Favourable effect of creams with skimmed donkey milk encapsulated in nanoliposomes on skin physiology.

: The use of donkey milk has a long history in external dermal application for cosmetic and medical purposes. The encapsulation of different drugs into nanoliposomes and nutrients may have many benefits for the delivery of the targeted substance. The aim of the present study is to test creams with nanoliposomes encapsulated with skimmed donkey milk, reported in our registered patent, compared to effect of the placebo cream and the untreated skin. To investigate the effect of formulated cream, we have measured the electrical capacitance, transepidermal water loss and the skin pH value. The study included 15 healthy volunteers (11 women and 4 men). The patented creams exhibited satisfactory moisturizing properties very soon after application, while hydration was reached earlier in the spots treated with night cream. Transepidermal water loss slightly decreased only after four weeks of treatment in each of the spots assessed. The pH value was similar after each of the treatments. Tested creams may enhance the moisture of skin very soon after application, in this way potentially enable deeper permeation of phospholipids and essential proteins, without changing the pH. It may also contribute to additional anti-aging effects. This article is protected by copyright. All rights reserved.
