Niacinamide

Enlarged pores. Persistent oiliness. Post-blemish marks that will not fade. Uneven tone that no moisturizer seems to improve. These are among the most common skin concerns in Singapore — and niacinamide addresses all of them.

Also known as vitamin B3, niacinamide is a water-soluble, stable, and exceptionally well-tolerated active. 

Unlike most skincare actives that target one concern at a time, niacinamide works across multiple visible problems simultaneously — which is why it suits every skin type and fits into any routine.

Paula's Choice niacinamide products are fragrance-free, clinically tested to be non-irritating, and available from 5% to 20% concentration across dedicated treatments, serums, toners, moisturizers, SPF, and body formulas.

What Niacinamide Does

Niacinamide works across multiple visible concerns through different mechanisms — often in the same formula.

  • Regulates sebum production.

    Niacinamide reduces oiliness at the source rather than stripping oil from the surface. This matters because harsh oil-control products often trigger compensatory oiliness — the skin overproduces sebum to replace what has been removed. Niacinamide breaks that cycle.

  • Minimizes the appearance of enlarged pores. 

    Pores appear enlarged when excess sebum stretches the pore lining outward, or when surrounding skin loses elasticity with age. Niacinamide reduces sebum pressure on the pore walls and supports skin elasticity — both contributing to visibly smaller-looking pores over time.

  • Fades dark spots and post-blemish marks. 

    Niacinamide inhibits the transfer of melanin to skin cells, which is the step that makes pigmentation visible. This fades existing marks and slows the formation of new ones — effective for both UV-related discoloration and the post-inflammatory marks left by breakouts.

  • Strengthens the skin barrier.

    Niacinamide supports the skin's lipid barrier, improving moisture retention and resilience — particularly useful for skin that loses hydration in air-conditioned environments or reacts to other active ingredients.

  • Visibly calms redness.

    Niacinamide reduces visible inflammation and is well tolerated by sensitive, rosacea-prone, and reactive skin.

  • Improves skin elasticity and the appearance of fine lines. 

    With consistent use at 10% and above, niacinamide supports firmness and reduces the look of fine lines.

    Most actives address one of these concerns. Niacinamide addresses all of them at 5% and above, for all skin types, in any routine position.

Skin that is already used to niacinamide — not for beginners

Why Most People Should Start With 10% Niacinamide

5% Niacinamide

  • Works well as a supporting concentration in toners and moisturizers.

  • Helps improve skin tone, regulate excess oil, and strengthen the skin barrier.

  • Effective when combined with other active ingredients.

  • May not deliver significant pore-refining or pigmentation improvements when used as the primary treatment.

10% Niacinamide

  • The concentration most people should start with for targeted results.

  • Acts as a primary treatment rather than a supporting ingredient.

  • More effectively helps normalize sebum production and reduce the appearance of enlarged pores.

  • Supports visible improvement in uneven skin tone and post-blemish marks.

  • Aligns with concentrations commonly used in clinical studies evaluating niacinamide's effectiveness.

20% Niacinamide

  • Intended for more advanced or resistant concerns.

  • May be appropriate for significantly enlarged pores, rough orange-peel texture, or stubborn discoloration.

  • Not necessarily a better starting point than 10%.

  • Higher concentrations can increase the likelihood of temporary flushing or irritation in first-time users.

Recommended Approach

  • Start with 10% niacinamide and use it consistently for at least eight weeks.

  • Assess improvements in pores, oiliness, and pigmentation.

  • Consider moving to 20% only if additional improvement is needed and your skin has tolerated 10% well.

Why 10% Niacinamide Booster Is Our Bestselling Niacinamide

The 10% Niacinamide Booster combines a clinically effective concentration of niacinamide with soothing and hydrating ingredients in an ultra-light formula that can be used alone or mixed into your existing serum or moisturizer.

While many niacinamide products focus on a single concern, the 10% Niacinamide Booster helps improve:

  • Enlarged pores

  • Excess oil

  • Uneven skin tone

  • Post-blemish marks

  • Dullness

  • Redness

  • Dryness caused by a weakened barrier

  • Fine lines and loss of radiance

For most people, it is the simplest and most effective way to experience the full benefits of niacinamide.

How Niacinamide Improves Common Skin Concerns

Concern

How Niacinamide Helps

Enlarged Pores

Oily Skin

Helps normalize oil production to reduce shine and minimize congestion.

Post-Blemish Marks and Dark Spots

Helps reduce the transfer of excess pigment within the skin, supporting a more even-looking skin tone.

Sensitive and Barrier-Compromised Skin

Helps calm visible redness, strengthen the skin barrier, and improve skin resilience.

Aging Skin

Helps improve elasticity, enhance radiance, and soften the appearance of fine lines.

When Will You See Results?

Niacinamide works gradually, and consistent use is key to seeing visible improvements.

