Great serum but so expensive!
I had a large sample of this from a SoaceNK gift, it is an amazingly light serum which sinks into the skin so well without any stickiness and my skin looks great even after only a week of using it. I would love to purchase this in a full size but it’s just so expensive!
Best Use: Hydrating, Minimise Fine Lines & Wrinkles

Almost perfect!
Love the texture, love how it feels on the skin. The only thing I don't love is the price! Because it is so watery and absorbs so fast, you really do doubt if it is doing anything at all or if you are the Emperor with no clothes on. Luckily, I do think that my skin looks better when I regularly use it. If only I could afford to buy it regularly!

Great stuff!
I have had a luxury sample of this and love it. It sinks in quickly and easily. No smell and makes your skin look great. Feels supple and youthful. Someone recently thought 16 years younger. The price tag is prohibitive however which is why I am giving it 4 stars. I might treat myself one day hopefully to a full size!
Best Use: Reduce Dullness, Anti-Aging

Amazing
I received a decent sample of this as part of the Autumn gift with purchase and was absolutely totally impressed with it. The effect on my skin from using this product is amazing. It feels so plump, smooth and hydrated and my wrinkles are definitely less noticeable particularly on my neck. I really love this product.
Best Use: Hydrating, Minimise Fine Lines & Wrinkles, Firming

Wow.
My wow goes to both the product and the price. Yes it’s a lovely serum,I received a sample of this in the beauty discovery gift. Now I’ve seen the price I’m saving it for when my skin needs a treat. I am sure ideally it’s best used consistently but at the price I’m not sure when I would even consider purchasing the full size. Maybe if it was in a bundle it would be an option. Nevertheless It is really lovely to be able to try such high end products.
