When i was about 17 I read in a teenage magazine that looking after your skin was far more important than the make up you used.
So since then I have massaged moisteriser gently into my skin every morning, as I have got older i have used more and massaged longer and I think my skin shows the benefit of this, be ing much smoother and less lined than the skin of others my age.
I have always used the cheapest moisteriser I could get away with, Boots own brand and then when I began to develop allergies to some of the chemicals, I moved to organic moisterisers.
I have always taken my make-up with theatrical make-up remover, I used to buy it in big pots from Boots, now I buy it online.
I am not remotely interested in looking young for my age, just being well maintained at any age. In the way that you keep a house or an old car in good order regardless of age.
