A Novel Night Moisturizer Enhances Cutaneous Barrier Function in Dry Skin and Improves Dermatological Outcomes in Rosacea-prone Skin.

Objective: We assessed whether Cetaphil Redness Control Night Cream (CRCNC; Galderma Laboratories, Fort Worth, Texas) improves electrical capacitance (EC) and transepidermal water loss (TEWL) in healthy subjects with dry skin and determined efficacy and tolerability in subjects with rosacea. Study design: The present study included two independent, open-label investigations: in the first, EC and TEWL were measured at baseline and at two, four, eight, and 24 hours after one application of CRCNC to dry skin; in the second, an evaluation of once-daily CRCNC application for 22 days using a chromameter, image analysis, and trained rater was performed, with patient evaluations at baseline and Days 1, 8, and 22 collected. The first study enrolled 20 subjects (13 women; mean age: 45 years). The second study enrolled 33 women (mean age: 54 years), with 30 having sensitive skin. Results: EC increased significantly at two (by 67.0%), four (60.2%), eight (52.1%), and 24 (17.9%) hours after CRCNC application. TEWL was reduced significantly at two (18.0%), four (14.3%), and eight (18.2%) hours after application. Additionally, improvements in redness were seen at Days 8 (24.2%; p=0.008) and 22 (27.3%; p=0.004). Versus baseline, 21.2% (p=0.07), 39.4% (p<0.001), and 48.5% (p<0.001) of subjects reported improvements at 30 minutes after application and on Days 8 and 22, respectively. Conclusions: CRCNC is an effective and well-tolerated moisturizer that improves cutaneous barrier function in subjects with dry skin and in those subjects with sensitive skin and type 1 rosacea.
