The thermal water, the key element of the line, flows inside the pools of the Hotel Saturno Fonte Pura, which, in collaboration with the University of Pavia, has conducted a study on the efficacy of the thermal waters that flow in the territory of the municipality of Manciano as an adjuvant in dermatological pathologies and in particular in cases of Psoriasis.

In 2016, the Ministry of Health recognised the therapeutic properties of these thermal waters, in particular, in dermatological pathologies. From the synergy of the thermal waters with vegetable oils and natural essential oils come the products of the Soin Saturnia line, capable of promoting cellular rejuvenation, for healthy, radiant skin.

The benefits of the thermal waters that flow naturally in the municipality of Manciano have been well known since ancient times: they were appreciated by the Etruscans and the Romans; in the 18th and 19th centuries the waters were considered particularly prodigious for curing skin diseases. In the early 1900s, clinical analyses were conducted that scientifically demonstrated their benefits. Soin Saturnia was born from the desire to 'transfer' the certified efficacy of the thermal waters into a totally natural cosmetic line.
