Sulwhasoo emphasizes the use of herbal extracts, adding a variety of plant extracts to its skincare products. Because the concept of herbal skin care is easily accepted by Chinese users, Sulwhasoo is quite popular among Chinese people. The moisturizing essence is Sulwhasoo's word-of-mouth work, and it has been among the best-selling items all year round.
 
Like other Sulwhasoo products, the Moisturizing Essence also contains a variety of botanical ingredients, among which the Nourishing Extract Complex is its patented ingredient, which is composed of five plant extracts: lily, polygonatum japonica, lotus, peony and rehmannia rehmannia, which mainly play a moisturizing and anti-inflammatory role. In addition, extracts such as licorice root, wheat root, jujube fruit, etc., with butylene glycol, glycerin and other moisturizers, strengthen the moisturizing and soothing effect. At the same time, the essence contains astringent and oil-controlling ingredients such as alcohol and citric acid. Overall, the Moisturizing Serum focuses on basic skin care benefits such as moisturizing and soothing and anti-inflammatory, and is quite friendly to oily skin and acne-prone skin. In addition to alcohol, the serum also contains a certain amount of fragrance and preservatives, which is moderately safe, and sensitive skin needs to be skin tested.
 
The essence is an amber, watery liquid with a medicinal smell, good ductility, and not too sticky, even if it is oily and mixed skin, it is relatively refreshing. For dry skin, the moisturizing effect of the moisturizing serum is limited, but after cleansing, it can be applied more comfortably. The price of 50ml of moisturizing essence is 600 yuan, which is cost-effective.
 
Sulwhasoo's essence is extensive, all of which are based on different herbal extracts as the core ingredients, covering a variety of benefits. In 2018, Sulwhasoo launched Snow Royal Revitalizing Essence Essence, known as an antioxidant and anti-glycation serum, mainly for mature users. Plum Blossom Extract, Papaya Fruit, Red Pine Seed and other extracts are the core ingredients of Snow Royal Essence, the former moisturizing the skin, the latter focusing on the effect of lightening fine lines, and the combination of niacinamide to brighten the complexion. The pale pink ceramic bottle has a high appearance and attracts many female users. The Ginseng Essence contains ginseng essence particles, which are mainly aimed at skin laxity, aging and other problems. The Crystal Snow Brightening Serum has both firming and whitening effects.
