Centella Asiatica (Cica): Why It’s Common in Korean Skincare

Centella Asiatica, often referred to as cica, is one of the most widely used ingredients in Korean skincare. It appears across many product types, from cleansers and essences to serums and moisturisers. Its popularity is not about novelty or trend. It is used because it fits well into routines designed for regular, long-term use.

In Korean skincare, centella is valued for how it supports skin comfort rather than for delivering quick or dramatic changes.

What is centella asiatica?

Centella Asiatica is a leafy plant traditionally grown in parts of Asia. In skincare, extracts from the plant are used in refined, cosmetic-grade forms. You may also see it listed under names such as madecassoside, asiaticoside, or asiatic acid, which are compounds derived from the plant.

In Korean formulations, centella is typically included at levels intended for frequent use. It is not usually treated as a strong active, but as a supportive ingredient.

Why centella is used in Korean skincare

Korean skincare places a strong emphasis on maintaining skin comfort and balance. Centella fits naturally into this approach. Scientific research suggests that compounds in Centella Asiatica, such as asiaticoside and madecassoside, interact with pathways involved in the skin’s natural repair mechanisms. In clinical and laboratory studies, these compounds have been associated with soothing irritation, supporting the skin barrier, and enhancing hydration by reducing transepidermal water loss.

It's used to help:

• Support the skin barrier
• Reduce the feeling of irritation or tightness
• Keep skin feeling settled during daily routines

Rather than pushing the skin to change quickly, centella is used to help it remain stable. This makes it suitable for routines that include exfoliation or actives, as well as for simpler routines focused on hydration.

Where centella appears in routines

Centella is found across many product types, including:

• Toners and essences
• Serums
• Lightweight moisturisers
• Cleansers designed for sensitive skin

Because it works well in lighter textures, it is often included in products intended to be layered. This allows people to adjust how much they use based on how their skin feels on a given day.

In Korean skincare routines, products containing centella are usually applied after cleansing and before heavier creams.

Who centella is suitable for

Centella is often chosen by people with:

• Sensitive or reactive skin
• Skin that feels uncomfortable after cleansing
• Skin adjusting to new products

It is also commonly used by people who prefer to keep their routines steady and low-intervention.

Centella is generally well tolerated, but as with any ingredient, individual responses can vary. Introducing new products gradually is always sensible.

How centella fits into a broader approach

Centella’s popularity in Korean skincare reflects a wider focus on consistency and moderation. Ingredients are selected not only for what they do, but for how easily they fit into daily life.

This approach is typical of Korean skincare routines, which often prioritise hydration, comfort, and gentle support over intensity.

Centella does not need to stand out to be useful. Its role is to quietly support the skin, making routines easier to maintain over time. If you want to find out more about Korean skincare, our Korean Skincare Explained article is a good place to start.
