The BEST sunscreen I've found
Style: SPF 50, Size: 3 Fl Oz (Pack of 1)
This is my MUST HAVE sunscreen. I've had almost every type of skin cancer (thankfully, caught early), so I NEED good sun protection, especially on my face. I have very fair skin. This product leaves a bit of a white cast, but after a short period of time, that white case is absorbed. The white cast of a mineral sunscreen might look chalky on a person with darker skin. The BEST thing about this sunscreen is I can put it on my eyelids and under my eyes, it doesn't irritate my eyes AT ALL. The other well-known sunscreen I used for a long time really made my eyes sting if a bit got into them. This is my favorite sunscreen of all time.

Solid mineral SPF with light coverage effect
Style: SPF 50, Size: 3 Fl Oz (Pack of 1)
I’m used to La Roche-Posay’s chemical sunscreens, so this was my first time trying their mineral version. The texture is actually quite nice for a mineral formula. It spreads evenly and doesn’t feel gritty or chalky. That said, it does take a bit longer to fully absorb compared to chemical SPFs. I’m already very pale, and I still notice a slight white cast. It’s not extreme, but it’s there. To be fair, most mineral sunscreens tend to do this, especially those using zinc oxide and titanium dioxide. Interestingly, on my skin it almost behaves like a very light tinted sunscreen. It slightly blurs and softens the appearance of minor blemishes and redness, which I appreciate on minimal-makeup days. It provides broad-spectrum SPF 50 protection and feels gentle on sensitive skin. I haven’t experienced irritation, pilling, or breakouts. It layers reasonably well over moisturizer but benefits from being applied in thin, well-blended layers, which adds some time to my morning routine so it's a little inconvenient. Overall, it’s a solid mineral option with good protection. Just expect a bit more blending time and a subtle cast.

Great for pregnancy (or regular use)
Style: SPF 50, Size: 4.05 Fl Oz (Pack of 1)
I searched far and wide for a safe mineral-based sunscreen for pregnancy. I settled on this one and I was not disappointed. It saved my skin from a lot of sunburn this summer! As other reviewers mentioned, it is harder to rub into the skin and can leave a whiteish tint, but that’s a small price to pay for a pregnancy-safe option.

Terrible, look like a ghost
Style: SPF 50, Size: 3 Fl Oz (Pack of 1)
I love La Roche-Posay but unfortunately, I finally came across the first product I truly hate from them. This product is a complete white mask on your face and does not settle in at all. You’ll be walking around looking like a ghost all day and it gave me a mild irritation to my eyes.

Leaves white cast, works okay under makeup.
Style: SPF 50, Size: 3 Fl Oz (Pack of 1)
First time using this sunscreen. I have very sensitive skin and thought since my skin tolerates their cleansers and moisturizers surely it should tolerate the sunscreen. So far so good. It’s very calming on my skin (maybe because of the zinc), but it leaves a noticeable white cast especially if you have dark skin. I wear mine under makeup and have a separate sunscreen from another brand on days where I don’t want to wear makeup. The white cast actually acts as a blank base and helps my foundation to lay well. A tip I learned from makeup artists years ago. Sunscreens that leave a white cast cancels out your natural color and acts as a corrector, concealer and foundation to lay better and look more like skin. Think of it like painting on a blank canvas. The texture is not lotion like and is actually quite thick. make sure to moisturize well before apply this sunscreen. I’ll write an update if I notice any negative issues, but so far I’m content with it because of the purpose I'm using it for.
