In addition to the slightly more expensive AQ series, DECORTÉ also has a complete range of relatively affordable series such as Vital-Science, The White-Science, and Micro-Performance. Among its various series of serums, Moisture Liposome moisturizing essence has the best reputation, it has won the top three of the Japanese COSME Awards for six times, and was rated as a palace-level serum in 2009, because the purple bottle is called "Little Purple Bottle", it can be said that it is a model serum with zero negative reviews.
 
The small purple bottle has a good moisturizing effect, which can relieve the problem of peeling, and at the same time make the makeup more compliant. The main moisturizing effect of the small purple bottle comes from a variety of moisturizers such as butylene glycol, glycerin, hydrogenated lecithin, sodium hyaluronate and sodium PCA. Among them, the hydrogenated lecithin has strong permeability and hydrophilicity, which can improve dryness and increase skin elasticity by reducing skin flakes and restoring suppleness. In addition, plant extracts such as birch bark and hops are added to the essence, and most of them are soothing and anti-inflammatory. However, fragrances, preservatives, extracts and chemical sunscreens are all included, and the safety of the essence is not very high, so users with sensitive skin are advised to try it in advance.
 
The essence is translucent, gel-like and spreadable, and can be applied to the entire face in just a few drops, and the fragrance is fresh, light and refreshing. The small purple bottle not only has a significant moisturizing effect on dry skin, but also is quite suitable for oily skin, and the skin feeling is not sticky.
 
DECORTÉ has also launched a rejuvenating essence milk, which has the same effect as the small purple bottle. The core effect of the two is moisturizing, but they cannot meet the needs of mature skin such as delaying aging, so their main users are mostly young women with dry skin. For mature skin, it is more suitable for scar serum, which focuses on reducing wrinkles in addition to basic moisturizing. Moisturizing is helpful for improving dry lines caused by dry skin, i.e. pseudowrinkles, and also has a preventive effect on the appearance of wrinkles.
