Cetaphil Intensive Moisturising Cream 85g. Dry skin conditions are caused by lack of moisture in the skin’s outer layer. This lack of moisture is due to the “protective barrier” being compromised, which allows moisture to escape. In normal skin, the barrier function is intact and unbroken, thereby retaining moisture and keeping skin soft and supple. Shea Butter is a natural ingredient from the Karite tree of Africa, known for its pleasant moisturising properties. Moisturizer is suitable for very dry hands, feet, elbows and knees.
