According to the brand, the Natura Bisse High Density Lift filters a revolutionary formula that is able to deliver supple, smooth, youthful looking skin. But how exactly does this product deliver on these claims? The main active ingredient in this formula is a unique complex known as the PDGF-Remodeling Complex which includes peptides and human growth factor. This product also includes hydrolyzed collagen. Each of these ingredients has been used prior in order to reduce the appearance of aging, but in comparison to ingredients like retinol, this product does not have as much evidence to back up it’s claims. With that said, we’d recommend this product for those who have difficulty with incorporating retinoids into their routine, as this could potentially produce similar results in the long term.
