Drew Barrymore is the queen of keeping it real, especially when it comes to her skincare routine! The actress and talk show host has often shared glowing endorsements for her longtime favorite products, especially the Sunday Riley Good Genes All-In-One Lactic Acid Treatment.

“I’ve been using this product one to two times a week at night and love the results!” she shared in an Instagram video. She even called it an instant “amazing polish” for her face.

This serum delivers visible results fast. Barrymore said that after just a couple of uses, she notices “a major difference in the brightening, the tightening and the youthening” of her skin (and honestly, same, Drew). If your complexion’s been feeling dull or uneven, this glow-boosting formula might just be your shortcut to Barrymore-level radiance.

It’s no wonder she calls this serum her “brightening and tightening” secret — it’s basically a facial in a bottle. This cult-favorite formula uses purified grade lactic acid to exfoliate dull skin, clear away dead cells gently and encourage natural collagen production. The result? A smoother, more radiant-looking complexion that practically glows on its own. It’s a multipurpose powerhouse that works fast — and yes, we mean fast.

In clinical studies, 100% of women said their skin looked and felt noticeably smoother, plumper and more radiant after application, with visible improvements to fine lines and wrinkles in just three minutes. That’s right: brighter, more youthful-looking skin before your next Zoom call or night out! No wonder so many shoppers call this their holy grail product for instant glow!

But it’s not just the exfoliating magic that makes Good Genes so beloved. It’s also got a soothing, balancing blend of licorice, lemongrass and aloe. Licorice naturally brightens dark spots and discoloration; lemongrass amps up radiance, and aloe keeps everything calm and refreshed. The formula is gentle enough for most skin types, including sensitive skin, and can even be used as a rinse-off mask if your complexion needs a softer touch.

To use, simply apply one to two pumps to clean, dry skin day or night as a leave-on treatment. Or, those with sensitive skin can leave it on for 15 minutes and then rinse for a milder glow boost.
