Kind of evidence
Human trial 2019 · 24 people · adults (91.7% female, mean age ~55) with mild-to-moderate senile xerosis · PMID 31585489

Who was studied
24 adults (91.7% female, mean age ~55) with mild-to-moderate senile xerosis
Sample size
24
Measured outcome
In adults with mild-to-moderate xerosis (senile xerosis), a cream containing ceramides 1, 3, 6-II improved stratum corneum hydration, transepidermal water loss and skin pH more than a hydrophilic cream, measured at 24 hours and after 28 days of twice-daily use.
Certainty
Moderate
Who was measured
Leave-on moisturizers for dry skin. The study enrolled adults with mild-to-moderate xerosis.
Study limits
Small single-site study (24 participants), split-site comparison on the shins, 28 days. It shows the tested formula outperformed a basic hydrophilic cream on measured skin parameters.

    The Effectiveness and Safety of a Skin Care Product With Centella asiatica Leaf Extract, Ceramide NP, and Panthenol in Subjects With Sensitive Skin: A Prospective, Observational Study

    In 88 women with sensitive skin, a face cream containing Centella asiatica leaf extract, ceramide NP and panthenol lowered the SS-10 symptom score by 66% at week 2 and 76% at week 4, with irritation, tautness, itching and redness all significantly reduced.

    Monocentric, Vehicle-Controlled, Double-Blind Study to Assess the Short- and Long-Term Effects of a Ceramide NP C15-Containing Emollient on the Skin Microbiome and the Skin Barrier Function in Sensitive Skin

    In a randomized, double-blind, vehicle-controlled split-body trial of 50 people with sensitive skin, an emollient containing Ceramide NP C15 significantly reduced transepidermal water loss in participants with an impaired skin barrier over 6 weeks.

    Human trial · 2026 · 50 people · people with sensitive skin · People with sensitive skin applying the emollient in a split-body design for 6 weeks; the barrier improvement was clearest in those whose barrier was already impaired. · Exploratory; both the ceramide formulation and the vehicle improved subjective symptoms, and the significant TEWL reduction was seen specifically in the impaired-barrier subgroup.

    Efficacy of ceramides and niacinamide-containing moisturizer versus hydrophilic cream in combination with topical anti-acne treatment in mild to moderate acne vulgaris: A split face, double-blinded, randomized controlled trial

    In 40 people with mild-to-moderate acne all using topical benzoyl peroxide plus adapalene, a moisturiser with ceramides and niacinamide significantly improved non-inflammatory, inflammatory and total acne lesions on that side of the face versus a hydrophilic cream after 8 weeks, and decreased cutaneous irritation.

    Glycerol and the skin: holistic approach to its origin and functions

    Topical glycerol improves stratum corneum hydration, barrier function and skin mechanical properties. The review also reports reduced irritation response and faster wound healing, and traces the effect to aquaporin-3 transport and to glycerol's own presence in the skin.
