I will always have terrible skin. Help.

Im turning 30 soon. My skin has always been horrible. Ive tried every product on the market from pills , creams,masks, prescription products, homemade remedies, to nothing at all.

My skin is so congested with blackheads. I could literally extract 50 in one day, and there would be 50 more tomorrow. Its not even really acne. Just blackheads under the skin. In my earlier years..people called me " alligator face".

It sucks because I would really be a beautiful woman if my skin wasn't so terrible. I dont even like looking at my SO in the face out in the sunlight.

I don't wear much makeup at all. Mascara. I dont sleep on dirty pillow sheets.

I started using "Differin" products here lately..but blackheads still forming everywhere. Chin and cheek areas.

Anyone know what this could be ? They basically are blackheads that are UNDER my skin(cant see black)..and if I squeeze hard enough, this nasty white sebum comes out. I know I shouldnt pick at them..but they will only get bigger if I don't get them out.

I need help.
