My favorite sunscreen for being active outside
Size: 6 Fl Oz (Pack of 2), Style: Lotion
I bought this last summer and now it's my go-to. I love it. It absorbs quickly, is very easy to just smear on, and has a nice, very light scent. I wear it when I go running and I sweat like a maniac so that tells you something.

Possibly the best sunscreen on the US market
Size: 6 Fl Oz (Pack of 2), Style: Lotion
I'm a self-confessed sunscreen snob. I love trying new formulas, and I came to the conclusion years ago that US formulas aren't usually for me. We haven't had a new filter approved by the FDA since the last millennium, and our products reflect that. I can't tell you how many times I spent $40+ on 1.7oz of sunscreen that I ended up hating before I switched to mostly Korean sunscreens; and most of the US sunscreens I like can be described as "good...for a US formula."
In short, I didn't have high hopes for this, and I was very pleasantly surprised. This is a very, very good sunscreen even among non-US formulas. It's lightweight, doesn't make my oily skin shiny, and dries down entirely so it doesn't feel tacky or slimy. I can layer over and over throughout the day without pilling or streaks. It also comes in a huge tube for a very low price. The only possible downside is that it's fragranced, which isn't a deal breaker for me. I wish they still sold the 3oz facial version because it's travel-friendly, but from what I can tell, it's the same formula.
Try this, especially if you hate thick, heavy, shiny sunscreens. Unless you can't do fragrance, I think you will be very happy with it.

Favorite Sunscreen!
Size: 6 Fl Oz (Pack of 2), Style: Lotion
We absolutely love this SPF. It’s been our go-to for years. It does not make your skin feel sticky or crunchy. It goes on so smooth (like air!) and absorbs so well. It feels like the softest moisturizer. And it works! We get the two pack every summer. It’s also kinda hard to find. Amazon always comes through! Highly recommend.

Fave sunscreen!!
Size: 6 Fl Oz (Pack of 2), Style: Lotion
This is my absolute favorite sunscreen. It got my husband to finally start wearing sunscreen at work- it’s the only one he’ll wear.
The texture feels so smooth and lightweight on my skin and it covers very well. It also smells delicious.

Inexpensive, effective, non-greasy and invisible
Size: 6 Fl Oz (Pack of 2), Style: Lotion
This is the most economical option for those looking for a very effective but invisible and light sunscreen. I found it very easy to apply and rub into the skin and within a few seconds it had been absorbed into my skin creating a dry and invisible UV ray barrier that I was barely aware of. The two pack was 12 ounces for $15.95—or about $1.30 per ounce—a fraction of the cost of some of the boutique and facial moisturizing sunscreens that will set you back as much as $20.00 per ounce. I use this product often as I rock climb outside here in Las Vegas once a week all through the summer months. The sun is very intense in the Mojave desert, and I have extremely pale white skin that doesn’t tan and burns easily with minimal exposure. This is a chemical—not a mineral based formulation, and it fulfills the required task of preventing my skin from burning.
