In an interview with Glamour, the Crazy Rich Asians star said that if she could only use three products for the rest of her life, the L'Oreal Paris Hyaluronic Acid Serum would be on the top her list. And she's not alone in her obsession with this skin care product — over 22,000 reviewers on Amazon have given this serum five stars.

The serum's popularity stems from its two main powerhouse ingredients — hyaluronic acid and vitamin C. Hyaluronic acid is the ultimate ingredient when it comes to hydrating skin because it attracts water on a molecular level, allowing more moisture into your skin's natural barrier while keeping it there for longer. The immediate result is plumper, more dewy-looking skin, with a reduction in wrinkles after prolonged use. You'll also notice that hyaluronic acid can improve your skin's elasticity, helping it to look firmer overall.

Vitamin C is another a great ingredient when it comes to improving your complexion. It can promote more collagen production in your skin, which further reduces signs of aging like wrinkles and age spots. It can even help repair sun damage.

And reviewers love the results.

"I feel I look five years younger," one happy reviewer said after using the product for a week. "My complexion is incredible. Can't imagine going without this product ever again. Unbelievable product!"

"I'm 50 years old and this product has help with wrinkles," another added. "I have tried everything on the market and this is the best. I have seen a huge difference on my face and neck."

One stunned reviewer even notice a reduction in deep-set wrinkles. "I had deep lines develop around my mouth and decided to give this a try," they said. "It did plump up the lines permanently after a couple of months use.... The surprise, however, came several months after using and I happened to look in my rear view mirror one rare day that I went without makeup and noticed the lines on my forehead were gone! I did not anticipate that it could erase those lines — I thought those results were impossible to accomplish. Now I use it for continued results on my forehead as well as the results around my mouth."
