The best skin product ever
I was told about this product by a beautician and it's been a revelation. My skin is much softer and I need hardly any moisturiser after 4 months of use. I've recommended it to my sister and son, who both suffer from very dry skin on their face and they saw an immediate improvement. I use 4 drops every morning and use Medik8 Retinol 3TR every other evening. I love it!

Healthy skin
This was recommended to me by my beautician. I tried it after using the much hyped (an expensive!) Clarins Super Serum. I have found that this serum has given my skin a healthier glow, does not leave it greasy and has cleared up my combination patches. I use it twice a day before day and night creams. Definitely worth the price and competes with the other big players on the market.

Prodotto ottimo, non unge e la mia pelle lo assorbe in maniera ottimale, ormai un anno che lo uso tutti i giorni. Una boccetta ha una durata di 6 mesi circa, rimanendo nell’utilizzo quotidiano di 3 gocce sul viso
