The No7 Laboratories Line Correcting Booster Serum [1] (£38) is finally available after having a wait list of over 17,000 people in the UK and Ireland. The serum is only sold at Boots [2] and was just released on April 11. Why all the hype? It is clinically proven to reduce the appearance of wrinkles [3], and was specifically designed to be applied directly on lines and wrinkles.

The serum can be used as the first step in your morning skincare routine [4] or at night beneath your usual serum or moisturiser. That's not all: it can also be mixed with your moisturiser, foundation, or eye cream to boost age-defying results. The secret ingredient? Matrixyl 3000 plus, a blend of peptides that help promote skin cell turnover and effectively remove facial wrinkles [5]. No7 told POPSUGAR that since the serum's release, one is sold every two seconds.
