Niacinamide is a popular skincare ingredient used to support clearer, brighter and more balanced-looking skin. It can help manage excess oil, improve the appearance of enlarged pores and post-blemish marks, and strengthen the skin barrier. This guide explains who niacinamide is best for, which percentage to choose, how to use it and what ingredients to pair it with.
What Is Niacinamide And What Does It Do?
Niacinamide, also known as nicotinamide, is a water-soluble form of vitamin B3 used in skincare to support moisture retention, sebum regulation and overall skin resilience.
It can be found in serums, toners, cleansers, moisturisers and SPF formulas. Generally well tolerated, it is suitable for a wide range of skin types and routines.
What Are The Benefits Of Niacinamide For Skin?
Used consistently, niacinamide can:
-
Support the skin barrier by encouraging ceramide production and reducing transepidermal water loss.
-
Balance excess sebum and shine, making it useful for oily and combination skin.
-
Make enlarged pores appear less noticeable by regulating oil and smoothing texture.
-
Improve the appearance of blemishes, post-blemish marks and post-inflammatory hyperpigmentation.
-
Brighten dull, uneven skin tone and reduce the appearance of dark spots.
-
Calm visible redness and promote smoother, healthier-looking skin.
Is Niacinamide Good For Every Skin Type?
Niacinamide suits most skin types, although the best formula and concentration depend on individual tolerance.
-
Oily skin: Helps reduce shine and make enlarged pores appear less noticeable.
-
Acne-prone skin: Regulates oil and improves post-blemish marks, but is not a complete acne treatment.
-
Dry or dehydrated skin: Supports ceramide production and moisture retention. The Beauty Of Joseon Renew Dynasty Cream combines niacinamide and squalane to help balance oil and moisture.
-
Sensitive skin: Lower concentrations and simple formulations are usually the best place to start.
-
Combination skin: Balances oilier areas without stripping drier areas.
What Percentage Of Niacinamide Should You Use?
The best niacinamide percentage depends on your skin type, experience and the concern you want to target. Lower concentrations can still deliver visible benefits, while stronger formulas may increase the risk of irritation.
When comparing 5% vs 10% niacinamide, formula quality, supporting ingredients and consistent use matter more than choosing the highest concentration.
Best Niacinamide Serums For Different Skin Concerns
The best niacinamide serum depends on your skin type, preferred concentration and main concern. Consider the supporting ingredients in the formula rather than focusing on percentage alone.

How To Use Niacinamide In Your Skincare Routine
A niacinamide routine does not need to be complicated. Choose one suitable product alongside gentle cleansing, hydration and daily sun protection.
Morning Routine
-
Cleanse to refresh the skin and remove excess oil. For oily or blemish-prone skin, try the CeraVe Blemish Control Cleanser, formulated with niacinamide, salicylic acid and ceramides.
-
Use a toner or essence to hydrate and prepare the skin. The Beauty Of Joseon Ginseng Essence Water contains 2% niacinamide alongside ginseng water to support moisture and oil balance.
-
Apply a niacinamide serum to target concerns such as excess oil, enlarged pores, dark spots or uneven tone.
-
Moisturise to lock in hydration.
-
Finish with broad-spectrum SPF to protect the skin and help prevent pigmentation from becoming more noticeable.
Evening Routine
-
Cleanse to remove makeup, SPF and daily build-up.
-
Apply a treatment or serum suited to your main skin concern.
-
Moisturise to support the skin barrier and maintain hydration overnight. Try the Medicube Collagen Jelly Cream, a bestselling jelly moisturiser combining niacinamide, hydrolysed collagen, hyaluronic acid and squalane for brighter, plumper and more hydrated-looking skin.
-
Use a mask once or twice a week for additional hydration and radiance. The Biodance Radiant Vita Niacinamide Real Deep Mask combines niacinamide with glutathione, pineapple water and hyaluronic acid.
Remember: Niacinamide may already be present in your cleanser, toner or moisturiser, so a separate serum is not always necessary.
