Hyaluron serums are among the most popular active ingredient products in modern skincare. But what exactly is behind their effectiveness? And why do hyaluron serums sometimes differ so much in their results? The answer lies primarily in three factors:
- Molecule size
- Concentration
- Quality
1. The role of molecule size
Not all hyaluronic acid is the same. It comes in different molecule sizes, each of which has a different effect on the skin:
High-molecular hyaluronic acid
The molecules of high-molecular hyaluronic acid are relatively large, which is why they remain on the skin's surface. There, they form a moisturizing film that immediately makes the skin appear smoother. The effect is visible and noticeable, but rather short-term.
Low-molecular hyaluronic acid
In low-molecular hyaluronic acid, the molecules are much smaller, which allows them to be absorbed into the skin. There, they bind moisture in the lower skin layers and provide more firmness and elasticity in the long term.
2. The role of concentration
Many products advertise particularly high hyaluronic concentrations. But it's not just the quantity that's crucial, but the formulation.
- The combination with other ingredients influences the effect
- too high a concentration makes a serum thick to sticky and impairs both spreadability and absorption
Crucial is the serum's capacity to bind water. A well-formulated serum therefore focuses on water binding, reducing interactions between active ingredients, and a balanced concentration.
3. The role of quality
In addition to molecule size and concentration, quality also plays a central role. This includes:
- Origin and purity of the hyaluronic acid
- the manufacturing process
- and the stability of the formulation
High-quality serums often use biotechnologically produced hyaluronic acid and avoid unnecessary additives.
The effect of a hyaluron serum thus strongly depends on its composition. The combination of different molecule sizes, a well-thought-out concentration, and high quality are crucial for visible results.
