Medicube PDRN Pink One Day Serum

1. START WITH CLEAN SKIN

Begin with your usual cleansing routine. If you use toner, toner pads or a lightweight essence, apply those first. The PDRN Pink One Day Serum enters your routine as an ampoule/serum treatment step.

A simple routine can look like:

Cleanser → Toner/Pad → Essence → PDRN Pink One Day Serum → Moisturizer

During the daytime:

Cleanser → Toner/Pad → PDRN Pink One Day Serum → Moisturizer → Sunscreen

2. OPEN ONE VIAL

Carefully open one individually packaged vial when you are ready to use the product.

The individual format is designed to help preserve the formula until opening.

3. APPLY AN APPROPRIATE AMOUNT

Dispense an appropriate amount of serum and spread it evenly over the face.

You do not need to force the entire contents onto your skin in one application if that amount is more than your skin needs.

4. GENTLY HELP IT ABSORB

Spread the ampoule evenly and gently pat the skin to encourage absorption.

Avoid aggressive rubbing. Give the product a moment to settle before applying your next skincare step.

5. FOLLOW WITH MOISTURIZER

Once the ampoule has absorbed comfortably, continue with your moisturizer to complete the routine.

During the morning, finish with broad-spectrum sunscreen.

WHAT IF THERE IS PRODUCT LEFT IN THE VIAL?

Medicube recommends using the product immediately after opening.

If some serum remains, the vial can be closed again and the remaining product should be used within one day.

Do not keep an opened vial indefinitely for future routines.

HOW OFTEN CAN I USE IT?

Follow the usage guidance on the product packaging and adjust your routine according to how your skin responds.

Because this is an intensive ampoule treatment, you do not need to compensate by applying excessive amounts or unnecessarily adding multiple treatments at the same time.

WHERE DOES IT GO WITH OTHER SERUMS?

If you use more than one serum or ampoule, a practical rule is to apply products from lighter to richer texture, while also considering the instructions for each individual treatment.

You do not need several serums simply because they target different concerns. A routine can remain effective while being relatively simple.

CAN I USE IT IN THE MORNING?

When incorporated into a morning routine, finish with sunscreen.

Sunscreen is particularly important when your goal includes maintaining a more even-looking, radiant complexion because daily UV exposure can contribute to visible dullness and uneven-looking pigmentation.

IMPORTANT

• For external use only

• Avoid direct contact with the eyes

• Do not apply to damaged or actively irritated skin

• Stop or reduce use if persistent irritation develops

• Check the original packaging for the most current manufacturer instructions

• Once opened, use the vial promptly; if product remains, use it within one day

✨ VELLORA TIP ✨

An ampoule is a step in your routine, not the entire routine.

Apply it after your lighter preparation steps and before moisturizer. And if you're using it in the morning, don't forget the final step: sunscreen. A brightening-focused routine without daily sun protection is working against one of its own goals.

WHAT DOES THE TEXTURE FEEL LIKE?

Medicube PDRN Pink One Day Serum has a lightweight, fluid serum/ampoule texture designed to spread easily across the skin.

Although it is an intensive treatment, “intensive” does not mean that the formula needs to feel like a thick cream. It fits into the treatment stage of a skincare routine and can be followed comfortably with moisturizer.

HOW DOES IT FEEL ON THE SKIN?

Once spread across the face, the formula is designed to provide a hydrated, smooth and comfortable skin feel.

Rather than treating the vial like a heavy mask, apply an appropriate amount and allow the serum to settle into the skin before continuing your routine.

WHAT KIND OF FINISH SHOULD I EXPECT?

The finish is focused on making the complexion appear:

• More hydrated

• Smoother-looking

• Plumper-looking

• Fresher and more revitalized

• More radiant

The aim is a healthy, hydrated glow, rather than simply leaving a shiny layer sitting on top of the skin.

WILL IT MAKE MY SKIN LOOK “GLASSY”?

Hydrated skin naturally reflects light differently, so the ampoule can contribute to the fresh, luminous appearance often associated with Korean skincare.

However, “glass skin” should not be understood as a permanent skin condition or an effect guaranteed by a single product.

The final appearance also depends on your natural skin texture, hydration level and the other products in your routine.

WHAT IF THE SERUM FEELS LIKE TOO MUCH?

You do not need to apply more product simply because the vial contains more than your skin comfortably needs in one application.

Use an appropriate amount, allow it to absorb and continue with the rest of your routine.

If product remains after opening, follow Medicube's guidance and use the remainder within one day.

HOW SHOULD I LAYER IT?

Give the ampoule a moment to settle before applying moisturizer.

If you are layering several treatment products, adding everything at once is not necessarily better. Too many layers can make a routine feel heavy and can make it harder to understand which products your skin actually responds well to.

UNDER MAKEUP

When using the ampoule during the daytime, allow it to settle before moving on to moisturizer, sunscreen and makeup.

Using an appropriate amount and allowing each layer time to settle can help prevent an unnecessarily heavy skincare base.

✨ VELLORA TIP ✨

Don't judge a serum by how much you can feel sitting on your face.

