When I went to Hong Kong a few months ago, I desperately needed to get to the spa at my hotel (Intercontinental). Not that I'm OCD about it but long-haul flights can take a toll on your skin so I'm always looking for quick ways to replenish the loss of hydration (fact: cabin air on planes is drier than the Sahara).

As soon as I arrived, I booked a treatment at the spa for a facial after an hour of spending time with my best friend, H20 (in the form of drinking and swimming). The facial did wonders for me and I was excited when, as a parting gift, they gave me an ampoule of Kerstin Florian's Rejuvenating Pure Vitamin C. Kerstin Florian is a brand based out of California and the product-line has expanded like wildfire in the past few years, now with its own men's line.

I never really go out of my way for anything more than the basics, not to mention that most of the products that I use on a daily basis (or try to) already contain Vitamin C. So it was nice to have this supplementary addition for the week.

Kerstin is essentially ascorbic acid (Vitamin c) in a small tube so it's a highly effective antioxidant treatment that helps stimulate collagen product and promotes elasticity. And it feels refreshing on your face (before you apply moisturizer). While it has nothing to do with locking in moisture or rehydrating the face (plain and simple, guys, it's all about the H20!), I was happy to use this just to know I was getting that extra dose of antioxidant. I definitely would never go out to buy it (especially at $112) but when it ends up in my hands, I'm sold.
