Not sticky, lightweight light shimmer/glitter sunscreen setting spray.
Color: 1 Pack, Color: 1 Pack
If you like just a touch of sparkle along with some sunscreen and setting spray this is fantastic. This doesn't leave you looking like you are going to a rave, rather it is more like you have been crafting and there is a bit of glitter. It is sheer other than the touch of sparkle. It is not sticky it dries and feels almost like it isn't there at all. There is seventy five ml in this bottle just over two and a half ounces. The sprayer mists quite well so there is even coverage. This works equally as well to set your make-up and also to add sunscreen on the rest of your body. The formula contains hyaluronic acid to improve moisture. It dries soft and lightweight which I really appreciate in a product that also protects the skin from the sun.

Love a subtle glitter!
Color: 1 Pack, Color: 1 Pack
I am a big fan of glitter for going to events with my little daughter. She loves wearing glitter as much as I do. We both wear sunscreen, and I was interested in this because of the SPF promise. I also liked the idea of a sheer mist. I like to use glitter as a way to make up for not having a tan so I can still have a sort of sunny glow. I am not sure how I feel about this as an spf product. I prefer to put on serious cream sunscreen and I would just use this as a touch up mist, or cosmetic refresher. The mist is watery up closely sprayed but it is light and weightless misted on from an appropriate distance. The dried mist on my skin does have a sort of barrier or feel of a sunscreen over something like a gel. There is a slight tack till dry but very subtle. My sunscreen and makeup was fine under this mist. I do use mists to give my skin a natural texture so most of my products look good with a mist setting finish. The glitter is super subtle, but noticeable if you focus on it. In a low light setting I can see speckled glitter, and in direct sunlight. Just not clubbing or parade level body bedazzling glitter. I actually really like the fine glitter effect. There is no fall off, and the glitter washes off super easy. My skin feels very happy and hydrated but not bothered by a coating or layer. There isn’t really an aroma, I swear there is when I mist but then I smell nothing on me but a faint notion of some product. Not powdery but a mild lotion like note. Very hard to detect unless you are literally nose to skin sniffing. I think for the price this is a great fine glitter mist. I might continue to use my own sunscreen and not rely on this as a barrier. I take spf pretty seriously as a woman in my early forties. Overall I am really happy with this as a casual mist and I would buy it again to just wear because I like the texture and the effect. The box did have unfortunate choice of colors for reading but up close I was able to read the ingredients and information. The bottle is pretty cute, and the mist nozzle pumps well without sticking or getting gummed up.

Lightweight sunscreen mist with a subtle glow
Color: 1 Pack, Color: 1 Pack
I like how easy this sunscreen mist is to apply. The spray feels light and refreshing on the skin and dries quickly without feeling heavy or sticky. It leaves a hydrated, dewy look that works nicely on both the face and body. The fine mist makes it convenient for quick reapplication, especially when spending time outdoors. Another thing I noticed is the subtle shimmer that gives the skin a soft glow in sunlight. It is not overly glittery, just enough to add a little radiance. The formula feels weightless and comfortable, making it easy to layer over makeup or use on bare skin. Overall it is a convenient sunscreen option for beach days, festivals, or everyday sun protection.

Beautiful but smells a little fishy at first. Thankfully the smell dissipates fairly quickly.

Lovely shimmer, but lingering scent and uneven mist are disappointing
Color: 1pc
I love the shimmer in this. And I love that there is spf. But the spray nozzle doesn't provide a fine mist, it's more like a splatter so it's hard to apply evenly. There is also a lingering scent that I find a little overwhelming to have directly on my face. I want to love it, but I'm giving it 3 stars for those issues.
