Your guide to Hyaluronic Acid
A true workhorse ingredient that skin totally loves. Discover how hyaluronic acid leaves skin hydrated, calm, strengthened and more radiant.
A molecule naturally found in the skin which draws in water, hyaluronic acid is used in skincare products to allow moisture to bind to the skin without leaving a greasy or heavy feeling. Think of it as a drink for your skin! Read on as we share our top tips to quench thirsty, sensitive skin.

What is hyaluronic acid?
Hyaluronic acid isn't an 'acid,' like salicylic or glycolic, and it won't irritate a sensitive complexion. Instead, think of it as a supercharged magnet for moisture. What does hyaluronic acid do? It's superpower: The natural molecule is able to bind and hold onto 1000 times its weight in water. This is a great benefit for dry, parched skin in particular.
How does hyaluronic acid benefit the skin?
Recent research has shown that hyaluronic acid acts as a 'postbiotic' – which explains how it keeps skin so healthy and plump. Probiotics are the good bacteria that live on our skin and help to ensure a balanced microbiome. When our microbiota thrive, we experience happier, healthier skin, less irritation and sensitivity, and reduced flare ups.
How to use hyaluronic acid in a skincare routine?
Since hyaluronic acid is a moisture magnet, it works best when applied to cleansed, damp skin, locking in moisture and helping to prevent transepidermal water loss. At By Sarah, we source naturally-derived and cruelty free hyaluronic acid in our skin-quenching gel face mask, the Saviour Moisture Mask, offering the ultimate 'drink' for a thirsty, sensitive, dry or dehydrated complexion. Paired with moisture-boosting aloe vera extract, it lends an unbelievable dose of beneficial hydration as well as that all-important skin microbiome support. Soothing and calming, it is the equivalent of giving your skin a long, delicious, replenishing and hydrating drink whenever you need it. And whose skin doesn’t want some of that?
