The secret to plumper, firmer and younger-looking complexion, a hyaluronic acid serum benefits the skin in multiple ways. Read on to discover what hyaluronic acid serum does, how to apply it, and where to find the best hyaluronic acid serum for you.  

What does hyaluronic acid serum do? 

A chemical compound that naturally occurs in the body, hyaluronic acid helps to keep skin hydrated and plump. However, hyaluronic acid levels naturally deplete as you age, causing skin to lose moisture and fine lines and wrinkles to appear.  

A hyaluronic acid serum can help to maintain healthy levels of hyaluronic acid, keeping skin looking plump and youthful.  

Hyaluronic acid serum: benefits 

Locking in hydration 

Known as a humectant, hyaluronic acid can absorb moisture from its surroundings and drive that moisture into skinWhen applied topically, a hyaluronic acid serum helps to lock in hydration. 

Preventing moisture loss 

Capable of holding up to 1000 times its weight in water, hyaluronic acid helps the skin to retain moisture, preventing dehydration.   

Plumping the skin 

If damaged by environmental factors (pollution, UV rays or indoor heating), the skin barrier can lose its structure, resulting in dry, rough-looking skin.  

Hyaluronic acid serum can help to keep skin looking plump, soft and smooth, while fine lines and wrinkles appear reduced.  

How to use hyaluronic acid serum 

Hyaluronic acid serum should be applied morning and night after cleansing and toning, but before a moisturizer, facial oil or SPF.  

Massage into the face and neck, then allow to sink in for 90 seconds before continuing your skincare routine.
