Formulating for dry skin: Moisturizers

How does a moisturizer differ from a lotion? A moisturizer is an emulsified product, like every other lotion, but they tend to have a higher water phase than other lotions. Generally moisturizers are 80% to 90% water, which means we have a 10% to 20% oil phase, which isn’t huge when you consider that we...

Question: Does propylene glycol cause badness to our skin?

In this post, seventh77 asks: I’ve come across various “organic skin care” blog-type sites that claim propylene glycol “denatures” skin and causes it to age prematurely and sag. Is there any truth to that?I answer the question in the comments in the post, but the short answer is no, there’s no truth to these claims. And...

It’s been a painful week!

Thanks for your good thoughts about my math exam! I got an A-, something I didn’t expect as I wrote it while enjoying some serious back and hip flexor pain, a memento of a serious fall I had on a ferry four years ago. I hope to get back to writing more detailed posts on...

No post today – math exam!

I’m doing my final exam for math tonight, so this morning is dedicated to doing last minute revisions to those concepts that have refused to take up residence in my head. I started the class in January, and I can’t remember anything past last week. What’s up with that? I’m stuck on logarithms and exponents...

Formulating for dry skin: More facial cleansers…

I love this creamy exfoliating cleanser! I can use it for my oily skin maybe once a month and my best friend with normal skin can use it once a week, but someone with dry skin could use it every day, although I’d make a version without the jojoba beads because you don’t want to...

Formulating for dry skin: Toners continued…

As we saw in this post and this post, the pH of our skin care products is absolutely vital, and more so for facial products. When we’re creating a cleanser, toner, or any other non-lotiony product, we have to make sure we are testing our pH and ensuring that it will be in the right...

Chemistry of our skin: pH and our skin care products

As we saw yesterday, the pH of our skin is pretty important. Out of whack pH levels can lead to an increase in scaling, a decrease in hydration, and a possible increase in bacterial and yeast infections. In short, having an out of whack pH level can lead to dry skin and icky infections! (And...

Welcome Finland!

I noticed one of the blogs that has linked to my blog is Fashioned in Finland! I don’t know much about Finland except these things… – Monty Python has a great song about your country– I’m really enjoying Nightwish (although I prefer the first singer over the new one)– you produce great hockey players,– your language...

Chemistry of our skin: pH of our skin

I’ve found such an assortment of really interesting papers on the pH of our skin, I had to share them with you! The writing in purple is the text from the study with my comments before and after. What is the proper pH of our skin? As I’ve written in the past, the general range...

Baking Owl comes out of retirement!

When I was a Brownie leader, the girls thought I should be called Baking Owl because I’d be compelled to bake for them! I was eventually called Fluffy Owl – thanks to my poofy hair – but I still baked them things occasionally. Baking Owl is back, and boy, did I create a mess! Eight cake...
