Concerns / Skin Barrier Damage

Skin Barrier Damage

Disruption of the stratum corneum leading to increased transepidermal water loss and sensitivity. A common underlying factor in many skin concerns.

Animal StudyResults in animals only. May or may not translate to humans.CeramidesPublished: March 7, 2026

MDBA May Help Alleviate Atopic Dermatitis Symptoms

Researchers studied a combination of four ingredients called MDBA to see if it could help alleviate symptoms of atopic dermatitis, a condition that affects the skin's barrier and immune system. In lab experiments and animal studies, MDBA showed promise in reducing inflammation and improving skin barrier function. However, more research is needed to confirm these findings.

Why it matters: Understanding how MDBA works could lead to new treatments for atopic dermatitis, a condition that affects millions of people worldwide.

This study was conducted in lab experiments and animal models, and its findings may not translate to humans. Further research is needed to confirm the efficacy and safety of MDBA in people with atopic dermatitis.

Ceramides with longer acyl chains may improve skin barrier function

Researchers studied how different lengths of ceramide molecules affect human skin barrier recovery and hydration. They found that ceramides with longer acyl chains may be more effective at improving skin barrier function. However, more research is needed to confirm these findings.

Why it matters: Understanding how ceramide acyl chain length affects skin barrier function may lead to better skincare products for improving skin hydration and barrier recovery.

This study had a small sample size and was a controlled trial, but the sample size was not specified. The study only tested two different ceramide formulations, and more research is needed to confirm these findings.

Skin Barrier Damage Linked to Chronic Kidney Disease-Associated Pruritus

Researchers studied the relationship between skin barrier damage and chronic kidney disease-associated pruritus (CKD-aP). They found that CKD-aP may be related to changes in the skin barrier, but more research is needed to understand this connection. The study suggests that repairing the skin barrier could be a potential treatment for CKD-aP.

Why it matters: Understanding the relationship between skin barrier damage and CKD-aP may help improve treatment options for patients with this condition.

This review is based on existing research and does not present new findings. The relationship between skin barrier damage and CKD-aP is complex and not fully understood.

Ceramide-Infused Skin Barrier May Help Reduce Ostomy Complications

Researchers studied a ceramide-infused skin barrier for use after ostomy surgery. They found that it may lower costs and reduce skin complications in patients. However, more research is needed to confirm these findings.

Why it matters: This study may help skincare professionals understand how to improve skin health in patients with ostomies.

Based on a single randomized clinical trial (ADVOCATE) and economic models. Further research is needed to confirm these findings.
