Vitamin C or Hyaluronic Acid First?
If your skincare routine includes both Vitamin C and hyaluronic acid, you may have wondered which serum should come first.
With separate products, Vitamin C is typically applied before hyaluronic acid. But there is another approach: formulate the two together.
DAMDAM’s Citrus Glow Vitamin C + Hyaluronic Acid Serum combines two forms of Vitamin C with multi-molecular hyaluronic acid in one serum, using Japanese 3PE™ nanomolecular technology.
The result is one step designed to address dark spots, uneven tone and radiance while replenishing hydration.
Should you apply Vitamin C or hyaluronic acid first?
If you are using two separate products, Vitamin C generally comes first, followed by hyaluronic acid for hydration.
With Citrus Glow Vitamin C + Hyaluronic Acid Serum, there is no layering order to remember. Both are already formulated together in a single serum.
It reflects DAMDAM’s essentialist approach to skincare: rather than adding more products, complementary actives are precisely formulated in one where they can work together.
Apply 3 to 5 drops to clean, dry skin after essence, then follow with moisturizer.
Can you use Vitamin C and hyaluronic acid together?
Yes. Vitamin C and hyaluronic acid serve different but complementary roles in a skincare routine.
Vitamin C targets dark spots and uneven tone
Vitamin C is used to support a brighter, more even-looking complexion and reduce the appearance of dark spots and discoloration.
Citrus Glow uses two forms of Vitamin C, designed to work through different pathways to address visible discoloration and uneven tone.
Hyaluronic acid supports lasting hydration
Hyaluronic acid is a humectant, meaning it helps attract and retain water.
Citrus Glow uses multi-molecular hyaluronic acid to provide layered hydration across multiple levels of the skin’s surface, supporting a visibly plumper, smoother finish.
Together, the formula addresses both radiance and hydration without requiring two separate serums.
What makes Citrus Glow a Japanese Vitamin C serum?
For DAMDAM, a Japanese approach to Vitamin C is not simply about where the serum is made. It is also about how the actives are formulated and delivered.
Citrus Glow is powered by 3PE™ nanomolecular technology, DAMDAM’s Japanese formulation technology used to bring two forms of Vitamin C together with multi-molecular hyaluronic acid in one precisely engineered serum.
An effective active is only part of the equation. Stability, concentration, combination and delivery all influence how a formula performs.
Citrus Glow applies that precision to a lightweight, odor-free serum designed to visibly even tone, reduce the appearance of dark spots and provide lasting hydration. The formula stays stable without discoloration or odor, unlike most Vitamin C products.
What is 3PE™ technology?
3PE™ is DAMDAM’s nanomolecular technology used in Citrus Glow Vitamin C + Hyaluronic Acid Serum.
It brings together dual Vitamin C and multi-molecular hyaluronic acid in a stable, highly absorbent formula, allowing the serum to address discoloration, uneven tone and hydration in one step.
Instead of using a separate Vitamin C serum and hyaluronic acid serum, Citrus Glow builds both functions into one formula.
This is central to DAMDAM’s approach to Japanese skincare: precision synergy, rather than unnecessary complexity.
What does Citrus Glow do for skin?
Citrus Glow is designed for skin experiencing dark spots, post-breakout discoloration, dullness or uneven tone, while also delivering lasting hydration.
Its key benefits include:
Visibly reduces dark spots and discoloration
Dual Vitamin C targets the appearance of dark spots and uneven tone for a clearer, more uniform-looking complexion.
Brightens dull-looking skin
The formula supports radiance for skin that looks brighter and more luminous.
Replenishes hydration
Multi-molecular hyaluronic acid helps attract and retain moisture for a plumper, smoother-looking finish.
In a DAMDAM consumer-perception survey of 30 participants after one week of daily use, 97% saw improvements in dark spots and discoloration.
Where does amanatsu fit into Citrus Glow?
Citrus Glow also contains amanatsu, a Japanese citrus sourced by DAMDAM from Seiyo in Ehime Prefecture.
Amanatsu contains naturally occurring flavonoids and other antioxidants. DAMDAM uses it for its skin-conditioning and antioxidant potential. Together with two Vitamin C derivatives and Hyaluronic Acid, Citrus Glow’s formula provides full-spectrum skincare benefits.
Who is Citrus Glow for?
Citrus Glow is formulated for all skin types and is particularly suited to concerns including:
- Dark spots and discoloration
- Post-breakout marks
- Dull-looking skin
- Uneven tone
- Dehydration
- Lack of radiance
The lightweight serum is designed to provide visible brightening without irritation and can be used daily, morning or night.
How do you use a Vitamin C + hyaluronic acid serum?
Apply 3 to 5 drops of Citrus Glow to clean, dry skin, ideally after Paradisi Mist Hydrating Essence.
Smooth the serum evenly over the face and neck, then follow with moisturizer.
A simple DAMDAM routine could look like:
- Cleanse
- Hydrate with Paradisi Mist Hydrating Essence
- Treat with Citrus Glow Vitamin C + Hyaluronic Acid Serum
- Moisturize to seal in hydration
- Apply SPF as part of your morning routine
Because Vitamin C and hyaluronic acid are already formulated together, there is no additional HA layering step required.
