In this post, I wanted to talk about mixing active ingredients in formulations. We want our formulations to do something. This leads to adding multiple actives to approach skin issues from different angles. It can be confusing on what we can add together or not.  Everyone approaches this differently; however, I want to make sure that they are done in a way that makes sense. 

I researched this topic a while ago and it occasionally comes up, but I do want to talk about why I still heat and hold. I have seen multiple argument for it. There are some that are based on science and others on bias.

There has been a ton of buzz with Niacinamide. So, I have been getting a ton of questions about how to formulate with it. The main questions was what pH should we formulate it to as there is a lot of contradicting information. I was going to make a series of formulations; however, I needed to address this first. Let's dive into it.

I have been seeing people add urea into a formula; you cannot do that. This is a more advanced ingredient to work with. It can be dangerous if not properly formulated. I will make this a blog post so you can read the sources. It has been months of research.
