What is the difference between TECA and regular Centella Asiatica extract?

TECA (Titrated Extract of Centella Asiatica) is a standardized concentrate of four triterpenoids: madecassoside, asiaticoside, madecassic acid, and asiatic acid in a fixed ratio. Unlike generic centella extract, TECA guarantees consistent concentrations of the active compounds responsible for its therapeutic effects.

How do I find TECA in product ingredient lists?

Look for any combination of Centella Asiatica Extract, Madecassoside, Asiaticoside, Asiatic Acid, or Madecassic Acid. Products listing two or more of these are close in composition to TECA. Products that specify percentages are more reliable than those that simply list the ingredient without a concentration.

Is centella safe for sensitive skin?

Yes. Its anti-inflammatory mechanism makes it particularly suitable for sensitive, reactive, and compromised skin. If you have known allergies to plants in the Apiaceae (carrot) family, do a patch test first.

Does TECA work for everyday redness, not just wounds?

Clinical studies report positive outcomes for post-laser redness, mild atopic dermatitis, and general skin reactivity. The pathway suppressing TNF-a, IL-1b, and IL-6 is the same whether the inflammatory trigger is a wound or daily environmental stress.

Centella Asiatica TECA: Six Mechanisms Behind Skin Healing

Cica entered global skincare vocabulary through K-beauty, carried by vague claims about soothing and barrier repair. Ten years on, a 2025 review published in the journal Pharmacia maps what TECA (Titrated Extract of Centella Asiatica) actually does at the molecular level, identifying six distinct mechanisms behind its skin healing activity.

What TECA Is

Centella Asiatica is a tropical plant used in Asian traditional medicine for centuries. TECA is not the whole plant. It is a standardized extract concentrating four triterpenoids: madecassoside, asiaticoside, madecassic acid, and asiatic acid. Each has a different primary function, and the combination produces synergistic effects that neither compound achieves alone.

Six Mechanisms

1. Edema Control In the early inflammatory phase of wound healing, TECA reduces vascular permeability and controls fluid accumulation in damaged tissue, stabilizing the wound environment before repair begins.

2. Antioxidant Action TECA neutralizes reactive oxygen species (ROS) and upregulates endogenous antioxidant enzyme activity. This is the first line of defense against oxidative stress from UV and environmental pollution.

3. Anti-Inflammatory Action via iNOS/COX-2/NF-kB NF-kB is the master switch of inflammatory signaling. TECA suppresses this pathway, reducing the expression of iNOS and COX-2, and lowering the release of TNF-a, IL-1b, IL-6, and IgE. This is why cica products can genuinely calm reactive skin rather than just masking redness.

4. Collagen Modulation TECA stimulates fibroblast proliferation and increases the synthesis of collagen and hydroxyproline. Hydroxyproline is the amino acid that stabilizes the triple-helix structure of collagen and is used as a quantitative marker of collagen quality. Clinical studies found significantly higher collagen content in TECA-treated wounds compared to controls.

5. Growth Factor Regulation TECA modulates TGF-b1 and related growth factors. This dual role is particularly relevant for scar management: suppressing excessive growth factor signaling reduces hypertrophic scar and keloid formation while preserving the regenerative signals needed for normal tissue repair.

6. Angiogenesis Modulation New blood vessel formation is essential for wound healing. TECA supports angiogenesis through VEGF signaling while also restraining excessive vascular proliferation. The net effect is a controlled, efficient vascular response rather than chaotic new vessel growth.

Clinical Scope

The review identifies TECA’s clinical applications as chronic wound healing, scar management, venous insufficiency treatment, keloid prevention, adjunctive therapy for atopic dermatitis, and post-procedure skin recovery. The distinguishing feature is that TECA addresses the complete healing cycle: inflammation suppression, collagen production, and vascular reconstruction, rather than targeting just one phase.

Topical application has the strongest body of evidence. Research into delivery systems including liposomal encapsulation and nanoparticle carriers aims to increase penetration depth and bioavailability of TECA actives in both topical and oral formulations.
