Love the scent
Scent: Tropical Breeze
This sunscreen has such a great scent and is easy to apply with no white cast. Skin doesn't feel clogged or sweaty. Easy to apply and distribute.
Like that it's a zinc oxide sunscreen that is doesn't leave a white cast and has a wonderful tropical scent. Wish it came in SPF 50 or higher.

ACTUALLY unscented! Finally!
Scent: Unscented
I have been on a personal mission to find a truly unscented sunscreen, as I have extremely sensitive skin and medical conditions that cause me to have skin reactions to fragrance. I have tested out 10+ different sunscreens and even in those that do not list a fragrance, can still have a strong smell or scent due to one or more of their ingredients. This sunscreen truly is UNSCENTED. I was even able to use it on my face today, which until now I have been able to do successfully with only one other sunscreen.
I have yet to try out this sunscreen in direct sunlight for a prolonged period of time, so I cannot speak for how effective the SPF 30 is for activities out in the sun, but I was able to comfortably wear it for walking my dog for 20 or so minutes while wearing a sun hat, which is normal use for me when it comes to sunscreen.
I will come back and update this review if anything changes as far as sun sensitivity or if any burning takes place.
Now for the cons: it felt a bit heavy or "stifley" on my face, but I have sensory processing issues so I'm sensitive, and there was pilling on my face hours later.
So far I would recommend this sunscreen and am stoked to have discovered it. It is my current go-to for my body sunscreen, and haruhara wonder black rice SPF 50 velvet finish sunscreen is my go-to for face sunscreen

Stunning daily SPF
Scent: Unscented
Hands down the best daily SPF I've ever used. It's not sweat/water resistant, so not great for outdoors, but for a daily moisturizing SPF lotion? 10/10. Minimal white cast, but it's a mineral SPF, so not zero cast. Not irritating at all, no hidden chemical boosters, no eye sting, does not cause my eczema to act up, and extremely moisturizing. Most mineral spfs leave me like a corn husk, but this one actually improves my skin's hydration. I wish I could give this more stars.
My only criticism is the brand's use of "clean" marketing language. This isn't a real term, it's just a marketing strategy.
The product itself though? Stunning.

Solid sunscreen, yummy scent!
Scent: Pear & Coconut Water
Easy to apply, blends in smooth with skin, and smells yummy! It worked well in the strong sun of Punta Cana, plus it's better for your skin than most sunscreens out there.

Gentle Cream Cleanser That Actually Works
If you’re specifically looking for a foam-based face wash, this isn’t one—it’s more of a cream-based cleanser. But honestly, that’s what makes it work so well.
It feels light, not oily, and leaves the skin smooth after washing. You don’t need a lot of product, so even a small amount goes a long way—especially if you pre-wet your face.
It might feel a bit different at first if you’re used to foaming or soap-based cleansers, but give it some time. After about a week of using it twice daily, I started noticing a difference—my skin felt clearer, and some pimples and spots began to reduce slightly.
Overall, a gentle yet effective option if you’re looking for something that delivers results over time.
