I have really sensitive skin, so I’m picky, but this product has been such a standout. It doesn’t irritate my skin at all (it actually helps my redness) or leave a white cast, and it is perfection under makeup. 10/10 for me.
I have tried a lot of sunscreens, mostly due to the fact that I have sensitive/reactive skin and need to use gentle, moisturizing products to avoid irritation. This serum has been a dream to use as the final step in my routine. I love the silky texture, how easily it spreads onto my skin and that it doesn’t pill under makeup. It has all of the things I’m looking for in a mineral sunscreen plus some great skincare benefits. My boyfriend has also been using it and loves it too. I’ve already ordered more and will recommend it to my family and friends.
I use this every day and I’m in LOVE with the formula. It’s so smooth - feels delicious on my skin
I’ve been using SunDay for over two weeks, and I’m genuinely impressed. It has a lightweight, silky feel and a subtle tone-up that makes my skin look more even and less pink. It layers really well under makeup (I often use a green corrector) and doesn’t feel greasy.
this serum blends in easily and works well under makeup. I have very sensitive skin and this product has not caused me any issues.
