Finally — A Truly Sheer Mineral Sunscreen for Dark Skin
Size: 1.7 Fl Oz (Pack of 1), Style: SPF 50 Liquid Drops
As a melanated Black woman, finding a truly sheer mineral sunscreen is usually a whole struggle, but this one from Cetaphil surprised me in the best way. It goes on sheer with no weird gray or purple cast, and it’s absolutely dark‑ and brown‑skin friendly. No irritation, no heaviness, and it’s not greasy at all. It melts into my skin so well that it feels like nothing is there.
If you’ve been hunting for a mineral SPF that actually works with deeper skin tones instead of fighting against them, this is absolutely worth trying.

Just as good as the expensive product
Size: 1.7 Fl Oz (Pack of 1), Style: SPF 50 Liquid Drops
This product is almost exactly like the one made by a company that starts with "Clin" and rhymes with "eek". Just like the expensive product it doesn't have a lot of fillers. It is in a liquid base that is easy to spread over the skin and doesn't leave a heavy or oily residue, so you can wear it over moisturizer or rosacea medication, and/or under makeup, which is why I love it. It a fraction of the price of the other product, only $11 for 1.7oz vs $37 for 1oz, and it is more water resistant and stays on better. But there are a few things I want to share so that people have realistic expectations.
This type of product is a physical sun block, which means it works by spreading a thin layer of a mineral such as Zinc Oxide or Titanium Dioxide over the skin which shields the skin from the sun's harmful radiation. This particular product contains Zinc Oxide, which is a white powder that is often used in diaper rash cream as a skin protectant. You can even ingest it as a Zinc supplement. So there is a lot of evidence supporting the safety of Zinc Oxide.
This is not the case for chemical sunscreens that contain Oxybenzone, Octinoxate, Avobenzone, and the like. There is growing evidence that chemicals like these are harmful to people and the environment, specifically coral reefs. Some of these chemicals are even banned in Europe and Australia. Because of these concerns many people are moving away from chemical sunscreens and are switching to Zinc Oxide. But there is a downside to Zinc Oxide.
ALL sunscreens based on Zinc Oxide and/or Titanium Dioxide cause a white cast to the skin to some extent, that is how they work. You can minimize this by spreading the product in a very thin layer, which is easier to do with this product because of the thin consistency. But the white cast is still there no matter what. If the white cast bothers you, keep in mind that it means your skin is protected. You can add tint/pigment drops to the product to cover the whitish cast, or you can put makeup, tinted moisturizer or face powder over it to disguise it, but you can't avoid the whitish cast without using chemicals that are harmful to the environment and probably people too. Keep that in mind if you decide to try this product.

Excellent sunscreen for fair skinned faces, but not a matte finish as claimed
Size: 1.7 Fl Oz (Pack of 1), Style: SPF 50 Liquid Drops
✅ PROS: lightweight, skincare ingredients, protects very pale/fair skin in summer desert sun, does not irritate sensitive skin, does not clog pores, hydrating, doesn’t leave a high shine look like most similar products
⛔️ CONS: does not have a matte finish as it claims (more of a satin finish), it is oil free but if you are prone to oily skin it will not prevent the oiliness from showing, can be used as a primer under makeup applications but not nearly as good as an actual cosmetics primer
⭐️ WOULD BUY AGAIN ⭐️
Cetaphil Sheer Mineral Liquid Sunscreen works great for protecting my face: I have very pale/fair skin, I can be quite sensitive to skin products (as well as having mild rosacea) but this doesn’t irritate my skin in any way, and it has never clogged my pores or caused breakouts. This sunscreen also contains skin care ingredients so it doesn’t just protect your skin but also makes it healthier.
However, I do have combination skin - forehead in particular is prone to oiliness. The product claims to be a matte finish for oily skin and for under makeup application as a primer. The finish is not matte on my skin, even with a freshly cleansed face there is still some sheen - BUT it’s very subtle and a far cry from the shiny look of most other affordable sunscreens. While I can’t argue that it can be used as a primer under makeup, it doesn’t give the same quality skin prep for cosmetics the way an actual makeup primer does.
Even if you are prone to oily skin as I am, I still recommend Cetaphil Sheer Mineral Liquid Sunscreen for the face. It’s great quality, and protects very pale/fair, sensitive skin very well. I live in a desert area of Southern California, and I’ve never had a burn or even hints of a burn while using this product. Be sure to follow the directions and reapply every 2 hours to keep your skin safe and healthy!

