Bitcoin is starting to come into its own as a digital currency, but the blockchain technology behind it could prove to be much more significant.

Sun-kissed skin
This was the best kit to take to the islands. Loved the fragrance and didn’t burn. (Just follow the directions!)

Great for sensitive skin
Scent: Fragrance Free, Size: 1.7 Fl Oz (Pack of 1)
I usually have problems with fragrance in almost any face cream or sunscreen, and my skin reacts very easily, so I’m always careful with what I use. I tried the COOLA Organic Face Sunscreen SPF 50 Sunblock Lotion (Fragrance Free) and I’m honestly impressed. It feels very light on the skin, doesn’t irritate my face at all, and finally a sunscreen that doesn’t have that strong smell that usually bothers me. It absorbs well, works great under makeup, and gives good daily protection without feeling greasy. If you have sensitive skin or issues with fragrance like I do, this one is definitely worth trying.

Love this sunscreen
Scent: Fragrance Free, Size: 1.7 Fl Oz (Pack of 1)
I would love to buy again, but I go through sunscreen, I have to find a little less expensive one. No burn, dewy not greasy look. Great for mature skin. No fragrance, works well, melts right in the skin. I do love this product and the spray too!

Light and works with no eye stinging.
Scent: White Tea, Size: 1.7 Fl Oz (Pack of 1)
I love this sunscreen. I wear co tact’s and most sunscreen ends ups burning my eyes. This does not! It has a nice cucumber smell and it’s not sticky or heavy. By far the best face sunscreen that’s light, smells nice, doesn’t burn my eyes and works.
