The gold-standard anti-aging ingredient retinol, which stimulates cell turnover to boost collagen, is the powerhouse in this serum, dispensed as a special foam for faster absorption. "This faded the dark spots on my cheeks and plumped both my fine and my deep lines," a tester said. "I got compliments on how even-toned and bright my skin was," another glowed. After four weeks of use, 76% of testers saw diminished lines and wrinkles, and we measured a nearly 10% reduction in UV spots in the Lab test, with little to no irritation.
Luckily, there are a slew of skincare products on the market right now that work to fight the peskiest of under-eye bags—no matter their cause. According to Shereene Idriss, M.D., of Union Square Laser Dermatology in New York, anyone looking to de-puff swollen eyes should opt for creams and treatments that contain caffeine, green tea extract, or antioxidants like vitamin C for the best (and fastest) results. "These ingredients work to constrict the superficial vasculature, which results in less swelling," she says.
The only way to ensure 100 percent if the benefits of a particular wrinkle cream are real is to try the product yourself, but a good way to learn more about the various benefits your chosen skin cream promises is to read user reviews. User reviews are easy to find online, and they list the pros, cons, and results of each product, allowing you to make a more informed decision.

In addition to a lack of results, users of prescription retinoids often experience adverse side effects.  Burning and stinging of the skin, redness, peeling, and severe dryness are common complaints. Although many of these symptoms may resolve over weeks to months of use, some individuals experience persistent irritation and inflammation from topical retinoids.
