Ingredient evidence

TECA and stretch marks: what the evidence shows

TECA is a titrated extract of Centella asiatica. Research on specific Centella-containing formulas is relevant context, but it cannot be transferred automatically to every cream or finished product.

Evidence reviewed 19 July 2026

Why formulation matters

An ingredient name alone does not establish performance. The extract specification, concentration, complete formula, study population, application schedule and outcome being measured all affect what a study can support.

How Stria Lab presents TECA

Stria Lab uses TECA within its Stretch Mark Cream. Stria Lab does not state a TECA concentration or quantitative finished-product result on this page because those claims require substantiation for the exact current formula.
