Nice everyday sunscreen

Got the Mineral Face Sunscreen a week or so ago. It's really nice, not greasy at all which is a big plus for me. My skin usually hates sunscreens but this one felt good. Shipping was okay, took about a week to get here. I'd probably get it again when I run out.

Good SPF, quick shipping

I ordered the SunDay Invisible Defense SPF 40+ and a Post-Sun Recovery Cream. The ordering process on the website was straightforward, and I received an order confirmation almost immediately. Shipping was surprisingly fast, it only took 4 days to reach me in California. Packaging was secure, no leaks or damage. The SPF itself applies smoothly with no white cast, which was a concern, and the recovery cream feels very soothing. I also had a question about layering with makeup, and customer support replied to my email within a few hours with helpful tips. Overall, a solid experience with quality products.

Decent value on a bundle

I was looking for a new daily SPF and saw SONNI's SPF Skincare Bundles. I went with the one that included the Daily Face SPF and the Body SPF 50+. The bundle price seemed like a good deal compared to buying them separately. Plus, I got free shipping since my order was over $50. I'm always trying to save a bit where I can, and this felt like a smart purchase. The products are good quality, so I think it was worth the money.

Consistent quality as always

This was my third time ordering from SONNI. I've been using their SunDay Mineral Serum SPF 50+ for a while now. This time I also added a Travel Size SPF. Like my previous orders, everything arrived on time, about 5 days to reach me in Texas. The product quality is consistently good; the serum still goes on smooth without a white cast. It's why I keep coming back. They're reliable.

Good product, slow delivery

I bought the Broad Spectrum Mineral Sunscreen. The product itself is good, no issues there. Delivery took longer than expected, almost 9 days. It finally arrived well-packaged.

Love the Tinted Mineral SPF!

Oh my goodness, I just received my Tinted Mineral SPF and I absolutely love it! The color blends perfectly, and it doesn't feel heavy on my skin at all. I've been searching for a tinted SPF that actually works and this is it! It arrived super quick too, which was great. I'm definitely going to tell all my friends about this brand and I'll be back for more very soon!

L Laura Brooks 2 months ago
Nah, I have pretty fair skin and it blends in totally fine. No white marks for me.

Is SONNI actually a real brand or like, some influencer thing? Saw an ad but can't tell if it's legit.

W Wendy 1 month ago
