I definitely recall several properly qualified and 'known' UK dermatologists stating on a 'proper old BBC documentary' scientifically analysing no end of different face moisturiser creams and only rating ONE of them. The Boots No 7 range with the 'overnight' serum containing retinol and nowt else in it known or likely to cause ANY irritation.
I was skint at the time and didn't therefore buy any - but I have been very tempted several times since.
(Terribly dry, itching skin (all over me) and exceedingly brittle finger nails. Recently found to have increased leucosytes in blood, so got to be retested for that in a few weeks .... )
