What UMF Rating Is Best for Skincare?

There is no single UMF rating proven to be best for every skincare product. For cosmetic formulation, UMF 10+ to 15+ can provide a practical starting range, depending on the product, positioning and required MGO level. Higher UMF grades offer greater MGO concentration and can support premium product positioning, differentiation and stronger ingredient claims, provided those claims are appropriately substantiated.

What UMF Rating Is Best for Skincare?

There is no universal best UMF rating for skincare. UMF 10+ or UMF 15+ are sensible starting points for cosmetic brands seeking authenticated New Zealand Mānuka honey with measurable MGO, while higher grades may support more premium positioning. The right choice depends on what the finished formulation actually needs.

For many cosmetic applications, UMF 10+ offers a practical balance between ingredient specification and commercial cost. Midlands supplies Mānuka honey across a wide range of UMF grades, allowing brands and manufacturers to choose a specification based on intended use, positioning and formulation requirements.

Midlands has supplied Mānuka honey for a range of topical and cosmetic applications, from multifloral Mānuka through to UMF 15+ and higher. Its own skincare products typically use UMF 5+, demonstrating how the appropriate grade varies with the product's formulation, target market and commercial positioning. Higher grades can also support brands looking to differentiate their products in premium skincare markets.

There is no established clinical “magic number” showing that every skincare product becomes more effective when moving from UMF 10+ to 15+, 20+ or higher.

A formulator should therefore work backwards from the finished product rather than simply buying the highest grade available. Consider the product format, target honey inclusion rate, desired MGO specification, processing conditions, stability requirements, target market and the claims the brand wants to make.

For skincare brands, it's also important to distinguish between the UMF grade of the honey ingredient and how that grade can be communicated on finished packaging. Using the UMF trademark requires a licence, and different labelling requirements apply to cosmetic products compared with jars of Mānuka honey.

What Does the UMF Rating Tell a Skincare Formulator?

UMF is a quality and rating system for genuine New Zealand Mānuka honey. Its four-factor testing considers MGO, leptosperin, DHA and HMF, providing information about potency, authenticity, shelf-life potential and quality. It does not measure the cosmetic performance of a finished cream, serum or mask.

UMF stands for Unique Mānuka Factor. The system assesses four key markers:

• Methylglyoxal (MGO): associated with the potency of the honey
• Leptosperin: an authenticity marker associated with Mānuka nectar
• Dihydroxyacetone (DHA): the precursor to MGO and an indicator relevant to MGO development
• Hydroxymethylfurfural (HMF): a quality marker that can indicate heat exposure and ageing

For a more detailed explanation of the rating system, read What Does UMF Mean?

For cosmetic brands, UMF certification provides value beyond simply listing “honey” as an ingredient. It offers greater confidence in the authenticity and quality of the Mānuka honey being purchased. However, depending on the brand's UMF licensing arrangements, MGO grading may be a more practical way to specify and communicate the potency of the honey ingredient.

What UMF does not do is test whether your finished moisturiser hydrates better, whether a cleanser performs as intended or whether one complete formulation outperforms another. Those questions need to be answered at the finished-product level.

Is UMF 15+ Better Than UMF 10+ for Skincare?

UMF 15+ contains a higher minimum MGO concentration than UMF 10+, so it represents a higher-potency Mānuka ingredient. That does not prove that a cream containing UMF 15+ will outperform one made with UMF 10+. Inclusion rate, processing and the complete formulation can all affect the finished product.

So, when comparing UMF 10 vs 15 for skin products, UMF 15+ is unquestionably the higher grade. The more important commercial question is whether your formulation benefits from specifying it.

Midlands' wider Mānuka honey grade guide positions UMF 10+ to 15+ as a useful range for businesses balancing potency and commercial cost, including skincare applications.

In Midlands' experience, skincare manufacturers may select UMF 10+ to manage ingredient costs, accommodate formulations containing several active ingredients or meet the pricing requirements of mainstream retail markets.

UMF 15+ and higher grades may be selected for different commercial reasons. These include developing premium skincare ranges, targeting luxury markets or maintaining consistency with established product lines that already feature higher-grade Mānuka honey.

The decision is therefore not simply about choosing the highest MGO concentration. It is about selecting an ingredient grade that supports the finished product's formulation, claims strategy and market positioning.

Does a Higher UMF Rating Always Mean Better Skin Results?

No. A higher UMF rating means a higher specified level of Mānuka quality factors, particularly MGO, but skincare performance depends on the finished formulation. Honey percentage, preservation, stability, other ingredients, processing, packaging and the intended cosmetic claim all need to work together.

This is where ingredient quality and finished-product efficacy need to be separated.

Choosing UMF 20+ instead of UMF 10+ changes the specification and MGO concentration of the honey you purchase. It does not tell you what happens after that honey is incorporated into an emulsion, combined with other ingredients, exposed to production conditions and packaged for a defined shelf life.

