I used to suffer from widespread acne but I cleared it thanks to Benzoyl Peroxide. However, ever since my acne cleared I have suffered from a combination of very oily skin and enlarged pores, many of which are deeply clogged and keep forming blackheads and/or whiteheads. I'm only 19 but I feel like my skin looks really old.

I cleanse, tone and then moisturise every morning and evening (I will sometimes use benzoyl peroxide in areas where I have spots). In addition, to help breakouts and to attempt to unclog pores I sometimes use a clay face mask and an exfoliating face scrub and now only allow myself to have cold showers to avoid irritating/enlarging pores. However, none of this seems to help and my cheeks and nose are covered in oily pores that are continually getting blocked up. 

 I am debating on whether to replace my moisturiser with jojoba oil, because I feel as though my skin's oil production is not decreasing and that moisturising is only increasing my face's oiliness and shine. (which doesn't help the appearance of my pores). 

I am looking for advice on how to unclog these pores completely and minimize their appearance. I would really appreciate advice concerning moisturisers/oils and the use of Retin-A,  BHA exfoliators and other skincare products. Thank you in advance