Why Niacinamide Works Well in Singapore

  • Humidity drives oiliness. 

    Singapore's heat increases sebum production throughout the day. Niacinamide normalizes oil output at the source — a more sustainable solution than harsh oil-control products that trigger compensatory oiliness.

  • Post-blemish marks are harder to avoid.

    Breakouts are more frequent in humid conditions, and the post-inflammatory hyperpigmentation they leave is particularly pronounced in deeper skin tones. Niacinamide fades existing marks and helps minimize the formation of new marks.

  • Air-conditioning stresses the barrier. 

    The daily transition between outdoor humidity and cool indoor environments draws moisture from the skin. Niacinamide strengthens the lipid barrier, helping the skin retain hydration across these repeated shifts.

What Pairs Well With Niacinamide?

One of niacinamide's biggest advantages is its compatibility with other skincare active ingredients. It can be used alongside most ingredients without increasing irritation.

Ingredient

Why They Work Well Together

Retinol

Niacinamide helps support the skin barrier and reduce dryness and irritation associated with retinol use.

Vitamin C

The two ingredients target uneven tone and dullness through different pathways and can be used in the same routine.

BHA or AHA

Exfoliating acids help clear dead skin cells, while niacinamide helps regulate oil production and support the skin barrier.

Hyaluronic Acid

Hyaluronic acid attracts moisture to the skin, while niacinamide helps strengthen the barrier to reduce moisture loss.

Peptides

Peptides support firmness and elasticity, while niacinamide helps improve tone, pores, and oil balance.

How To Use Niacinamide

When in the skincare routine: Apply after cleansing and any leave-on exfoliant, and before moisturizer. 

The order is: cleanser → toner → exfoliant → niacinamide serum or booster → moisturizer → sunscreen/ SPF (during the day)

How often: Twice daily — morning and evening. Niacinamide is stable in sunlight and does not require morning avoidance.

How to apply the booster: Dispense two to three drops into the palm and press gently into the face and neck. Use alone or blend into your serum or moisturizer.

Niacinamide does not increase photosensitivity and can be used safely in the morning. For daytime use in Singapore's high-UV environment, always finish your morning routine with a broad-spectrum sunscreen rated SPF 30 or greater. Browse the Paula's Choice sunscreen collection.

Frequently Asked Questions About Niacinamide in Singapore

What does niacinamide do for your face?

Visibly minimizes enlarged pores, regulates sebum, improves uneven tone, fades dark spots and post-blemish marks, reduces visible redness, supports the skin barrier, and improves the appearance of fine lines. It addresses multiple concerns simultaneously and suits all skin types.

Is it okay to use niacinamide every day?

Yes — twice daily, from day one. Niacinamide is non-photosensitizing, stable, and among the most well-tolerated skincare actives available. One exception: start the 20% Treatment once daily in the evening and assess tolerance before increasing frequency.

How long does niacinamide take to work?

Oiliness and barrier support improve within 2 to 4 weeks. Visible pore improvement develops over 4 to 8 weeks. Post-blemish marks and uneven tone typically take 8 to 12 weeks of consistent use.

Does niacinamide remove dark spots?

It fades existing marks and helps prevent new discoloration from forming by inhibiting melanin transfer to skin cells. Results take 8 to 12 weeks of consistent daily use.

What cannot be mixed with niacinamide?

Niacinamide is compatible with retinol, vitamin C, AHA, BHA, hyaluronic acid, peptides, and ceramides. The concern that niacinamide and vitamin C conflict is based on outdated research — modern stabilized formulas are not affected.

Is niacinamide good for aging skin?

Yes. Niacinamide improves skin elasticity, visibly reduces fine lines, supports the barrier, and improves uneven tone. Used alongside retinol, it addresses aging more comprehensively than either ingredient alone.

Which is better — retinol or niacinamide for aging skin?

They work better together. Retinol promotes cell turnover and collagen production. Niacinamide improves tone and elasticity — and helps buffer the irritation retinol can cause during adjustment.

How to apply niacinamide correctly?

After cleansing and any leave-on exfoliant. Before applying moisturizer. Press gently into the face and neck. Two to three drops are sufficient for a booster.

Can I blend the niacinamide booster into my moisturizer?

Yes. The 10% Niacinamide Booster is designed to be blended into a serum or moisturizer as an alternative to standalone application.

How to tell if niacinamide is working?

Look for gradual reduction in enlarged pores, more even skin tone, reduced surface oiliness, and fading of post-blemish marks. Comparing at four and eight weeks is more useful than a day-to-day assessment.

Are Paula's Choice niacinamide products suitable for sensitive skin?

Yes. All formulas are fragrance-free and clinically tested to be non-irritating. Begin with the 10% Niacinamide Booster once daily if skin is very reactive, and increase gradually.
