Hyaluronic Acid (HA)

 

The No.1 hydrator in skincare

HA is the No.1 hydrator for the skin. It can hold 1,000 times its weight in water, making it the best ingredient to tackle dehydration and dehydration-related problems, such as compromised skin barrier and trans-epidermal water loss (TEWL). 

However, if being applied incorrectly, HA could possibly make our skin feels even drier and prone to water loss. 

What is HA?

HA was discovered in the 70s. Despite its name as “acid”, it is not acidic. 

 

It is a type of sugar naturally produced by our body that fills up the spaces between elastin fibres and collagen in the dermis.

 

When we have enough of it, our skin will look plump, firm and bright. 

 

Like many other beneficial substances in our body, for example, elastic fibres and collagen, production of HA in our body starts to slows down as we age (usually begins at around 25 years old) and our skin will begin to get thinner and drier. 

What does HA do?

There are two types of HA, large and small:

 

Large particle HA (high molecular weight) is the best in binding water from the atmosphere to offer hydration. It does not penetrate skin and instead, it forms a permeable film at the surface to retain and trap in the moisture and hydration.

 

Small particle HA (low molecular weight) binds less water than large particle HA but can penetrate skin to increase suppleness, firmness, and prevent TEWL. Studies have proven that using small particle HA for a consecutive period of 60 days helps reduce fine lines and wrinkles. It also helps repair skin barrier and wounds to heal faster.

 

Many skincare products use a mixture of large and small particle HA or add in other powerful hydrators, for example, vitamin b5 and Saccharide Isomerate, to cover skin surface and epidermis for added hydration. 

 

Another benefit of HA is that it is a substance that is naturally present in our body so it rarely irritates our skin. 

How to apply hyaluronic acid?

Do you ever feel your skin is even drier after applying a HA toner? Have you ever applied a HA serum or moisturizer at night but your skin still feels tight in the morning? Try our tips below:  

 

Our first tip is to apply HA after using hydrating mist when your skin is damp.

 

In low humidity environments, for example in the winter or indoor space where air-conditioning and/or dehumidifier is on, HA will draw water from our body, instead of soaking water up from the air to our skin.

 

Our second tip is to apply facial cream immediately after using HA serum to lock up the moisture so that the moisturizing effect will last longer. 

 

HA works instantly and can make your skin look plumper, brighter and younger in no time.

 

Our one last trick is to apply HA after a busy long day or before any important meetings or dates to refresh yourselves! 

Conclusion

Hyaluronic acid is one of the most powerful natural ingredients for hydration. It gives our skin a youthful and glowy look by plumping, hydrating, and repairing our skin barrier. As a general rule, always apply a moisturiser to lock up the moisture in your skin after using a HA serum. It, without doubt, should be a fundamental part of your skincare routine, all year around.
