I am 55 and still have normal skin it seems. I sat for one of those hand held things that tell you how your skin is doing.
I love Elemis Pro Collagen Marine Cream which is a sort of light cream/gel texture based on a seaweed. I use the night version as well, usually buy from QVC when they have TSV kits. I developed mild roseaca so a lot brands I used to use I no longer can. I love Argan oil but buy the non branded version you can get 100mls for around £13 on ebay. Though at the moment I am using NUDE ProGenius Oil at night. I got a sample in SpaceNK and loved it. Then since I had a £10 on my Indulge card decided to buy it. At the moment I am using REN Calming serum during the day under my moisturiser.
Neck cream wise I use Marks and Spencer Age Replenish which totally brilliant and only £12.