Sun Protection, Clogged Pores Included
Size: 1.7 Fl Oz (Pack of 1), Style: SPF 50 Liquid Drops
While this sunscreen is lightweight, sinks into skin nicely, protects against sun damage very well, is truly affordable, and has a residue-free finish, it is not non-comedogenic as advertised. After using it daily for three weeks on my face, throat, the back of my neck, and ears it caused clogged pores on my nose, chin, and forehead and acne on my cheeks, ears, and hairline on the back of my neck. It also increased the overall oiliness of my skin. I did not change any of my other skincare products, usual daily sun exposure, diet, exercise, have health or medication changes, etc. during use, so this sunscreen is the culprit.
For reference, I am in my late 40s and have combination skin on the drier side that can be sensitive. I also have psoriasis but had no active patches while using this product. Before applying the sunscreen, I used an acne cleanser with 2% salicylic acid (currently using Cetaphil's new one), Cosrx 6 Peptide Booster, CeraVe Vitamin C serum, and then Vanicream Facial Moisturizer, letting all products absorb well for at least 10 minutes before applying the sunscreen. (I have used this same routine for over two years with excellent results.) Then, I applied two finger lengths of the sunscreen to my face and neck, another to the back of my neck, and a decent-size dab to my ears.
The sunscreen melts in quickly and leaves a slight white cast initially, but it dissipates quickly. I'm very fair, however, so this may just be my coloring. In aminute or two, the sunscreen is dry to the touch and ready for makeup application, for those who wear it. I haven't given the sunscreen a test drive with makeup since I prefer not to wear it. The finish is satin-like on my skin, not matte as advertised or shiny as mentioned by some reviewers. My skin experienced some oil breakthrough after a couple of hours, but that's typical for any sunscreen. It was more than the Korean brands I prefer with chemical UV filters, however, even ones that are more moisturizing.
Unfortunately, this is another American sunscreen fail for me. I'll use it up on my arms and legs. Oh, one final note: some folks are whinging about the size of the bottle. It holds 1.7 ounces of product in a very convenient, purse- or pocket-friendly size. 1.7 ounces is a standard volume for many brands of both American and Korean sunscreen, and this is actually a relevant selling point since it's not an unwieldy tube. Go by the weight when buying liquids, folks!

Worked well near the equator
Style: SPF 50
I bought this product because I was going to be in the field for a month, outside, every day, all day, in Tanzania at high altitude. A severe sunburn would be hard to treat in the remote area we were in, but also I am very careful about protecting my skin from aging. I had to have mineral based sunscreen because as a whitewater kayaker I know it’s the only truly water resistant kind and it was going to be sweaty. And since I knew I was going to be putting it on every day, and we didn’t have running water in the field (bucket showers only) I didn’t want it to feel gross. (I really wanted to try the spray but I didn’t want to put anything pressurized in my luggage.) And I had already discovered the Coola face sunscreen (30spf version) which had impressed me with how silky smooth and not greasy it is. Now this IS greasier because it is a higher SPF. BUT I think this product is as good as you’re going to get with the protection you’re getting. Like I said, I’m a white water tiger, so I have used a LOT of mineral sunscreens. This was hands down the most comfortable one I’ve used. And it was effective. I didn’t burn once—only time I did burn was when I forgot to put it on one day toward the end of the trip, when we were out for just a couple hours—and I got the first 2nd degree burn I’ve ever had in my life. That was what this stuff had protected me from, all day every day, the entire trip. I did tan a little but I think that was mostly from the few times I was not covered during short bouts or it was cloudy. For my face I used the Coola 50spf face product.
