At our BeautyPass Live event in New York City back in October, celebs and skin gurus were praising No7 products all night long. Though there are so many noteworthy products in the brand’s lineup, the Line Correcting Booster Serum is undoubtedly a standout. (I’m also a big fan of the Future Renew collection.) If you’re someone concerned with fine lines and wrinkles, consider adding this to your routine. Here’s what sets this peptide-packed serum apart.

The Benefits of This Serum

Powered by Matrixyl 3000+, No7’s proprietary collagen peptide technology, this serum is ideal for anyone with stubborn lines and wrinkles. In fact, it has seven times more Matrixyl 3000 Plus than any other No7 serum. That equates to a lot of line-smoothing power, and I’m not surprised people are obsessed with this product. It also has more than 5,000 positive reviews on Amazon. My forehead lines and 11s are my biggest areas of concern, and this serum is perfect for them. It’s so easy to use, and actually kind of satisfying to squeeze the serum out of the targeted tip, dragging it directly across my lines. It feels like I’m “filling” them in.

In a clinical study, after one week, women saw a visible reduction in the appearance of lines and wrinkles on the forehead and around the eyes (crow’s-feet). By two weeks, they saw visible improvements in four additional targeted wrinkle areas: around the lips, between the brows, under the eyes and the nasolabial folds. In a survey of women who had purchased the serum, “8 out of 10 would choose this product over an expensive clinical treatment.” I love using this treatment in between my Botox appointments to keep my forehead and 11s smooth. I think this is a great product for anyone who isn’t ready for injectables yet, or doesn’t want them, but wants smoother skin.

How to Use It

You can apply the serum on its own directly to lines and wrinkles using the targeted tip. (Twist the base of the applicator to unlock it.) Or, you can use the serum as a booster and mix a couple drops into your moisturizer or eye cream. Apply it morning and evening for optimal results. I also appreciate that the serum layers well with other products, aka no pilling.
