In 1982, Mrs. Estée Lauder created the first generation of the Petite Brown Bottle, which has remained the core product for decades, and has now developed into the sixth generation of the Tiny Brown Bottle (ANR), which is a milestone product for Estée Lauder. Since its launch, ANR has become one of Estée Lauder's best-selling products.
 
The full name of the little brown bottle is the Essence of Moisturizing Skin, which comes from moisturizers such as polyethylene glycol-75 and butylene glycol, and the core ingredient to achieve the repair effect is bifida yeast ferment product lysate, which is claimed to improve the speed of skin repair, that is, speed up skin renewal. In addition, the small brown bottle is added with anti-inflammatory ingredients such as bisabolol and chamomile flower oil, which can make the skin condition more stable. The moisturizers in the serum make the skin feel more moisturized and moisturizing, which is suitable for users with dry skin.
 
The pH value of the small brown bottle is between 6-7, and it does not contain other irritating ingredients such as fragrance, which is relatively mild and suitable for sensitive skin. The texture of the essence is relatively viscous, the moisture is moderate, the ductility is acceptable, and it is slightly sticky when used in summer. If added to a heavier cream or foundation, it can increase the spreadability and hydration of the mixture. The appearance design of the small brown bottle is simple, with dark brown bottle packaging, with a certain degree of shading, rubber head dropper design, and hygienic use. The fly in the ointment is that when the essence is about to run out, the dropper cannot absorb the remaining liquid, and it is difficult to pour it out completely, which is slightly wasteful. The price of a small brown bottle of 30 ml is 590 yuan.
 
More than 20 years after the introduction of the Little Brown Bottle, Lancôme launched the Little Black Bottle, which also uses bifida yeast fermentation product lysate as the core ingredient, and both are basic skin care serums, and the two have been compared by others. The main benefits of the two products are similar, but there are slight differences in texture and suitable skin type. The small brown bottle has more moisturizing and soothing anti-inflammatory ingredients, and does not add the irritating ingredients of alcohol, which is milder and less allergenic, suitable for most skin types, but the essence texture is sticky and oily skin is not suitable. The little black bottle is infused with alcohol and exfoliating ingredients, and the lightweight texture feels refreshing even in summer, and is popular with users with oily skin and combination oily skin.
 
The reputation of Estee Lauder's other essences is not as good as that of the small brown bottle. The Miracle Plumping Anti-Wrinkle Serum is added with silicone oil, which makes it feel very slippery after being applied to the face, and it is accompanied by mud rubbing, which makes the skin feel poor. The Crystal Clear Whitening Spot Serum also has a certain amount of mud rubbing, and many users report that their skin is getting drier and drier after use, and the evaluation is low.
