I have dry skin and initially followed the instructions provided - serum, then day cream in the morning; serum plus restorative night cream in the evening. Unfortunately the day cream wasn't moisturising enough. I then decided to use the restorative night cream which was much more hydrating in the morning and evening.
After about 5 days of using this, i developed a rash under my left eye and found my eyes very puffy in the morning. I didn't initially link it to the products but after a few days when the rash and extreme puffiness around my eyes worsened, i decided to stop using the products around my eye area. The puffiness reduced within 2 days however the rash is taking some time to go away.
Final recommendation: whilst my smile line did look more plumped and the restorative night cream was hydrating, I wouldn't recommend it for those with dry or sensitive skin.
