Comparison of 12% Ammonium Lactate and 10% Urea Cream in Geriatric With Xerosis Cutis

Comparison of Efficacy and Safety Between Moisturising Cream Containing 12% Ammonium Lactate AND 10% Urea in Geriatric With Xerosis Cutis: Double Blind Randomised Controlled Trial

This study aims to compare the efficacy and safety between moisturizing cream containing 12% ammonium lactate and 10% urea in geriatric with xerosis cutis. A double-blind randomized controlled trial with matching paired subject was conducted on 40 residents of a nursing home in Jakarta. Specified symptom sum score (SRRC), skin capacitance (SCap), transepidermal water loss (TEWL), and side effects were measured at baseline, week-2 and week-4 after therapy, and week-5 one week after therapy cessation. After a week of preconditioning, each subject received two different moisturizing creams to be applied on separate lower limbs.

Dry skin or xerosis cutis is widely known skin health issue in geriatric population with prevalence rate ranges between 29.5 - 85.5%. One of the internal etiological factors is decreased production of natural moisturizing factor as a humectant. Application of moisturizer is the mainstay treatment. Moisturizer with humectant property, like lactate and urea, could restore skin hydration and barrier dysfunction. This study aims to compare the efficacy and safety between moisturizing cream containing 12% ammonium lactate and 10% urea in geriatric with xerosis cutis.
