BOJ sun serum review

I tried the BOJ sun serum last summer and immediately fell in love, but over time I realized it was making my skin look more inflamed by the end of the day 🙁
It goes on very nicely in my opinion and absorbs quickly, I would apply it either immediately right after cleansing or after toner (I was using peach slices snail mucin toner which I love)
When winter rolled around I stopped using it because my sunscreen felt like enough for the days when I worked outside / I work inside more in the winter months
When I started using it again I noticed that while right away my skin looks fine, it would look more irritated by the end of the day. I do reapply my trusty Goodal calming sunscreen mid way through the day most days but I know it's not that product causing the irritation
If anyone has more questions about the BOJ sun serum feel free to ask, I'm on my second bottle of it but am going to stop using immediately. My skin is sensitive/ combo so not saying it's a bad product, I wish it worked for my skin
Does anyone have a sun serum you love? I love the idea of sun protection as a first step to ensure I don't start working before I remember to apply it! (Sometimes I forgot to apply it after my moisturizer dries, and then apply at work after I realize I've been in the sun)
