Hey all, ill try keep this as short as possible which will be difficult but bare with me

, Ok i am 23 y.o. Ive been battling moderate/mild acne since i was 18 so about 5 years or so. My acne mainly was clusters of whiteheads (cheekbones) and blackheads (nose) aswell as pimples on the chin/mouth area. Anyway up untill i was 18 i really payed no attention to my skin and i didnt have that bad of a complexion , When i turned 18/19 i started a regime of washing my skin with all kinds of different products and what not . Anyway over time it slowly got worse and worse untill i went to my gp and he prescribed my doxycycline which i took for a while n they sort of worked but as soon as i come off the pimples would be back . SO i went to a derm my derm put me straight onto accutan dose of 40mg ed for 5 months. cleared my skin right up for a good 3 months now its back So im back on accutane at 20mg a day aswell as following my skin regime religiously which is shower in the morning (no products ) moisturise (cetaphil) , then of an evening wash(cetaphil) moisturise(coconut oil) . My question is could it be possible that im over washing my skin , i mean i remember when i was younger (teenager) i hardly payed attention to my skin and it was fine now i do everything for it and its a pain in the u no what . im thinking i might wash(cetaphil) eod or 3 times a week. I also have a huge problem with dry skin( i no accutane drys ur skin right out) But my skin is really dry around the cheeks,under the eye so dry its often red . Moisturiser helps. I hate taking accutane so any thoughts would be appreciated ??
Thanking you for ur time
i might also add i pay very little attention to my upper back/shoulders thier clear as. wear as i scrub my chest/face and they always seem to be wear im gettin pimples/dryness . its strange i mean were ment to shower right ?
