How to Read an Ingredients List Without a Chemistry Degree
Skincare ingredient lists can look intimidating.
Long scientific names. Latin words. Ingredients you’ve never heard of. And sometimes a front label filled with hero ingredients that tells you very little about the formula as a whole.
But you don’t need a chemistry degree to understand what you’re putting on your skin.
Once you know a few simple rules, an ingredients list becomes much easier to read.
And the good news? Those rules apply whether you’re looking at a Lust product or something from another brand entirely.
Start with the back, not the front
The front of a skincare product is designed to tell you what the brand wants you to know first. The ingredients list tells you what is actually in the formula.
In Australia, cosmetic ingredients generally need to be displayed for consumers and listed according to specific labelling requirements. Ingredients at concentrations of 1% or more can be listed in descending order by mass or volume, followed by ingredients below 1% in any order, with colour additives able to appear afterwards.
That means the beginning of the list can tell you a lot about the overall structure of a formula.
The order matters
As a general rule, the ingredients appearing earlier in the list are present at higher concentrations than those that come later.
So when you’re trying to understand a product, start at the top. Rather than becoming overwhelmed by 20 or 30 ingredient names, look closely at the first few. They give you an idea of what forms the main base of the product.
You might see things like:
- Water or Aqua
- Glycerin
- Plant oils
- Emollients
- Humectants
- Cleansing agents
Then, further down the list, you may start seeing targeted skincare ingredients, botanical extracts, preservatives, fragrance ingredients or colour additives depending on the formula.
What does the 1% rule actually mean?
This is one of the most useful things to understand when reading a skincare label.
Under Australian cosmetic labelling rules, ingredients present at 1% or more may be listed in descending order of concentration.
Ingredients present at less than 1% can then be listed in any order.
The important part is this:
You generally can’t look at an ingredients list and know the exact percentage of every ingredient.
Unless a brand chooses to disclose it, the label usually tells you the order, not the precise concentration. Australian cosmetic labelling requirements do not generally require individual ingredient percentages to be shown.
So rather than trying to guess an exact percentage from the label, use the list as a guide to understanding the overall formula.
Water being first is completely normal
One of the most common ingredients you’ll see at the beginning of skincare formulas is:
Aqua. Which simply means water.
For many cleansers, moisturisers, serums and lotions, water forms the base of the product. That doesn’t mean the formula has been “watered down”.
Water can act as the medium that allows other ingredients to dissolve, combine and spread comfortably across the skin.
Oil-based products, balms and anhydrous formulas may look completely different because they don’t rely on water as their main base.
Why do ingredient names sound so complicated?
Cosmetic ingredients are commonly listed using standardised ingredient names, often referred to as INCI names.
That’s why familiar ingredients can suddenly look much less familiar once you see them written on packaging.
For example:
Tocopherol = Vitamin E
Niacinamide = Vitamin B3
Ascorbic Acid = Vitamin C
Sodium Hyaluronate = a salt form of Hyaluronic Acid
Butyrospermum Parkii Butter = Shea Butter
Simmondsia Chinensis Seed Oil = Jojoba Oil
A long or unfamiliar name doesn’t automatically tell you whether an ingredient is good, bad or appropriate for your skin. Sometimes it is simply the standard name used to identify it consistently.
Don’t judge an ingredient by how “chemical” its name sounds
This is an important one.
An ingredient having a long scientific name doesn’t mean it is inherently harsh, undesirable or unsuitable.
Likewise, an ingredient having a simple or plant-based name doesn’t automatically mean it will suit every skin type.
What matters is the full formula, how an ingredient is used and whether that particular product works for your skin.
Ingredient lists are most useful when they help you make an informed choice, especially if there are particular ingredients you know you prefer, tolerate well or need to avoid.
For people with known allergies or sensitivities, ingredient labelling is particularly important because it allows them to check whether a product contains something relevant to them.
What about words like “clean” and “natural”?
You’ll see words like clean, natural, green and conscious used throughout the beauty industry.
They can be useful for understanding how a brand thinks about formulation, but they don’t replace an ingredients list.
At Lust, our approach to clean beauty is part of our own formulation philosophy and standards. But we also believe you should be able to see what is actually inside the products you’re considering.
That’s why the full ingredient list matters. Rather than relying on one word on the front of a bottle, turn it around and look at the formula for yourself.
What about hero ingredients?
You’ll often see skincare products promoted around one or two standout ingredients.
That doesn’t necessarily mean those ingredients need to appear right at the top of the list to be meaningful.
Different cosmetic ingredients are formulated at very different usage levels.
Some are commonly used in larger amounts, while others are designed to be incorporated at much smaller concentrations.
So seeing a hero ingredient further down an ingredients list doesn’t automatically tell you whether the product is effective or well-formulated.
The ingredient list is one piece of information.
Ideally, look at it alongside the product’s purpose, directions, formulation information and any substantiation the brand provides for its claims.
What should you actually look for?
You don’t need to memorise hundreds of ingredient names.
Instead, try three simple habits.
1. Read the first few ingredients
These give you a useful snapshot of the base of the formula.
You’ll quickly start recognising whether you’re looking at a water-based moisturiser, an oil-rich balm, a foaming cleanser or something else entirely.
2. Look for ingredients that matter to you
Maybe you know your skin loves Niacinamide.
Maybe you’re looking for Hyaluronic Acid.
Maybe you have a known sensitivity and need to check for a particular ingredient.
Rather than judging the entire formula at once, start with the things that are personally relevant to you.
3. Read the whole list when you need to
Ingredient highlights are convenient.
But they aren’t the same thing as the complete ingredients list.
If knowing exactly what is in a product matters to you, look for the full list before you purchase.
Australian cosmetic ingredient labelling requirements are designed in part to help consumers make informed choices and identify ingredients they may be sensitive or allergic to.
Ingredients apps can be useful, but they aren’t the whole story
Ingredient scanning apps can make complicated labels easier to navigate.
But a formula is more than an individual list of ingredients rated one by one.
Concentration, formulation, product type and how ingredients work together all matter.
So if an app flags something you don’t recognise, use it as the beginning of your research rather than necessarily the final answer.
And if you’re unsure about something in one of our formulas, ask us.
We’d always rather explain what an ingredient is and why it’s there than leave you guessing.
You don’t need to understand every word
Reading an ingredients list isn’t about becoming a cosmetic chemist overnight.
It’s about knowing enough to ask better questions.
Look at the ingredients near the beginning. Understand that lower-level ingredients may not appear in exact concentration order. Don’t be intimidated by scientific names, and choose brands that make it easy for you to find the complete information you want before purchasing.
Every Lust product page includes its full ingredients list so you can see exactly what is in the formula before adding it to your routine.
Still unsure about an ingredient? Ask our team. We’re always happy to explain what’s in your Lust products and why it’s there.
