chapped lips and dry skin is definitely a thing, though if you stay hydrated and use chapstick (or just moisturize) you'll be fine. liver damage is a potential side effect so any dermatologist you go to will want to monitor that very closely and adjust your dosage accordingly to ensure that no serious damage is done.
alopecia will only really occur if you were dealing with significant hair loss beforehand, otherwise it's not common and anything you lose will grow back once the treatment is over. there's no evidence for stunted growth from accutane as far as I'm aware. before you start accutane you're legally required to read a very in depth pamphlet of all the potential side effects that may or may not occur, including ones with just the tiniest bit of evidence to them, and stunted growth isn't even mentioned. I haven't experienced dry eye at all personally, but I assume keeping hydrated helps with that.
I can't make a good observation on how accutane affects depression/nervousness/anxiety because in the time period just before I started accutane I was literally about to get expelled from my school under false pretenses, so that was the absolute peak of my anxiety and nervousness (the end verdict was that I did nothing wrong and there was no punitive action against me at all). I've technically gotten less depressed/anxious since then but I can't make a concrete statement on how accutane affected it
I started on a 20mg a day dose for the first month, then went up to 60 mg, and am now on 40mg for the rest of the treatment
