What it is
Mixture of Ile-Pro-Pro (IPP) and Val-Pro-Pro (VPP) tripeptides derived from casein fermentation by Lactobacillus helveticus; originally characterised as ACE (angiotensin-converting enzyme) inhibitors via oral administration; topical application studied for skin barrier support and modulation of metalloproteinase activity in UV-stressed skin; proline-containing sequences are recognised by fibroblast collagen receptors, providing a biological rationale for matrix support activity; used in anti-ageing and firming concentrates.
Where it sits
Serums sit after toner and before moisturiser. Thinnest to thickest, water before oil.
