The use of topical retinoids to treat skin disorders and ageing can induce local reactions, while oral retinoids are potent teratogens and produce several unwanted effects. This way, efforts to explore complementary care resources should be supported. Based on this, we evaluate the antiageing effects of a supercritical CO 2  extract from  Bidens pilosa  L. (BPE-CO 2 A) containing a standardized multicomponent mixture of phytol, linolenic, palmitic, linoleic, and oleic acids. BPE-CO 2 A was assessed for its effects on human dermal fibroblasts (TGF- β 1 and FGF levels using ELISA; collagen, elastin, and glycosaminoglycan by colorimetric assays, and mRNA expression of RXR, RAR, and EGFr by qRT-PCR) and human skin fragments (RAR, RXR, collagen, elastin, and glycosaminoglycan by immunohistochemical analysis). Levels of extracellular matrix elements, TGF- β 1 and FGF, and EGFr gene expression were significantly increased by BPE-CO 2 A. The modulation of RXR and RAR was positively demonstrated after the treatment with BPE-CO 2 A or phytol, a component of BPE-CO 2 A. The effects produced by BPE-CO 2 A were similar to or better than those produced by retinol and retinoic acid. The ability to stimulate extracellular matrix elements, increase growth factors, and modulate retinoid and rexinoid receptors provides a basis for the development of preparation containing BPE-CO 2 A as an antiageing/skin-repair agent.
