Medicube TXA Niacinamide 15% Serum 30ml – Brightening Serum for Dark Spots & Uneven Skin Tone
Dark spots, acne marks, pigmentation, and uneven skin tone can make the complexion look dull and less radiant. If you’re looking for a targeted brightening serum, Medicube TXA Niacinamide 15% Serum 30ml combines two popular ingredients for pigmentation-focused skincare: 15% Niacinamide and Tranexamic Acid (TXA).
This lightweight facial serum is designed to help improve the appearance of hyperpigmentation, dark spots, acne scars, dullness, and uneven-looking skin tone. At the same time, Niacinamide helps support the skin barrier and improve the overall appearance of skin texture.
The fast-absorbing formula makes it convenient to use underneath moisturizer and sunscreen without leaving an excessively heavy feeling.
What Is Medicube TXA Niacinamide 15% Serum?
Medicube TXA Niacinamide 15% Serum is a concentrated brightening serum designed for people who want to address visible pigmentation and uneven skin tone.
The key combination is:
- 15% Niacinamide
- Tranexamic Acid (TXA)
Niacinamide is a versatile skincare ingredient known for supporting the skin barrier and improving the appearance of uneven tone and texture. Tranexamic Acid is commonly used in skincare products formulated to target the appearance of discoloration.
Together, these ingredients make the serum suitable for a skincare routine focused on:
- Dark spots
- Hyperpigmentation
- Post-acne marks
- Uneven skin tone
- Dull-looking skin
- Uneven-looking texture
Why Choose Medicube TXA Niacinamide 15% Serum?
Many brightening serums focus on only one concern. This formula takes a more targeted approach by combining a high concentration of Niacinamide with Tranexamic Acid.
15% Niacinamide
Niacinamide is the major active ingredient in this serum.
It can help support:
- A more even-looking skin tone
- Skin barrier function
- Improved-looking skin texture
- Reduced appearance of pores
- Healthier-looking skin
Tranexamic Acid
Tranexamic Acid is commonly used in pigmentation-focused skincare.
It helps target the appearance of:
- Dark spots
- Uneven pigmentation
- Post-acne discoloration
- Dull and uneven complexion
The combination makes this serum particularly appealing for people looking for targeted tone-correcting care.
Key Benefits of Medicube TXA Niacinamide 15% Serum
1. Targets Dark Spots
Dark spots can develop from acne, sun exposure, and other forms of pigmentation.
The combination of Niacinamide and Tranexamic Acid is designed to help improve the appearance of visible discoloration with consistent use.
2. Helps Improve Hyperpigmentation
Hyperpigmentation can cause some areas of the face to look darker than the surrounding skin.
This serum provides targeted brightening care to help create a more even-looking complexion.
3. Helps Improve the Appearance of Acne Marks
Post-acne marks can remain after blemishes have healed.
A serum containing Niacinamide and TXA can be incorporated into a routine designed to improve the appearance of these pigmentation marks.
However, pigmentation marks and textural acne scars are different concerns. A brightening serum is primarily relevant to discoloration rather than deep textural scarring.
4. Brightens Dull-Looking Skin
Dull skin can make the complexion appear tired.
Regular use of a brightening-focused serum can help skin look fresher, clearer, and more radiant.
5. Supports the Skin Barrier
Niacinamide is well known for its role in supporting the skin barrier.
A healthy barrier helps the skin retain moisture and maintain a more comfortable appearance.
6. Helps Refine Skin Texture
Niacinamide can support smoother-looking skin texture.
Combined with a consistent cleansing and moisturizing routine, it can help improve the overall appearance of the complexion.
7. Lightweight and Fast-Absorbing
The serum is designed to absorb quickly without leaving a heavy or excessively greasy feeling.
This makes it easy to layer with:
- Toner
- Moisturizer
- Sunscreen
- Other compatible skincare products
Key Ingredients & Their Benefits
Niacinamide 15%
Niacinamide, also known as Vitamin B3, is the primary active ingredient in this serum.
At 15%, it provides a concentrated approach to brightening and skin-conditioning care.
Potential skincare benefits include:
- Supporting the skin barrier
- Improving the appearance of uneven skin tone
- Helping reduce the appearance of pores
- Supporting smoother-looking skin
- Improving overall skin radiance
Because 15% is a relatively high concentration, people with sensitive skin should introduce the product gradually.
Tranexamic Acid
Tranexamic Acid is another important ingredient for this serum’s brightening focus.
It is commonly found in skincare products designed to address the appearance of pigmentation and discoloration.
It can complement Niacinamide in routines focused on:
- Dark spots
- Uneven tone
- Post-acne pigmentation
- Sun-related discoloration
Texture & Finish
Medicube TXA Niacinamide 15% Serum has a lightweight serum texture designed for quick absorption.
It is suitable for layering and can be followed by moisturizer without making the skincare routine feel unnecessarily heavy.
The intended finish is:
- Lightweight
- Fast-absorbing
- Comfortable
- Non-heavy
- Suitable for daily layering
Who Should Use Medicube TXA Niacinamide 15% Serum?
This serum can be a suitable option for people concerned about:
- Dark spots
- Hyperpigmentation
- Acne marks
- Uneven skin tone
- Dullness
- Uneven-looking texture
- Lack of radiance
It can be used by different skin types, but people with sensitive or reactive skin should introduce a high-strength Niacinamide product carefully.
