Centella Asiatica: A Time-Honored Ingredient for Stressed Skin

In Korean skincare traditions, caring for sensitive skin has long focused on restoring balance rather than forcing change.

When the skin barrier becomes stressed—whether from dryness, irritation, or environmental triggers—the goal is often to calm the skin and support its natural resilience.

One botanical ingredient that has been trusted for generations in Korea is Centella Asiatica, often known today as Cica.

Derived from the leaves of the Centella asiatica plant, this ingredient has been used across Asia for centuries in traditional herbal medicine to help comfort stressed skin. In modern skincare, Centella is valued for helping soothe visible irritation, support the skin’s moisture barrier, and maintain hydration.

At Treats Lab, our philosophy sits between traditional Korean skin wisdom and modern dermatological research. We use Centella in its full-spectrum form, alongside two of its key compounds—Madecassoside and Asiaticoside—to help support calm, resilient skin over time.

 

What Is Centella Asiatica Leaf Extract?

Centella Asiatica Leaf Extract is a botanical ingredient derived from the leaves of the Centella asiatica plant, a medicinal herb native to many parts of Asia, including Korea.

In Korean herbal traditions, Centella has long been valued for its calming and restorative qualities. Historically, the plant was used to help comfort stressed or injured skin—an origin that still shapes how it is used in modern skincare.

The plant contains naturally occurring compounds known as triterpenoids, including:

• madecassoside
• asiaticoside
• asiatic acid
• madecassic acid

These compounds are believed to contribute to Centella’s ability to support skin repair and barrier resilience.

Modern research has helped explain these traditional uses. It's been shown that Centella’s triterpenoid compounds may help support skin repair processes and barrier function.

Because of this combination of traditional use and modern research, Centella has become a cornerstone ingredient in many barrier-support and calming skincare formulas.

 

What Does Centella Asiatica Do for Skin?

Centella Asiatica is widely valued for its ability to help calm and support stressed skin.

Rather than acting as an aggressive active ingredient, Centella works by helping reinforce the skin systems responsible for maintaining balance.

Its most recognized skincare benefits include:

• helping soothe visible irritation
• helping support the skin moisture barrier
• helping maintain hydration
• helping improve the appearance of skin resilience

These effects are closely connected to the plant’s triterpenoid compounds.

Research published in the Journal of Clinical and Aesthetic Dermatology notes that Centella compounds—particularly asiaticoside—may support collagen synthesis and skin repair pathways.

In simple terms, Centella helps support the processes that allow skin to remain strong, hydrated, and resilient.

That’s one reason it appears so frequently in skincare designed for sensitive or reactive skin.

 

Why Sensitive or Reactive Skin Often Benefits From Centella

Sensitive skin is often a reflection of a weakened skin barrier.

When the barrier becomes compromised, moisture escapes more easily and irritants can penetrate the skin more quickly. This can lead to dryness, visible redness, or a general feeling of discomfort.

Ingredients like Centella help support the skin during this stage by encouraging:

• improved moisture retention
• calmer-looking skin
• stronger barrier resilience

Rather than pushing the skin toward rapid change, Centella supports the gradual restoration of balance—an approach that aligns closely with Korean skincare philosophies centered on long-term skin health.

 

How Centella Asiatica Supports the Skin Barrier

A healthy skin barrier helps maintain hydration and protects the skin from environmental stress.

Centella supports this barrier through several pathways.

Supporting Skin Repair Processes

Centella’s key plant compounds—especially asiaticoside and madecassoside—have been studied for how they support the skin’s natural repair processes. These compounds appear to help stimulate fibroblasts, the skin cells responsible for producing collagen and maintaining skin structure.

Research published in the journal Pharmaceutics suggests that these Centella compounds may help support collagen synthesis while also helping the skin recover from stress.

In practical terms, that means Centella can help support skin that looks stronger, calmer, and more resilient—especially when the skin barrier has been compromised.

Helping Calm Visible Irritation

Centella also contains compounds associated with soothing effects in the skin, helping reduce the appearance of redness and discomfort.

Supporting Hydration Balance

When the barrier becomes weakened, moisture can escape more easily. By supporting barrier integrity, Centella helps the skin retain hydration more effectively.

 

Ingredients That Pair Well With Centella Asiatica

Centella works best when combined with ingredients that support hydration and barrier resilience.

Ceramides

Ceramides are lipids naturally found in the skin barrier. When used alongside Centella Asiatica, they help reinforce the skin’s protective layer while Centella helps calm the appearance of redness and irritation. Together, these star ingredients like Ceramide NP, help support skin that feels more comfortable, hydrated, and resilient.

Beta-Glucan

Beta-glucan is a soothing humectant known for helping attract and retain moisture. When paired with Cica, it helps improve hydration levels while supporting skin that feels dry or easily irritated.

Peptides (Copper Tripeptide-1)

Peptides such as Copper Tripeptide-1 help support the skin’s natural renewal processes and overall resilience. When combined with Centella Asiatica, this pairing helps support skin that appears calmer, smoother, and more balanced over time.

Amino Acids

Amino acids are important components of the skin’s natural moisturizing factors. Used together with Centella, they help maintain hydration and support skin balance, particularly for skin that feels easily stressed.

Barrier Lipids (Squalane and Triglycerides)

Barrier-supporting lipids like squalane and triglycerides help seal in moisture and reinforce the skin’s protective layer. After Centella helps soothe the skin, these lipids help maintain hydration so skin stays soft, comfortable, and supported throughout the day.

 

How Treats Lab Uses Centella

At Treats Lab, skincare exists between science and care.

Our formulations draw inspiration from Korean skin-health traditions, where calming and supporting the skin barrier is often the first step toward healthier skin.

Our Cica approach uses full-spectrum Centella combined with two of its key compounds—Madecassoside and Asiaticoside.

This combination brings together the broad botanical benefits of the plant with the targeted properties of its most studied compounds.

Together, they help:

• comfort sensitive skin
• support the appearance of a healthy skin moisture barrier
• contribute to skin that looks stronger and more resilient

You’ll find this approach in formulas like the ABC Microbiome Calming Lotion, where Centella works alongside microbiome-support ingredients designed to help maintain balance.

For hydration throughout the day, the R+R Barrier Recovery Mist helps replenish moisture while supporting skin comfort.

And for a simplified routine designed for sensitive or eczema-prone skin, the Calm & Restore Duo brings together barrier-support products that help maintain calm, balanced skin.

Because caring for sensitive skin should feel supportive, restorative, and intentional.
