Review: OneSkin is THE one that is put together by women scientists who know their stuff. I used this brand for a few years and took a break when I dived into other brands. I recently went back to OneSkin to flood my skin with its highly rated ingredients. I may use other brands in between, but this brand is the one that has really shown results.
Review: Excelente producto!

A: We estimate that the 200 ml bottle of OS-01 PREP will last approximately 1-2 months, when used as directed.

**Q: What is the shelf life of OS-01 PREP? How should it be stored?**

**Q: How should I integrate OS-01 PREP into my current skincare routine?**
A: Use OS-01 PREP every evening to cleanse your skin, followed immediately by OS-01 FACE and OS-01 EYE. If you have oily skin and prefer to cleanse both morning and night, you can also use PREP to wash your face at the start of each day.
