Perfect for a skin reset
Style: Updated Formula
Sometimes I just need to reset my skin and use gentle non-irritating products. This set is perfect. The thermal water spray is the BEST. I travel with it and it always keeps my skin calm. And hydrated.

Good for sensitive skin
Style: Updated Formula
It actually helps my skin. I had curology before this and still had breakouts around my lips and nose. After trading to this, it has calmed down a lot. No bumps or pimples.
This package is smaller samples to test out to see if it's good for you and your skin. Its really good for sensitive skin.
