Nicotinamide (Niacinamide) – Benefits, Side Effects & Uses

Niacinamide (also called Nicotinamide) is a form of vitamin B3 that has become one of the most trusted ingredients in skincare. Dermatologists recommend it for its gentle yet powerful effects on improving skin barrier function, evening skin tone, and reducing irritation.

What is Niacinamide?

Niacinamide is a water-soluble vitamin that works with your skin's natural biology. It helps build keratin (a key protein for strong, healthy skin), strengthens the skin barrier, and regulates sebum production. It is suitable for almost all skin types — including sensitive and acne-prone skin — making it a versatile addition to most routines.

Key Benefits

Strengthens the skin barrier: Reduces transepidermal water loss, keeping skin hydrated and plump.
Minimises pores: Helps regulate oil production and makes pores appear smaller over time.
Reduces hyperpigmentation: Inhibits melanosome transfer, leading to a brighter, more even complexion.
Soothes redness: Calms irritation and reduces visible signs of inflammation.
Anti-aging support: Stimulates ceramide production, softening fine lines.
Balances oily skin: Regulates excess sebum without over-drying.

Who Should Use It?

Anyone with uneven skin tone or dark spots
Those with oily or acne-prone skin
People with redness or sensitivity
Anyone looking to strengthen their skin barrier

Who Should Avoid It?

Most people can tolerate Niacinamide well, but those with known allergies or reactions to vitamin B3 should avoid it.
If irritation occurs, try a lower concentration (2-5%) or use every other day.

How to Use Niacinamide in Your Routine

Apply after cleansing and toning but before heavy creams or oils.
Works well with most actives, including hyaluronic acid and peptides.
Avoid combining with very low pH formulas (like strong vitamin C serums) in the same routine to prevent flushing.
Daily SPF is recommended to protect results.

Verdict

Niacinamide is one of the most beginner-friendly, research-backed ingredients in skincare. It delivers visible results for brightness, clarity, and overall skin health with minimal risk of irritation.

FAQs

Can Niacinamide cause purging?
No — Niacinamide is not an exfoliant, so it does not trigger purging. Breakouts may be due to another ingredient in your routine.

Is Niacinamide safe during pregnancy?
Yes, topical Niacinamide is generally considered safe, but always consult your doctor if unsure.

What concentration should I use?
Most studies show 2–5% delivers benefits with minimal irritation. Higher concentrations (10%) can be effective for stubborn concerns but may cause flushing in very sensitive skin.
