I've tried lots of vitamin C serums and this ranks above them all. The oil quickly sinks in and has had a brightening effect over time. I'm now trying it with the eye wateringly expensive oil from the same brand. It's a good combination. Get them both on promo and the pay out isn't (quite) so painful.

I’ve been using the C drops for a few months now and my skin is truly glowing. The skin on my (mature!) neck has definitely improved. I use just 4 drops morning & evening most days after cleansing and then follow with my usual moisturiser and a drop of facial oil. Highly recommended. 

I had something similar to this ages ago with the skin analyser bulbs on the back, but have misplaced it somewhere since, so I decided to try the luna play smart because I remember it being really good. No surprise, I absolutely love it. It does a great job at cleansing, I like knowing which part of my face needs some extra attention and my skin is looking a lot better again.
