What's your number? <a href=" http://www.catenn.org/desvenlafaxine-cyp2d6.pdf ">pristiq helps</a> The best advice is what we&rsquo;ve known all along: don&rsquo;t smoke, eat healthily, wear sunscreen, but that&rsquo;s kind of boring. Most twentysomethings I spoke to already use anti-ageing creams packed with Retin-A and Renova. There is no doubt that these drugs work, exfoliating, diminishing pigmentation and fine lines, but at what cost? Women&rsquo;s skin is thinner than men&rsquo;s, and these powerful formulations &ldquo;refresh and reveal&rdquo; by stripping off the top layer. Dermatologists warn that such ingredients are too harsh &ndash; they make skin look brighter, but also make it more susceptible to damaging UVA rays. Add in dermabrasion and chemical peels, and it&rsquo;s not a pretty picture.
