronic acid already present in the skin with the aim of making its presence more long-lasting and the physiological action on the skin more substantial.

The functional action of each product based on the S.S.I. system is also amplified and made more evident by the appropriate association of other functional substances, of both natural and biotechnological origin.

Excellent aesthetic results

Thanks to the formulation with a high concentration of functional substances that characterises the entire FILLAST line, using these products daily, even in small quantities, allows you to achieve the desired aesthetic result: livelier, brighter, more toned and elastic skin.
