Why Most Eczema Skincare Products Use the Same Ingredients

How FDA regulation shapes sensitive skincare—and why Korean skincare explores anti-inflammatory and microbiome ingredients.
Caring for sensitive or eczema-prone skin can feel surprisingly complicated. Many people searching for sensitive skincare or products designed for eczema-prone skin quickly notice that many formulas look very similar: the same handful of ingredients, similar claims, and limited variation across brands.
This is not simply a coincidence. In the United States, eczema is regulated as a disease, which means products that claim to treat it must follow strict FDA drug regulations. As a result, many brands rely on the same approved ingredients, while innovation often focuses on supportive skincare—barrier repair, soothing ingredients, and microbiome balance—rather than medical treatment claims.
Understanding how this regulatory structure works helps explain why eczema skincare in the U.S. looks the way it does—and why new approaches inspired by Korean skincare research are beginning to shift how sensitive skin is supported.

Why Is Eczema Classified as a Disease in the U.S.?
Eczema—most commonly referred to as atopic dermatitis—is classified in the United States as a chronic inflammatory skin disease rather than a cosmetic concern.
According to the American Academy of Dermatology, atopic dermatitis involves inflammation, dryness, and a weakened skin barrier that makes the skin more vulnerable to irritation and environmental triggers.

This classification is important because it determines how products designed to address eczema can be formulated and marketed.
When a product claims to treat, prevent, or cure eczema, it is legally considered a drug rather than a cosmetic. That distinction triggers an entirely different regulatory framework.
How Does FDA Regulation Shape Eczema Skincare?
In the United States, the Food and Drug Administration (FDA) regulates cosmetics and drugs under separate legal categories.
Cosmetics—including most skincare products—are intended to cleanse, beautify, or support the appearance of the skin. Drug products, however, are intended to diagnose, treat, mitigate, or prevent disease.
Because eczema is classified as a disease, products claiming to treat it must follow the FDA’s over-the-counter drug monograph system or undergo the much longer process of developing an FDA-approved drug.
This means eczema products marketed with treatment claims typically rely on a limited set of approved active ingredients, such as:
- colloidal oatmeal
- hydrocortisone
- zinc oxide
These ingredients have been studied extensively and are recognized as safe and effective for certain uses.
But the regulatory requirements also create a narrow path for brands that want to develop new approaches to eczema care.
Why Ingredient Innovation Can Be Limited
Developing a new drug ingredient requires years of research, clinical trials, and regulatory approval.
For many skincare brands, this process is simply not practical.
As a result, many eczema products in the U.S. rely on the same few eczema-safe skincare ingredients, repeated across multiple brands and product lines.
This doesn’t necessarily mean those ingredients are ineffective. But it does mean that innovation often happens outside the drug category, within skincare designed to support sensitive or eczema-prone skin without making medical claims.
In these formulations, the focus often shifts to ingredients that help maintain skin comfort and resilience, such as:
- ceramide cream formulations that support barrier repair
- soothing botanical extracts
- microbiome skincare ingredients that support skin balance
- gentle hydration systems designed for sensitive skin
These types of formulations focus on supporting how the skin functions day-to-day rather than treating a disease directly.
The Difference Between Treating Eczema and Supporting Skin
For people with eczema-prone skin, it’s important to understand the distinction between medical treatment and daily skin support.
Medical treatments—including prescription medications or certain over-the-counter drugs—are designed to manage inflammation during active flare-ups.
Supportive skincare, on the other hand, focuses on maintaining the skin’s barrier and helping the skin remain calm and resilient over time.
Dermatology research increasingly recognizes the importance of skin barrier repair in maintaining skin health. When the barrier becomes compromised, moisture escapes more easily and irritants can penetrate the skin more readily.
This is why many dermatologists recommend consistent skincare routines that prioritize hydration and barrier support alongside medical treatment when necessary.

How Does Korean Skincare Approach Atopic Skin?
While the U.S. regulatory system focuses heavily on treatment categories, other regions—particularly Korea—have developed extensive skincare research dedicated to sensitive and atopic skin.
In Korea, atopic skin care is often approached through long-term skin support rather than only flare-up management.
Retail stores commonly dedicate entire sections to products designed specifically for sensitive or eczema-prone skin. These formulations often emphasize:
- barrier repair ingredients
- centella asiatica skincare
- hydration systems that strengthen the skin barrier
- soothing botanical extracts
- microbiome-support ingredients
Instead of focusing only on short-term symptom management, many Korean formulations aim to support the skin consistently so it remains balanced over time.
This philosophy has influenced a growing number of anti-inflammatory skincare approaches globally.
Anti-Inflammatory and Barrier-Repair Ingredients for Sensitive Skin
Because eczema-prone skin often involves inflammation and barrier disruption, many skincare formulations focus on ingredients that support these aspects of skin health.
Some of the most widely used ingredients in soothing skin care include:
Ceramides
Ceramides are lipids naturally found in the skin barrier. They help seal moisture into the skin and prevent dehydration.
In ceramide cream formulations, these lipids help reinforce the skin barrier and improve hydration.
Centella Asiatica
Centella asiatica is a botanical ingredient widely used in Korean skincare.
Often referred to as cica, this plant extract is known for helping calm visible redness and supporting barrier repair in sensitive skin.
Microbiome-Supporting Ingredients
The skin microbiome—the community of microorganisms living on the skin—plays an important role in maintaining balance and protecting against environmental stress.
In microbiome skincare, ingredients such as probiotics or prebiotics are used to help support this ecosystem.
Research continues to explore how microbiome balance influences skin inflammation and immune responses. Studies suggest that microbial imbalances can contribute to inflammatory signaling in the skin, highlighting the importance of maintaining a healthy skin environment.

How Treats Lab Approaches Eczema-Prone Skin
At Treats Lab, our approach to sensitive skincare is shaped by the understanding that eczema-prone skin often needs consistent support rather than only reactive solutions.
Instead of positioning products as medical treatments, our formulas are designed to support skin comfort through:
- barrier repair ingredients
- calming botanical extracts
- hydration systems that help maintain moisture
- microbiome-support ingredients
For example, ABC Microbiome Calming Lotion was developed to support the skin’s natural balance through a combination of soothing botanicals, hydration complexes, and barrier-support ingredients.
Similarly, lightweight hydration layers can help maintain comfort throughout the day. The R+R Barrier Recovery Mist delivers calming ingredients in a touch-free format designed for easily irritated skin.
A Different Kind of Progress in Eczema Skincare
The FDA plays an essential role in ensuring consumer safety. Its regulatory framework helps ensure that products claiming to treat diseases meet rigorous scientific standards.
At the same time, understanding these regulations helps explain why eczema skincare innovation often looks the way it does in the United States.
Because medical claims require strict drug approval pathways, many skincare innovations focus instead on supporting the skin’s natural systems—helping maintain hydration, barrier integrity, and microbiome balance.
This shift reflects a broader evolution in skincare: one that emphasizes daily support, thoughtful formulation, and long-term skin resilience.
