Serum-like texture, mineral SPF wizardry

JujJuly 27, 2025

The media could not be loaded. How is it that more people don’t know about this?! Short version: The bottle isn’t huge, but if you want/need mineral over chemical sunscreen but have an hard time with the weird mineral texture, have very sensitive skin, and/or are acne-prone, it’s VERY worth it (and it’s on sale right now, so I might get a couple more bottles while I can…). I am what you might call a “skincare junkie,” but having been on Accutane for 8mo now, there’s not much leeway skincare-product-wise. Everything I use needs to be gentle, simple, and very moisturizing, but I will not use the most-recommended CV cream as it has a very comedogenic ingredient combo, so it did take a bit to find alternative products that work for me. I’ve been using a different (chemical) SPF on my face, but a recent dose increase has caused extreme sensitization to the point that basically anything besides petroleum jelly makes my face burn like crazy until I have to wash it off. Sunblock seems to sting the most severely, which is super frustrating, considering SPF is the most crucial bit of skincare (especially with intensified photosensitivity). I found this searching Amazon specifically for a Korean mineral face sunscreen. I ran the ingredient list through INCIDecoder to check for irritating & comedogenic ingredients, and it looked great (pics included). I cracked it open as soon as it arrived — I braced for impact, but it did not sting at all :,) The texture is like a lightweight, liquidy serum with a natural-glowy finish. It takes zero effort to rub in and has very little to no white cast. While I am extremely pale and can’t reasonably speak to how this would do on darker skin, I can confidently say it definitely did not leave behind any visible zinc-y white streaks or blobs, and it doesn’t “soap” (get whiter) the more you rub it in, so I imagine it would do better than most mineral sunscreens on a wide array of skin tones. It’s not that thick white peanut butter textured crud we had to use as kids, by a long shot — not thick, slimy, greasy, difficult to spread/blend, etc., and does not pill. As previously stated, it does have a glowier finish, which could end up looking a little ~sweaty~, especially on oilier skin, but it’s grippy enough that I imagine it would hang onto setting powder very nicely if that’s a concern. I layered this on top of serum & moisturizer, as my skin is drier-leaning (regardless of Accutane), and it feels great, not actively drying me out or melting off etc. I’m overall really pleased with this stuff, and still amazed that it’s not a known quantity. Not gonna lie, just ordered 3 more tubes of it as it’s currently on sale for $16.50 — not like I’m going to stop needing SPF, after all, and mineral is best if you can find some that works for you. Highly recommend!! Personally very glad I stumbled on it. Read more

Really has no white cast!

MariaJuly 30, 2025

It's really a no-white cast mineral sunscreen! I couldn't believe it as many claim to be but still have some cast. It's very lightweight. May need to apply a bit more than with other thicker formulas to ensure full coverage and protection. It does have a scent, kind of "plasticky", that lingers a bit. But after a while it goes away. Dewy finish. If you have no issues with scents this sunscreen is a great option. I have hormonal acne prone sentive hyperreactive skin and it doesn't break me out or cause irritation. If you have hypereactive skin like me I would recommend waiting 1 or 2 minutes before layering with the rest of the skincare you might use. It also looks good under makeup, no flaking. Read more

Glowy & no white cast

cjOctober 27, 2025

I prefer Korean chemical sunscreens, but now that they are restricted in the US, it has been hard to find good light weight sunscreens that don’t feel super thick/heavy and don’t leave a white cast on my tan skin. This is one of the best ones I’ve tried so far because not only is it very light weight and doesn’t leave a white cast on my skin, it also leaves a nice subtle glow (not greasy looking). I wore it during the summer and it did not break me out at all! I have dry/combo skin and it was perfect but I probably would not recommend it for oily skin. It is also one of the few sunscreens that didn’t irritate or sting my eyes at all. Read more

Korean sunscreen

Very nice product. Goes on clear but has a little odor…not bad. Read more

★☆☆☆☆

Oxidative and reacted on my skin.

Manisha dhimanOctober 25, 2025

I did not like this sunscreen at all. It oxidizes after few minutes. My skin reacted to this even though I have pretty good skin. So I returned this product. Never buying anything from this brand. Read more

Love this Stuff

SarahNovember 24, 2025

I love this stuff. It is a very thin, serum consistency. It's very easy to rub in and doesn't cause any white cast even though it's mineral. Will definitely be repurchasing. Read more

Amazing

FranciscoMay 7, 2025

I have oily acne prone skin and saw reviews on this ordered it and it didn’t dissappoint. It blends in easily with my skin tone which is brown and doesn’t peel. I like that it doesn’t leave shiny finish its like a matte to normal glow really minimal and its mineral. The only thing is the size is small and slightly expensive I wish we got a bigger container for this price but its the best sunscreen Ive tried. No whitecast, no oily finish, its easy to blend, and minimal sunscreen smell. Read more

Average sunscreen, scent intolerable

Linda SuDecember 9, 2025

It's not a bad sunscreen, not greasy but it's very hard to get over the scent. It smells like a wet towel. I threw it away after a few uses because the scent became intolerable to me. Read more
