hmmm
you say you have dark spots, you totally totally need a sunscreen to reduce those dark spots and prevent even more dark spots, spf 50 minimummmm
for your very oily skin, you need a good cleanser that has mild exfoliants (that way it removes the dead skin, and wash off the extra oil anddd unclogs your pores) inside and use it twice a day,,, and you need an oil cleanser for night
you will need a moisturizer with niacinamide, it helps balance the oil production
and start superrr simple
morning:
cleanser with a mild exfoliant (lactic acid, mandelic acid, papaya...)
moisturizer with niacinamide (search for this ingredient its super good!!)
sunscreen (MINIMUMMMM spf 50)
night:
oil cleanser (using an oil cleanser first is called double cleansing,,,it helps remove the sunscreen and it removes the oil debris from the skin (it also removes blackheads and whiteheads))
cleanser
moisturizer
alsooo make sure your moisturizer isnt very heavy, cant reallyyy assess your skin to check if you have something called fungal acne but try to not get a moisturizer with heavy oils like shea butter or coconut oil
