It is predicted that by 2012, international output value of anti-aging cosmetics containing natural plant ingredients will reach $ 10 to $ 20 billion. It is expected that China will have promising development in this field. In all kinds of anti skin aging cosmetics raw materials, fruit acid (chemical name is alpha hydroxy acid) always has a dominant position. In 1996, the consumption of fruit acid is up to 500 million U.S. dollars in cosmetics industry. In 2012, it will exceed $ 600 million.

If one of them makes people allergic, the entire cosmetics are not suitable for use.
Common allergy cosmetics materials are spices, preservatives and hair dyes. Among them, spices are the most common ingredient to cause the allergy. 30% to 45% of eczema patients with cosmetic allergic reactions are caused by cosmetics spices. However, for the principle of confidentiality, the manufacturers will definitely not to public spices indigents. So the consume can not know whether the cosmetics spice will cause the allergy. They can only take the approach of skin test.
