Vitamin C + Hyaluronic Acid: Why They Work Together
Yes — vitamin C and hyaluronic acid work beautifully together. Vitamin C brightens and defends the skin against daily damage, while hyaluronic acid draws in moisture to plump and soften. Used together, you get antioxidant protection and deep hydration in one routine, and the hydration helps offset any dryness vitamin C can cause.
What Each One Does
It helps to think of vitamin C and hyaluronic acid as having two different jobs in your routine.
Vitamin C is best known for antioxidant defense and brightening. It helps protect skin from the oxidative stress of everyday environmental exposure, while helping even out the appearance of skin tone. It also supports collagen, which plays into the look of firm, healthy skin.
Hyaluronic acid, on the other hand, is a humectant — its main job is drawing in and holding onto moisture. That translates to skin that looks more hydrated, supple, and plump, and the added hydration can also help soften the look of fine lines, especially the ones that get more noticeable when skin is dry.
So: vitamin C protects and brightens, hyaluronic acid hydrates and plumps. Because they're solving different problems, they complement each other rather than compete.
Why Vitamin C and Hyaluronic Acid Work So Well Together
This is really the heart of it. Vitamin C and hyaluronic acid pair so well because their jobs don't overlap — one is antioxidant defense, the other is hydration. There's no competition for the same task, which is part of why you can use them together without any conflict.
There's a practical bonus, too. Some vitamin C formulas, particularly ones built on L-ascorbic acid, can cause dryness, tightness, or mild irritation for certain skin types. Hyaluronic acid's hydrating effect can help buffer that, making a vitamin C routine feel more comfortable, especially if your skin tends to run dry.
Put together, you get a fuller picture of healthy-looking skin: vitamin C supporting a brighter, more even tone, and hyaluronic acid keeping things hydrated, plump, and smooth. Two different benefits, working side by side rather than in isolation.¹
Kakadu Plum: A Gentler Vitamin C Source
Kakadu Plum is an Australian native fruit known for its exceptionally high natural vitamin C content — it's considered one of the richest known sources of vitamin C found in nature, which makes it a compelling botanical option in skincare formulated for brightening and antioxidant support.
Because it's a botanical source, Kakadu Plum also tends to pair naturally with hydrating ingredients like hyaluronic acid, giving a formula the ability to address antioxidant support and hydration at the same time — often in a way that feels gentler on the skin.
This is exactly where Glow Vitamin C Serum comes in. Glow combines 15% L-ascorbic acid, sodium hyaluronate, and Kakadu Plum — in other words, it's a vitamin C serum with hyaluronic acid already built in, delivering antioxidant, brightening, and hydration support in one step.
How to Use Vitamin C and Hyaluronic Acid Together
You have a couple of ways to work these two into your routine.
If you're using separate products, apply them to clean, slightly damp skin, following each formula's directions — a hydrating serum can generally be layered with a vitamin C serum without issue.
Or you can simplify things with a formula that already contains both, like Glow, so you're getting antioxidant and brightening support along with hydration in a single step. If your skin wants even more hydration on top of that, you can always layer in a dedicated hyaluronic acid serum.

Frequently Asked Questions
Can you use vitamin C and hyaluronic acid together every day?
Yes. They can generally be used together as part of a daily routine. How often you use vitamin C depends on your specific formula and how your skin responds — if you notice dryness or irritation, scale back frequency and lean on hydration in the meantime.
Which goes first, vitamin C or hyaluronic acid?
If you're using separate products, apply your vitamin C serum first, followed by your hydrating product, unless the packaging says otherwise. If your serum already contains both, there's no layering decision to make.
Do you need both if your serum already has them?
No. If your serum already contains both vitamin C and hyaluronic acid, you don't need to add separate products just to get the benefits of each — a combined formula can deliver antioxidant, brightening, and hydration support in one step.
