Abstract: Ultrasonography allows the quantification of dermal density and echogenicity changes during the physiological senescence process. Some active ingredients are able to slow down the tissular degeneration and disorganization process. The purpose of this study was to assess the cutaneous changes induced by the topical use of products containing Viniferol® as active ingredient, using high-frequency ultrasound. The study was performed over 12 weeks and included 80 healthy Caucasian female subjects, aged 22–75 years, divided into two groups: the study group and the control group. The product was applied according to a predetermined protocol. The measurements performed for each subject were: the thickness of the epidermis and dermis (mm), the number of low, medium, and high echogenic pixels, and the number of low echogenic pixels in the upper dermis/number of low echogenic pixels in the lower dermis. All the parameters showed a significant improvement. Ultrasound measurements showed an increase of the mean thickness of the epidermis (P < 0.0001) and dermis (P < 0.0001) following the application of the Viniferol product as compared to the control group. The changes in the dermal echogenicity confirm the efficacy and direct action of Viniferol upon the cutaneous fibroblasts. No side effects related to the treatment were recorded. The study proves the efficacy of this active ingredient in the cutaneous senescence process as well, as the fact that anti-aging prophylaxis should be initiated in the 20–40 year critical age group. This interval involves specific changes in dermal echogenicity that quantify intense molecular, biochemical and structural changes, being thus mostly and highly responsive to the anti-aging therapy.
