Sounds like a beauty lover’s dream? Completely. That’s why we asked ELLE Beauty Editor Melissa Perdigao to test-drive Lancôme’s latest e-Youth Finder tool. Here’s what she thought.

“Lately, stress has taken a major toll on my skin. And after a long time spent indoors, my main concern is getting my glow back. As someone with dry skin, I tend to lean toward products that keep my skin hydrated and dewy but also supple and bouncy. I was impressed by how easy the e-Youth Finder tool is to use and how it identified my skin’s most pressing needs. It’s like it read my mind!”

After testing the e-Youth Finder, Melissa tried out Lancôme’s age-defying Génifique serum along with the Hydra Zen Anti-Stress Glow Liquid Moisturizer, and the results are in. Below, she shares her thoughts on the products.

“The tool identified radiance and firmness as my top concerns, so each day I applied the Génifique serum—loaded with skin-balancing prebiotic and probiotic extracts as well as hydrating hyaluronic acid—to plump up my skin and the Hydra Zen to brighten my complexion and protect against external aggressors like pollution and stress. When I paired them together, the results were fabulous. Immediately, my skin was glowing—I felt like it was covered in a veil of protection, and I looked visibly refreshed. This duo has earned a permanent spot on my skincare shelf!”
