Perfection! Not for very pale skin, unless it’s contour..
Color: Bronze, Color: Bronze
I only deducted a star because it was not perfect for “all skin tones”. I am very pale with cool pink undertone. Where it does give me “healthy color” without being orange (after waiting 15-20 minutes for the color to settle.), which is something I have never had before with a bronzer. I’m impressed. But… as you can see I the photo, you can clearly see where the spf ends and my shoulders begin. I prefer something more subtle so if I decide to take change my top or if my strap moves you don’t see the stark alabaster skin line. That said, if I was going to be fastidious about where my close rest on me, this would be wonderful.
Ok now the pros:
Goes on like a dream. Unscented, but the smell of the ingredients is subtle (maybe some Shea butter scent? It’s so light I can’t place it) and goes away after about 20 minutes. I have very dry, extremely sensitive skin. I mean… VERY sensitive. This feels like a high end thicker moisturizing cream/balm, but had zero stickiness or oily feeling. When I first saw the deep brown bronze color in the drops j put on my fingertips and then the orangy tint as I first put it on I started to panic. Thankfully it blended in quite well. I have NEVER had a bronzer look natural or not orange on me. So the product base is exquisite. I have bought over 27 face sunscreen products this year trying to find anything my skin would play nice with and my skin actually LOVES this. I further I have it on and I hugged my nesting partner who was wearing a light t-shirt and there was no transfer or oily blotches on his shirt as I have had with most others. I used the original version of this that has a neutral beige tint, the formulas feel identical, though I have not checked the ingredients. What is important here is it layers beautifully! I had the bronze on and because 2 hours had gone by I put the original over it and wow, I love the effect! I still can’t feel it on and it hasn’t pilled or left creases of product on my neck (unlike Elta MD Clear’s 2nd and 3rd 2hour reapplication layers.)
Here is what I am squealing with excitement about. Not only does my skin adore this product feel and formulation, but it layers! I am going to try to contour myself with the bronze. Use the Original first, and add contours under my jaw, where blush would go and my temples, blending before the product dries. Because of the way the bronze didn’t shift when I applied the original on top, it is likely that when I apply the other layers of just the original every 2 hours, it should still look beautiful.
I WILL be experimenting with how this works and how well it holds up to being outside, then update you here. (Currently I am outside less than an hour, but have enough windows o still get sun burned and sun angry red skin within 2 hours inside my home. So I still want to check for outside direct sunlight efficacy too.)
(Before this I was using SuperGoop Unseen Sunscreen, but my face still got red/irritated and EltaMD UV Clear, which had less redness/irritation, but was still causing me mild redness. Everything else was either tacky, oily or had an unacceptably white cast. The closest to 3rd runner up was the “No more foundation” it’s cosmetics moisturizing spf cream. It moisturized with zero skin irritation and had fantastic spf, but I did look like I had a plastic mask which is jot my thing. It appears I have the best of what I adored about “No more foundation” and a clear or unnoticeable tinted spf that looks plausibly natural!)

Worth the hype
Color: Glow
This is the best color correcting foundation I’ve ever used and I have tried many!
Great coverage, matches my skin tone perfectly and I don’t even feel that I need much concealer. It really does cover nicely; I avoid setting powder because it tends to make my skin look dry. This foundation has a nice dewy finish. It’s a little spendy by I will definitely add it to my subscribe and save to save a few bucks! And it has no weird scent and no discernible scent at all.

Ordinary Sunscreen
Color: Glow
There is nothing special about this sunscreen. It is as thick as any other spf 50. It is not transparent, it has a tint which stays and there is no “glow”. It feels “caky” on my face. Because of its thick nature, all the fine lines and imperfections are actually more visible.
