Wow... I got goosebumps looking in the mirror on the last train. Is it because of the moisture?

Ugh! I just ran as fast as I could to catch the last train home from work and saw my reflection in the subway door. Actually, I had the heaviest overtime I've ever had, and I've been working in the office for almost ten hours, so my skin should be ashen, but I was surprised to see my face looking so much firmer than I expected. Normally, my face would be cracked and flaky like a rice paddy by this time, but this morning, instead of a pack, I just applied a moisturizer. Hydration I applied the dragon ampoule three times and it seems to be working. I'm so proud of my skin for holding out under the office air conditioning, and I suddenly became really curious about the limits of this moisture. The ampoule I used today was an unknown ampoule that I received as a sample a while ago, and as soon as I got home, I was going to search through my recycling bin to find the name. Does everyone have their own secret recipe for maintaining a glow even after hellish overtime like me? I can't stop wondering what products other people use to lock in moisture all the way to work on the last train home. I feel like I want to run to Olive Young if it's open right now and buy everything similar to it!
