Tretinoin and Accutane?

I just realized that a few months back, before I started accutane I was prescribed Tretinoin for my acne and I stopped using it and have some left over. But isn't that a retin-a? Something I can use for red marks? I really need to know if it would be safe to use that while I'm on accutane or not! And would it help with all my nasty red marks???
THANK YOU!

Cleansers

Does anyone have any suggestions for the BEST cleanser to use while on Accutane to better prevent and clear up breakouts? (Hopefully there is such a thing... I never have much luck)
I'm about a month into my course and I break out a bit about every other week I wanna say? This one right now could be due to my period though... ugh. But yeah! If there's a good cleanser that I should use that keeps things looking their best then it'd be greatly appreciated! I don't really have just ONE actual good cleanser that I'm using right now, so I'm on the lookout for something new! Thanks!

Nose blackheads

Hey everyone. I'm almost a month into my course and right now my nose has a lot of blackheads I think? (which is not normal for me) or they might just be clogged pores and a lottt of little bumps everywhere! it's not smooth anymore! does this happen to most people? and what can i do about it? I was thinking about those pore-unclogging strips but I don't know if they'd be okay to use...
Thanks a bunch!

Scars getting worse

So I'm almost a month into my first Accutane course and i've been noticing that i'm getting more (slightly indented) scars and my i think i have more red marks (though i possibly couldve made them worse by being in the sun). but these scars are so scary! i mean they aren't HORRIBLE but i've never had them like this before. i used to have just a few but they're really visible in florescent lighting and whatnot. my face jsut looks bumpy or rough, like dirt or something haha. i don't know how to explain it. but what can i do to make it better?! i've been using bio-oil for a few weeks for my red marks but i don't think it's been doing anything so i'm willing to give that up. i heard a few things about extra virgin olive oil... anyone have anything to say about that? or vitamin C??? i just don't know, i need some guidance!
please and thank you

RED lips!

Hi everyone, I'm about 23 days into my first course ever and things are going pretty well I love not having to wipe the oil off my face ONCE all day! It's amazing! But within the past couple days my lips have gotten really red and i hate how they make me look like i'm wearing lipstick or something! i never wear lipstick so it looks weird on me haha. does anyone know how long this will last or if there's anything to get them back to their normal color?! I'm going to buy my first tube of lipgloss that i've had in years tomorrow, in a light shade just to counteract it. haha ridiculous!
anyone, help me out! thanks
