After the age of 40, and with a growing number of years of accumulated environmental exposure, breakdown of the skin’s underlying support matrix, collagen and elastin, becomes more pronounced. Skin appears to sag because of this lost volume, especially in the lower half of the face, exacerbated by the force of gravity. To address droopiness, seek ingredients that will plump and target the support matrix, including collagen and elastin, so that the skin overall appears firmer and more lifted. Consider Glycolic Acid, Polyhydroxy and Bionic Acids, Retinol, NeoGlucosamine, certain forms of Hyaluronic Acid, CitraFill, Aminofil and Peptides.
