The Best New Beauty Products in September, From OLAPLEX’s First Hairspray to MAKE UP FOR EVER’s First Lip Balm

Part of a new three-step system from La Prairie is this barrier-repair serum (there’s also an essence and a cream) built around Hypower LP52, a proprietary complex developed with leading scientists at two Swiss universities, alongside encapsulated glacial minerals that are released gradually into skin. Designed for stressed skin showing signs of fatigue, the serum, which took six years to perfect, claims measurable results across six markers: fine lines, pores, texture, tone, radiance and redness, with barrier function fully restored by eight weeks. It’s suitable for all skin types, even sensitive, and each bottle’s crackled glass finish is designed to be one of a kind.

“We worked with the universities to patent a specific extraction process to get the essential nutrients we needed to create our proprietary complex called Hypower LP52,” says Julien Goetz, a life science expert for La Prairie who is part of the R&D team. “We also created a new cellular model that was able to replicate modern fatigue at the cellular level. In our study, we deprived skin cells from oxygen and then studied how they were able to survive in this particular extreme environment with our active ingredients. We managed to prove that the older essential repair pathways were reawakened, and we are so excited about these results.”
