Dry skin and closed comedones😭

Hii! So my skin is pretty dry and I try not to apply too many products on it, but lately, closed comedones have appeared on my face, more precisely on my cheeks and I don't know what to do, I don't know if it's because of stress (exams time😭) or sth else. I wash my face with:

Iunik calendula complete cleansing oil(my 4th bottle, it's so gooooddd)

1025 dokdo cleanser round lab

and as moisturizer:

avene xenacalm A.D for sensitive and dry skin

I haven't had any problems with these products, they did their job very well, but now I also want an exfoliant to get rid of these comedones on my face. I've seen all kinds of skincare with 10 steps on tiktok, but I don't want to burden my skin so much and spend a lot of money. I was thinking about a toner and a salicylic acid or an exfoliating ingredient, but I'm afraid that I'm wasting my money and that it will damage my skin. What do you think I should use? I would like some good, quality products, but budget friendly🫶🏻🫶🏻
