La Prairie has been using caviar in her skincare products since 1987, and the caviar range has become a classic. Launched in 2018, Caviar Firming Serum is La Prairie's most recommended lotion. Caviar from sturgeon is recognized as the best quality, its extract is an important ingredient in this lotion, and La Prairie uses an innovative distillation process to obtain more essence ingredients than commonly used extraction methods, so it is also quite expensive, a 150ml bottle of lotion can sell for 2,200 yuan.
 
Caviar Firming Essence, also known as "anti-gravity water", focuses on firming and anti-aging, suitable for mature skin. The liquid obtained after the condensation of steam fumigation caviar pearls has a clear and light texture, comfortable skin feel, high moisturization, suitable for all skin types, with it as a foundation, subsequent skin care will be better absorbed, even in the change of seasons, the skin condition is very online. The packaging of this lotion continues the classic dark blue color of the caviar series, and the elegant fragrance makes people feel happy, but the glass bottle is not lightweight, and the large opening is often criticized, so you need to pour it out carefully when using it to avoid leakage.
 
La Prairie is expensive mainly due to the preciousness of the ingredients themselves, the difficulty of R&D and extraction and the high quality of the manufacturing process, but these precious ingredients are mostly added conceptually, and "water" is the first ingredient in lotion content, and this product design determines that it has a short retention time on the face, a large molecular weight, and a low absorption rate, so do not expect too much from the anti-aging and whitening effects of a bottle of lotion. As the first step in skin care, the basic function of lotion is to hydrate the stratum corneum, make the skin plump and comfortable, and make the follow-up skin care better. However, lady-type skin care products focus on experience, and the best experience is when used with a complete set of skin care products in the caviar series.
