This oil-free moisturizer with SPF is chock-full of antioxidants, like green tea, to protect against sun damage and conditioners, like shea butter, to provide all-day hydration.

What I thought: I'm always on the hunt for SPF that won't make me look greasy and this one fits the bill. No excess shine or breakouts from this one! Because I'm typically in a rush to get to the office in the morning, moisturizers with SPF are ideal.

What Greg thought: "I like this. It made my skin feel moist. Who would've thought a moisturizer would make my face feel moist? Christina has told me a lot about sunscreen over the years but I'm still not a true believer in wearing it every day. That being said, I could see myself using this on sunny days."

This face mask is formulated with white charcoal powder to draw out dirt and debris, sodium bicarbonate to absorb oil and glycerin to moisturize.

What I thought: This was my favorite of the bunch! I love how smooth my skin felt after using this — and my face looked glowing afterward. I also liked that the mask kept its gel-like consistency the entire time I was wearing it; it didn't harden, which can be uncomfortable and also make it difficult to remove.

What Greg thought: "The mask felt sticky — it felt like I had something on my face the entire time. I didn't want to take it off because I was too busy playing a video game. My skin felt clean when I washed it off."

While I don't think I completely succeeded in turning Greg into a skin care junkie, I'm glad that he's at least open to the possibility of cleansing and moisturizing a little more regularly. Plus, along the way, I found a few new must-haves to add to my own skin care routine. That's a win-win in my book.
