Unexpected surprise

As my first Vit C product, this delivered all the wonderful surprises it promised on my skin. Its a great summer product as the coolness added to the skin after being refrigerated (as per box instructions) is great to wake up skin in the morning. Not sure if I want that in winter mornings though.
