The Best Retinol Formula We Tested for Fine Lines Is on Sale Right Now at Amazon for Under $20

It’s never too late to improve your complexion. And right now one of the best over-the-counter products with retinol the PEOPLE Tested team tried is on sale at Amazon.

The Neutrogena Rapid Wrinkle Repair Retinol Serum is 42 percent off, which brings down the price to just $17. We tested 32 retinol formulas for 12 weeks, evaluating them on how well they combined with other skincare products, and whether they improved skin issues like wrinkles, fine lines, and dark spots — and the Neutrogena Rapid Wrinkle Repair Retinol Serum was deemed the best for fine lines.

The formula includes two main ingredients: retinol and hyaluronic acid. Together, they help diminish fine lines and wrinkles, and brighten the skin. Our testers described the drugstore serum as a “potent elixir,” and they noticed smoother fine lines after using it regularly. The testers also loved that the formula is unscented and gentle enough for daily use, unlike some of the other formulas they tried. And it’s an excellent option for those who are sensitive to fragrances.

Our testers were also impressed with the “fast-absorbing” formula since it made applying other beauty products a breeze. However, they didn’t think the serum changed the texture of their skin or reduced the appearance of dark spots. But they still liked the product overall, stating, “We loved the way the drugstore retinol targeted our fine lines and were, overall, highly impressed by the outcome — especially for the price.” 

Amazon shoppers are also fans of the retinol serum. It has racked up thousands of perfect ratings, and more than 3,000 people have snapped it up this month. “This formula is lightweight and silky smooth,” one user wrote. “I've been using it for about a week and can already tell the difference in the appearance of fine lines.” 

If you're looking for a lightweight formula that will help minimize the appearance of fine lines, head to Amazon now to scoop up the Neutrogena Rapid Wrinkle Repair Retinol Serum for only $17.
