Niacinamide 101: The Multitasking Ingredient Your Routine Needs

If there's one ingredient that genuinely does it all, it's niacinamide. Also known as Vitamin B3, this water-soluble vitamin is one of the most researched and dermatologist-recommended actives in skincare—and for good reason.

What Niacinamide Actually Does

Niacinamide is a true multitasker. Here's what the clinical evidence supports:

Oil and Pore Control

Niacinamide regulates sebum production, reducing excess oil without stripping the skin. Studies show consistent use visibly minimises pore size and improves overall texture—particularly for oily and combination skin.

Pigmentation and Tone

It inhibits melanin transfer, meaning it helps fade dark spots, post-acne marks, and uneven tone over time. It's gentler than harsh brightening agents, making it suitable for sensitive skin.

Barrier Support

Niacinamide stimulates ceramide production, strengthening your skin barrier and reducing trans-epidermal water loss. This means better hydration and less sensitivity.

Redness and Inflammation

Its anti-inflammatory properties make it ideal for rosacea-prone and reactive skin. It calms redness and soothes irritation without clogging pores.

What Concentration Works Best?

A common myth is that more is better. Research shows that 2–5% niacinamide delivers optimal results—concentrations above 10% offer no additional benefit and may actually cause irritation.

How to Use It

Niacinamide is one of the most forgiving actives in skincare. It plays well with retinol, Vitamin C, acids, and peptides. Apply it morning and/or evening after cleansing and before heavier creams. It's the ultimate team player in any routine.

Who Benefits Most?

• Oily and acne-prone skin (oil and pore control)

• Hyperpigmentation concerns (gentle brightening)

• Sensitive or rosacea-prone skin (anti-inflammatory)

• Ageing skin (barrier support and collagen stimulation)
