Protective effect of barrier cream

Performance evaluation of barrier creams to showcase their efficacy 24 or 48 hours after application.

In the test, barrier cream is applied to the skin of human volunteers, and its efficacy is evaluated by measuring the transepidermal water loss (TEWL) after controlled irritation via sodium lauryl sulfate (SLS). The cream can be considered effective if the TEWL in the area where the cream is applied is lower than in the control area.

Testing is conducted with 10 or 20 volunteers, and the price of the study depends on the number of volunteers.
