Dermatology Sense

Hyaluronic acid serums are among the most effective skincare products for hydration, barrier repair, and skin plumping. Dermatologists recommend choosing a serum with multiple molecular weights of hyaluronic acid, supportive humectants like glycerin, and barrier-strengthening ingredients such as ceramides or vitamin B5. The best hyaluronic acid serum depends on your skin type, climate, and routine. When used correctly on damp skin and sealed with a moisturizer, hyaluronic acid can significantly improve skin texture, elasticity, and overall radiance.

Quick Scan

• Hyaluronic acid (HA) can hold up to 1,000 times its weight in water
• Suitable for all skin types, including acne-prone and sensitive skin
• Works best when applied to slightly damp skin
• Needs a moisturizer on top to prevent dehydration
• Multi-molecular HA formulas offer deeper and longer-lasting hydration

What Is Hyaluronic Acid and Why Is It Essential for Skin?

Hyaluronic acid is a naturally occurring glycosaminoglycan found in the skin, joints, and connective tissues. Its primary role is moisture retention.

From a dermatology standpoint, hyaluronic acid is critical because:

• It maintains skin turgor and elasticity
• Supports the skin barrier
• Helps reduce the appearance of fine lines
• Improves tolerance of active treatments like retinoids and acids

“By the age of 40, our natural hyaluronic acid levels decline significantly, which contributes to dryness, dullness, and early wrinkles.”
— American Academy of Dermatology

How Hyaluronic Acid Serums Work on the Skin

Unlike occlusives that sit on top of the skin, hyaluronic acid is a humectant, meaning it draws water into the skin.
