Refreshing, Recovery Mist
I’ve been using this COOLA Recovery+ Face Mist right after running, and it does wonders. After a run, my face usually looks flushed and feels a bit irritated from sweat and heat. A couple sprays of this helps tremendously. It provides an immediate cooling and refreshing feel without irritation. It really helps reduce that post run redness faster and it feels very gentle. It’s super easy to use. You just spray it on and let it dry.

Actually a very nice product!
Style: Fresh Rose, Style: Fresh Rose
I chose this because it scored almost 100 on Yuka which is hard to find any kind of tinted moisturizer with such a high score so I appreciate all the good ingredients. When I first tried it I wasn’t in love I thought it would have more coverage but after wearing it for a few days I am starting to really love it! It definitely keeps your face hydrated all day and gives it a definite glow! Coverage on a scale of 1-10 I would say it’s at a 2 maybe 3 but because of the hydration the good ingredients and the beautiful glow it gives my face it deserves 5 stars. A little with this product goes a long way. It’s very light don’t feel like I have anything on my face and even my husband noticed a difference, my face just looks better more even toned and glowy I will definitely continue to buy this since I normally don’t wear makeup this is a nice edition for my no makeup days to help improve my face and I don’t have to feel bad wearing it every day because the ingredients are actually good 👍

Sheer Coverage gives you a beautiful glow.
Style: Golden Hour
Beautiful tinted sunscreen, adds a really nice glow to my skin. Sheer to medium coverage. It would look best on those that take care of their skin, otherwise due to it being sheer everything will come through.
You must use your daily skincare including moisturizer for best results. I would definitely buy again however this color was a touch light for me, my skin is Carmel aka tan.

Dewy, Hydrated Skin
Style: Fresh Rose
This is all you need to know- with all the brands and influencers out there, this is the third time I've bought this. I'm not even tempted to buy the new, possibly less expensive products. I use it all four seasons alone or with my cream makeup as a primer. My skin LOVES it. It doesn't crease, separate, or do anything except make my skin look dewy and protect it from the sun. Great product!

Multiple benefit travel product
Style: Golden Hour
Love this product as it does three things:
1.Protects my skin with spf
2. Moisturizes my skin
3. Adds a slight transparent color glow
A great travel product: quick, easy and with three benefits.
