The product itself is lovely - it's a pretty light blue colour, and I like the smell (I did notice another reviewer said they hate the smell, but I really like it! And in any case it doesn't linger once you put the product on).
This serum has a noticeable effect on my skin - it's quite hydrating, and helps with any redness. The product absorbs quickly and fully, and my skin feels really soft after I use it. I usually use it in the morning after cleansing, followed by moisturiser and sunblock (or just sunblock).
