Lancôme's classic Little Black Bottle, which incorporates 9 skin-beautifying patents, is not only a milestone product for Lancôme, but also known as "the future benchmark of the global beauty industry". Launched in 2009, the second generation was updated four years later to the second generation, which contains 40% more active ingredients than the first generation. The 2017 upgrade of the small black bottle has increased the concentration of yeast extract. In just six years since its launch, Little Black has become one of the best-selling skincare products in the world, topped the 2010 Marie de Marie International Beauty Awards, and won 130 beauty awards, including Voce's Best Essence and ELLE Beauty Star.
 
In 2009, Lancôme first proposed the concept of "skin serum", which is a product that promotes the absorption of active ingredients into the skin, and is generally used before the serum after lotion. The lysate of bifida yeast fermentation product is the core component of the small black bottle, which has nothing to do with yeast, but is actually obtained by bifidobacterium culture, inactivation and decomposition of metabolites, cytoplasmic fragments, cell wall components and polysaccharide complexes. The substance is claimed to speed up skin renewal and leave skin looking supple and smooth. In addition, the small black bottle also adds denatured ethanol, which has a certain astringent effect, and the volatility of ethanol also makes the essence feel more refreshing, so it is more suitable for oily skin. Hydroxyethylpiperazine ethanesulfonic acid regulates the pH value, reduces skin irritation from the serum, and softens keratin. Overall, the Little Black Bottle does not target a specific skin concern, but rather acts as a basic skincare basis, allowing users to layer other functional serums as needed.
 
The little black bottle has an egg white texture and a light fragrance, excellent spreadability on the face, and the skin feels silky and refreshing, even if it is oily skin, it does not feel sticky. The degree of moisturization is limited, and other moisturizing products are still needed in the dry season. For those with dry skin, a small amount of serum can also be mixed into the liquid foundation to make makeup more conformable and reduce caking. The small black bottle has a gradient form of partial conical black glass bottle, which has a low-profile and streamlined appearance, and the push-on dropper design allows for precise dosage control. At present, the price of this serum 30ml is about 760 yuan.
 
In addition, Lancôme has also launched an ampoule (skin repair and soothing serum) to be used with the little black bottle. The core ingredient of the ampoule is the same as that of the small black bottle, with a similar texture, and the addition of the anti-inflammatory antioxidant ferulic acid, while reducing the amount of denatured ethanol added, which is less irritating to the skin, and focuses on soothing and improving redness. Comparatively, the little black bottle is suitable for basic daily skincare, while the ampoule is more targeted when the skin condition is unstable.
 
The Sculpting Firming Brightening Serum uses yeast extract as the main ingredient, and adds ethyl VC, Bosonine Pro-Xylane and other substances to achieve the effect of lightening lines and whitening. Absolue Essence contains rose essence, which focuses on soothing and moisturizing effects, including night oils, eye serums and more. Black Gold Pet Essence Milk is a high-end product of Lancôme, which needs to be used with an introduction stick, focusing on firming and brightening effects, suitable for mature skin users, and the price of 30ml is 4300 yuan.
