'Can this cream really get rid of my wrinkles? Can it really alter my DNA? Can it get rid of my acne?'
All of these questions require an understanding of how a molecule can reach its target skin layer. Read More
As a cosmetic chemist, it goes without saying that you should have a grasp on skin biology. Aside from knowing the layers of the skin and function of each layer, you have to have a grasp on some other concepts such as:
- How ingredients penetrate the skin
- What type of ingredients penetrate the skin
- How skin actives work
- Which layers of the skin can you claim your product works on
- Validity of consumer toxicology concerns
Over time we will answer these questions in the blog and in my spring e-course. Today we're going to have an overview of the different layers of the skin so you have a general foundation to build upon when you try to understand the concepts above. Read More
Welcome to the last day of this blog post series! I hope you've enjoyed it so far, and have found it enlightening. Today we will cover our last set of molecules--sterols, sulfonic acids, sulfosuccinates, sulfuric acid esters/organosulfates, triglycerides and thio compounds Read More
Day four of my blog post series: Molecules in Cosmetics. Today we'll go over the structures of polyethylene glycol, polyols, quaternary ammonium compounds, sarcosinates, siloxane and soap! Read More
Yesterday we took a look at some of the most important chemical structures you should know about in cosmetic chemistry. Today we'll take a look at halogen compounds, hydrocarbons, imidazolines, inorganic acids, isethionates, ketones, and phenol. Read More
