This Drugstore Face Serum Measurably Firmed Skin in Lab Testing

We updated this article in January 2023 to add more information about each featured product, expert commentary and six new product picks based on extensive testing done by the Good Housekeeping Institute Beauty Lab and dermatologist recommendations.

Face serums are the powerhouses of any skincare routine. "Serums are intended to help skincare ingredients absorb more swiftly and deeply into skin," says Hope Mitchell, M.D., dermatologist and founder and CEO of Mitchell Dermatology in Ohio. "They penetrate the skin's surface up to 10 layers deep, addressing damage, whereas moisturizers work on the surface layer, aiding in hydration and creating a barrier against external stressors."

It's true that "serums can be transformative to your skin," adds Zenovia Gabriel, M.D., a dermatologist and founder of Dr. Zenovia Skincare in Newport Beach, California, "but it's key to find a formula with truly active ingredients that are formulated correctly, not just fancy packaging."

That's why GH Beauty Lab scientists regularly test face serums: to identify the most effective formulas, including anti-aging face serums, brightening vitamin C serums, hydrating hyaluronic acid serums and more. Lab experts evaluate them using technical instruments to measure changes in skin (such as wrinkles, dark spots and pores) after use. They are also distributed to consumer testers for their feedback on factors like ease of use, cosmetic properties and effects on skin. Then, thousands of data points are collated to find the top performing face serums. These are the best face serums to get glowing skin at any age, from beginners in the 20s and 30s to over 50 and 60, according to the GH Beauty Lab.
