1 - I skip cream/lotion and go right for oil. I use grape seed oil or castor oil (latter is heavier) depending on the dryness factor. I don't know if that would help you... but basically, I oil my face right after I shower.... and it helps tremendously. I do under my eyes - over my cheeks... and my lips and around my lips. The other parts of my face seem fine. For my scalp, on which I got horrible horrible acne, I use hibiclens in the shower followed by a salicylic acid solution after the shower. I have had NO ACNE since. You don't want to use hibiclens on your face though... But I mention it in case that regimen might be helpful....
2 - The C is carboplatin right? I had the same side effect plus constipation.... There's really not much you can do. Chemo totally whacks your gut flora, and there's just plain not much you can do expect not eat foods that make it worse (like onions and garlic).... Sorry.... My better half also told me that I myself smelled kind of bad after a carboplatin infusion. Sucks rocks, that is for sure.
Now that I am recovering after my last infusion, which was an andriamycin and cytotoxin cycle, I am eating acidophilus and bifidus tablets in hopes of getting my gut flora back towards normal... I have no idea if it is working, but my gut seems to be coming back to normal. I do not think that taking it during treatment is very helpful... but it might be worth asking about.
Also, I took laxatives and stool softeners to help with the constipation, and they totally made it easier. That was recommended by one of my physicians.... Sennacot and some red stuff - colase or something like that.
A side effect with AC that I am currently recovering from - and this is embarrassing - is a very painful butt hole! [email redacted] Oh man it hurts to go poo! Just today, it seems to be easing off a little... I figure it's probably similar to the mouthsores, but just in that very sensitive and private area.... Wah!
I don't know if this helps.... You should definitely talk to your talk if you think anything is scary about your poo... Especially with the carboplatin... Or so they tell me.
And yes - these side effects are embarrassing.
One more is the overwhelming hot flashes I sometimes get! And I don't want to whip off my hat in the middle of a meeting! I just kind of prefer to keep my bald head covered.....
Good luck... Hugs....
