Maybe the reason for the differences I've experienced is that I used a moisturiser with a chemical sunscreen around my eyes which caused irritation and the spf eye cream had mainly mineral or physical sunscreen.
In the post I've listed the sunscreen ingredient, whether it is chemical or mineral and which type of rays that ingredient protects against. I hope this helps people decide which, if any, product, is right for them.
I've put the ingredients that have an 'anti-ageing' effect in the post. As I said I think a 'Cinderella effect' plays a large part and a lot of people are happy just with that. I only say that something is effective if I can personally vouch it or have seen the clinical data and if not I say the 'brand claim'.
