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.

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 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 |
|
Niacinamide helps support the skin barrier and reduce dryness and irritation associated with retinol use. |
|
|
The two ingredients target uneven tone and dullness through different pathways and can be used in the same routine. |
|
|
Exfoliating acids help clear dead skin cells, while niacinamide helps regulate oil production and support the skin barrier. |
|
|
Hyaluronic acid attracts moisture to the skin, while niacinamide helps strengthen the barrier to reduce moisture loss. |
|
|
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.
