The Science Behind Beauty: How to Make a Kick Ass Scrub

Hey guys!
So it has been forever since I've done my last "Science Behind Beauty" post, and I've been missing it! I've decided to do one today on how to make a kick ass scrub because it's 1) really simple and 2) really fun! Here we go!

How to make it:
Find your abrasive. The simplest are sugar or salt, but you can choose whatever you want!
Then find your base or liquid. This needs to be an oil (I'll explain later). My favorites are coconut oil, olive oil, or sesame oil. Remember that you're going to have a faint scent of whatever you choose, so choose an oil you like the scent of! 
There are also additives that you can choose to add if you like! Herbs or aromatics make the scrub smell really good. You could also add in essential oils if you want and I've heard of people adding citrus juices as sort of an astringent. 
You can choose the ratio of each that you like, but I tend to eyeball it and put in a lot of abrasive per liquid.
So there you go! That's your kick ass scrub. 

Why it works: 
Salt is an ionic compound, right? It's Na (sodium) and Cl (chloride). This allows it to dissolve in water because the Na is positively charged and the Cl is negatively charged. In oil, however, it doesn't dissolve because lipids aren't charged. This allows you to have the abrasive feeling in your scrub instead of just applying salt water to your skin, which does absolutely nothing. The oil is also really great because it is a moisturizing compound. Our skin cells have a phospholipid bilayer and topical oils help to enhance our natural skin barrier. For best results, use this out of the stream of the water. This prevents the salt or sugar from prematurely dissolving. 

Other notes:
If you're going to keep this scrub to use another day, I strongly suggest using salt as your abrasive because ants aren't attracted to salt and it won't get as icky. Also, if you want to know how I use it, I apply this first, then shave, then apply it again and shave again. The first time I apply it is to remove dead skin cells and when you shave you're removing a bit of hair and mostly the skin cells and when you do it again, you're shaving your hair. Also, be careful if you're using coconut oil because it has a tendency to stay solid at cooler temperatures so it might impact your pipes and stuff (but I wouldn't know because coconut oil is liquid year round in Hawaii). 

I'm so happy that I'm restarting this series! I've missed it so much! Let me know what you think of this post in the comments below and don't forget to follow this blog for more posts!


  1. I was never good at science back in high school, but you made it easy to understand haha. I will have to do some experimenting, I think. Thanks girl! :)

  2. Haha I love science! and I'm super happy that you like this post and it's helpful for you!
