The Natural Skincare Formulary: What Is Inside

The Natural Skincare Formulary is a studio manual for making skincare at home: 60 formulas written in percentages, a guide to 46 ingredients and the safety fundamentals behind them. It is built for people who want to understand how a product is put together, not just copy a card. This page lists what is in it chapter by chapter, who it suits and what it leaves out.

Who it suits
- Beginners who want an order to learn in. The DIY skincare for beginners page shows the three-batch plan the Quick-Start follows.
- Makers who want formulas in percentages that scale to any batch.
- People who want the reasons behind a formula: the phases, the pH and the preservative.
What it is not
- It is not medical advice, and it makes no claims about effects on skin. It teaches formulating.
- It is not a guarantee that a homemade product is safe or will last a certain time. Shelf lives are planning ranges.
- It does not include haircare formulas, a cost and pricing spreadsheet, a printable labels kit or a formula scaling workbook. These are sold separately.
- It is not a guide to selling. It tells you to learn your local rules before selling anything. For the cost arithmetic, see what a batch of handmade skincare costs to make.
