What Is Non-Comedogenic Skincare, and Why Does It Matter for Acne-Prone Skin?
Non-comedogenic skincare refers to products formulated with the aim of minimising clogged pores. If you have acne-prone or congestion-prone skin, you've probably seen the term everywhere.
But what does non-comedogenic actually mean? Which ingredients should you look for? Do oils clog pores? And does a non-comedogenic label guarantee a product won't cause breakouts?
As with most things skin, it's not quite as simple as one word on a bottle.
What Does Non-Comedogenic Mean?
Non-comedogenic generally means a product has been formulated to minimise the likelihood of clogging pores, also known as comedones.
Pores can become blocked by a combination of oil and dead skin cells, contributing to blackheads, whiteheads and breakouts.
But here's the important bit: non-comedogenic isn't a guarantee that a product won't clog your pores.
There is no single universal standard for determining whether a skincare product is non-comedogenic, and our skin is wonderfully individual. The ingredients matter, but so do their concentrations, the complete formulation and your own skin.
How Is Comedogenicity Measured?
You've probably seen the comedogenicity scale, which traditionally ranks individual ingredients from 0 to 5:
-
0 – Very unlikely to clog pores
-
1 – Very low likelihood
-
2 – Low
-
3 – Moderate
-
4 – Moderately high
-
5 – High likelihood
It looks wonderfully straightforward. Unfortunately, skin isn't quite that simple.
Much of the traditional rating system came from testing individual ingredients rather than complete skincare formulations, and some of the early research used rabbit-ear testing (not us!) rather than human skin.
So we think of the comedogenic scale as a useful guide, not a guarantee.
An ingredient traditionally rated 3 or 4 doesn't automatically make a finished product pore-clogging, particularly if it is used at a low concentration or in a rinse-off product. And an ingredient rated 0 still can't promise to suit every person's skin.
The complete formula matters more than one number.

Why Does Non-Comedogenic Matter for Acne-Prone Skin?
If you're dealing with breakouts or congestion, it makes sense to consider the pore-clogging potential of the products you're putting on your skin.
But acne-prone skin still needs hydration, nourishment and barrier support. Choosing skincare for acne-prone skin isn't simply a matter of avoiding every oil or rich ingredient.
A few things are worth considering:
-
Clogged pores: Comedones are part of the acne process, so pore-clogging potential is relevant when choosing skincare.
-
The complete formula: One ingredient with a higher traditional rating doesn't necessarily make the finished product highly comedogenic.
-
Hydration still matters: Acne-prone skin can also be dry, sensitive or dehydrated.
-
Over-cleansing isn't the answer: Stripping the skin can leave it dry, tight and uncomfortable.
The aim is not to become frightened of ingredients. It's to understand what you're putting on your skin and find a routine that works for your skin.
Customer Review: SkinTonic
"The Best Oil Ever: I have tried all sorts of oils on my face but have always found them very heavy, clogging up my pores. I waited to write this review to be sure that the product was really benefiting my skin, and hand on heart, this oil is amazing! It's light and my skin immediately responded by feeling calmed and soft. I've had really blemished skin all my life and this oil is actually decongesting my pores. My skin has never looked better and I look forward to my daily cleansing ritual. I can't recommend this oil more highly!"

How Can You Tell if a Product Is Non-Comedogenic?
There's no single legal or universally standardised definition of non-comedogenic, so a little detective work can be useful.
-
Check the label: You may see terms such as “non-comedogenic” or “won't clog pores”, but remember these aren't a guarantee for every skin.
-
Read the full ingredient list: Don't judge an entire formula by one ingredient.
-
Consider concentration: Ingredients near the beginning of an INCI list generally make up more of a formula than those appearing near the end.
-
Think about how the product is used: A cleansing oil that emulsifies and is rinsed away is very different from applying a pure oil and leaving it on your skin.
-
Pay attention to your own skin: Because your skin gets a vote too.
💡 Tip: Sites like CosDNA or INCIDecoder can be useful for looking up individual ingredient ratings, but remember they're giving you information about ingredients, not necessarily predicting how the complete formula will behave on your skin.
Which Ingredients Should You Look For and Avoid?
This is probably one of the first things you Googled, so let's talk about it.
Ingredients With Higher Traditional Comedogenic Ratings
You'll often see ingredients such as these on lists for acne-prone skin:
-
Coconut oil
-
Isopropyl myristate
-
Lanolin and some lanolin derivatives
-
Wheat germ oil
-
Cocoa butter
But we don't love calling these simply “ingredients to avoid”.
Why?
Because comedogenic ratings are based largely on individual ingredient testing. The concentration, finished formulation, other ingredients and whether the product is rinsed off or left on the skin can all change the picture.
If you already know a particular ingredient repeatedly causes congestion for your skin, that's useful information. But seeing one higher-rated ingredient halfway down an INCI list doesn't automatically mean you need to put the bottle back on the shelf.
Ingredients With Low Traditional Comedogenic Ratings
Some ingredients commonly used in skincare have very low traditional comedogenic ratings or are lightweight ingredients that can work well within formulas designed for acne-prone skin.
These include:
-
Kōakaheart™ oil: Traditionally rated 0/5 on the comedogenic scale and the hero oil at the heart of Hark & Zander.
