  • the skin is an organ having fundamental importance to the human organism, as it protects from the external environment, is responsible for each person’s aesthetic appearance and tactile sensations.
  • the skin structure functions as an essential barrier to maintain skin hydration within physiological values.
  • the main factors in this barrier that preside over the maintenance of hydration are: the stratum corneum, epidermal lipids, the Natural Moisturizing Factor (NMF) and the surface hydrolipidic film. These components undergo a continuous renewal process related to the ability of keratinocytes in the epidermis to continuously reproduce and differentiate, thus shaping the various layers that make up the epidermis.
  • NMF Natural Moisturizing Factor
  • the main factors of dehydration are of the chemical type (e.g., the solvent and delipidizing action related to the repeated application of surfactants) or related to unfavorable climatic and environmental conditions: wind, cold and humidity of environments, when intervening separately or jointly, cause dehydration of the stratum corneum with the formation of dry, rough, flaky, cracked skin, redness, itching and other irritative phenomena.
  • dry skin can be caused by endogenous factors of hormonal, dietary and pharmacological origin.
  • endogenous factors of a pharmacological origin The management of the adverse effects related to endogenous factors of a pharmacological origin, is considerably complicated since, the occurrence of skin disorders, often turns out to be a secondary aspect to the patient’s main clinical picture.
  • compositions suitable for the treatment of dry, reddened and cracked skin that are alcohol-based but comprising additives of synthetic origin that do not meet the requirements of tolerability, safety and efficacy needed for the skin of oncology patients.