Is It Suitable for Oily Skin?
Yes. The lightweight serum texture can work well in oily and combination skincare routines.
You can apply it after cleansing and toning, followed by a lightweight moisturizer if needed.
Is It Suitable for Dry Skin?
Yes. Dry skin can also use this serum, but it should be combined with a suitable moisturizer to maintain hydration and barrier comfort.
A simple routine can be:
Cleanser → Serum → Moisturizer → Sunscreen
Is It Suitable for Sensitive Skin?
The product is described as suitable for all skin types, but 15% Niacinamide is a relatively high concentration.
If you have sensitive skin, consider:
- Patch testing first
- Starting 2–3 times per week
- Using a small amount
- Avoiding broken or irritated skin
- Increasing frequency gradually if well tolerated
If significant or persistent irritation occurs, stop using the product.
Can It Help With Acne Marks?
Yes, it can be useful for post-acne pigmentation and dark marks.
However, it is important to distinguish acne marks from acne scars. Dark marks can respond to brightening skincare, while deep or textured scars generally require different treatment approaches.
Can It Help With Dark Spots?
Yes. The combination of 15% Niacinamide and Tranexamic Acid makes the product suitable for a pigmentation-focused skincare routine.
Consistent use and daily sunscreen are important when trying to improve the appearance of dark spots.
How Does It Fit Into a Skincare Routine?
A simple morning routine can be:
Cleanser → Toner → Medicube TXA Niacinamide 15% Serum → Moisturizer → Sunscreen
An evening routine can be:
Cleanser → Toner → Serum → Moisturizer
You can explore more skincare products through the Alyals BD skincare collection.

How to Use Medicube TXA Niacinamide 15% Serum?
For best results, incorporate the serum into a consistent skincare routine.
- Cleanse your face thoroughly.
- Apply toner if you normally use one.
- Apply a few drops of Medicube TXA Niacinamide 15% Serum to the face.
- Gently spread and pat until absorbed.
- Apply moisturizer.
- In the morning, finish with a broad-spectrum sunscreen.
The product’s listed directions recommend applying the serum after toner.
When Should You Use It?
The serum can be used in your morning and/or evening skincare routine.
A simple morning routine:
Cleanser → Toner → Medicube TXA Niacinamide 15% Serum → Moisturizer → Sunscreen
A simple evening routine:
Cleanser → Toner → Serum → Moisturizer
If you’re new to a high-concentration Niacinamide serum, start with a few applications per week and gradually increase frequency according to your skin’s tolerance.
How to Use It for Dark Spots?
If dark spots or post-acne marks are your primary concern, apply the serum evenly over the face rather than using a very large amount on individual spots.
You can also focus a small amount on areas with visible discoloration.
Consistent application is more important than applying excessive amounts.
Why Sunscreen Is Essential?
When your skincare routine focuses on pigmentation, daily sunscreen is extremely important.
UV exposure can contribute to pigmentation and can make existing dark spots more noticeable. Using sunscreen helps protect your skin while you’re working on improving the appearance of uneven tone.
For daytime use:
Serum → Moisturizer → Broad-Spectrum Sunscreen
You can explore the Alyals BD sunscreen collection for suitable options.
Can You Use Medicube TXA Niacinamide 15% Serum With Vitamin C?
Yes, Vitamin C and Niacinamide can be incorporated into the same overall skincare routine.
However, because this serum already contains a high 15% concentration of Niacinamide, people with sensitive skin may prefer to keep the routine simple.
For example:
Morning: Vitamin C → Moisturizer → Sunscreen
Evening: Medicube TXA Niacinamide Serum → Moisturizer
This approach also makes it easier to identify the source of irritation if your skin reacts.
Can You Use It With Retinal?
Yes, but using multiple active ingredients at the same time can increase the chance of irritation.
A simple routine would be:
Morning: TXA Niacinamide Serum → Moisturizer → Sunscreen
Evening: Retinal → Moisturizer
If your skin tolerates both products well, you can adjust the routine according to your skincare needs.
You can also check out the ARENCIA Retinal Booster Shot 30ml if you’re looking for a retinal-based product.
Can You Use It With AHA or BHA?
You can include exfoliating acids in the same overall skincare routine, but using several strong actives together isn’t necessary.
If you have sensitive skin, consider alternating them.
Example:
- Morning: TXA Niacinamide Serum
- Evening, 2–3 times per week: AHA/BHA
- Other evenings: TXA Niacinamide Serum
This gives your skin time to adjust while keeping the routine manageable.
Can You Use It With Hyaluronic Acid?
Yes.
The formula itself contains multiple forms of Hyaluronic Acid, including Hydrolyzed Hyaluronic Acid, Sodium Hyaluronate, Hydrolyzed Sodium Hyaluronate, and other Hyaluronic Acid derivatives.
Therefore, you may not need a separate Hyaluronic Acid serum.
If you do use one, it can be layered before moisturizer.

MuNira –
I’ve been using Niacinamide 10% for a few weeks, and it really helps brighten my skin and fade post-acne marks. The lightweight, non-sticky formula absorbs quickly, leaving my skin hydrated and even-toned. With regular use, my skin feels smoother, more refined, and has a subtle healthy glow. Gentle enough for daily use, it’s especially effective when layered after toner.
