Although it has a powerful and potent blend of active ingredients, Saint Jane Beauty The C-Drops (£73) feels quite gentle. My skin did not feel tingly or show any signs of irritation while using this serum. In fact, it even calmed down the previous irritation that I had on my eyelids and neck. After a few weeks, I noticed an overall improvement in my skin, specifically a softer, more even-toned complexion. I looked more radiant like I was glowing from within. It's a nourishing serum that is great for all skin types, but I highly recommend trying this out if you have dry or reactive skin.
