La Prairie’s Skin Caviar line is a favorite among skincare enthusiasts — and with good reason. The lotions, creams, serums and oils use caviar extract to plump and firm the skin. Now, 35 years after the line’s debut, La Prairie has launched its newest serum and most luxurious product in the collection: Skin Caviar Harmony L’Extrait Serum. What’s different about it? Well, it promises to diminish vertical lines on the face, so let’s just say I’m in.
Skin Caviar Harmony L’Extrait Serum premiered at Art Basel 2022 in Basel, Switzerland alongside a digital exhibition featuring five emerging artists. Here the luxurious packaging is celebrated with its curves in the cobalt blue glass. But for me it’s all about the good in it, the powerful face serum. Because La Prairie believes that it has found the “key to the harmony of youth” with its latest technology.

La Prairie.
Most antiaging serums target horizontal lines, like the lines on your forehead. This serum goes for vertical lines by strengthening and firming the skin bands in your face. When I tried Skin Caviar Harmony for a little over a week, I specifically focused the serum on my laugh lines and fine lines between my brows, and really massaged it into areas where vertical lines are most dramatic.
Simply applying this serum is luxurious. The tiny microspheres dissolve when rubbed in and the formula absorbs quickly into the skin. It immediately feels light and moisturizing – not greasy and clogs pores (my biggest fear). The brand recommends layering it with Skin Caviar Luxe Cream ($555 at Nordstrom), but since I’m PMS I’ve opted for an oil-free moisturizer to keep my hormonal breakout at bay. (FWIW, it was Reneé Rouleau Skin Recovery Lotion.)
I’m lucky my lines aren’t particularly deep (thanks mom) but my skin does get dry and dull easily which in turn makes even fine lines more noticeable. I can’t promise anything about how strong my skin bands are, but I quickly noticed that my skin looked more hydrated and plumped up in just a week. Skin Caviar Harmony L’Extrait Serum is an investment, but if you’re looking for a luxurious new skincare product, it will make a wonderful addition to your routine.