A heavier or stickier finish does not automatically mean a treatment is working better. With this ampoule, focus on comfortable hydration, smooth layering and consistent use rather than trying to create the thickest possible layer.

This intensive ampoule combines several skincare ingredients, but Medicube specifically highlights Salmon PDRN, 285 Da Collagen and Glutathione as the key ingredients of the PDRN Pink One Day Serum.

Here is what each one actually means.

SALMON PDRN — REVITALIZING SKINCARE

PDRN stands for Polydeoxyribonucleotide.

In the ingredient list, the PDRN used in this formula appears as Sodium DNA.

Medicube describes its Salmon PDRN raw material as having 99% purity.

This is an important distinction:

99% purity does NOT mean that 99% of this serum is PDRN. According to Medicube's official ingredient information, Sodium DNA is present at 1 ppm in the formula.

The “99%” refers to the purity of the PDRN ingredient itself before it becomes part of the complete cosmetic formula.

Within this ampoule, Salmon PDRN forms part of the product's approach to helping skin look healthier, smoother, more radiant and revitalized.

285 DA COLLAGEN — HYDRATION & PLUMP-LOOKING SKIN

Medicube specifically highlights 285 Da Collagen in this formula.

“Da” means Dalton, a unit used to describe molecular weight. The brand describes this as an ultra-low-molecular collagen ingredient.

In a cosmetic serum, collagen can contribute to the formula's hydrating and skin-conditioning effects, helping the surface of the skin feel smoother and appear more plump.

But there is an important difference between topical collagen and the collagen naturally present inside your skin.

Applying a collagen-containing cosmetic does not mean that the product simply replaces lost structural collagen inside the skin.

GLUTATHIONE — RADIANCE & UNEVEN-TONE CARE

Glutathione is another ingredient specifically highlighted by Medicube in this ampoule.

Here, it is incorporated into a formula designed to support a brighter, more radiant and even-looking complexion.

“Brightening” in skincare does not mean bleaching the skin or changing your natural skin colour.

The goal is to improve the appearance of dullness and uneven-looking tone, helping the complexion appear fresher and

more luminous.

WHAT ELSE IS IN THE FORMULA?

The complete formula contains more than the three ingredients highlighted on the front of the product.

Medicube's official ingredient list also includes skincare ingredients such as Niacinamide, Elastin and multiple forms of Hyaluronic Acid, among many other components required to create the complete formula.

We separate these from the three ingredients above because Salmon PDRN, 285 Da Collagen and Glutathione are the ingredients Medicube specifically highlights as the key ingredients for this product.

WHY COMBINE THEM?

Think of the formula as targeting several visible characteristics of dehydrated and dull-looking skin at the same time:

Salmon PDRN → revitalizing skincare approach285 Da Collagen → hydration and plumper-looking skinGlutathione → radiance and uneven-tone care

The complete formula then supports the texture, hydration and overall cosmetic experience of the ampoule.

DOES MORE PDRN AUTOMATICALLY MEAN BETTER RESULTS?

No. Ingredient percentages, molecular sizes and marketing numbers cannot be interpreted independently as a guarantee of performance.

A finished cosmetic product depends on its complete formulation, how it is used and how an individual's skin responds.

This is also why the 99% purity claim should never be confused with the concentration of PDRN in the finished serum.

✨ VELLORA TIP ✨

When you see an impressive percentage on skincare packaging, always ask:

“99% of what?”

Here, it means 99% purity of the Salmon PDRN raw material — not a serum made from 99% PDRN.

Understanding that difference helps you compare skincare based on what the formula actually contains rather than simply choosing the biggest number on the package.

Medicube PDRN Pink One Day Serum is designed as an intensive ampoule treatment for skin that needs more than basic hydration — particularly when the complexion looks dehydrated, dull, uneven or less plump.

THIS MAY BE A GOOD CHOICE IF…

You are looking for a treatment focused on:

• Dehydrated or moisture-depleted skin

• Dull or tired-looking complexion

• Uneven-looking skin tone

• Skin that appears less plump or revitalized

• Smoother-looking skin texture

• Extra radiance and hydration

• An intensive treatment to complement your regular skincare routine

• A Korean skincare formula featuring Salmon PDRN, 285 Da Collagen and Glutathione

Medicube currently lists the product for combination, oily and dry skin.

IS IT ONLY FOR MATURE SKIN?

No. PDRN skincare does not have a required starting age.

The more useful question is whether the concerns targeted by the formula match what your skin actually needs.

Someone with dull, dehydrated or uneven-looking skin may be interested in this treatment regardless of age, while someone without those concerns does not need to add it simply because PDRN is popular.

WHAT IF MY MAIN CONCERN IS DEHYDRATION?

This product can make sense if hydration is one of your priorities.

Medicube specifically positions the ampoule around intensive hydration and glow, alongside its other cosmetic benefits.

Remember, however, that a hydrating serum does not necessarily replace moisturizer.

Your serum provides the treatment step; your moisturizer can then help complete the routine.

WHAT IF MY SKIN IS OILY?

Hydration and oil production are not the same thing. Oily skin can still experience dehydration, so having oily skin does not automatically mean you should avoid hydrating products.

