Almost a home run
Size: 1.8 Fl Oz (Pack of 1), Color: Original
Initially I really loved how this sunscreen made my skin look. The tint provided enough coverage to even my skin tone and hide my remaining melasma. It gives a very nice glow that doesn’t look too greasy. I have dry skin, and this was moisturizing enough for summer; although I would probably need a moisturizer first in winter.
After using this product for many weeks however, I realized that it leaves residue on my hair making it feel chalky and dry. I’ve tried different techniques of washing my hands really well after so I don’t spread residue to my hair when I fix it, but I found it still made it’s way into my bangs. I even tried pulling my hair back and wait an hour before putting it down but inevitably my hair got this dirty chalky feel to it. It makes me feel dirty which is enough to deter me from wanting to use it exclusively.
I wanted to use a tinted physical sunscreen to stop the pigmentation to my melasma, but I just prefer how chemical sunscreens feel. I started to use this over my cheekbones after I apply my chemical sunscreen to help deflect blue light, but I think going forward I’ll just purchase a more affordable option if it is going to be used on such a small area.

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!
