Series from a question from Patreon: What's a cosmeceutical" What's an active" And how much can we use of these things in combination" Part four - considering a formula
Let's analyze a potential formula here to see if I can include all the ingredients I want. In yesterday's post, we set out a list of things to consider when making something, and I'll review that after we consider all our products...
If I were to make an oil free gel for my rosacea prone skin, what ingredients might work together"
1. Niacinamide and n-acetyl glucosamine: I'm using this combination to help reduce sebum production and increase hydration in my skin by boosting production of hyaluronic acid. I know niacinamide needs a pH around 6, so that limits the other ingredients I could use.
I can't use most forms of Vitamin C as they generally need a more acidic pH, but I might be able to use tetrahexyldecyl ascorbate, which is an oil soluble version, as it doesn't need a specific pH level. I could also use magnesium ascorbyl phosphate as it doesn't need a lower pH.

2. Hydrolyzed protein: I can't use this ingredient in most gels as it'll break down the viscosity, so I can't use this with Sepimax ZEN, Ultrez 20, or Aristoflex AVC, to name a few. (It might work with Siligel, which can also handle pH 2 to 11, so that's an option.) I like this for the film forming properties, but I might be able...
