I've been shopping from SN for a while, but it's mostly for lippies and blushes, and I thought that I should try the foundation and other face products

My dream face would be flawless radiant skin, but unlike a select few, I've not been blessed with such good genes. My country is very hot and humid, so makeup always feels like it's sliding off or separating and I always get shiny in my t-zone no matter how much powder I apply. I also struggle with adult acne and have red and dark brown marks on my face, and enlarged pores.
What would you recommend? Im really desperate for some help!!
