Making your own skincare is more than following a list of ingredients. Good hygiene is one part of responsible formulation, alongside appropriate preservation, packaging and process control.
You do not need a professional laboratory to learn home formulation, but you do need accurate measurements, suitable equipment, good hygiene and a methodical approach.
This is where you will find my DIY skincare recipes, together with the practical formulation knowledge that helps you make them more confidently and consistently.
What Do You Need to Make DIY Skincare?
The equipment you need depends on the type of formulation you are making. An anhydrous balm, facial oil, clay mask and emulsion will not require exactly the same tools.
The goal is not to collect every piece of cosmetic equipment. It is to have the right tools for the formulation you are working with.
Accurate Measuring
Accurate measuring is one of the foundations of repeatable formulation.
A precision digital scale allows you to work in grams and, more importantly, to work with percentages. This makes it possible to resize a formulation, compare batches and document exactly what you made.
You may need:
- Digital scale with 0.01 g readability — useful for weighing small batches and ingredients used at low percentages
- Pipettes — useful for small quantities of liquids
- Watch Glass Beaker — for preparing individual ingredients
For consistent formulation, work with grams and percentages rather than spoons, cups or approximate measurements.
Mixing Equipment
The appropriate mixing method depends on the formulation.
Simple anhydrous products may only require a spatula or stirring rod, while emulsions may require more controlled mixing and shear.
Useful basic tools may include:
- Glass stirring rods
- Cosmetic spatulas
- Small mixing tools
- A mini mixer or suitable immersion blender for certain formulations
- Small weighing containers
Choose equipment that is easy to clean, suitable for cosmetic ingredients and appropriate for the size of your batch.
Heating and Temperature Control
Some formulations require controlled heating to melt waxes, butters or emulsifiers or to prepare separate phases before combining them.
A thermometer and heat-resistant vessels help you monitor the process rather than relying on guesswork.
Useful equipment can include:
- Digital Thermometer — for checking ingredient and phase temperatures
- Heat-resistant glass beakers — when working with heated phases
- Suitable small-scale heat source — depending on the formulation
Not every skincare formulation needs heat. Always follow the processing requirements of the specific formula.
Choosing Your Skincare Ingredients
Ingredients are not interchangeable simply because they appear to have similar cosmetic benefits.
A botanical oil, humectant, emulsifier, preservative or botanical extract performs a different role in a formulation and has its own technical characteristics.
Depending on the recipe, you may work with:
- Carrier oils
- Butters
- Waxes
- Hydrosols and other water-based ingredients
- Clays
- Emulsifiers
- Humectants
- Botanical extracts
- Preservatives
- Essential oils or other fragrance materials, where appropriate
Before choosing or substituting an ingredient, consider its function, solubility, compatibility and processing requirements. An ingredient should not be selected simply because it is described as “natural,” “hydrating,” or “good for sensitive skin.” Its function, solubility, recommended use level, compatibility, processing requirements and impact on the finished formula all matter.
For more information about cosmetic ingredients and their formulation characteristics, visit the DIY Skincare Ingredients guide. Ingredient origin alone does not determine whether an ingredient is suitable, safe or sustainable. If you want to explore that distinction further, read my guide to natural vs. synthetic ingredients in cosmetics.
pH Testing
pH becomes particularly important when working with water-containing formulations or products designed to remain within a specific pH range.
Depending on the formulation, you may use:
Use strips only when their measurement range matches the expected pH of the formula. A pH meter may be more useful when a formulation requires finer adjustment.
pH measurement is not necessary for every anhydrous product, but it can be an important part of developing and checking many water-based formulations.
If a recipe includes pH adjustment or testing, follow the method given for that particular formulation.
Hygiene and Workspace
Every batch should start with a clean, organised workspace.
Useful supplies can include:
- Isopropyl Alcohol For Technical Use — where suitable for the intended surface or equipment
- Spray bottle — for applying appropriate cleaning or disinfecting products
- Lint-free wipes or paper towels
- Disposable gloves — where appropriate
Cleaning and disinfection are not the same thing, and alcohol does not make a formulation automatically microbiologically safe. Good hygiene is one part of responsible formulation, alongside appropriate preservation, packaging and process control.
Packaging
Packaging is part of the formulation rather than an afterthought.
The container should be compatible with the formula and practical for its intended use.
Depending on the formulation, you may use:
- Cosmetic jars
- Bottles
- Pump bottles
- Treatment pumps
- Dropper bottles
- Airless packaging
- Other suitable cosmetic containers
Packaging can reduce exposure to air, light or repeated hand contact, but it does not replace an appropriate preservation system or stability assessment. Water-containing products may require particular attention to container design, product protection and hygienic use. Packaging also has an environmental cost beyond the formulation itself. My guide to cosmetic packaging waste looks at why recycling alone does not solve the problem and what to consider when choosing containers.
The best packaging is not simply the one that looks attractive. It should help protect the formulation and support appropriate use throughout the product’s intended storage period. Proper storage matters too, especially for oils, antioxidants and other ingredients sensitive to heat, light or oxidation. Learn how to store cosmetic ingredients to help protect your raw materials between formulation sessions.
Find a DIY Skincare Recipe
Once you understand the basic principles, you can move from individual ingredients to complete formulations.
The DIY Skincare Recipe Library is where you can browse the available formulations and choose a recipe based on the type of product you want to make, the formulation system and your current experience. If you are ready to start making, try a simple shimmering dry oil, or natural lip balm, then move on to more structured formulations as your skills develop.
You can use the Library to move through the process:
Choose a formulation → calculate your batch → make the product → document the result
Each recipe provides the information needed for that specific formulation, including the ingredients, percentages, equipment, method, processing instructions, packaging, storage and relevant safety information.
What You Will Find in My Recipes
The exact information varies according to the formulation, but recipes may include:
- Formulation snapshot
- Ingredients, INCI names and percentages
- The role of each ingredient
- Why the formulation works
- Step-by-step method
- Processing details
- Packaging recommendations
- Storage information
- Scent information, where relevant
- Possible substitutions
- Safety considerations
- Formulation notes and decision points
- Frequently asked questions
Some recipes may also include a Shop This Formulation section with links to the ingredients, equipment or packaging specifically needed for that recipe.
From Recipe to Your Own Formula
A recipe is a starting point for learning formulation, not just a list of ingredients to copy.
When you make a batch, record what you actually used. This becomes particularly important when you change the batch size or make a substitution.
For each formulation, you can record:
- Batch size
- Ingredient name and INCI
- Percentage
- Weight in grams
- Supplier
- Lot or batch information, where relevant
- Processing temperatures
- Mixing or processing observations
- pH, where relevant
- Packaging
- Date made
- Final appearance, texture and sensory observations
- Changes you would make in a future batch
Working this way turns a recipe into a repeatable formulation record.
You can use the DIY Skincare Recipe Library to find a formulation and then document your own batch as you work through it.
Learn How Skincare Formulation Works
DIY skincare becomes much easier to understand when you learn how ingredients behave and how formulation choices affect the final product.
Explore the related resources:
- DIY Skincare Ingredients — learn about ingredient groups, functions and formulation characteristics.
- Botanical Library — explore plant identity, extraction, transformation and the use of botanical materials in skincare.
- Sustainable Beauty Practices — understand the environmental aspects of packaging, waste, water use and ingredient choices.
Together, these resources help connect ingredient knowledge, formulation practice and sustainability rather than treating them as separate topics.
