Calculating Proportions for Skin Peeling Serum
Question
I am formulating a skin peeling serum. I plan to use the following ingredients:
- FruitPeel
- Willow Bark Extract (Natural Salicylic Acid)
- Yeast Resurface
How should I calculate the appropriate proportions (percentages) for each of these ingredients when formulating the serum?
Answer
Subject: Calculating Proportions for Skin Peeling Serum
Regarding your question about calculating the proportions when combining FruitPeel, Willow Bark Extract (Natural Salicylic Acid), and Yeast Resurface in a skin peeling serum:
Since the staff mentioned that these specific ingredients are not irritating and can be used up to their maximum recommended percentages (FruitPeel 3%, Willow Bark Extract 5%, Yeast Resurface 3%), you can formulate your serum by deciding on the desired percentage for each ingredient, ensuring you do not exceed its maximum recommended rate.
The total percentage of these active ingredients in your serum will be the sum of the percentages you choose for each. For example, if you decide to use the maximum recommended amount for all three:
- FruitPeel: 3%
- Willow Bark Extract: 5%
- Yeast Resurface: 3%
Total active ingredients = 3% + 5% + 3% = 11%
The remaining percentage (100% - total active ingredients percentage) will be the base of your serum formulation (e.g., water, thickeners, preservatives).
You don't need to calculate a specific ratio between these non-irritating ingredients other than deciding how much of each you want to include, up to their individual limits.
