Favorite Daily Moisturizing Sunscreen!
I heard about this product on Dr. Dray's You Tube Channel. She is a great dermatologist that gives excellent recommendations on sunscreens and beauty products. She uses science based research & reputable companies. She is also conscious of product costs and offers budget friendly options to protect your skin. Eucerin is one of her favorites and sunscreen is a daily requirement, not a recommendation if you want to keep healthy skin. I have been on the search for years for a favorite. I kept getting greasy results or a white cast. This one offers more of a moisturizing effect as it has hyaluronic acid in it along side sunscreen to protect your skin. I have never had a white cast from this one. It is not waterproof, but a nice one for daily use and under make up. It doesn't smell or clog my pores. I have used about 4 bottles at this point and plan to keep using this one. It is great! I also use the body sunscreen in the tube as well. I like them both.

Absorbs well; no oily feel. Great sun protection!
I got a sample of this from my dermatologist and loved it so I switched to this brand! It has a lightweight feel, absorbs well without leaving a white cast, and has a matte-like finish without feeling dry. It's similar to Laroche-Posay Anthelios Clean Sunscreen, but is more moisturizing and a lot cheaper! I have rosacea - this sunscreen doesn't cause breakouts. I use the 50 SPF facial moisturizer on my face (duh) and the tube of the 30 SPF on my neck and chest. Great products!

Amores y semiodios
Tengo la piel del cuerpo seca y la de la cara es mixta con tendencia al acné. Decidí probar estos protectores solares, ya que uso productos que dejan mi piel fotosensible. Probé el protector solar corporal y me gustó. Tiene una consistencia bastante líquida, pero se esparce muy fácil. Se demora un poco para absorber, no deja una sensación pegajosa ni grasosa, pero se siente un poco pesado por un ratito. Inicialmente deja un olor algo fuerte e incómodo, que en un par de minutos desaparece. No me expongo directamente a la luz del sol casi nunca, pero no he notado ningún tipo de quemadura y oscurecimiento de la piel, por lo que creo que cumple con la protección solar. En general, me gustó el producto. Otra historia es el protector solar facial. Tiene una consistencia tipo crema, se esparce fácil, no deja residuo blanco, no deja sensación grasosa o pesada. Se absorbe rápido. Pero luego de un par de usos, me brotó la piel del rostro. En cambio, a mi esposo que tiene piel seca en su carita, le ha servido mucho. No le ha generado ningún tipo de reacción adversa y su piel lo aceptó desde el primer momento. Luego de una semana de uso, no tiene ninguna queja al respecto. En fin. Los productos son bastante buenos, pero yo, con mi tipo de piel, no usaría el protector solar facial.

So far we're loving it
Started using this about a month ago. The price for both was cheaper than just the face one at my local store so I decided to try them. I use it for me kids as well as myself and so far it's worked great. It doesn't have an overwhelming smell and doesn't leave a greasy film like some others. My kids used it and then we're outside swimming for about 2.5 hours. They got some color on their faces but we didn't reapply so I wasn't surprised. I was outside during that time too and didn't burn at all (I wasn't swimming) where I had applied it. So far I love it and will continue using.
