February 27, 2009, as the official birthday of the blog as this is when I decided to blog every single day about some kind of bath or body thing, be it an ingredient, a recipe, or a fun fact to know and learn. One of the earlier posts was entitled Humecants are a girl's best friend, and I wrote a little bit about each humectant along with my basic recipe. A few weeks later, I wrote up a post about the chemistry of humectants - Better crafting through chemistry: Humectants. Well, it's time to revisit the topic of humectants with a lot more science and study citing (and fewer assumptions about the gender of my readers!).
The first question I want to pose to you is this...where did you get the idea that adding glycerin to lotion or hair care product could result in glycerin sucking the moisture from your skin or hair? Please provide me with information like "this forum", "this web page", "this book", and so on. If you can't remember, then saying "I can't remember..." isn't a bad thing!
Join me tomorrow as we review some skin biology so we can understand how moisturization actually works! (If you're a keener, click here as this is where we'll be starting!) Then we'll take a look at our hair and moisturization!
I realize this might not look like I'm listening to you with the whole what do you want to know post, but I thought we could use a little review about humectants, how they work, how moisturizing works, how our skin works, how our hair works, and a few other things, while taking a deeper look at humectants, which are huge in the cosmeceutical and hair care products right now! The more you know about these issues, the more power you have to analyze whether an ingredient brings what you want to your facial, body care, or hair care product!
