Yassan is branded and brand name. Yavan cheol is the brand name of taiwan in guangzhou, china. Its products are mainly cosmetics. Yaspan cheol is a professor of chinese skin diagnostics, and yashu cheol is the only type of biofunctional maintenance product in china that is based solely on the needs of chinese skin physiological characteristics and problems. Each item is tested at the national level with a test report. It is only 0. 02 micrometres in diameter and is so small that it can penetrate every layer of the skin that it releases energy on a layer-by-story basis to care for each layer of cells. Each person's skin is different from the products used, and human metabolisms are relatively strong and water is lost faster, so it's the first thing to refill it. There are a number of products that respond to different skin problems and different needs for skin protection, such as purified bottles suitable for use by people with mosaic skin, large fur holes, dark scabies and puffs; ct moistures suitable for use by people with dryness, aging, laxity, wrinkle skin; and raw luminous lumin for use by people with rough skins, darkness, fatigue, lack of energy. The middle and low-end markets have low consumer-driven operations, low prices, and 70 per cent of cosmetics are not sustainable. There are hundreds of different brands, lack of brand effects and faithful customers. High competition, homogeneity of products, high rent, high hoarding, high competitive pressure. The survival rate is low, and almost 70% of cosmetics stores are in a state of loss or loss. Advocating for proper skin care helps you to stay young and eat less, skin maintenance is like physical maintenance, requires daily nutrition, requires often short periods of professional care, rather than long periods of care, and occasionally eats a "skin food" that makes it easier for skin to be fed and cared for in a timely manner, as well as for overnourishment caused by one-time ultra-long care. Skin is like a cortex, containing gelatinous fibres and elastic fibres, with frequent intense and long massages, which can lead to gradual loss of elasticity and acceleration of ageing。