-
Jojoba oil: Commonly rated around 2/5 and valued for its skin-conditioning properties.
-
Squalane: Commonly rated around 0–1/5. We use plant-derived squalane from olives.
-
Hyaluronic acid: A lightweight humectant that attracts and holds water. It doesn't have an established traditional comedogenic rating.
The important thing, again, is to look at the complete formulation rather than one ingredient in isolation.
How Do You Build a Non-Comedogenic Skincare Routine?
If you have acne-prone or congestion-prone skin, you don't necessarily need to throw everything away and start again.
A simple, consistent routine that cleanses without stripping and gives your skin the hydration and support it needs is a good place to start.
Here's the ideal order:
-
Cleanser – Start with a gentle cleanser to remove makeup, sunscreen, dirt and excess facial oil without leaving your skin feeling stripped.
-
Toner – Follow with hydration. Our gel toner actually sits somewhere between a traditional toner and a lightweight serum.
-
Serum – Add targeted ingredients for concerns such as dehydration or the visible signs of ageing.
-
Day Crème or Night Crème – Support hydration and your skin barrier with a moisturiser suited to your skin.
-
Face Oil – If your skin loves an oil, apply it after your water-based products and crème.
-
SPF – In the morning, finish with a broad-spectrum sunscreen suitable for your skin.
✨ Our full ritual includes:
-
SkinTonic Face Oil - with Kōakaheart™
Rather than calling every product “non-comedogenic”, we prefer to look at the complete formula, including its ingredients, their relative concentrations and how the product is used.
Tips for Choosing Non-Comedogenic Skincare Products
-
Read the full ingredient list, not just the claims on the front.
-
Use comedogenic ratings as a guide rather than a set of rules.
-
Consider where an ingredient appears in the formula.
-
Remember that rinse-off and leave-on products behave differently.
-
Introduce new products gradually if your skin is prone to congestion.
-
Stay consistent rather than changing several products at once.
-
Listen to your skin. Even a supposedly “safe” ingredient may not suit everyone.
Can Natural Skincare Be Non-Comedogenic?
Yes, absolutely.
Being natural doesn't automatically make an ingredient pore-clogging, just as being natural doesn't guarantee that an ingredient will suit every skin.
Botanical oils vary enormously in their fatty-acid profiles, texture and traditional comedogenic ratings.
Examples of ingredients with relatively low traditional pore-clogging potential include:
-
Kōakaheart™ oil
-
Jojoba oil
-
Squalane
-
Many botanical extracts
At Hark & Zander, our approach combines carefully selected botanical and marine ingredients with considered formulation. We look at why an ingredient is there, how much we're using and what it contributes to the complete product, rather than choosing ingredients based on one number alone.
What If You Still Break Out?
Sometimes your skin can develop congestion even when you're using products marketed as non-comedogenic.
If you've recently introduced something new, consider:
-
When did the congestion begin? Did it coincide with a new skincare product?
-
Could it be another product? Makeup, sunscreen and hair products can all come into contact with facial skin.
-
Have you changed several things at once? If so, it becomes much harder to identify the culprit.
-
Is your skin irritated as well as congested? Redness, stinging or discomfort may be telling you something different from clogged pores.
-
Could other factors be involved? Hormonal changes, stress and other factors can influence acne too.
If you're unsure, simplify your routine and introduce new products one at a time. If acne is persistent, worsening or causing concern, talk to an appropriate health professional.
Skincare is one piece of the puzzle, and understanding how your own skin responds is far more useful than blindly following a comedogenic chart.
FAQ
Q: Can natural oils be non-comedogenic?
A: Some natural oils have very low traditional comedogenic ratings, while others rate higher. Kōakaheart™, jojoba and squalane are examples of oils with relatively low traditional ratings, but concentration, formulation and individual skin still matter.
Q: What's the difference between non-comedogenic and oil-free?
A: Oil-free means a product has been formulated without oils. Non-comedogenic refers to its potential to contribute to clogged pores. A product does not need to be oil-free to have a low pore-clogging potential.
Q: Is “non-comedogenic” a regulated term?
A: There is no single universally standardised testing system that guarantees a product labelled non-comedogenic won't clog your pores. That's why we think it's worth looking beyond the label.
Q: Can dry skin be acne-prone too?
A: Yes. Dryness and acne or congestion can occur at the same time, so stripping all the oil and moisture from your skin isn't necessarily the answer.
Q: What if I'm not sure which ingredients clog my pores?
A: Introduce new products one at a time and pay attention to patterns in your own skin. You can also use our Skincare Ingredient Glossary to look up the ingredients we use, their traditional comedogenic ratings where one exists, and how we assess our complete formulas.
Wrap-Up: Build Your Routine With Balance in Mind
Choosing skincare for acne-prone skin doesn't need to mean obsessing over whether every ingredient has a comedogenic rating of zero.
The comedogenic scale is useful. It just isn't the whole story.
Look at the complete formula, consider concentration and how the product is used, and most importantly, pay attention to your own skin.
At Hark & Zander, we'd rather explain what's in our skincare and why we use it than simply promise that an ingredient or formula “won't clog your pores”.
