Have a short business trip (30 hours) to Frankfurt in June....what skincare products for a DRPW would you suggest that I buy? (only thing I have to be careful with is my neck, it is sensitive)

I have heard before that La Roche-Posay Active C is a good buy over there? Would love some good deals/products and I would like to research them before I go.

Thanks for all your help....