Niacinamide For Beginners: How Often Should You Use It?
If you are new to niacinamide, start with one product once daily or several times a week. Increase gradually if your skin remains comfortable, particularly when using a higher concentration.
Check whether niacinamide already appears elsewhere in your routine and avoid introducing several new active ingredients at once.
What Can You Use With Niacinamide?
Niacinamide pairs well with many popular skincare ingredients, making it easy to target hydration, blemishes, uneven tone and barrier support.
Niacinamide and hyaluronic acid work together to support hydration and moisture retention.
Vitamin C and niacinamide can be used together to brighten uneven tone and provide antioxidant support. Sensitive skin may prefer using them at different times of day.
Niacinamide supports the skin barrier while retinol targets texture, blemishes and fine lines. Introduce retinol gradually.
This pairing suits oily, congested and blemish-prone skin. Salicylic acid helps clear pores, while niacinamide balances oil.
Niacinamide and azelaic acid can improve the appearance of redness, blemishes, dark spots and uneven tone.
Tranexamic acid and niacinamide work together to target dark spots, post-blemish marks and uneven tone. The Medicube TXA Niacinamide Capsule Cream combines both with ceramides and hyaluronic acid.
Glutathione and niacinamide offer complementary brightening and antioxidant benefits. The Medicube Glutathione Glow Serum combines both ingredients to improve dullness, pigmentation and uneven tone.
Ceramides support the skin barrier, peptides promote smoother-looking skin and daily SPF helps protect against UV damage and worsening pigmentation.
What Should You Avoid Using With Niacinamide?
Niacinamide is compatible with most common skincare ingredients, so there are few combinations that must always be avoided. Irritation is more likely when several high-strength formulas are layered at once, such as concentrated acids, retinoids and a strong niacinamide serum.
Individual tolerance and overall formula strength matter more than strict pairing rules. If your skin feels sensitive, alternate stronger actives or separate them between morning and evening.
Does Niacinamide Cause Purging Or Irritation?
Niacinamide does not usually cause purging because it does not exfoliate the skin like retinoids or acids. New breakouts may instead be linked to irritation, a high concentration or another ingredient in the formula.
Signs of irritation can include redness, itching, stinging or dryness. Patch test new formulas and stop using the product if discomfort continues.
How Long Does Niacinamide Take To Work?
Some people may notice improved hydration and skin comfort relatively quickly, while changes to excess oil, texture, dark spots and post-blemish marks usually require several weeks of consistent use.
Results vary depending on the concentration, formula, wider routine and concern being targeted. Use broad-spectrum SPF every morning when addressing pigmentation or uneven skin tone.
Niacinamide FAQs
Niacinamide Vs Hyaluronic Acid: Which Is Better?
Niacinamide helps balance oil, support the skin barrier and improve uneven tone, while hyaluronic acid mainly targets dehydration. Neither is better overall, and they can be used together if your skin needs both hydration and oil or tone support.
Niacinamide Vs Vitamin C: Which Is Better?
Niacinamide is particularly useful for oil balance, enlarged pores and barrier support, while vitamin C focuses more on antioxidant protection, radiance and uneven tone. Neither is better overall, and both can be used in the same routine if your skin tolerates them.
Does Niacinamide Help With Acne?
Niacinamide can balance excess oil, calm redness and improve post-blemish marks, but it is not a complete acne treatment.
Does Niacinamide Help With Dark Spots?
Consistent use can improve dark spots, post-blemish marks and uneven tone. Always wear SPF when targeting pigmentation.
Does Niacinamide Reduce Pores?
Niacinamide cannot physically shrink pores, but it may make them appear less noticeable by balancing oil and smoothing texture.
Does Niacinamide Help With Fine Lines?
Niacinamide may help soften the appearance of fine lines by supporting moisture retention, the skin barrier and smoother-looking texture. Results vary depending on the formula and require consistent use.
Is 10% Niacinamide Too Strong?
A 10% formula may suit oily or resilient skin, but lower concentrations can still be effective and gentler.
