Niacinamide is a versatile, generally gentle active you can use once or twice daily to help with oil control, pores, barrier repair, and uneven tone.

Quick Scoop

  • Apply after cleansing and before moisturizer (and before sunscreen in the morning).
  • Start with low strength (2–5%) once a day, then work up to 5–10% if your skin tolerates it.
  • Most people can use it AM and PM , but sensitive skin may prefer once daily.
  • It layers with vitamin C, retinol, hyaluronic acid, and most other actives if you introduce it slowly.
  • Watch for redness, warmth, or stinging ; if this shows up, cut back the frequency or concentration.

Step‑by‑step: How to Use Niacinamide

  1. Cleanse
    Use a gentle cleanser to remove makeup, oil, and dirt without stripping your skin.
  1. (Optional) Toner
    If you like toner, apply it next to rebalance skin and prep it for actives.
  1. Apply niacinamide
    • Use 1–3 drops of serum or a pea‑sized amount of lotion.
 * Spread over face (and neck, if you like) and let it absorb.
  1. Moisturizer
    Seal everything in with a moisturizer to boost barrier repair and lock in hydration.
  1. Sunscreen (AM only)
    Finish with broad‑spectrum SPF in the morning.

When to Use It (AM, PM, Frequency)

  • Time of day
    • Can be used morning and night ; many derms like it in the AM so you can use retinol at night.
  • How often
    • Most people: start once daily , then increase to twice daily if skin stays calm.
* If you see new redness or warmth, go back down to **once daily**.

How to Combine Niacinamide with Other Actives

  • With vitamin C
    • Apply vitamin C first on clean, dry skin in the morning, then niacinamide, then moisturizer and sunscreen.
  • With retinol
    • A common pattern: niacinamide in the morning, retinol at night.
* Niacinamide can also help **buffer irritation** from retinoids by supporting the barrier.
  • With acids (AHA/BHA, glycolic, etc.)
    • High niacinamide + strong acids can cause temporary flushing in some people, so introduce slowly or alternate days if you’re sensitive.
  • With hydrators
    • Layers well with hyaluronic acid and typical moisturizers and is often paired with glycerin or HA to support dry or reactive skin.

How Strong Should Niacinamide Be?

  • 2–5% : Good for beginners, sensitive skin, or if you’re already using several strong actives.
  • Around 10% : Often used for more visible pores, excess oil, and breakouts, ideally with calming ingredients like glycerin or hyaluronic acid.
  • Using more than 10% too often or stacking multiple high‑niacinamide products can increase the risk of irritation.

Simple Routines (Example)

Beginner / sensitive skin (evening only):

  1. Gentle cleanser
  2. 2–5% niacinamide serum
  3. Moisturizer

Balanced or oily skin (AM & PM):

  • Morning
    1. Cleanser
    2. Vitamin C (optional)
    3. 5–10% niacinamide serum
    4. Moisturizer
    5. Sunscreen
  • Night
    1. Cleanser
    2. Retinol (if you use one)
    3. Niacinamide (if your skin tolerates both the same night, or use it in AM instead)
4. Moisturizer

Safety Tips

  • Patch test new products on a small area for a few days if you’re unsure.
  • Stick to one niacinamide product at a time at first; too many overlapping actives make it hard to know what’s irritating you.
  • If you develop persistent burning, rash, or swelling, stop the product and speak with a dermatologist or health professional.
