In both preclinical and clinical tests, it was shown that administration of Centella asiatica was capable of proliferating fibroblasts, activating the Smads pathway, increasing collagen synthesis, reducing metalloproteinase activity by increasing collagen deposition, and reducing melanin content in melanocytes so that it can modulate melanogenesis by inhibiting the expression of tyrosinase mRNA.]]>
