保存你的钱，跳过这些昂贵的美容用品。 Dermatologists say alternatives give you better value (and glowing skin).
你拼了你的钱，而且你很难值得的产品，工作让你的皮肤和头发看起来很棒。 But, alas, that’s not always what you get. We discovered nine that don’t live up to their promises (and often high price tag), and got the scoop on what to use instead for beautiful results.
恭彩金，医学博士，在加州圣莫尼卡的皮肤科医生说，清洁剂只在你的皮肤的时间很短，所以他们很少有多大的“行动”超越卸妆油，和污垢，任何东西洗面奶应该做的。 A more worthwhile investment: a Clarisonic cleansing brush. Unlike other cheaper cleansing devices, which use manually rotating brushheads that can be too abrasive on sensitive skin, Clarisonic employs ultrasonic vibration to gently, yet deeply cleanse skin. The payoff: Besides减少痤疮的爆发，你会从你使用后的产品获得更多的一拳。
蛇毒和干细胞听起来性感，甚至还可能有一些皮肤的好处。 But nothing has the proven scientific track record of retinoids and alpha-hydroxy acids (AHAs), says Dr. Kim. Both can gradually build collagen, minimize the appearance of fine lines and unwanted pigmentation, and keep pores clear to帮助减轻痤疮。 “These, combined with sunscreen, are the simple foundation of most皮肤科医生的个人护肤方案，”金博士说。
最好的防晒品，你就会使用。 So if you’re more likely to apply a $35 sunscreen because you love the way it feels or smells, slather away. Just be aware that there’s no need to shell out big bucks to effectively shield your skin from the sun. “Expensive packaging doesn’t mean more protection,” says Mona Gohara, MD, associate clinical professor of dermatology at Yale School of Medicine. In fact, Consumer Reports testing consistently shows that many drugstore and mass retailer brands provide excellent protection. P.S.
如果泳装季节的到来，你驶向美丽过道的奇迹药水部分，专家们恳求您节省钱。 “Cellulite is a complex biologic process that no cream can currently correct,” says Mount Kisco, New York-based dermatologist David Bank, MD, who evaluates claims for these products for the Federal Trade Commission. At most, he reports, some creams may temporarily smooth the appearance of cellulite by hydrating the skin or—in the case of那些含有咖啡因的-by略微改善呆滞淋巴系统，这是脂肪团的根源之一的引流。 A more surefire way to disguise the dimpling is with self-tanner; according to Dr. Bank, the darker colour diminishes the “shadowing” created by the alternating high and low areas of skin.
跳过他们，建议乡原博士。 “If they really worked, stretch marks wouldn’t exist!” The one exception is prescription retinoids, which studies show can improve the appearance of new stretch marks after six months of daily use. (Note: For亚慱电竞欧冠竞足-亚博捕鱼电玩黑平台健康原因，类视色素，不能使用在怀孕期间或哺乳。）有关详细显著改善（在一个更为显著的成本），问你关于激光治疗皮肤科医生。 Some lasers can stimulate collagen growth and zap away the redness of fresh stretch marks, while others can re-pigment older marks that have turned white. If camouflaging them is more your style, a little body makeup can help even out your skin.
许多制造商都诚实，他们可以为你的毛孔，这是做什么，暂时减少它们的外观，通常通过与有机硅产品填充。 But some go overboard and承诺实际缩小他们的规模。 Don’t buy it, advises Dr. Kim. “The size of your pores is determined by genetics, and nothing can permanently change that.” What about when pores become enlarged due to acne or sun damage? Since boosting cell turnover can help unclog pores, you’ll get the most benefit from retinoids or AHAs. But manage your expectations. “They can theoretically decrease pore size, just not back to the day were born,” says Dr. Gohara.
“有这些产品中所采用的技术没有根本性的一面，将让他们比药店品牌，”化妆品化学家兰迪·舒莱尔，的创始人美丽头脑网站和头发和皮肤护理R＆d为阿尔贝托卡尔弗的前高级主管。 While any brand—salon or drugstore—will use a proprietary ingredient from time to time, he notes that they both use the same basic ingredients. Be skeptical when stylists advise you about what products to use as well. “They learn about products from the marketing department of salon brands and also make a commission on products you buy from them,” says Schueller. “When they bash drugstore brands, they do so without any real evidence to back up their claims.”
如果你（错误地）相信SPF 100块双倍的紫外线的SPF 50，你并不孤单。 “One of the biggest misconceptions about sunscreens is that those with higher SPFs block twice or triple the rays as lower ones, when they really only provide slightly more protection,” says Dr. Gohara. The reality: SPF 15 blocks 93 per cent, SPF 30 blocks 95 per cent, SPF 50 blocks 97 per cent, and SPF 100 blocks 99 per cent. Despite these incremental differences, research shows people who use higher SPFs tend to stay in the sun longer without reapplying, as well as forgo other sun-protective measures. “They provide a false sense of security,” explains Dr. Gohara.
一个更安全的赌注比天高的SPF值：广谱防晒霜至少30的SPF（作为奖励，你可以省下几块钱，因为较高的SPF往往带有更高的价格标签）。 Then be sure to use it correctly. To receive the promised SPF, you need to apply a full ounce (that’s a golfball-sized amount) all over你的身体。 Reapplication is also a must, so remember to slather on more sunscreen every two hours or after swimming, perspiring heavily, or towelling off.
要删除一个纹身或删除皮赘没有看医生？ Yep, there’s a product for that. But experts caution that these DIY offerings don’t live up to their claims. They include OTC lasers and creams to take the ink out of skin (the best they’ll do is fade the tattoo slightly, says Schueller, who advises saving up for laser treatments instead) and liquid nitrogen solutions that mimic the freezing effect of cryotherapy, a treatment derms use to get rid of skin tags. “It’s just not as reliable as the in-office procedure, and since it has the potential to harm your skin if used incorrectly, it’s best to use it在你医生的指导下，”乡原博士说。
