Great when applied correctly!!
Color: 02 - Untinted (1.7 oz)
Great sunscreen!! I was looking for a new sunscreen after I was prescribed tretinoin and sunscreen is a must! It hasn't broken me out and have noticed my skin tone is more even. I was having issues of the sunscreen pilling so my advice would be to pat into the skin first and then rub to fully blend it in. I do wear makeup everyday so applying this way makes my makeup lay so flawlessly. It has that sunscreen smell that lingers after application but it feels so hydrating that I don't always need to also use a moisturizer, applied right after toner and serums in the morning.

Great for sensitive skin protection
Color: 02 - Untinted (1.7 oz)
I have very sensitive skin especially anything that has SPF in any amount over 15. Since I have had a few issues with skin cancer on and around my face I needed something that had a greater SPF rating. This has worked great! I have not had any allergic reaction to it! It goes on smoothly, not heavy and provides good protection.

Fantastic sunscreen!
Color: 02 - Untinted (1.7 oz)
This stuff is worth the price. We use it daily. It goes on clean, not greasy. Smells great and provides excellent sun protection. We’ve used it at the beach on occasion and it protects for several hours.
I am exposed to sun for many hours at work and this provides great protection for my face.
It IS expensive, however, one pump applied to my face is enough to protect my face for many hours at work. I usually apply one to each arm as well. I’ve yet to find something that goes on as well, smells great and leaves your skin feeling moisturized while adding great protection. In my opinion it is worth the price.

Effective sunscreen protection
Color: 02 - Untinted (1.7 oz)
This product goes on smooth under makeup or by itself. It works great! I have applied the sunscreen at 8:00 in the morning and been in and out of the sun throughout the day and received no sunburn. I felt confident my skin was protected all day.

Wonderful sunscreen, but pricey
Color: 02 - Untinted (1.7 oz)
I love this sunscreen. I use it as a daily moisturizer for my face and hands. After I gently rub it on, my skin looks more supple without any greasy residue. I've been using it for years, and I'm told that I look younger than my age (68). And not just from those who are looking to complement me, but from my new dermatologist.
The only reason I'm giving it 4 stars is that its current price is out of my league. But for those who can afford it, EltaMD is a winner.
