Our 51-year-old beauty expert tests hundreds of anti-aging products: Here are this week's best deals

We're getting deep into the what I consider to be the most perfect time of year, weather-wise, the season Tony Soprano once famously referred to as "effing autumn." And you know what that means: crisp temperatures, bright foliage, the cozy scent of woodsmoke and, among the only downsides, dry, flaky skin. As a beauty editor who tests anti-aging skin care for a living, I'm constantly shifting my focus to meet seasonal needs. And right now I've got my eye on ultra-hydrating products to help soothe cold-weather skin, particularly those that work well for aging faces and necks. I spend hours each week scouring the internet for the cleansers, serums and creams I know help firm, brighten and add moisture — ideally those I can snag on sale.

On any given day on Amazon, you'll find literally thousands of deals on name-brand (and very much NOT name-brand) beauty products. However, not all skin care is created equal. Here is how a product meets my criteria: It must be a formulation I trust, made with high-quality ingredients I recognize and a proven track record of results. The Amazon skin care deals below represent some of my all-time favorite products: Most are clinically proven or, at the very least, wildly well-reviewed.

If you have Amazon Prime, you’ll get free shipping, of course. Not yet a member? No problem. You can sign up for your free 30-day trial here. (And by the way, those without Prime still get free shipping on orders of $35 or more.)
