Foundation Hit or miss during Summer?

I always get 2 foundies for whole year, one shade lighter and one shade darker and keep mixing them together to match my actual skin as it’s changing color each season. hope this helps

i live in a tropical country.. the weather here change constantly from dry to damp and cold rainy to hot sunny could be in least than 24h so i use the same foundation all year (tho i have a lot kind foundation.. i mean i use them depend on my mood not weather haha 😂) the only thing i change is the skin prep before makeup.. when i saw the sunny day i took the matte based with extra spf if i saw clouds i would use extra hydration (mostly would be a bit dry when it’s cold) or depend on my activity that day if i go out door going a bit matte skin prep with extra spf if i went indoor going extra hydration (since indoor mostly in ac ice cold)

I use bb cream all year round! I like how it's lightweight and has skincare benefits.

I'm in the UK and use a cc cream for day to day/work and a foundation just for nights out etc. I change my skincare however in the summer and use less hydration and a different moisturiser

I use the same stuff year-round. There's really nothing to help my oily, sweaty face lol I just avoid being out in the heat. It's not good for me.
