Do you suffer from recurring acne on your face, unbearable itching, and poor skin condition? In South Korea, there is an ingredient called Centella asiatica, which is highly popular in the skincare industry for its calming and anti-inflammatory properties, as well as its ability to protect the skin. So, is centella asiatica extract (asiaticoside) truly beneficial for the skin? Today, we will take a deeper look at its benefits.

What is Asiaticoside?

Asiaticoside is a triterpenoid saponin compound derived from Centella asiatica. The core component of centella asiatica extract is an active saponin with emulsifying properties—making it a key ingredient for skin hydration. Additionally, asiaticoside exhibits strong anti-inflammatory, antioxidant, and wound-healing effects, which is why it is widely used in the cosmetics industry.

The benefits of Asiaticoside in skin care

Asiaticoside has been shown to help delay skin aging.

Asiaticoside exhibits strong antioxidant properties, effectively neutralizing free radicals in the skin, boosting superoxide dismutase(SOD) activity, and helping to reduce wrinkles. Additionally, its antioxidant effect is comparable to vitamin C, but gentler—making it more suitable for sensitive skin types.

Asiaticoside helps calm, soothe, and reduce inflammation.

Asiaticoside exhibits significant anti-inflammatory properties. Inflammation plays a crucial role in wound healing processes, and many skin conditions—including acne, eczema, and other dermatological disorders—are fundamentally inflammatory in nature. By inhibiting pro-inflammatory cytokines such as TNF-α and IL-6, asiaticoside helps reduce skin redness, swelling, and may even prevent acne scarring.

Asiaticoside can repair the skin barrier.

Asiaticoside (the active glycoside in Centella asiatica) is among the most potent ingredients for restoring the skin's barrier function. It repairs compromised skin barriers and enhances their resilience through dual mechanisms: collagen stimulation and intense hydration. Furthermore, asiaticoside promotes the synthesis of key structural proteins—including collagen type I and fibronectin—thereby accelerating wound healing. Increased collagen production and optimal hydration collectively contribute to improved skin density, tensile strength, and elasticity, ultimately reinforcing a fully functional cutaneous barrier.

Asiaticoside has moisturizing and water-locking effects on the skin.

Asiaticoside enhances stratum corneum hydration capacity, functioning similarly to natural moisturizing factors (NMFs). Additionally, it reinforces the skin barrier's moisture retention capacity while reducing erythema and inflammation, resulting in improved skin hydration and texture.

The side effects of Asiaticoside

Asiaticoside is a popular ingredient in skincare products because it is generally safe, mild, and has minimal side effects. However, there are exceptions—some individuals may be allergic to Asiaticoside, with the most common reactions being a burning sensation or contact dermatitis. Therefore, before using skincare products containing Asiaticoside, it is important to perform a patch test on the inner arm and wait at least 24 hours to check for any adverse skin reactions.

Conclusion

Asiaticoside has antioxidant, anti-inflammatory, and moisturizing properties, which can help delay skin aging, repair the skin barrier, and maintain smooth, hydrated skin. As a result, they are widely used in the skincare industry.