Medicube includes oily skin among the skin types listed for this ampoule.

WHAT IF I HAVE SENSITIVE SKIN?

Medicube's current main product page specifically lists combination, oily and dry skin, so we are not going to independently label the product “for sensitive skin” when the brand's primary listing does not.

If your skin is particularly reactive, introduce new products carefully and pay attention to how your skin responds.

Persistent burning, redness or irritation should not be interpreted as evidence that a skincare product is “working.”

IS THIS A DARK-SPOT TREATMENT?

The formula is positioned for uneven-looking tone and radiance, but that does not mean every type of pigmentation or dark spot will respond in the same way.

Visible pigmentation can have different causes, and cosmetic skincare has limitations.

Think of this product as supporting a brighter, more even-looking complexion, rather than promising permanent removal of pigmentation.

DO I NEED THIS IF I ALREADY USE ANOTHER PDRN SERUM?

Not necessarily. Having two products containing PDRN does not automatically make a routine twice as effective.

For example, Medicube's PDRN Pink Peptide Serum and this PDRN Pink One Day Serum are different products with different formats and positioning — but that does not mean everybody needs both in the same routine.

Choose according to your actual skin concerns and the role you want the product to perform.

THIS MAY NOT BE THE BEST CHOICE IF…

• You are already satisfied with a simple hydrating serum and do not need another treatment step

• Your skin is currently irritated or compromised and you are introducing several new products simultaneously

• You expect PDRN skincare to permanently restructure your skin

• You expect instant or identical results for everyone

• You are buying it only because PDRN is trending rather than because the product matches your concerns

✨ VELLORA TIP ✨

A trending ingredient is not automatically a missing step in your routine.

Start with your concern first:

“What am I trying to improve?”

Then choose the ingredient and product that make sense for that goal. That's much more useful than building a routine around whatever ingredient happens to be popular this month.

PRODUCT TYPE

Intensive Korean serum/ampoule treatment with individually packaged vials, formulated for hydration, radiance, uneven-looking skin and a smoother, plumper-looking appearance.

WHERE DOES IT GO IN MY ROUTINE?

Use it during the treatment stage of your skincare routine, after cleansing and lighter preparation steps and before moisturizer.

A simple routine can look like:

Cleanser → Toner/Pad → Essence → PDRN Pink One Day Serum → Moisturizer

During the daytime, finish with broad-spectrum sunscreen.

INDIVIDUALLY PACKAGED FORMAT

Each vial is individually packaged to help maintain the formula until it is opened. Medicube recommends using the serum immediately after opening.

If product remains, close the vial again and use the remaining serum within one day rather than storing an opened vial for an extended period.

HOW MUCH SHOULD I APPLY?

Use an appropriate amount and spread it evenly over the skin.

An individual vial does not mean you must force the entire contents onto your face in a single application if your skin does not need that amount. More product does not automatically produce better results.

STORAGE

• Keep the product in a cool, dry place

• Avoid unnecessary exposure to direct sunlight and excessive heat

• Keep unopened vials properly sealed until use

• Once opened, use promptly

• If product remains after opening, use it within one day

• Keep out of reach of children

• Follow any additional storage instructions printed on the original packaging

HYGIENE & APPLICATION

Use clean hands when handling and applying the product.

Avoid touching the opening unnecessarily or allowing it to come into contact with unclean surfaces.

Do not apply directly into the eyes.

IMPORTANT PRECAUTIONS

• For external use only

• Avoid direct contact with the eyes

• Do not apply to damaged or actively irritated skin

• Discontinue or reduce use if persistent irritation develops

• Check the original packaging for the manufacturer's most current precautions and directions

• Use sunscreen as the final step of your daytime skincare routine

INGREDIENT INFORMATION

Medicube currently highlights Salmon PDRN, 285 Da Collagen and Glutathione as key ingredients in this formula.

The complete ingredient list contains additional ingredients, and cosmetic formulas can occasionally be updated by manufacturers.

If you have known allergies or ingredient sensitivities, always check the ingredient list printed on the product you actually receive before use.

ABOUT THE “99% PURE PDRN” CLAIM

This deserves repeating because it is very easy to misunderstand. Medicube's 99% purity statement refers to the purity of the Salmon PDRN raw material.

It does not mean that 99% of the finished ampoule consists of PDRN. Medicube's official ingredient information lists Sodium DNA at 1 ppm in the finished formula.

WHAT THIS PRODUCT CAN — AND CANNOT — DO

This is a cosmetic skincare product.

It is designed to help improve the appearance of hydration, radiance, uneven-looking tone, smoothness and plumpness.

It should not be interpreted as a medical PDRN treatment, an injectable treatment, or a guarantee of permanent structural changes to the skin.

Individual results can vary.

✨ VELLORA TIP ✨

Those tiny individual vials have a practical advantage: you aren't repeatedly opening the same large bottle throughout the treatment period.

But once a vial is opened, don't treat it like a regular serum bottle sitting in your bathroom for weeks. Use it promptly and, if some remains, follow Medicube's instruction to finish it within one day.
