This may seem an odd question but today I used an organic sunscreen and after a few hours my tee shirt had turned pink around the edges of my neck where it was touching my skin. It wont even come out with bleach.
Is it possible that there are chemicals in the letrozole or palbociclin that might have caused my skin to react? It has not happened before and yet I know I have used this same product in the past.
Hmmm...interesting/mysterious!
I've not experienced anything similar but I happen to have a lot of experience with stains, e.g. just (i.e. yesterday!) restored a pair of my son's slacks and one of my daughter's childhood dresses from 20 years ago!
What I did was mix white vinegar and baking powder into a paste and scrubbed it into the stains then let it sit. Kept at it a for a few treatments until most disappeared.
The light red stains on my son's slacks were still visible, so I left the paste on a set them outside in the sun for while...which completely removed the stains!
Just my hopefully helpful household tip! 
Take a look at the active ingredients in your sunscreen. Avobenzone can cause pink-reddish stains on fabrics when washed in hard water (water with a high mineral content). Very hard to remove. If you are using a truly organic sunscreen product, there should not be any avobenzone in it. You may have to switch to another sunscreen with only zinc oxide and/ or titanium dioxide as active ingredients to avoid staining.
Well thank you! Yes 3% avobenzone. And I do live in a hard water area. Now I know what to avoid. I am very impressed with your knowledge.
Whoops! Never heard of that one. Worth checking the ingredients/compounds in the sunscreen.

Yes and apparently when mixed with chlorine such as in a pool it can cause cancer. It's also one of the compounds causing reef damage. I've been doing some research since Safety 1600 replied. It was an online shop that sells organic products so I'm going to follow up and look more carefully at ingredients now I know.
