I am also in my 50's and although I wouldn't say I have any problems with my skin,my skin just looked a bit "dull".
I don't rate Elemis or Gatineau at all and think they are hugely expensive for not very special products!
Decleor... I like some of the products...but again the cost doesn't justify the results.
I had been using the Boots Protect & Perfect range and was quite happy but when I saw the last JW TSV I thought I would give it try.
I have been pleasantly suprised by the results,my skin is moisurised ,soft and has more of a glow to it now and the texture of the skin round my eyes has improved.
The packaging is cheap and naff and the lids are poor but the products on the whole suit my skin and my budget.
The Rose serum is especially nice!!
