help a girl out please im losing my confidence because of my skin issues

background: 19, started using skincare products on nov 2023, has pcos (hormonal imbalance)

timeline: 2020-2021 all i have ever done to my face is use local moisturizers and basic soaps, i have also made my own face mask (egg white + coffee) and used ice every other day

no acne issues

2022-2023 i have no skincare routine aside from using local moisturizers (no sunscreen too)

acne issues (not frequent)

nov - dec 2023 i bought a sunscreen, the cosrx low ph cleanser and snail mucin cream, loved it (no frequent acne issues) i discovered the bioderm cream for my acne (once i applied it on my, the next day my acne is gone so it works) i discovered double cleansing so i bought anua oil cleanser and their toner pads, a few weeks after i bought their toner as well

feb 2024 i saw that salicylic acid is a good chemical to reduce acne so i bought cosrx SA cleanser

i broke out (thinking i was purging) and still kept using it (i was still breaking out)

but i thought it was just because of my hormones because i had my period this month (after 3 months) so i kept using it

may 2024 i stopped using the cleanser since it did nothing to my face aside from breaking out and i switched back to my low ph cleanser, however due to my frequent acne attacks, i had a lot of dar spots now which made me want to purchase a serum for my dark spots

i bought the ordinary niacin 10% (worst decision of my life) it made my acne worse and i broke out worse than i did with the cosrx

present 2024 i am not using cosrx SA cleanser and TO 10% niacin anmyore, currently im using senka whip premium cleanser (started 3 days ago) and anua peach niacin (started 1 month ago) and im hoping for good results

please check the photos for a better look at my problems and if anybody can help me i would appreciate it (tho i plan on having a dermatologist’s appt next month)
