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.
