When you think about sunscreen, do you only think of "preventing sunburn and tanning"? Actually, people’s requirements for sunscreen have long been more than that these days. When the market demand for combining sun protection and moisturizing emerged, sodium hyaluronate/hyaluronic acid became the preferred ingredient.

First, let’s figure out: What exactly is hyaluronic acid?

You can think of it as a "natural moisture-storing sponge" for your skin. It can hold 1000 times its own weight in moisture on your skin—that’s why you’ll find it in many skincare products (like serums and face masks).
 

Why Add hyaluronic acid to Sunscreen?

Traditional sunscreens protect your skin from UV rays, but they sometimes feel heavy or leave skin dry. Adding hyaluronic acid changes that. Here’s why it works so well in sunscreen formulations:

Hydrating sunscreen benefit: hyaluronic acid pulls in water and locks in moisture, keeping skin soft and comfortable all day.
Lightweight texture: It helps sunscreen spread easily without feeling sticky or leaving a white cast, making it perfect for daily use.
Stronger skin barrier: Well-hydrated skin is more resilient and less likely to get irritated by sun exposure or pollution.
Moisturizer + sunscreen in one: With hyaluronic acid, sunscreen doubles as a daily moisturizer, making skincare simple and effective.

"Sunscreen + Skincare" 2-in-1 is trending now

Brands all over the world (both domestic and international) are making these "multi-functional sunscreens"—they block UV rays while also hydrating and soothing the skin. If you go to a supermarket or shop online, you’ll often see phrases like "hydrating sunscreen" or "sunscreen with hyaluronic acid" directly on the sunscreen packaging. Brands highlight this because people really love this kind of product.
 

Do all sunscreens need to have hyaluronic acid?

Not necessarily. The core function of sunscreen is always to "block UV rays"—as long as it does that well, it’s a good sunscreen. But if you have dry or sensitive skin, or if you find regular sunscreens uncomfortable to wear, then choosing a sunscreen with hyaluronic acid will be a better option for you.
