Hardly any ingredient is as frequently associated with smooth skin as hyaluronic acid. Advertising often promises a "plumping effect," visibly reduced wrinkles, and plumper skin. However, not every wrinkle arises for the same reason. So, what can hyaluronic acid actually achieve?
Why do wrinkles appear at all?
When we talk about wrinkles, we often mean very different changes in the skin. Generally, they can be divided into various categories.
Dryness lines
They appear when the upper skin layer lacks moisture. The skin then looks more finely creased and less plump. These small lines can frequently change depending on how well the skin is moisturized.
Expression lines
They are caused by repeated movements of the facial muscles, for example, when smiling or frowning. Over the years, these wrinkles remain more visible even when relaxed.
Structural wrinkles
As we age, the connective tissue changes. The skin produces less collagen, elastin, and the body's own hyaluronic acid. As a result, it loses firmness and elasticity. These changes occur slowly over many years.
How does hyaluronic acid work on the skin?
Hyaluronic acid has a remarkable property: it can bind large amounts of water. This improves the moisture content of the upper skin layers. Well-hydrated skin often appears smoother, more supple, plumper, and more even. Precisely this effect often makes fine dryness lines appear less visible.
So, can hyaluronic acid "plump up" wrinkles?
Yes. However, mainly where lack of moisture plays a role. Dryness lines can be significantly reduced by improved hydration. The skin appears fresher and more elastic.
However, deeper wrinkles caused by the natural aging process do not disappear. Here lies an important difference:
Hyaluronic acid improves the appearance of the skin, but it does not change the structure of the connective tissue, as collagen and elastin fibers also play a role there.
Why does the skin often look fresher immediately anyway?
Many people notice a pleasant skin feeling shortly after applying a hyaluronic serum. This is because well-hydrated skin reflects light more evenly. This makes it appear more even, smoother, and often more radiant. This so-called glow does not arise because wrinkles disappear, but because the skin surface is better moisturized.
Low-molecular or high-molecular: Does it make a difference?
Hyaluronic acid comes in different molecular sizes. High-molecular hyaluronic acid primarily remains on the skin's surface. There, it forms a moisturizing film and helps reduce water loss. Low-molecular hyaluronic acid can penetrate somewhat deeper into the upper skin layers and bind water there. That's why many modern serums use low-molecular hyaluronic acid or combine different molecular sizes. However, it's not just the molecular size that's crucial, but the overall formulation and regular application.
Why is a hyaluronic serum alone often not enough?
Hyaluronic acid binds water. However, for this to remain in the skin for as long as possible, an intact skin barrier is also needed. Therefore, it is advisable to apply a suitable cream after a hyaluronic serum. It supports the skin barrier and helps reduce natural water loss. Hydration and barrier protection complement each other but do not replace each other.
Healthy Aging does not mean wrinkle-free
Healthy Aging pursues a different approach than classic anti-aging promises. It's not about making every wrinkle disappear, but about helping the skin maintain its natural functions for as long as possible. Well-hydrated skin often appears fresher, more supple, and more radiant.
However, this does not mean that natural skin aging can be stopped. And that's precisely what makes hyaluronic acid so interesting: it supports the skin where it needs moisture, without raising unrealistic expectations.
