@lisa.michelle121: I had to see what would happen if I wore the Peter Thomas Roth Instant Firm Collagen Tightening Mask for a full 2 hours. Watching it change every 30 minutes was so satisfying, but the best part was the reveal. If you love collagen skincare, firming masks, anti-aging skincare, and skincare for mature skin, this is one you’ll want to watch until the end. #PeterThomasRoth #CollagenMask #FirmingMask #ptrnewarrivals #momsover30 @Peter Thomas Roth Labs
