Sixpack, I’ll be praying for you. I’m not familiar with the condition or disease you have, but I still remember what chemo did to my mother the last 18 months she was alive. She was diagnosed with breast cancer at 68 and we lost her at 76. Both of her breasts were removed. She didn’t really stand a chance at her age. Nobody could ever sell me on chemotherapy being good, not after I saw it turn my mother into a shell of her former self. She was a woman who was in top health and bursting with energy. She had her own variety of skills. You’re a very strong woman, I can tell from your posts which I always enjoy reading. You hang tough. this site wouldn’t be the same without you.
In rat studies, orally ingested Vitamin C (25mg/kg in rats) alongside intracerebral injections of fibrillar amyloid-β was able to reduce oxidative and inflammatory biomarkers (the former comparable to melatonin at 20mg/kg but weaker than vitamin E at 50mg/kg; the latter similar to vitamin E but less than melatonin)  although elsewhere in an older APP/PSEN1 transgenic mouse model injected with 125mg/kg vitamin C failed to find evidence for neuroprotection or beneficial changes in oxidation (despite slightly improving memory). 
Topical application of a cream containing 5% of an astaxanthin containing oil (% astaxanthin within the oil; µM final concentration) in otherwise healthy women at 1mL twice daily to the face for eight weeks was sufficient to reduce wrinkle and 'Crows feet' formation associated with improved elasticity of the skin.  Age spots were also reduced as assessed by normal and UV lamp photographs, and while there was no overall moisturizing effect a subgroup with dry skin appeared to see some benefits and TEWL (whole group) was reduced.
