A 5% niacinamide pad and a 10% niacinamide serum are not interchangeable just because both put niacinamide and dark-spot concerns on the label. The percentage is one useful cue, but the product format, companion ingredients, and intended routine step tell you more about how the product fits your existing routine.
For this comparison, the practical choice is between a toner-format pad with a 5% niacinamide label and an ampoule/serum with a 10% niacinamide label. Both Anua products also name TXA, but their labels point to different formats and formula details. If you want one product, start by choosing the step you need: toner pad or serum. If you want to use both, assess them as two distinct steps rather than treating one as a duplicate of the other.
What the 5% and 10% labels can—and cannot—tell you
The product names identify the concentration cues: Niacinamide 5 TXA Brightening Pad and Niacinamide 10 TXA 4 Serum for Brightening and Dark Spots. The pad also states “NIACINAMIDE 50,000ppm” on its product page.
A higher number on a product name does not, by itself, establish that a product will work faster for dark spots or uneven-looking tone. It also does not tell you how the rest of the formula feels on skin, which step it replaces, or whether you will prefer using that format consistently. The supplied product information does not provide a head-to-head comparison of 5% versus 10% niacinamide used alone, so a label-based decision should not turn the percentage difference into a promised performance difference.
Instead, read the whole label in this order:
- Format and routine step: Is it a toner pad or an ampoule/serum?
- Companion ingredients: What else is named alongside niacinamide?
- Concern stated on the label: Does the product specifically address dull-looking skin, uneven-looking tone, or the appearance of marks?
- Application design: Does the format have a feature that matters to where you want to use it?
- Price and whether you need one step or two: A lower-priced product is not automatically better value if it does not fit the step you are trying to fill.
Comparing 5% and 10% niacinamide product formats
| Buyer criterion | 5% toner pad | 10% serum |
|---|---|---|
| Product format | Toner pad | Ampoule/serum |
| Niacinamide cue on label | “Niacinamide 5”; also labeled 50,000ppm niacinamide | “Niacinamide 10” in the product name |
| Other named formula components | TXA, Pink Vitamin B12, and PHA | TXA 4 in the product name; ceramides and hyaluronic acid are named in the product description |
| Label focus | Visibly brightening dull-looking skin, uneven tone, and a smoother, hydrated look | The appearance of breakout-prone marks and uneven-looking tone, while keeping skin feeling comfortable and moisturized |
| Format-specific detail | Half-moon shape designed to fit along the under-eye and cheekbone area | No comparable applicator feature is stated in the supplied product information |
| Listed price | $23 | $24 |
The most important difference is format. The pad occupies the toner step, while the serum occupies the ampoule/serum step. That gives them separate roles in a routine without requiring an assumption that one concentration is universally better than the other.
Recommendation: choose the pad when a toner-format step is the priority
Anua Niacinamide 5 TXA Brightening Pad is the more direct fit if you are looking specifically for a toner-format product rather than a serum. Its formula is described as combining niacinamide, TXA, Pink Vitamin B12, and PHA to help visibly brighten dull-looking skin, improve the appearance of uneven tone, and support a smoother, hydrated look.
Its half-moon pad shape is designed to adhere along the under-eye and cheekbone area, where the product page notes skin can be delicate and dry. That is a format consideration, not proof of a result: it matters if you prefer a pad that can sit along those facial areas rather than a leave-on serum format.
PHA is also a meaningful label difference. The pad includes PHA, while the serum description provided here highlights ceramides and hyaluronic acid instead. Buyers who are comparing formulas beyond the niacinamide percentage should note that these are not like-for-like ingredient lists. If PHA is a concern in your current routine, check the full ingredient list and your other products before buying.

Recommendation: choose the serum when an ampoule/serum step is the priority
Anua Niacinamide 10 TXA 4 Serum for Brightening and Dark Spots is the more direct fit if you want an ampoule/serum format with a 10 niacinamide label. The product is described as containing ceramides and hyaluronic acid to keep skin feeling comfortable and moisturized while targeting the appearance of breakout-prone marks and uneven-looking tone.
This makes the serum label especially relevant when your main buying criteria are an ampoule/serum step, the appearance of marks after breakouts, and uneven-looking tone. Anua also tags the serum for dark spots, uneven skin tone, and radiant, glowy-looking skin.
The serum’s formula description names ceramides and hyaluronic acid, while the pad description names Pink Vitamin B12 and PHA. Neither list proves one format will suit every skin type better. It does give you a concrete way to compare the formulas: choose the serum when the stated comfort and moisture-oriented ingredients matter more to you than a pad format with PHA.
The product page notes that the serum has been safely tested, while also stating that individual skin differences may cause sensitivity. That is a reason to treat personal tolerance as a buying check rather than assuming that 5% or 10% will suit everyone in the same way.
The listed price is $24 on Anua’s product page.
When using both formats makes sense
Using both products is a format-based choice: the pad is categorized as a toner, and the serum is categorized as an ampoule/serum. They therefore occupy different routine steps rather than being two versions of the exact same product.
states that using the pad and serum together improved the appearance of skin clarity by 1.56 times compared with using the pad alone. This is a brand-stated comparison against the pad alone; it does not show how either product compares with other niacinamide products, nor does it prove that every user will see the same change.
For buyers deciding between one product and two, the useful question is simple: do you want to add a toner-pad step and a serum step, or are you trying to fill only one of those slots? At the listed prices, buying both is a $47 purchase before any applicable taxes or shipping shown at checkout.
Decision rule: select the routine step first, then the label details
Choose the 5% toner pad if you want a toner-format pad, value the half-moon application shape for the under-eye and cheekbone area, and want a formula that names TXA, Pink Vitamin B12, and PHA alongside niacinamide.
Choose the 10% serum if you are shopping for an ampoule/serum step and want the product description’s focus on ceramides, hyaluronic acid, the appearance of breakout-prone marks, and uneven-looking tone.
Consider both only if you want separate toner and serum steps. The brand’s stated 1.56-times skin-clarity comparison applies to the pair versus the pad alone, not to a 5%-versus-10% concentration test.
Before purchasing, verify the full ingredient list, review the other active products already in your routine, and account for your own sensitivity. The better choice is not automatically the higher percentage; it is the format and formula that match the routine step you actually need.
