All About Hyaluronic Acid

Hyaluronic acid serves as a moisture magnet within the skin, both attracting and retaining many times its own weight in water. It’s created by the body to keep skin dewy and plump, but these natural reserves get depleted over time.

What Hyaluronic Acid Can Do:

• Instantly hydrates
• Visibly plumps skin
• Aids with wound healing
• Helps repair the skin barrier
• May regulate sebum production

“Because it’s a naturally-occurring substance, everyone has this as part of their own skin support system.”

How Hyaluronic Acid Works

Hyaluronic acid is something of a misnomer. Unlike exfoliating acids, like AHA and BHA, hyaluronic acid is a type of humectant, meaning it works to draw and retain moisture. It comes in a range of molecular sizes, each of which penetrate to various layers of the skin for three-dimensional hydration and plumping. It can also balance the production of sebum in those with oily skin.

Hyaluronic acid is ideal for everyone, especially those with:
• Dry and dehydrated skin
• Fine line and wrinkles
• Oily or acne-prone skin

Types of Hyaluronic Acid

Hyaluronic acid comes in different sizes, or molecular weights. The molecular weights determine how deep into skin the molecule can penetrate — basically, the smaller the molecule, the deeper it can go. Larger molecules remain closer to the skin’s surface for an immediate plumping effect.

Hydrolyzed Hyaluronic Acid

Low

Draws in moisture at skin’s surface

Sodium Hyaluronate

Low

Plumps skin and minimizes the appearance of lines and wrinkles

Sodium Acetylated Hyaluronate

High

Remains at the epidermis for long-lasting hydration

Tremella fuciformis polysaccharide*

Ultra-high

Functions as hyaluronic acid to enhance hydration and reduce moisture loss

*Certain plant-derived extracts can function as hyaluronic acid, though they may not appear as “hyaluronic acid” on the ingredient list

DID YOU KNOW

Some ingredients can stimulate your skin’s natural hyaluronic acid production!

As the body naturally produces hyaluronic acid again, certain ingredients can actually activate that process — which, again, slows down over time. The plum complex in the Plum Plump Hyaluronic Serum helps your skin synthesize its own hyaluronic acid, meaning the formula offers both hyaluronic acid on the spot as well as a long-term payoff.

WORKS WELL WITH...

Emollients
Emollients, such as squalane, work to trap moisture in the skin by filling in the gaps between cells in your moisture barrier. While hyaluronic acid can draw in moisture, the moisture can then evaporate. In replenishing the skin barrier, emollients make sure moisture stays where it belongs — so it's important to use them after hyaluronic acid.

Where you’ll find emollients: Banana Soufflé Moisture Cream, Pineapple-C Bright Serum, Avocado Melt Retinol Sleeping Mask, Avocado Melt Retinol Eye Sleeping Mask.


Occlusives
Occlusives create a sort of film over the skin’s surface in order to seal moisture into skin and prevent evaporation. These include jojoba and avocado oils. Some ingredients, such as lanolin, even pull double-duty as occlusives and emollients — meaning they both fill in the gaps and create a barrier to prevent moisture loss. As with emollients, these help maximize the benefits of hyaluronic acid.

Other Actives and Acids
Being a humectant, hyaluronic acid is in charge of drawing moisture into skin — that’s it. So it won’t interfere with other active ingredients in your skincare routine, such as vitamin C or acids, if you layer them together. You may want to apply your typical exfoliating acids, such as BHAs, PHAs, and AHAs, with or before your hyaluronic acid to ensure that the hyaluronic acid can then easily absorb into skin.
