Hyaluronic acid: The miraculous molecule of deep hydration

June 5, 2025|Milagros Oria Prieto

When we talk about ingredients that truly make a difference in the skin, hyaluronic acid is one of the great favorites. This polysaccharide, naturally found in our body, has earned its fame for its incredible ability to retain moisture. But it’s not just that: it also helps to smooth fine lines, improve skin elasticity, and give it a plumper, more youthful appearance. Best of all, it is perfect for all skin types, even the most sensitive.

In this article, we will explore everything you need to know about hyaluronic acid. We will discuss what it is, how it works, and why it is so essential in your skincare routine. Additionally, you will discover how divain. Care has included this magical molecule in its products to help you achieve more hydrated and healthy skin.

What is hyaluronic acid and why is it so special?

Hyaluronic acid, also known as hyaluronan, is a component naturally found in the skin, eyes, and connective tissue. In our skin, its main function is to retain moisture and provide volume.

What really makes it special is its ability to attract and hold water, up to 1000 times its weight! Basically, it works like a sponge, drawing moisture from the environment and the deeper layers of the skin, bringing it to the surface. This helps keep the skin hydrated, soft, and flexible.

As we age, the amount of hyaluronic acid in our skin decreases due to sun exposure, pollution, and other environmental factors. As a result, the skin becomes drier, loses volume and elasticity, and fine lines begin to appear. Applying hyaluronic acid topically helps reverse these effects by replenishing hydration and improving skin texture.

The multiple molecular weights of hyaluronic acid

Hyaluronic acid is not just one. In skincare, different forms are used depending on their molecular weight, and each has specific benefits:

High molecular weight hyaluronic acid: These molecules are larger, so they cannot penetrate deeply into the skin. However, they form a moisturizing film on the surface, helping to prevent water loss and giving the skin an immediate plumping effect.
Medium molecular weight hyaluronic acid: Penetrates a bit deeper than the high molecular weight type. It targets the middle layers of the epidermis, providing lasting hydration and improving the skin barrier.
Low or very low molecular weight hyaluronic acid (fragmented or hydrolyzed): These molecules are much smaller, allowing them to reach the deeper layers of the epidermis and even the dermis. From there, they help stimulate collagen production and fill wrinkles from within.

The best formulas combine these different types of hyaluronic acid to offer deep, multi-level hydration, addressing multiple layers of the skin.

Key benefits of hyaluronic acid for the skin

Intense and lasting hydration: Hyaluronic acid is excellent for keeping the skin hydrated throughout the day, trapping moisture and preventing it from evaporating.
Plumping effect: By attracting moisture from within, it smooths fine lines and wrinkles, providing an immediate plumping and softening effect.
Improves elasticity and firmness: Well-hydrated skin is more elastic. Hyaluronic acid helps maintain the skin’s structure and firmness.
Softens texture: Thanks to its moisturizing ability, the skin feels softer and smoother to the touch.
Strengthens the skin barrier: It helps maintain the skin’s protective barrier, making it more resistant to harmful environmental factors.
Cell regeneration: Low molecular weight forms aid in skin repair and regeneration processes, improving its overall appearance.
Suitable for all skin types: From dry to oily skin, hyaluronic acid is beneficial for all skin types, even sensitive ones.
Enhances the effectiveness of other active ingredients: Well-hydrated skin absorbs other active ingredients better, improving the results of your full routine.

Always remember to seal in hydration with a suitable cream and, during the day, do not forget sunscreen.
