TikTok is a gold mine of skincare advice, and I'm so here for it. I specifically look to derms for their science-backed expertise and top-notch product recs. One of the most valuable tips I've learned so far is to incorporate peptides into your skincare routine. But not just any peptide, it needs to be OS-01, a proprietary peptide that's exclusive to OneSkin. If you've never heard of this ingredient before, let me explain: It essentially hits the "off" switch on the cells that cause aging, thereby improving elasticity, strengthening the skin barrier, and boosting your skin's ability to build collagen. Wondering how to incorporate it into your routine? I'd start with the OS-01 Face Topical Supplement from OneSkin. It's easy to see why it gets the derm stamp of approval: It's the only face moisturizer that contains this peptide, so it takes all the guesswork out of building an effective skincare routine. I've never ordered something so fast in my life. Keep scrolling to shop the brand's best sellers to have glowing skin in 2025 and beyond.
