Sampled Mary Kay's TimeWise Day & Night Solution.
The day solution is a sunscreen. I don't like the smell and the texture. It feels so icky.
Initially, I was intrigued by the night solution. My skin feels moisturized in the morning after. On the second day, it doesn't give the same effect anymore. A classic one hit wonder.
To be fair, I only used it for a week and I didn't use the whole range. My opinions might be premature/ inaccurate.
