To be able to determine the potency of Dr. Kinsella Eye Serum, a study needed to be conducted that could prove the efficacy of decreasing the eye bags volume, improving the dark circles and decreasing the wrinkles depth, in this eye serum. A blinded randomised clinical study was planned for the evaluation of the Dr. Kinsella Eye Serum in decreasing the eye bags’ volume With this clinical study, we aimed to assess four crucial goals:

To perform this study, one group of 22 healthy female subjects between 35 years old and 60 years old, presenting under eyes puffiness and dark circles, and visible wrinkles on the crows feet area are enrolled the investigational product (eye serum) is applied with the ring fingers fingertips over the cleansed skin around the eye contour area, including the under eye area and the crows feet area, twice a day, at mornings and at evenings, during 28 consecutive days.

Wrinkle reduction

Wrinkles depth mean results obtained before and after 28 days of consecutive application of the investigational product eye serum.

After 28 days of the investigational product Dr. Kinsella Eye Serum, a mean decrease of 5 91 µm in the wrinkles depth was observed; decreasing for the subjects with a mean decrease of 18% – 41% among these subjects and with a maximum decrease of 41% – 51%.

Wrinkle depth study
