Coenzyme Q10 has long been used in cosmetics. Often associated with skincare for mature skin, it also deserves attention for its role in cellular energy metabolism. Research into mitochondria helps explain why it remains an interesting ingredient in cosmetic product development.
The connection between Q10 and mitochondrial function has been understood for decades. What is worth exploring is how this knowledge translates into skincare and the development of a finished formulation.
Mitochondria: The Energy Skin Needs
Skin needs energy to maintain its functions. Mitochondria contribute to the production of ATP — the primary energy carrier used in cellular processes. They also regulate cellular responses to stress and participate in cell signalling.
Their function matters to keratinocytes, which participate in epidermal renewal, and fibroblasts, which produce components of the dermal extracellular matrix, including collagen.
Ageing and UV exposure can contribute to mitochondrial DNA damage and disrupted energy metabolism. Mitochondrial dysfunction is one of the mechanisms associated with skin ageing and interacts with other cellular processes.
The balance of reactive oxygen species also matters. At physiological levels, these molecules have signalling functions. When their production exceeds the capacity of antioxidant defences, they can contribute to damage to lipids, proteins and DNA.
What Does Coenzyme Q10 Do?
Coenzyme Q10 is a compound naturally present in the body. Within the inner mitochondrial membrane, it transfers electrons through the respiratory chain, participating in the process that supports ATP production.
It exists in two forms: the oxidised form, ubiquinone, and the reduced form, ubiquinol. Both participate in oxidation–reduction reactions.
Ubiquinol acts as a lipid-soluble antioxidant. It helps limit lipid peroxidation — the oxidative degradation of lipids — and can regenerate oxidised vitamin E.
Its involvement in energy metabolism and antioxidant protection provides a scientific rationale for using Q10 in skincare. However, adding it to a cream does not automatically improve mitochondrial function in the skin. Its effects following topical application require separate evaluation.
What Does Research on Topical Q10 Show?
Research into topical coenzyme Q10 was already underway in the late 1990s. A paper published in 1999 reported its penetration into the viable layers of the epidermis and a reduction in oxidation assessed using the study’s measurement method.
A study published in BioFactors back in 2015 showed that topical application of specific Q10 formulations increased epidermal Q10 levels and provided antioxidant effects. A separate experimental part of the study investigated the effects of Q10 on energy metabolism in cultured human keratinocytes.
This distinction matters. A result obtained in cell culture does not establish that a cosmetic product will produce the same effect in its users. Likewise, findings for the formulations tested cannot automatically be applied to every product containing Q10.
The 2015 study involved researchers affiliated with Beiersdorf. When assessing the evidence, it is important to consider the findings alongside the study design, methods and authors’ affiliations.
Q10 in Cosmetics: Why Formulation Matters
Coenzyme Q10 is highly lipophilic and has very low water solubility. Its use therefore requires appropriate incorporation into the formula and assessment of its behaviour in the finished product.
The presence of Q10 on an INCI list does not establish its stability, distribution within the formulation or availability within the skin. Relevant factors include the raw material’s properties, its concentration, the other ingredients and the overall formulation approach.
Liposomes, microemulsions and lipid carriers may be considered as ways to support Q10 delivery. They are not essential for every formulation. Their use should follow from the product’s objectives, the formula’s properties and research findings.
In practice, developing a cosmetic with Q10 involves several connected considerations:
- Appropriate incorporation and uniform distribution of the ingredient.
- Assessment of the formulation’s physical and chemical stability.
- Selection of processing parameters that deliver a consistent product.
- Verification of compatibility between the formulation and its packaging.
- Evaluation of the finished cosmetic’s efficacy.
Manufacturing Conditions and Packaging
A formulation developed in the laboratory must retain its properties when transferred to production scale. Temperature, ingredient addition sequence, mixing time and other processing parameters should account for the properties of the selected raw material and the formulation as a whole.
Packaging requires the same considered approach. An airless system or light-protective packaging may be suitable for a particular product, but selecting either does not, on its own, demonstrate stability.
The choice of manufacturing conditions and packaging should be supported by testing of the finished cosmetic. This helps assess whether the product maintains its intended properties during storage.
How Should the Benefits of a Q10 Cosmetic Be Communicated?
Ingredient science helps justify the selection of Q10. Claims about the finished product, however, should reflect the scope of the available evidence.
A hydration study may substantiate a moisturising effect, while elasticity measurements may demonstrate a change in that parameter. Neither result, on its own, proves improved mitochondrial function.
Similarly, understanding Q10’s role in the mitochondrial respiratory chain is not sufficient to claim that a cosmetic “increases cellular energy”. Such a claim would require appropriately designed studies addressing the proposed mechanism.
Product development should therefore connect three elements: a scientific rationale for ingredient selection, appropriate formulation technology and verification of the claimed effects.
Is Q10 Worth Revisiting?
Coenzyme Q10 has a well-established biological role. Research on specific formulations also supports the possibility of increasing epidermal Q10 levels and achieving antioxidant effects following topical application.
Its relevance to cosmetic development can come from making better use of existing knowledge: selecting the appropriate raw material, developing a stable formulation and evaluating the finished product’s effects.
At MG Evolution®, we connect ingredient science with formulation technology and manufacturing process development. When creating a cosmetic with Q10, we start with the intended skin benefits, then select the technological approach and methods for evaluating product performance.
