Clinical Trial Summary

Skin moisturizing and elasticizing efficacy of an amino acid food supplement

Description:

Primary end point of this study was to evaluate the moisturizing and elasticizing activity of "Nutrakos®" Amino Acid Food Supplement, both photoexposed and not photoexposed on skin areas (forearm volar and dorsal surface) by non-invasive instrumental measurements; the product will be tested for 1 month by female subjects, aged 35-70 years with skin photoaging. An additional aim of this study was to evaluate the product tolerance both by investigator and volunteers.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change from baseline of superficial skin hydration	Skin electrical capacitance value was measured mono-laterally on the right or left forearm (volar and dorsal surface) with Corneometer CM825 (Courage - Khazaka, Köln, Germany). The measure of the skin capacitance properties is an indirect expression of its hydration level.	Basal visit (T0), 2 weeks (T2W), 1 month (T1M)
Primary	Change from baseline of deep skin hydration	Tissue dielectric constant value of superficial and deep skin layers was measured mono-laterally on the right or left forearm (volar and dorsal surface) with MoistureMeterD (Delfin Technologies, Kuopio - Finland)	Basal visit (T0), 2 weeks (T2W), 1 month (T1M)
Primary	Change from baseline of skin plastoelasticity	Superficial and deep skin plastoelasticity were measured mono-laterally on the right or left forearm (volar and dorsal surface) with the instrument Dermal Torque Meter (Dia-Stron Ltd., UK).	Basal visit (T0), 2 weeks (T2W), 1 month (T1M)
Secondary	Change from baseline of tolerance	The food supplement tolerance was evaluated considering: any adverse event related to the study treatment, which occurred during the study; any judgement reported by the volunteers.	Basal visit (T0), 2 weeks (T2W), 1 month (T1M)
