Introduction: Moisturizers are one of the mainstays of the topical treatment of atopic dermatitis (AD). One of the adverse effects of moisturizers is skin irritation, especially on excoriated AD skin. We compared the potential for irritation of two commercially available moisturizer products for the treatment of AD: a ceramide-based moisturizer (Ceradan Cream; Hyphens Pharma Pte Ltd, Singapore) and a urea 5% moisturizer (Aqurea Lite Cream; ICA Pharma Pte Ltd, Singapore).

Methods: We performed a prospective single-blind randomized controlled study recruiting AD patients aged between 8 and 16 years with symmetrical or near symmetrical scratch marks (excoriations) of at least grade 2 to 3 severity score, according to the Eczema Area and Severity Index (EASI), over bilateral antecubital fossae. Subjects were randomized to receive the ceramide-based moisturizer to either the left or right antecubital fossa or urea 5% cream to the other antecubital fossa. Subjects were asked to grade the immediate skin irritation of both creams on a standard visual analogue scale (VAS) and which cream they would prefer to use as a daily moisturizer. Primary outcome was the mean irritant score of each cream, and secondary outcome was the subjects' preference of either cream as their daily moisturizer.

Results: A total of 42 participants were enrolled with a mean age of 11 years 5 months. The ceramide-based cream had a significantly lower mean VAS score (mean 0.69, SD = 1.63) for irritation compared with urea 5% cream (1.43, SD = 1.64) (p = 0.035). More participants also preferred the ceramide-based cream over urea 5% cream (62% versus 38%) as their daily moisturizer, but this did not reach statistical significance (p = 0.164).

Conclusions: A ceramide-based moisturizer may be considered as a suitable choice for children to minimize irritation from moisturizer treatment for AD.

Article Synopsis
  • Hyaluronic acid (HA) is widely used in moisturizers, but traditional formulas only work on the skin's surface, limiting their rejuvenating effects.
  • A study compared a lotion containing multi-weight HA and antioxidants with a single-weight HA and ceramide lotion, focused on improving facial dryness and fine lines in 70 women aged 25-65 over eight weeks.
  • Results showed that the multi-weight HA lotion significantly improved skin dryness, roughness, and fine lines as early as two weeks, indicating its better penetration and effectiveness compared to the single-weight HA lotion.

Background: We aimed to investigate the effects of 2 ceramide plus natural moisturizing factor-enriched formulations compared to a ceramide-based cream on skin moisturization.

Methods: Two double-blinded comparative studies were conducted, which enrolled 35 (n=29 females, n=6 males) and 33 (n=21 females, n=12 males) participants, respectively. Participants applied ceramide plus natural moisturizer cream or ceramide-based cream (study 1) or applied ceramide plus natural moisturizing factor lotion or ceramide-based cream (study 2) to each of their lower legs for 10 days with a 5-day regression period (no moisturizer applied).

Background: Xerosis negatively impacts the quality of life (QoL) for older adults by producing pruritus (itching), burning or stinging, and an uncomfortable sensation of tightness in the skin. Furthermore, chronic illness and pharmacological therapies could worsen skin health. Severe xerosis can also result in redness or cracking of the skin.
