20s Prevent Aging
"What you do in your 20s is going to impact your skin in the future," says New York City dermatologist Jeannette Graf. "Start using retinol at night to fight aging and minimize pores." We like DDF Retinol Energizing Moisturizer ($85). For daytime, sunscreen and mineral makeup are recommended. "Minerals work well with oily skin, have a natural SPF, and enhance the protective effect of antioxidant enzymes in the skin that help prevent fine lines and uneven tone," advises Graf. Try Shiseido Extra Smooth Sun Protection Cream SPF 36 ($27) and Neutrogena Mineral Sheers Powder Foundation ($12.99).

30s Keep the Glow
Even if you're able to get eight hours of sleep, you may still appear tired. "Undereye issues develop at this age," says makeup artist Brigitte Reiss-Andersen. "Pick a concealer with a warmer tone, which blends better and is less noticeable." To cover up unsightly dark circles and reduce puffiness, try Clinique All About Eyes Concealer ($15.50). Have you noticed that your skin is getting drier? "A lack of hydration affects the natural exfoliation process, causing it to slow down, which can make skin look dull," says Graf. When rubbed against wet skin, Blinc Resurf.a.stic Face stick ($40) exfoliates with diamond-shaped crystals as it hydrates with glycerin and cactus extract. Use it once or twice each week.

40s Get Even
"This is when you see more age spots, sun spots, and discoloration," says Graf. Add alpha hydroxy acids to your routine, and use a mask with algae to increase microcirculation and even out your skin. Try Dermalogica ChromaWhite TRx brightening regimen ($188) and H2O Plus Hydrating Marine Moisture Mask ($25). And if you aren't using a primer, it's time to get started. "Primers moisturize and smooth the skin," says Reiss-Andersen. "If they have a little shimmer, it makes your face brighter." For a flawless base, choose Make Up for Ever HD Microperfecting Primer ($32), available in six shades to correct every skin tone.

50s Soften Wrinkles
You may notice that your wrinkles have become more apparent and your skin is drying out. "The loss of hormones during menopause affects elasticity, firmness, and moisture levels," says Graf. "To resolve these issues, use products at night that increase collagen production." Try Darphin Prédermine Densifying Anti-Wrinkle Cream ($185). "You'll also see lips start to sag and shrink," she adds. Lancôme L'Absolu Rouge lipstick ($29) contains Pro-Xylane to boost moisture and plump out lines.

60+ Maintain Moisture
"Oil production drops dramatically at this age," says Graf. She recommends a cream with DHEA, like Rejuvenex Ultra RejuveNight ($39), which can enhance the moisturizer's effect on your skin. And when you apply makeup, "stay away from powders that can lodge in wrinkles," warns Reiss-Andersen. Try a liquid foundation like L'Oréal Paris Visible Lift Line-Minimizing & Tone-Enhancing Makeup ($14.25), which uses Pro-Retinol A and hyaluronic acid to smooth and hydrate skin.

20岁 防老化

“20岁所作的努力会影响你未来的肌肤”，纽约市皮肤科医生Jeannette Graf说。“晚上开始用松香油收缩毛孔”。我们喜欢DDF松香油能量保温霜（85美元）。白天则建议用防晒霜和矿物化妆品。“矿物质对油性肌肤很好，含有天然SPF防晒成份，增强皮肤里抗氧化剂的保护作用，有助防止细纹和肤色不均”，Graf建议说。尝试资生堂的SPF36防晒霜和露得清矿物隔离底粉（12.99美元）。

30岁 保持光泽

即使你可以保证每天8小时睡眠，你仍然可能看上去很疲惫。“这个年龄开始出现黑眼圈”，化妆师Brigitte Reiss-Andersen说。“选用温和的遮瑕膏，可以混和更好，使黑眼圈不那么明显”。要遮盖难看的黑眼圈减少眼袋，试一下倩碧的全效眼部遮瑕膏（15.5美元）。有注意到自己的肌肤开始变得干燥吗？“缺水影响了自然脱落过程，导致过程减缓，这样使得皮肤看上去暗淡”，Graf说。当按摩滋润的肌肤时，Blinc Resurf.a.stic Face面贴膜通过钻石样的晶体脱落，因为它与甘油和仙人掌提取物水合。可每周使用一至两次。

40岁 保持平衡

“这个年龄段出现老年斑，晒斑和褪色”，Graf说。在日常生活中添加阿尔法羟基酸，并使用海藻面膜以增加微循环抚平肌肤。可试一下德美思嘉ChromaWhite TRx增白剂（188美元）和H2O补水海藻保温面膜（25美元）。如果你还没用底粉，要开始用了。“底粉可滋润光滑肌肤”，Reiss-Andersen说。“如果底光含少量淡光，则可提亮你的脸”。为实现很好的打底，选用Make Up for Ever的HD Microperfecting Primer（32美元），一共有6种色调可用来纠正所有的肤色“。

50岁 软化细纹

你可能注意到你的皱纹越来越明显了，肌肤很干燥。“更年期荷尔蒙的失去影响皮肤的弹性、紧致度和滋润程度”，Graf说。“要解决这些问题，晚上使用能增强胶原产生的产品”。试用Darphin Prédermine Densifying防皱霜。“你还可能嘴唇开始下垂和萎缩”，她补充说。兰蔻的L'Absolu Rouge润唇膏（29美元）含有Pro-Xylane可增加水份，填平细纹。

60岁 保湿

“这个年龄段油份产生显著降低”，Graf说。她建议用含脱氢表雄酮（DHEA）的面霜，如Rejuvenex Ultra RejuveNight晚霜（39美元），可增加肌肤的保湿效果。如果你化妆，“不要用粉底了，粉底会留在皱纹里”，Reiss-Andersen提醒说。试试液体粉底，如欧莱雅的可见提升去皱亮色化妆液（14.25美元），这款产品使用和Pro-Retinol A和透明质酸，使你的肌肤光滑滋润。
