# Hyaluronic Acid

## Quick Summary

Hyaluronic Acid is a humectant ingredient used to help skin feel more hydrated and look smoother by binding water near the skin surface.

## What It Is

Hyaluronic Acid is the consumer parent name for this page. Sodium hyaluronate and hydrolyzed hyaluronic acid are technical label variants that can appear in formulas, but this page keeps them together under one consumer-facing Ingredient.

## Mechanism

In skincare, hyaluronic acid is best understood as a water-binding step. It can support a plumper, smoother-looking surface, but it often works best when applied to damp skin and followed with a moisturizer or cream that helps seal the feel in.
