Dr.Sue Mayou,consultant dermatologist at the Cadogan Clinic in London and spokeswoman for the British Skin Foundation, says: I use Tretinoin twice a week. It is very drying so you have to moisturise well.
The rest of the time, I use a not especially expensive moisturiser that contains retinol. RoC Retin-Ox(25.95) is as good as any. Retinol a form of Vitamin A - may also have an anti-ageing effect. Unfortunately it is only about a tenth as effective as Tretinoin so, at best, it may have only a marginal impact. The same may - or may not - hold true for other anti-wrinkle ingredients touted by the cosmetic industry.
It is possible that they do work, says Dr.Mayou. But if the companies prove it categorically, then their products would have to be licensed as medicines . This means it would be available only on prescription which, in marketing terms, would be madness.
