I recommend having makeup wipes to cleanse your skin and remove any makeup. Then add an antioxidant serum/oil to your skin to protect it and protect from free radicals. Next, you'll want an emollient moisturizer to really lock in and add moisture.
A moisturizing facial spray may be a nice addition as well. And if it's a flight during the day, where SPF!
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
