Beautiful finish, but not for sensitive eyes
It has a very beautiful dewy finish on the face. I wish I could keep using it however it is not good for very sensitive eyes, causes extreme itching and watering to the point where I cannot open my eyes.

Just what we needed
I am in love with this sunscreen. My daughter has very oily skin and she has tried many other susnscreens. All of them cause her skin to break out except this one. She loves putting g it on and even says it’s “kind of satisfying to put on because it disappears instantly”. It’s been working great and she hasn’t been getting sunburnt. I would definitely buy it again!!

Great sun protection for high elevation!
Excellent skin care product for those of us that spend lots of time outdoors in the mountains! My dermatologist recommended this product, and it definitely has been protecting my face while cycling, hiking, kayaking, and just hanging out in the sun!

Highly recommend.
I’ve been using Eucerin Sun Age Defense SPF 50 Face Sunscreen Lotion with Hyaluronic Acid daily for years, and it’s truly one of my holy grail products. It provides excellent sun protection while still feeling lightweight and comfortable on my skin—no heavy or greasy residue at all. I love that it contains hyaluronic acid because it keeps my skin feeling hydrated throughout the day, not dry like some sunscreens can. It absorbs quickly, layers beautifully under makeup, and never causes breakouts or irritation. After years of consistent use, I can honestly say it’s made a difference in keeping my skin looking healthy and protected. If you’re looking for a reliable, everyday facial sunscreen that also supports your skin, this is absolutely a 5-star product!

Such an amazing sunscreen!
This product gives such an amazing glow! There is no white cast, even on me a dark skin black girl. It soaks in on the skin, leaves no residue, and feels so lightweight. It’s so smoothing as well and makes your skin look so healthy. I love this sunscreen and will continue to buy if forever!
