Niacinamide Guide – How It Works & How to Use It

Niacinamide (vitamin B3) has become a staple ingredient in modern skincare for a reason. It touches several key processes in the skin at once – oil production, barrier strength, redness and uneven tone.

What Niacinamide Actually Does

• Regulates sebum: can gradually reduce excessive oiliness.
• Supports the barrier: helps increase ceramide and fatty acid levels.
• Calms redness: has documented anti-inflammatory effects.
• Improves tone: can help fade certain types of hyperpigmentation.

Choosing the Right Percentage

• 2–5%: gentle, good for sensitive or rosacea-prone skin.
• 5–10%: common “sweet spot” for most people.
• 15–20%: booster territory; often better as an occasional, targeted step.

Where Niacinamide Fits in Your Routine

1. Cleanse with a mild, low-foam cleanser.
2. Optional mist or hydrating toner.
3. Niacinamide serum or lotion.
4. Moisturiser if needed.
5. SPF 30+ every morning.

Already overwhelmed by actives? You may not need another separate serum – a moisturiser containing niacinamide can be enough.

Good Niacinamide “Neighbours”

• Gentle hydrating toners and serums.
• Ceramide-rich moisturisers.
• Daily sunscreen.
• Retinoids and acids, when used sensibly in the same routine.

Niacinamide is flexible – it works in both morning and evening routines. Choose the slot that feels easiest to stick with consistently.
