Does Thin Foundation, but doesn't look Good

I gave this 2 stars, because it does dilute a heavier Foundation and adds a glow, but it doesn't mix well with any Foundations I tried - it immediately ends up looking patchy...sadly I wasted my money on this pricey product.

Worth trying!!!

I bought this and the rhode illuminating glaze. Returned the rhode which did nothing and kept this. More impact, live the dilution option for less coverage in the summer but with luminous blurring. Def worth trying

Glowy not glittery

Love this product. A staple in my summer makeup routine. Adds radiance without looking very glittery because the sparkles are so fine. I either apply after primer before foundation or mix with my foundation.

Pills so bad

Did this formula change?? I absolutely LOVED this— and now on my second bottle it pills under every single thing I’ve used it with. By itself, foundation, moisturizer- I cannot combine it with anything.

I love it. Will buy the other color in the future.

I don’t leave reviews often but I love this product. I love that even though it’s a light iridescent shade it doesn’t change the color of my foundation. It leaves an all day glow without glitter. It’s absolutely beautiful. And then with the powder melt spray!!!! My makeup looks amazing. It’s what the saie glow gel thought she was…no shade. I have acne prone skin and was hesitant since this is a skincare forward product but it doesn’t dry me out, it keeps my base hydrated and doesn’t break me out most importantly. It is good!

Get a subtle glow on!

I purchased this product during the last VIB sale because I was looking for a primer. After using it for about a month, I love it! I use this product under my foundation and it gives a very subtle glow. It doesn't make my t-zone or chin look greasy eventhough I tend to get oily in those areas. I have been getting compliments on my skin and this is the only thing that has changed in my routine.

Wished the best based on the ingredients

I bought the radiant finish (bronzing one) and the pearlescent finish. My. Skin. Broke. Out. So. Bad. Like, the worst I’ve EVER seen it. Like, red welps on my cheeks. They didn’t go away for almost a week. wanted to

Fabulous multi use product

I own this in both colors - I first bought bronze, then knew I had to get the pink as well. This is a FANTASTIC product with multiple uses which I appreciate. My favorite way to use though is to mix with my foundation - I have tried the bronze shade mixed with a foundation that's just a tad light for me and it worked out wonderfully. I've also used the pink shade mixed with the sarah creal face flex, which is a tad dark on me. I just dabbed the face flex all over my face, then added this product to my fingers and used my hands to blend everything together, perfect finish!!! The Sarah Creal product is kinda thick so this helped thin it out to spread it out, and it adds a subtle glow, it's not too shimmery at ALL in either shade. One thing I have yet to do is wear it on its own for the days I dont want to wear makeup, I will try soon. I highly recommend both colors they really are wonderful. Oh almost forgot to mention, the formula is quite thin/watery and it is NOT super pigmented but that is exactly what I want, because other bronzing or glow products are a bit TOO pigmented and are hard to work with, these are very forgiving and more natural.

Perfect for a bronzey glow

I’ve been using the One/Size Base Thinner Bronzer and I love it! The formula is super lightweight and blends effortlessly into the skin without looking patchy or muddy. It gives the most natural, sun-kissed warmth while still adding definition to the face. It also sits beautifully over foundation and doesn’t disturb the makeup underneath. The finish looks smooth and skin-like, and it lasts all day without fading. Definitely one of those bronzers that makes your complexion look healthy and naturally glowy.
