Guys, This Serum Is Saving My Sensitive Skin This Winter

Here are two words that you may not have given much thought to before: skin barrier. But if you're the type of person who gets flushed easily, you might want to start caring for yours stat. 

Um, what's a skin barrier? Without getting into a full science lesson here, the skin barrier is the outermost layer of your cells plus everything that holds those cells together. Keeping it healthy will ensure that your complexion stays calm and hydrated—which is exactly where this serum comes in.

Formulated by Marie-Veronique Nadeau, a brilliant chemist (who suffered from acne and rosacea for much of her life) and Kristina Holey, one of the West Coast's most sought-after aestheticians, this serum is loaded with soothing ingredients like niacinamide and epigallocatechin gallate (a potent antioxidant found in green tea) that are meant to strengthen your skin barrier and reduce inflammation over time.  

From a strictly aesthetic perspective, I like its cooling, lightweight texture. It has a nice liquid consistency that absorbs quickly and layers under everything without leaving behind a sticky residue. It's also fragrance-free with no potentially irritating essential oils in the formula. And by golly does it make my skin glow.

I've been using it day and night for the past six months and have noticed my cheeks are much less blotchy and my overall complexion is more even toned—no small feat for someone who flushes at the slightest temperature fluctuation. The only caveat is that it is an investment at 90 bucks a bottle (but I take solace in the fact that I'm spending less on concealer now).
