Good advice in these posts.
Most moisturizers work in the same way, by leaving a thin layer of oil on the skin's surface making it feel and appear more supple and moist. Just because a cosmetic product is more expensive doesn't mean it's more likely to work, or prevent ageing. The ones mentioned already are as good as any.
It's important to remember the best ways to avoid premature ageing of skin are not smoking, and protecting from the sun's UV rays.
The skin also reflects general health and changes can indicate disease elsewhere. So if there is persisting dryness not responding to simple moisturizers / adequate fluid intake, especially with discolouration / swelling, it can mean a whole range of other conditions such as heart disease / failure, diabetes, thyroid problems, drug side-effect, kidney or liver disease. Localised crusty or scaly areas, or ulcers, can mean cancer - either early ( precancerous ) or established - needing excision. This is NOT to alarm members - 95 % of dry skins respond to simple moisturizers
