I didn’t have high hopes for a serum sunscreen…. Until I tested this one. It is the best crossover and I love it. One pump goes a long way and your skin looks super hydrated.

What A Surprise!

I have slightly oily skin so I was really concerned about this sun screen. It is lovely! Not only does it protect my skin, it gives it a low key glow. Very pleased with it!

I have never used a sunscreen serum before. The packaging makes this easy to use. The serum itself leaves my skin hydrated and glowy while protecting me from damaging rays. This is a new to me brand but I like it!

I love this serum so much! It so soft and makes my skin glowing through out the day! I love how it feels on my face but unfortunately i'm not a big fan of the smell. But i like the after effects on my face
