The natural slowing of fibroblast activity over time, smoking, smog, alcohol intake, sun exposure and chemical agents can lead to a decrease in the synthesis of young collagen.

Collagen is the main structural protein component of the dermis, and is responsible for the tone, elasticity and firmness of our skin. In young skin not exposed to sunlight, collagen is made up of thickened fibrils arranged in bundles, which are arranged parallel to the skin surface and create an organised "scaffolding" able to give support to the skin; the mature collagen of the skin is demolished by some enzymes (matrix metalloproteinase -MMP) and replaced with young collagen, maintaining a perfect and constant balance, which ensures the renewal of the extracellular matrix of the dermis and prevents the formation of wrinkles.

In adult skin, following the slowdown due to natural causes (loss of natural energy charge) and extrinsic (eg sun) activity of fibroblasts, there is a reduction in the synthesis of new collagen and a thinning of collagen and elastin fibres mature. The existing collagen fibres are arranged in a disorganised manner in the dermis, thus undermining their structural support function; all this is exacerbated by the activity of MMPs, which continue to deteriorate mature collagen fibres without replanting with young collagen. The thinning of the fibres of mature collagen, their disorganisation and their decrease due to the activity of MMP, lead to the sagging of the skin with consequent formation of wrinkles, loss of tone and elasticity.

Prevention and reduction of wrinkles - treatment with

radio-frequency FEEL by Tuenda.


Electromagnetic waves at a frequency of 470 KHz penetrate deeply stimulating the synthesis of collagen.

When electromagnetic waves reach the hypodermis and the dermis, the displacement of ions present in the tissues generate electric currents that, finding the resistance of the invested tissues, are transformed into heat and induce a deep diathermic effect, without affecting the most superficial tissues (epidermis). The increase in the deep temperature of dermis and hypodermis leads to an immediate tensor effect due to the denaturation of mature collagen fibres, followed in 4-6 months, by a stimulating effect of fibroblasts, which produce young collagen, hyaluronic acid and elastin, restoring the skin's supporting structure. FEEL stimulates microcirculation by increasing cell and tissue metabolism, and levels of skin hydration and eliminating toxins and catabolites. The final effect is that of a more toned, more elastic and compact skin and a visible reduction of wrinkles, even in the most advanced stages.
