Great option for a natural finished look
Size: 1.8 Fl Oz (Pack of 1), Color: Original, Size: 1.8 Fl Oz (Pack of 1), Color: Original
I have been using Colorscience Total Protection Face Shield SPF 50 Original color for over 5 years. I love that the color blends with your skin so well and provides a natural looking finish.
It does not cover all of my dark spots or defects, but it makes my natural skin look better. The finish is soft and silky and the 50 helps protect my skin from additional sun damage. If you are looking for a more natural finish, this is a great choice.

Made my blush look orangey
Size: 1.8 Fl Oz (Pack of 1), Color: Original
I absolutely loved the feel and finish of this tinted sunscreen, but with or without my foundation on top of it, my Benefit Dandelion blush went from pink to a shade of orange. I have fair skin, blue eyes and strawberry blonde hair, which at this time of year is more strawberry than blonde. The orangey shade is definitely not my color. I was sad that this didn't work out, because the Colorscience made my skin look radiant really, until an hour or so after blush was applied. I so wanted a replacement for the Australian Gold Mineral sunscreen in original tint, because even though that tint looks great color-wise, it also makes my skin look dry and therefore accentuates my wrinkles, even when I mix it with Olay microsculpting cream moisturizer before I apply it. The Colorscience didn't accentuate the wrinkles. I feel certain this color issue is either a conflict with my Olay moisturizer, my own chemistry or the Benefit blush; maybe a combination of the three. If you have oily skin this sunscreen is moisturizing so it might not work for you. Otherwise, you may want to give this a try. Hate that I had to return it. No matter what, I've had a run-in with skin cancer, so I won't go without spf. I just have to keep looking ancient and dry with AG until I find one that works better for my coloring, skin type, and that plays well with my moisturizer and blush. I'm 62 yrs young, normal to dry combo skin. Hope this helps!

Brown skin friendly! No white cast! 🥳 Bye dark spots!

Brown skin friendly! No white cast! 🥳
Colorescience comes through again! This is a fantastic sunscreen. It’s SPF 50 and it protects against blue light. So if you’re trying to get rid of hyperpigmentation, this will help you on your journey. I usually use tinted sunscreen for that reason but luckily, we have a non-tinted option with this! I use this primarily on my body because it doesn’t get stain clothing. But sometimes I use it on my face too, on its own or under a tinted formula. I like the light coverage for my face to even out my skin tone.
The texture is light and thin; reminds me of Tatcha silk screen but without the slight tint. This goes on white but somehow disappears into my skin. Also the price point is a better value, here. Even better when it’s on sale! I love Tatcha and use it regularly but I am happy to have this in my stash now. I had to get the big bottle when it was on sale. The formula is very elegant and leaves a natural finish. It spread and blends like a dream! It is so quick! You will NOT have to rub this in for 30 minutes to get it to blend. This physical sunscreen is a daily essential for me. It doesn’t burn my eyes or irritate my oily skin. It’s water resistant for 40 min, so it’s good for the summer heat.
But where are all the photos? Cause sometimes we need proof, right? Well, here is my contribution. I’m wearing this on my body (neck, chest, arms, legs, hands and feet).
* I reached out to Colorescience to ask about the effectiveness against UVA (aging) rays for this product. Other countries will usually mark this on a PA scale, the strongest protection being PA++++. But in the US, sunscreen isn’t required to specify how much; they are required to make sure it has at least the FDA “minimum” protection against UVA, and UVB (burning) rays and they have to label it “Broad Spectrum.” SPF is the protection level against UVB only. Colorescience has started to label some of their products with PA++++. Since this wasn’t labeled like that, I asked. They told me they recently completed testing and No-Show has earned the PA++++ rating. So they are in the process of updating the packaging. Colorescience knows what we want, even though the FDA is asleep at the wheel.
