Introduction Microcirculation is a fundamental component of our skin health, but it is often underestimated. It describes the flow of blood through the smallest vessels in our body, known as capillaries. These delicate structures have a diameter of only 5 to 8 micrometres and enable the direct exchange of oxygen, nutrients and metabolic products between…

Definition and properties of microemulsions In 1943 the first microemulsions were produced by HOAR & SCHULMAN. They first described the formation of stable, optically clear, liquid systems after adding an alcohol to a defined mixture of water, oil and a soap. In 1959, SCHULMAN et al. then coined the term microemulsion for such systems. Microemulsions…

What do we mean by micronutrients? Nutrients enable the body to run smoothly through all metabolic processes and thus make a positive contribution to health. They enter our body through the food we eat. A distinction is made between macro- and micronutrients. Macronutrients such as proteins, carbohydrates, and fats act as energy suppliers for our…

Microorganisms, also known as germs, are animal or plant microscopic organisms that are invisible to the naked eye. Microorganisms include bacteria, viruses, protozoa and fungi. They can exist as vegetative forms, characterised by metabolic activity, or as spores, which are their permanent form. These carry genetic material but do not carry out any metabolism. Microorganisms…

The development and safety of modern cosmetic products depends not only on innovative formulations, but also on the right packaging. This is because complex interactions can occur between the contents and the packaging material, which are summarised under the terms diffusion, sorption, migration and permeation. Migration in particular plays a central role in the cosmetics…

We also present some minoxidil-like active ingredients that have been tested for their effectiveness in promoting hair growth.   What is minoxidil?…

Hardly any other topic has shaped the 2026 active ingredient trade shows as much as the skin’s cellular powerhouses. Under the buzzword #MitochondrialBeauty, the spotlight is turning to a new generation of active ingredients that target not symptoms, but the energy metabolism of skin cells. This article explains what lies behind the concept, which raw…

Modern cosmetics are changing their perspective on skin aging. For a long time, the focus was primarily on visible signs such as wrinkles, loss of elasticity, pigmentation changes, or dry skin. Today, research is increasingly directed toward processes that begin much earlier and at a deeper level—at the cellular level. One of the most exciting…

Time and again, mineral oils from newspaper inks or cardboard packaging end up in food or cosmetic products as part of the recycling process. In this context, a distinction is made between three compounds: MOAH stands for the abbreviation “Mineral Oil Aromatic Hydrocarbons”. These mineral oils consist of 15 to 20 percent aromatic hydrocarbons. MOSH,…

The skincare industry is currently undergoing one of the biggest transformations in recent decades. Today’s consumers want more than just smoother skin; they want holistic solutions that preserve the skin’s biological youthfulness. Current anti-ageing trends clearly show that modern formulations need to go deeper. Cell energy, senescence, barrier strength, microbiome and longevity are playing an…
