5-STAR REVIEWS
See why customers love OS-01 FACE
“I stopped using retinol which caused me to have rough, red patches, but kept my skin supple and smooth…and now using OneSkin I still have the wrinkle reduction effects and smooth skin without the negative effects.” – Tova N.
"I love this science-backed product. It truly makes a difference to my skin and has allowed me to pare down all the other lotions, potions, & products that were more reactive in nature vs this proactive approach. Not only have I saved money on my skincare routine, but I've witnessed even skin tone, more elasticity, and a reduction in forehead wrinkles. Would recommend again and again. Can't wait to see what they think of next!" – Laura E.

- Some customers appreciate that it has no strong odor and describe it as unscented
- Others mention a mild natural smell from the ingredients that they find unappealing, though it typically fades within a minute or so
So while it contains no added fragrance, the natural ingredients may produce a subtle scent that varies by individual sensitivity.
