Hyaluronic acid is a sugar molecule that can hold up to 1,000 times its weight in water so it plays a key role of locking moisture in our skin.

It comes in a variety of forms, from toners, essences and serums to creams, sheet masks and even injectable dermal fillers.

For topical products, molecular weight matters. A low molecular weight hyaluronic acid can reach the deeper layers of the skin, improving firmness and the appearance of wrinkles, while a high weight version hydrates the surface of the skin for a highly-coveted glow.

Who can use it? Everyone and every skin type. You can’t really go wrong as it’s naturally found in our skin and bodies so it’s non-irritating.

To choose which HA product is best for you, try a lightweight toner or serum like Huxley Grab Water Essence if you have oily or combination skin, whereas Klairs Supple Preparation Unscented Toner works hardest layered into dry skin, 7 skin style. Remember to seal in all the hydrating goodness of your products with a multitasking moisturizer. We love Dr. Ceuracle’s Hyal ReYouth HA-spiked Night Cream.
