Solid Option for a Sunscreen Spray! Nice Even Mist!
Item Package Quantity: 1
I’ve been using the Naked Sundays Hydrating Glow Mist SPF 50+ and overall I’m really impressed. One thing I was a little concerned about at first is that it does contain alcohol, so I expected it might be drying. Surprisingly, it hasn’t dried my skin out the way other similar products have, which is a big plus for me.
The scent is pleasant and not overpowering. It doesn’t have that harsh sunscreen smell that some sprays do, so it’s easy to reapply throughout the day without feeling like you’re coating yourself in fragrance.
In terms of finish, it’s not completely non greasy, but it’s also not overly heavy. I would call it slightly greasy, but noticeably less so than most sunscreen sprays I’ve tried. It gives a bit of a glow without feeling suffocating on the skin.
One of my favorite things about this product is the spray itself. The mist is very fine and even, which makes application quick and easy without leaving blotchy spots.
Overall, it’s a solid option if you want a convenient SPF mist that feels lighter than most, smells good, and doesn’t leave your skin feeling dried out.

Glowing face with sun protection. No fuss, no muss!
Item Package Quantity: 1
Wow, I love this stuff. It does make your skin hydrated and glow with health while protecting it from the sun. No shiny oil, just glow, and best of all, no need to mess up your makeup reapplying sunscreen. You can use it to set your makeup for extra protection (I still use sunscreen under makeup). The mist comes out so fine and even, no drips or glob. The scent is light and fades quickly. The best I've dried out of all the other brands.

Lightweight and glowy
Item Package Quantity: 1
I’ve been using the Naked Sundays SPF 50 Hydrating Sunscreen, and it’s quickly become a staple — especially for long days outside and on the tennis court. The texture is lightweight and smooth, and it blends in beautifully without leaving a white cast or greasy feel.
What I love most is the finish: it gives a natural, healthy glow without looking shiny or heavy. It layers really well under makeup and doesn’t pill, even when I’m reapplying throughout the day. I also appreciate how hydrating it feels without clogging pores or causing breakouts.
Performance-wise, it holds up well during activity and sweating (which matters for me during matches). The packaging is easy to toss in a tennis bag for quick reapplication.
If I had to note one thing, it’s slightly pricier than drugstore options — but the quality and wearability make it worth it.
Best for: everyday wear, outdoor sports, and anyone wanting high SPF protection with a comfortable, skin-like finish. Would absolutely repurchase.

Stings! Waste of money! Doesn’t accept returns!
Item Package Quantity: 1
Very disappointed with this spray sunscreen.
Although I’m usually not sensitive to sunscreens or face creams in general, this product made my eyes burn and tear up so much and so fast that I’m not able to use it. Such a waste. I even tried applying while covering just my eyes to avoid that area and it still stings. And it also goes on greasy, definitely not cute glowy looking. It is not a flattering shine. For the price I’m very disappointed and even upset that I didn’t notice before buying that you cannot return it. Don’t waste your money.
