Abstract
OBJECTIVE: Baby skin differs significantly from adult skin and requires special care. The Cussons Baby Sensicare Range (Sensicare) of products has been specifically formulated for baby skin and a range of standard cosmetic clinical tests were conducted in adult females with dry skin to evaluate the effectiveness of the range on skin moisturization and barrier function. METHODS: The studies were within subject, controlled, single blind studies. For the Sensicare Body Wash skin moisturization (Corneometer) was measured before application and after 7 and 14 days of twice daily use. For the Sensicare Moisturizing Lotion and Sensicare Soothing Cream skin moisturization was measured before application and at 2, 4, 6, 8 and 24 hours after a single application; skin elasticity (Cutometer) and transepidermal water loss (TEWL, Tewameter) were assessed before and after 14 days of twice daily use; and skin erythema (Mexameter) before induction with sodium lauryl sulphate (SLS), and at 30 mins, 24 and 48 hours after patch removal. Changes from baseline and changes versus control were evaluated. RESULTS: Thirty to thirty-five subjects completed each study. Skin moisture content was significantly increased from baseline for all Cussons Baby Sensicare Products (p < 0.05 for Hair & Body Wash; and p < 0.001 for Cream & Lotion). Changes from baseline in skin elasticity were significantly superior to control (unperfumed liquid soap) after 14 days twice daily use of the Lotion, and Cream (p < 0.05). There were no significant changes from baseline or significant differences from control in TEWL for the Lotion, or Cream. The increases in the average skin erythema index were significantly smaller for the Lotion, and Cream 30 minutes following SLS patch removal (p < 0.05 v sterile water, p < 0.001 v no treatment for both products). All the Sensicare products were well tolerated. CONCLUSION: These studies support the use of the Cussons Baby Sensicare range of products for new born, sensitive and eczema prone skin.

Summary
There are a number of key differences between newborn and adult skin which necessitate special care. There are differences in skin pH; at birth the pH of the skin is >6.0 but following birth the acid mantle develops. Through disturbance of the epidermal barrier infant skin can become drier (there is greater transepidermal water loss in infants) and more prone to damage by allowing allergens and microbes to reach the dermis [2]. This can lead to inflammation characteristic of atopic dermatitis [3]. It is important only to use skin care products on baby skin that, at least, maintain skin integrity, barrier function and protect against harmful agents
