Hyaluronic Acid Serum Benefits: Hydration and Fine Lines

Extra hydration, softer-looking fine lines and the details I look for in a serum.

For me, the appeal is the extra hydration, which can help fine lines look softer and less deep.

My skin is dry, sensitive and reactive. Hyaluronic acid attracts and holds water, helping dehydrated skin look plumper and smoother.

When I researched Hyaluronic Acid Serum, I learnt that our bodies naturally produce hyaluronic acid. It hydrates rather than exfoliates, and its molecular size affects how it works on the skin.

Why different Hyaluronates in your serum are important

Hyaluronic acid comes in different sizes and structures. Larger molecules mainly stay near the skin’s surface, where they help hold moisture. Some smaller molecules can move farther into the outer skin layers, depending on their size and the formula.

PHOEFI’s Hyaluronic Acid Serum combines four forms. Their different structures give them complementary ways of holding moisture. Here is what each brings to the formula.

Sodium Hyaluronate

Attracts and binds water, helping skin feel hydrated and look smoother.

Sodium Hyaluronate Crosspolymer

Hyaluronic acid chains joined into a larger network that holds moisture at the skin’s surface.

Sodium Acetylated Hyaluronate

A modified form that adheres well to the skin’s surface, helping it retain moisture.

Hydrolyzed Sodium Hyaluronate

Hyaluronic acid broken into smaller chains. These smaller molecules can support hydration within the outer skin layers.

The step I want you to remember

Roll the Hyaluronic Acid Serum onto slightly damp skin, then follow with your moisturiser. That order matters: hyaluronic acid attracts and holds water, so damp skin gives it extra moisture to work with. The serum adds hydration, while your moisturiser helps reduce moisture loss and keeps skin feeling nourished.

You can use it morning and evening. Personally, I use it in the morning, straight after my shower I roll the Hyaluronic Acid Serum onto my damp face before Vitamin C serum. I then follow with moisturiser, and then Rimmel BB Cream as my makeup.

PHOEFI uses only high-quality ingredients, and our serum won’t pill under makeup like some other brands can.

For me, Hyaluronic Acid Serum is a necessity. The extra hydration helps the fine lines around my eyes, between my eyebrows and below the sides of my lips look less noticeable.
