Hardly any ingredient is as well-known in skin care as hyaluronic acid. However, it is often forgotten that hyaluronic acid is not an artificially developed trendy active ingredient; it is a natural component of our body.
Among other things, it is found in the skin, connective tissue, joints, and eyes. In all these places, it performs a similar function: it binds water and helps keep tissues elastic and well-hydrated. It is precisely this property that makes hyaluronic acid so interesting for skin care.
What exactly is hyaluronic acid?
Chemically speaking, hyaluronic acid belongs to the group of polysaccharides, which are long-chain sugar molecules. It consists of repeating building blocks and can therefore bind exceptionally large amounts of water. You can imagine it as a small water reservoir: it doesn't give water to the skin, but helps bind existing moisture and keep it available. That's why hyaluronic acid is one of the best-known humectants in modern skin care.
Why does hyaluronic acid decrease in the skin with age?
Our skin changes over the course of our lives. With increasing age, various biological processes slow down. Among other things, the skin produces
- less hyaluronic acid,
- fewer natural moisturizing factors (NMF),
- fewer skin lipids,
- less collagen.
As a result, it loses moisture more easily and often appears drier or less plump. These changes are part of the natural aging process and form an important basic principle of healthy aging: to support the skin where its needs change.
High molecular vs. low molecular: the difference
An exciting aspect is the molecule size. Depending on the length of the hyaluronic acid chains, their properties differ.
High molecular weight hyaluronic acid
- remains predominantly on the skin surface,
- supports moisture supply there,
- often provides an immediately smoother skin feeling.
Low molecular weight hyaluronic acid
- has smaller molecules,
- can penetrate deeper into the upper layers of the skin,
- supports moisture binding there.
Which form is used depends on the desired formulation. Some products combine several molecular sizes, while others deliberately focus on a specific form.
Why hyaluronic acid fits so well with minimalist skin care
Hyaluronic acid has a clear goal: it supports the skin's moisture supply. Therefore, a hyaluronic serum doesn't necessarily need a long list of other active ingredients. With the Pure Hyaluronic Serum with Silver, the formula follows precisely this idea. Instead of combining as many ingredients as possible, the serum focuses on a clearly defined task: providing moisture, in a deliberately reduced formulation.
This corresponds to the conviction that good skin care doesn't have to be complicated, but comprehensible.
Hyaluronic acid is a building block, not the entire skin care
As valuable as hyaluronic acid is: it cannot meet all the skin's needs on its own. Healthy skin always benefits from the interplay of various factors. These include sufficient moisture, a stable skin barrier, daily sun protection, and care that suits the individual needs of the skin.
Precisely for this reason, hyaluronic acid is now an integral part of many skincare routines. Not as an all-rounder, but as a reliable building block within a well-thought-out overall concept.
