Have been using firming serum from Ark for three years and love the product. The new formula is amazing and I can genuinely see and feel a difference in my skin - it's much firmer! My favourite product, wouldn't be without it.

I've been using the Firming Serum with a jade face roller. Great combination to give a lift to the skin. I love this serum because I know it is firming but also adds moisture. Perfect - thank you.

I have been using this product daily for about a month. My face feels more moisturised and I can definitely see an improvement in my skin tone. Great value as a little goes a long way.

Amazing - I love it! Made a noticeable difference to my skin, firmer and a dewy glow. I really like the fact you can use under moisturiser or mix in. Smells good too.

It's too early to say whether I can see the difference, but I love the texture and also the hygienic pump on cream which I mix with serum. Feels good and smells even better. Already a convert!

This serum has made my skin softer and firmer than it has been for years. I just love it and mix a couple of drops with my Age Defy moisturiser, morning and evening, before smoothing it into my skin.

Excellent product - easy to use and problem free - would definitely recommend it and order it again - in fact I have just done that!
