The skin-care internet is full of dubious DIY remedies, but the ones that suggest black tea as an under-eye bag treatment actually hold weight. The caffeine in black tea is considered a “vasoconstrictor,” meaning that it’s capable of temporarily shrinking the size of blood vessels. Studies also indicate that the topical application of caffeine smooths skin, which is why caffeine is often found in cellulite creams. These two factors work in tandem to help your eyes look a lot less puffy.
Retinoids are one of the most well-documented wrinkle fighters around, reversing the signs of aging in study after study (after study). A class of chemicals derived from vitamin A, retinoids work in two ways: First, they help your skin slough off old cells and make new ones — a process our bodies are good at when young, but which slows down as we age. Second, they spur collagen production, improving elasticity and filling in lines — another natural process that tends to slow down with age.
While we like to think we actually get better with age, we totally understand that there might be some pesky skin changes you want to address as the years pass. It's difficult to pinpoint exactly when to start incorporating anti-aging products into your routine, so we chatted with one of our favorite experts, Genevieve Vielbig, R.N., B.S.N., C.A.N.S., to get the scoop on the best approach to wrinkle creams.
• I did not like anything in my box: Our editors work to inform you of and introduce you to the best products each month, and while Allure is the beauty expert, we understand that everyone's beauty routine is different. Some products may be a better fit to some more than others, but that's part of the fun and part of the service our editors provide: helping you learn about new products. We encourage you to share your samples with your friends, and hopefully next month's box will include products you will enjoy! There are some great forums online for sample exchanging, and we hope you reach out to other subscribers to swap for something you'll love.
