My love affair with The Face Shop The Therapy First Serum started when I received a handful of samples of this product when I went to Myeongdong in Korea a few years back. Korean skin care was still new to me at that time, so I had zero expectations when I first applied this on my skin. Basically, I just took a major leap of faith (to K-beauty) that this will not aggravate my annoyingly sensitive skin.
