These Are the Skin Care Products Dermatologists Won't Travel Without

"My one must-have travel product is a vitamin C serum. It's like a little black dress: everyone needs one in their wardrobe because it makes us all look so good with so little effort! Vitamin C is a powerful antioxidant that helps even out your complexion, add radiance and prevent fine lines. I love it because it's cosmetically elegant, easy to layer and plays well with other products. Youth to the People Superfood Firm and Brighten Vitamin C Serum, $62, does the trick: it not only contains the benefits of vitamin C, but it's also packed with peptides and hyaluronic acid to boost skin health and hydration. Just one important thing: vitamin C doesn't like bright light, so keeping it in dark places and containers helps it work better."
