This is the manufacturer's public product page used as a source for product-catalog facts only: product naming, branding, format, named ingredients, retail availability, and pricing.

On a Product page in the SKB, peer-reviewed efficacy studies are inappropriate Sources because listing them implies \"these studies validate this specific product\" — which is review / efficacy framing. Product-fact-verification sources (this page, and any future manufacturer clinical data sheets) are the appropriate Sources for a Product entity. Peer-reviewed efficacy literature for the Matrixyl ingredient is cited on the Matrixyl Ingredient page, where it belongs."]}],"source_type":"official_product_page","original_source_url":"https://dermagist.com/matrixyl-serum/"}
