Face acne clogged pores issue. Care!

I am having lots of acne , clogged pores on face and it's even leaving so much darkness on face after going , i even used to have acne back then too but now it's increasing so much like even in winter , I have from this year started using dot and key's skincare products it seems not to be suiting me , I have been using their vit c moisturizer and their watermelon sunscreen + on some day in week I was using minimialist alpha arbutin , after almost 2 months I saw no recovery in face even lil worsening so I switched to dot and key niacinamide moisturizer instead with vit c sunscreen + on certain days minimalist salycylic acid serum. This literally ruined my skin and I started getting even more acne , also I don't get usual acne they're like clogged pore they don't have blood etc in it they're like dry but when they goes they leaves some mark mostly darkness on face , i stopped using serum them now I am normally using only moisturizer and some other sunscreen . Acne seems not to much care
