What "natural” ingredients really mean.

The word natural carries a comforting promise: safety, purity, gentleness. In cosmetic science, however, the source of an ingredient says nothing about its safety or performance. Arsenic is natural. So is poison ivy. Jellyfish venom, one of the most complex toxins known, is also natural.

At Upenya, we believe real skincare comes from balance. Africa’s botanicals meet proven science, and every ingredient earns its place through evidence rather than marketing.

What “natural” means

In cosmetics, natural refers to ingredients obtained directly from plants, minerals, or microorganisms through physical processes such as pressing, distillation, filtration, fermentation, or drying. These processes avoid chemical modification.

ISO 16128-1:2016 defines natural ingredients as those derived from renewable biological or mineral sources with minimal processing (ISO, 2016). Examples include marula oil, Aloe ferox gel, and honeybush leaf extract, all used in Upenya’s Youth Skincare range.

The term natural is not a legal certification, and the same ISO standard explicitly does not address human safety, environmental safety, or product claims on its own (ISO, 2016). In short, natural describes origin, not outcome.

What “natural origin” means

Natural-origin ingredients begin with a substance from nature but undergo controlled modification to improve purity, stability, or performance. Under ISO 16128, derived natural ingredients are defined as materials of greater than 50 percent natural origin by molecular weight (ISO, 2016). Examples include:

●     Cocoyl glucoside, a mild, biodegradable surfactant created from coconut fatty acids and plant sugars

●     Glycerin, derived from plant oils and refined to pharmaceutical-grade purity

These refinements make ingredients more stable, safer in formulation, and less likely to cause irritation.

What “nature-identical” means

A nature-identical ingredient is created in a laboratory but is chemically identical to a molecule found in nature. It delivers the same biological benefit without the environmental cost of large-scale harvesting or the variability of raw extracts.

Niacinamide (vitamin B3) is a well-known example. While it occurs naturally in plants, synthesised niacinamide provides consistent purity and potency. Recent research shows that niacinamide supports stratum corneum hydration and influences the skin barrier’s structure (Sjöberg et al., 2025). This is why responsible formulators often choose laboratory-produced versions: the result is greater consistency, reliability, and sustainability.

Why “natural” ingredients are not always better

Nature can be harmful

Poison ivy, scorpion venom, and jellyfish stings all come directly from nature and can cause significant harm. Natural substances can be powerful, but they are not automatically gentle or safe. Safety depends on purity, dosage, and how an ingredient interacts with skin. Dermatology publications caution that “clean beauty” marketing can be misleading when it implies that natural ingredients are inherently safe (Rubin and Brod, 2019).

Sustainability through science

Large-scale harvesting of plants can damage ecosystems and increase carbon impact. Producing nature-identical ingredients in a controlled environment can reduce environmental pressure while delivering the same benefits to the skin.

The Upenya standard

Upenya blends Africa’s botanical intelligence with rigorous cosmetic science:

●     Clinically tested in Europe under ISO and COLIPA guidelines

●     Community-benefit sourcing for marula, Aloe ferox, and honeybush

●     Nature-identical actives used where they improve performance or sustainability

We do not claim to be “100 percent natural.” We claim to be 100 percent honest. Effective, safe skincare relies on chemistry that works.

Final thought

Everything around us is made of chemical compounds. Skin, water, fruit, and air all rely on chemistry to function. What matters in skincare is not whether an ingredient is natural, but how it is made, tested, and proven to perform. At Upenya, we choose ingredients supported by evidence, not hype.

Frequently asked questions

Does “natural” mean an ingredient is safe?

No. Natural describes where an ingredient comes from, not how safe or effective it is. Many natural substances, from poison ivy to certain plant extracts, can irritate or harm skin. Safety depends on purity, concentration, and how an ingredient interacts with skin, not on its origin.

What is the difference between natural, natural-origin, and nature-identical?

Natural ingredients come straight from nature with minimal processing. Natural-origin ingredients start from a natural source but are modified to improve stability or purity. Nature-identical ingredients are made in a lab but are chemically identical to a molecule found in nature, offering consistent quality and lower environmental impact.

Is lab-made niacinamide as good as natural niacinamide?

Yes. Synthesised niacinamide is chemically identical to the niacinamide found in plants, but offers more consistent purity and potency. This is why many responsible formulators choose the laboratory-produced version.

Is Upenya a natural skincare brand?

Upenya blends African botanicals with proven cosmetic science. We use natural, natural-origin and nature-identical ingredients where each performs best. Rather than claiming to be “100 percent natural,” we focus on being honest about what works and why.
