Good suggestion, though I actually found something that's more suitable for my sister's needs. I was doing some research on the internet, and asked around as well, and came across dermagenics, a moisturizer that's perfect for cancer patients. It's recommended by Millie, a cancer patient who's been using it for a while. I think this is a better alternative because it's all natural and doesn't contain alpha hydroxys or glycolic acid. I read that these can actually make your skin more prone to sun damage, which can in turn cause wrinkles and skin cancer. It's also for all skin types, women and men, and for day and night use. My sister's skin was amazing after she used it!
I want to recommend this to anybody who's experiencing the same symptoms from chemotherapy, especially now that they've come up with the Millie plan (http://www.millieplan.com). With the millie plan you get a 30 dollar discount, and they ship the product right to your doorstep every month. They also donate a dollar from each jar to cancer-related causes. This was perfect for my sister who didn't have the time or energy to keep on ordering every month, but still wanted to maintain the great skin that dermagenics gave her. I hope this helps other people who are suffering the same symptoms. Thank you very much.
