What Is Centella Asiatica (Cica) and Why Is It in Your Bug Bite Patch?
Share
Centella asiatica is a small leafy plant that has been used in Asian traditional medicine for skin conditions and wound healing for thousands of years. In Korean skincare it is known as cica — short for the scientific name — and it appears in everything from moisturizers to serums to wound patches. It is in SUPERBAND Bugs specifically because of what it does to the type of skin disruption a scratched insect bite creates.
Here is the science behind it, without the marketing language.
What centella asiatica contains
The active compounds in centella asiatica are triterpenoids, primarily:
- Asiaticoside — promotes collagen synthesis and wound healing, stimulates fibroblast activity
- Madecassoside — anti-inflammatory properties, antioxidant activity, supports skin barrier restoration
- Asiatic acid — enhances collagen production, modulates inflammation, supports tissue regeneration
- Madecassic acid — wound healing support, anti-inflammatory activity
These compounds work through several overlapping mechanisms that are relevant to skin wound healing and inflammation management.
What the research shows
Collagen synthesis and wound healing
Multiple studies have confirmed that centella asiatica compounds stimulate fibroblast proliferation — the activity of the cells responsible for producing collagen and extracellular matrix, which are the building blocks of healing skin. A 2024 review published in Pharmaceutics (Witkowska et al.) summarized the evidence: topical centella asiatica applications have been shown to accelerate wound healing, reduce wound size, and improve recovery times across wound types including burns and chronic wounds.
Asiatic acid specifically has been identified as directly associated with wound healing activity — research published in PubMed found it promotes fibroblast proliferation and collagen synthesis, which are the mechanisms that close wounds and rebuild skin structure.
Anti-inflammatory modulation
Madecassoside, one of cica's primary active compounds, has documented anti-inflammatory properties. This matters for bug bite wounds specifically because the wound exists within an already-inflamed environment — the immune response to mosquito saliva creates local inflammation that persists even after scratching stops. Centella asiatica does not eliminate that inflammatory response, but it modulates it — reducing the sustained low-grade inflammation that can slow healing and increase the likelihood of post-inflammatory pigmentation.
Skin barrier restoration
Centella asiatica extracts have been shown to support keratinocyte migration and skin barrier repair. For a scratched bug bite, where the stratum corneum — the outer protective layer of skin — has been disrupted, this barrier restoration activity is directly relevant. The cica works to rebuild the structural integrity of the skin surface while the hydrocolloid coverage above it maintains the moist environment that healing requires.
Why it pairs with hydrocolloid for bug bites specifically
A scratched bug bite involves two overlapping problems: an open wound that needs wound care, and an inflamed, disrupted skin environment driven by the underlying immune response. Hydrocolloid addresses the wound. Centella asiatica addresses the inflammation and barrier disruption.
Neither alone is the complete solution. Hydrocolloid coverage over an inflamed bite without cica manages the wound well but does nothing to modulate the inflammatory environment that persists underneath. Cica applied to a scratched bite without coverage leaves the wound open to further scratching and contamination. The pairing in SUPERBAND Bugs combines the mechanisms that the specific wound type requires.
Centella asiatica in Korean skincare vs. wound care
Cica became a skincare staple in Korea for barrier-compromised and sensitive skin — it calms redness, supports barrier repair, and reduces the appearance of irritation. The skincare application and the wound care application share the same underlying mechanisms. The active compounds that reduce redness in an irritated skin condition are the same ones that modulate inflammation in a healing wound.
SUPERBAND Bugs takes the ingredient from a skincare context and applies it where the biology is most directly relevant: on a wound that has both an open skin injury and an ongoing inflammatory response to manage.

Frequently asked questions
What is centella asiatica?
A plant used in Asian traditional medicine for skin conditions and wound healing, also known as gotu kola or cica. Its active compounds — asiaticoside, madecassoside, asiatic acid, and madecassic acid — promote collagen synthesis, modulate inflammation, and support skin barrier restoration.
What does cica do to skin?
It supports wound healing through collagen synthesis promotion, modulates inflammatory response, supports skin barrier repair, and provides antioxidant protection. Well-documented in peer-reviewed research across wound types.
Why is centella asiatica in bug bite patches?
Scratched bug bites create a wound within an inflamed environment. Cica addresses the inflammatory and barrier-disruption component while hydrocolloid addresses the wound itself. The combination is more complete than either alone for the specific wound type that scratched bug bites represent.
Is centella asiatica safe for children and sensitive skin?
Yes. Centella asiatica is well-tolerated across skin types including sensitive and eczema-prone skin, and is used in pediatric skincare formulations. SUPERBAND Bugs is latex-free and formulated for sensitive skin.
Is this the same as the cica in Korean skincare?
Same ingredient, same active compounds, directly applicable mechanisms. The wound healing and anti-inflammatory properties that make it effective in skincare are exactly the properties that make it appropriate for wound care on scratched bug bites.
