To keep others from making exact copies of their Collagen Refresh Lemonade Review products, the cosmetic companies don't have to write out how much of each ingredient a product contains. Still they have to arrange the INCI in order of quantity. So the first ingredients are the ones that you should be most careful about, since the product mainly is composed by them. 

Normally the first 4-8 ingredients are the big ones, while the rest are just included in very small quantities. Even though an ingredient as such might tell you nothing, sometimes part of the word might give you a hint as to what it is. For example, something ending with -cone, is a silicone, that is mostly used in hair products and generally considered something to avoid. If it ends with -ol, it is an alcohol, if something is hydrolized, it is a protein and so on.
