     One of today's hottest topics among women (and to an extent among men too now) is anti

aging and how to reverse the signs of age. The beauty industry has responded to this by offering

a wide collection of anti aging creams and other anti aging products aimed at all pocketbooks,

ranging from economical to highly priced.

     And the question is "do any of these often much-vaunted (被过度吹嘘的) anti aging creams

actually work?" And if they do,how precisely do they perform their miracles?

Well the appropriate response to that is that they do work - after a fashion. There certainly are

anti aging creams available for a relatively modest price that will reduce the appearance of wrinkles

in a comparatively short period of regular application. But this really is the limit of their powers:

they won't actually undo skin damage or eradicate (根除) all signs of age;they will simply modify

them,some more effectively than others.

     The way they work is like so: they remove upper layers of dead skin cells and make deeper

layers absorb water,serving to plump them up and make them look fuller and healthier. But since

such anti aging creams only go skin deep,as it were,skin damage will reappear once you stop using

the anti aging wrinkle cream.

This means fairly heavy regular use,which might be costly depending on your choice of product.

However,if you can afford it or think it's worth the cost,it won't be such an issue. After all,what

woman wants to look older than her years when looking good is so tied up with many women's

self-esteem and sense of identity.

     A compromise (折中) solution for those on a tighter budget is to use the cheaper creams. In

addition,it's always wise to be a little experimental to make sure you end up with the one that suits

our skin best.

     So,to sum up: an anti wrinkle face cream will work within limits,depending on your objective.
