Expired Date: 04/2024 Production Date: 04/2021 What it is: An indulgent line-smoothing facial oil imbued with La Prairie's newest caviar incarnation, caviar retinol. The Product La Prairie's Skin Caviar Nighttime Oil ($530) is part of the brand's indulgent Skin Caviar collection. Along with a face serum, eye serum, and eye cream, the Nighttime Oil seeks to lift and firm skin with its namesake Swiss caviar incarnation, caviar retinol. Housed in a gorgeous cobalt blue jar (fun fact: this signature color was inspired by legendary artist and sculptor Niki de Saint Phalle), the silky, oil formula glides onto the skin via dropper, so you won't waste a single trickle. The Formula With the brand's latest launch, the scientists at La Prairie harnassed the naturally-occurring retinol in, you guessed it, caviar. The brand's caviar extraction process maintains both retinol and lipids found in caviar, creating an ideal combination of hydrating and active ingredients. The result? A nighttime oil designed to work with the skin's natural circadian rhythms, moisturizing and firming your skin through the night. Like all retinol, it counteracts fine lines, boosts your skin's natural regeneration process, increases cell turnover, and regulates oil production. But, the magic of La Prairie's caviar formulation is the addition of caviar lipids. The oily composition creates an outer barrier to minimize water loss. And, here's the kicker, this unique blend also helps prevent irritation. How To Use It As with all skincare routines, your nighttime ritual should start with a clean, dry face. The brand recommends you apply all your other nighttime products before finishing your day with the Skin Caviar Face Oil. Simply dispense two to four drops to the palm of your hand and warm the formula between your fingers. Then, apply the oil between your eyebrows, up to the forehead, towards the temples, across the cheekbones and the tip of the nose, and continue down to the jawline. Finish with the corners of the mouth, jawline, and chin. Repeat this pattern until the formula has fully absorbed.
