For full-body protection, try Kiehl's Activated Sun Protector.

Birchbox Breakdown

By now you should know SPF isn’t just for the beach—it’s an everyday affair. What you might not know is that an effective sunblock doesn’t have to be thick, goopy, or chalky. Kiehl’s latest innovation, Super Fluid Defense SPF 50+, offers a serious level of protection in a translucent, oil-free, and water-resistant formula that’s so light, you won’t even notice it.

How it Works

Five different sun filters are utilized in this powerful, broad-spectrum formula. The first three, Homosalate, Octocrylene and Octisalate, protect against sunburn-causing UVB rays. Just as important are Parsol 1789 and Oxybenzone, both of which shield against the UVA rays that cause skin damage and premature aging.

How to Use

Shake it, baby! No, seriously, you have to really shake this product before using it. In order to achieve such a lightweight texture, the chemists at Kiehl’s developed an innovative non-homogenous formula. Shake it to combine all the ingredients and to ensure your skin maximal protection. Apply daily to face and décolleté — it can be worn on its own or under makeup.

Yay for Sunscreen!

A great sunscreen that's so light that you barely feel it on the skin. So light that even my super oily boyfriend can use it everyday. Plus thank goodness for the high SPF. For that reason it's my go-to for everyday sunscreen.

If your eyes are sensitive, skip this one.
Purchased

Once this is on, it's light and good under makeup, but this moisturizer stings my eyes when it goes on. Which is a bummer, especially for the high price.

Go To Sun Protection For My Face
Purchased

This is a great product that I keep in my purse. I have VERY fair skin and am prone to sunburn at a moment's notice. So many sun lotions clog my pores and make my skin break out, but this one hasn't. Lightweight, sinks in easily and quickly, doesn't feel mask-y. Highly recommended.

Love it!
Purchased

Light enough to wear every day under makeup. Smooth, light formula that feels smooth and matte on skin. I have oily skin and I was worried that this was going to make me more oily but that was not the case at all. Love this product, just hope it has as much sun protection as it claims to have.

Great matte sunscreen under makeup

This is a great matte sunscreen under my makeup. I find it lasts all day and helps keep my sun spot and melasma issue at bay. It is a milky liquid format that you shake before dispensing. I use it under my makeup and it plays so well with my makeup keep it even and matte underneath!

Best facial sunscreen

I have been using this for years - replacing every spring. I never get a sunburn or freckles - so I think it must be working. It is lightweight and has no scent - I put it on every morning before running and I never feel it.
Have used it in a pinch on arms, chest...too

Great sunscreen

I use this every day over my moisturizer. Lightweight and not too heavy, even for my oily skin. It smells nice too