Higher grades also carry higher commercial value and are scarcer. Midlands supplies multiple Mānuka honey grades for bulk and commercial supply, so buyers can select according to their actual requirements rather than automatically defaulting to the highest number available.

For a skincare founder, this means premium positioning and technical necessity should not be treated as the same thing.

UMF 20+, 25+ or higher may make sense for a prestige concept or a formulation with a specific ingredient specification. But increasing UMF indefinitely is not a shortcut to creating a better cosmetic.

Brands developing topical products can also explore how Midlands discusses Mānuka honey as an ingredient for skincare formulations.

Is UMF or MGO More Useful When Choosing Mānuka Honey for Skincare?

MGO gives formulators a specific measure of methylglyoxal concentration, while UMF provides broader authentication and quality controls. A cosmetic developer may specify an MGO level for formulation purposes while using UMF certification to gain additional assurance around the identity and condition of the Mānuka honey ingredient.

This makes the two measures complementary rather than interchangeable.

If your product brief requires a particular MGO concentration, that number can be useful when defining the raw-material specification. UMF then provides a broader framework by assessing MGO alongside DHA, leptosperin and HMF.

Midlands explains this distinction in more detail in its guide to UMF and MGO grading.

For cosmetic ingredient buyers, the important point is that neither figure should be assessed in isolation from the finished product specification.

What Else Should Skincare Brands Consider Besides UMF?

UMF should be one part of a wider cosmetic ingredient specification. Brands should also consider inclusion rate, microbiological requirements, processing, consistency, colour, aroma, viscosity, contaminant testing, documentation, market regulations and how the honey performs within the complete formula.

A practical Mānuka skincare sourcing checklist should include:

• Product format: Is it a cleanser, cream, balm, mask or another format?
• Desired UMF/MGO: What level does the actual product specification require?
• Inclusion rate: How much Mānuka honey will be present in the finished formulation?
• Colour and aroma: Are there sensory restrictions that could affect ingredient selection?
• Microbiological specification: What limits must the ingredient meet?
• Residue and contaminant requirements: What testing is required for the destination market or customer?
• Batch documentation: Is a Certificate of Analysis required for every batch?
• Stability: Has the finished formulation been tested over its intended shelf life?
• Claims: Have cosmetic claims been reviewed for the markets where the product will be sold?
• Supply: Can the required grade and volume be supplied consistently as the product scales?

For buyers that want a deeper understanding of how authenticity, quality and traceability are managed, Midlands also outlines its approach as Mānuka honey experts.

For ingredient buyers, these controls can be just as important as the UMF number itself.

Is Skincare Mānuka Honey the Same as Medical-Grade Mānuka Honey?

No. Cosmetic or food-grade UMF Mānuka honey should not be confused with medical-grade honey intended for wound care. Medical-grade honey is produced, processed and tested under additional controls for medical use, with sterilisation, also called irradiation, commonly forming part of medical-grade wound-care production.

A high UMF or MGO number alone does not turn food-grade Mānuka honey into medical-grade honey.

That distinction is important because UMF measures characteristics of Mānuka honey; it is not a medical-device certification.

Brands developing cosmetic formulations should therefore avoid describing ordinary UMF-certified food-grade honey as “medical grade” simply because it carries a high UMF or MGO number.

The distinction also matters for claims. A cosmetic product and a medical or therapeutic product can sit within very different regulatory frameworks depending on the market where the product is sold.

How Can Midlands Help Skincare Brands Select a Mānuka Grade?

Midlands supplies New Zealand Mānuka honey across multiple UMF grades for commercial applications, including use as an ingredient in cosmetic formulations. Rather than selecting a grade on the headline number alone, buyers can discuss intended use, MGO requirements, supply volumes, documentation and other ingredient specifications with the Midlands team.

Midlands also has experience incorporating Mānuka honey into its own skincare products, including lip balm and hand cream. This practical product experience complements its bulk honey supply capabilities and gives cosmetic brands a supplier familiar with both ingredient selection and finished-product considerations.

For brands exploring finished skincare products, Midlands works with contract manufacturing partners who may be able to support additional requirements, including relevant product testing or cruelty-free claims. The availability of these options depends on the product, manufacturing partner and intended market.

Midlands' Mānuka honey capabilities include:

• Bulk Mānuka honey supply
• Multiple UMF and MGO options
• Honey supplied as an ingredient for cosmetic formulations
• Technical specifications
• In-house and independent laboratory testing
• Batch traceability
• Commercial documentation

The Midlands Mānuka honey range currently includes 15+, 20+, 25+ and 31+, with other MGO or UMF specifications available on request.

Midlands' laboratory and testing capabilities provide additional quality controls, while its integrated supply model supports commercial buyers requiring consistent, traceable supply.

The objective is not always to choose the strongest honey available. It is to choose a genuine, tested and commercially appropriate Mānuka honey specification for the product you are developing.
