Replaced 3 products
Size: 1.7 Fl Oz (Pack of 1)
This is a very good product. Everyday I use CeraVe lightweight 30 or 50 spf and mix Drunk Elephant D-Bronzi and B-Goldi drops for a tint and shimmer. This is the only “makeup” I wear as I don’t like heavy makeup and prefer just a subtle glow with a daily sunscreen. This product effectively replaces all of those products for me. I put this on to try yesterday afternoon and my husband immediately said “Did you do something different? You look good.” It’s is a little more runny than I expected but applies thinly (as I prefer) and provides just enough tint to cover some of my redness. The glow is beautiful. Love the packaging, the pump is very easy to manage and keep clean. Too soon to know if it will cause breakouts or how well it holds up in the sun (although my other experiences with SunBum have been that it works well). I will update my review if I have breakouts. Buy this! Edited to add: a dermatologist complimented my skin due to this product “your skin looks great, you’re glowing!” I have not had breakouts from using this product. I still use everyday with a little cream blush and mascara and call it good. I stock up when this goes on sale but even when not on sale it is a great price. Still not 100% sure about it’s effectiveness at sun protection although I’m pretty sure it’s better than nothing. Wish this exact product was available in 50 spf. Still a fave!

A tinted sunscreen.
Size: 1.7 Fl Oz (Pack of 1)
It was really nice. However, it has a strong tint to it and feels like Makeup with sunscreen. Nice, but uninexpected.

Love!
Size: 1.7 Fl Oz (Pack of 1)
It’s a little runny but honestly doesn’t bother me at all. Gives me a good glow with a little coverage! Better than any expensive ones I’ve used & layers well with or without makeup. Just wish it was a higher spf but definitely buying again.
