I can't answer what I'm allergic to. all kinds of lipstick There are many components in the formula. Why do members think that it is caused by the color powder in lipstick? and then losing but use a different lip color No allergic reaction or not? If it's another color that has been used, there is no allergy. is the same brand Or each brand?

My friend is allergic to artificial colors and น้ำหอม in lipstick, so I want to know what colors are mixed in. In lipsticks such as Iron Oxide is it considered Aritificial color?

Please ask for more definitions of organic chemical colors. Thank you

Hello,

would like to know what color is mixed in lipstick, for example Iron Oxide Is it considered Aritificial color or not?

I don't know because the word Artificial color that members have notified. The team doesn't know who this definition is. Members must try to ask the meaning of Artificial color from the person who defined this word up. The team will provide information about the origin of Iron Oxide Iron Oxides is caused by Iron + Oxygen found naturally, such as "iron rust" is considered to be Oxidize of Iron, thus causing the rust color. come the source of Iron Oxides used in cosmetics is caused by the use of Iron to react with Oxygen under control. To get the desired color, organic chemistry in Thailand is called "organic chemistry". Learn more here https://en.wikipedia.org/wiki/Organic_chemistry
