Answering Questions about Hyaluronic Acid

Updated: Sep 11

Today, I'm answering questions about Hyaluronic Acid - found in many skincare products

How does Hyaluronic Acid work?

It is a very large carbohydrate molecule so it cannot penetrate the skin. It is water loving meaning it readily absorbs water from the air and your skin. it sits on top of the skin and forms a kind of water blanket on your skin. This layer can protect the skin and even its texture.

When do you use it?

Hyaluronic acid is found in skin creams and toners. I have even seen it in rinse off products which seems like a waste of money.

Will it cause acne?

Since it sits on the skin and draws in water, theoretically it could cause pores to clog.

Can it be used with retinol?

Yes, however, retinol- Vitamin A can cause redness and photo sensitivity. Patch test before using.

Can it irritate my skin?

Theoretically any ingredient has the potential to cause skin irritation. The more products used with hyaluronic acid at the same time, the greater the concentration and the greater the potential for a skin reaction.

Where does it come from?

Hyaluronic acid is a naturally occurring molecule in the body, however it is a synthesised ingredient for use in cosmetic products so it cannot be claimed to be naturally derived. The Hyaluronic acid used for injections is likely to be synthesised from animal products (rooster combs) and the cosmetic ingredient is more likely to be made by microbial fermentation from plant origins including soy/wheat.
