Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Gotu kola (Centella asiatica) is used in various topical formulations aimed at reducing the appearance of stretch marks (striae). The scientific basis for its use comes from both laboratory and limited clinical studies. Gotu kola contains compounds such as asiaticoside, madecassoside, and asiatic acid, which have been shown to stimulate collagen synthesis and improve wound healing. Collagen is a key structural protein in the skin, and its increased production may help improve skin elasticity and resilience, potentially reducing the formation or visibility of stretch marks.

A few small clinical studies have evaluated gotu kola-containing creams (often in combination with other ingredients) for preventing or minimizing stretch marks, especially during pregnancy. Some results suggest a reduction in the incidence or severity of stretch marks compared to placebo, though these studies often lack rigorous controls and isolate gotu kola's effects poorly. Additionally, the European Medicines Agency recognizes Centella asiatica as a traditional herbal remedy to support wound healing, which may be relevant since stretch marks represent a form of dermal injury.

In summary, while there is a plausible scientific rationale and some early evidence for gotu kola's beneficial effects on skin repair and elasticity, robust clinical data specifically supporting its efficacy for stretch marks are limited. Therefore, the overall evidence supporting its use for this purpose is modest (rated 2/5), and more high-quality research is needed to confirm these effects.
