Hydrating sunscreen
This is a great sunscreen for dry sensitive skin, even combination skin specifically if you’re using acne products that can dry out your skin. My dermatologist recommended this to me due to my rosacea and dry flaky skin. It helped me maintain my skin moisturize during the day, also adds a healthy glow to the skin. It has a liquid consistency which I love cause it makes it so much easier to blend and absorbs faster into the skin. I wouldn’t recommend so much for oily skin though, it can make you look greasy really quick!!

Great sunscreen, easy to use and absorbs well
I would recommend this product because it's super easy to apply and doesn't leave a greasy feeling. The SPF 50 gives good sun protection, and it feels lightweight on my face. Plus, it's hydrating thanks to the hyaluronic acid. Definitely a good choice for daily use, and I like that it doesn't clog pores.
