Choosing a niacinamide serum: how to find the right face serum

A niacinamide serum can be a practical addition to a simple skincare routine. The ingredient appears in formulas for blemish-prone skin, a dull complexion, visible pores and a weakened skin barrier. Yet every serum is different. A high concentration or a long ingredients list alone doesn't tell you much about how well a product will suit your skin.

The following pitfalls are common:

  • A percentage used as a sales gimmick: 10% or 15% niacinamide sounds appealing, but a higher concentration can be less comfortable for some skin types.
  • Too many active ingredients at once: A serum with niacinamide, vitamin C, AHA, salicylic acid or tranexamic acid requires a gentle build-up. Using everything at the same time can unnecessarily stress the skin.
  • Confusing a serum with sun protection: A serum for dark spots does not replace sunscreen. With formulas containing AHA or brightening ingredients, daily UV protection is especially important.

What to look for in a niacinamide serum

1. Concentration and combination of ingredients

Check not only the niacinamide percentage, but also the rest of the formula. A serum with 2% niacinamide can be suitable as a light daily treatment. A formula with 10% or 15% is more targeted, but requires careful use on sensitive skin.

Also look at supporting ingredients:

  • Glycerin, panthenol and hyaluronic acid suit a hydrating serum.
  • Ceramides can fit into a routine for dry or weakened skin barrier.
  • Zinc PCA often appears in formulas for oily or blemish-prone skin.
  • Tranexamic acid or alpha-arbutin is used in serums targeting uneven skin tone and visible dark spots.
  • Vitamin C derivatives appear in formulas for dull skin and a more even complexion.

Please note: claims about visible results are product claims from the brand. Results may be described based on the brand's own research or a test cited by the brand, but they are not automatically the same for every user.

2. Skin type and frequency of use

For a serum for sensitive skin, a short ingredients list, a mild texture and gradual build-up are often practical points to consider. Also check whether fragrance, alcohol denat. or plant extracts are in the formula if you have reacted to them before.

A serum for blemish-prone skin sometimes contains niacinamide combined with zinc PCA or other active ingredients. Dry skin, on the other hand, benefits from a face serum with humectants, followed by a moisturiser.

When trying a new product, start with a small amount. Use it every other day or a few times a week, depending on the product instructions. Stop if you experience persistent redness, itching, swelling or a burning sensation, and if in doubt, seek advice from a doctor or dermatologist.

3. Combining with other serums

Don't automatically use multiple potent products in one routine. A vitamin C serum, tranexamic acid serum, AHA exfoliant or another active product is better applied at a different time. The Ordinary, for example, states that their niacinamide formula should be used alternately with certain vitamin C formulas.

A simple routine looks like this:

  1. Gently cleanse your face.
  2. Apply one serum to a clean, dry skin.
  3. Use a hydrating moisturiser.
  4. During the day, apply a broad-spectrum sunscreen according to the instructions on the packaging.

Frequently asked questions about niacinamide serum

Can I use niacinamide serum every day?

That depends on the concentration, the rest of the formula and your skin's reaction. Some products are intended for daily use in the morning and evening. With a stronger formula or sensitive skin, it's wiser to start with a few applications per week. Always follow the instructions on the packaging.

Is niacinamide suitable for sensitive skin?

Niacinamide can appear in a serum for sensitive skin, but the overall formula determines its suitability. Check for fragrance, alcohol, acids and other active ingredients. When trying a new product, do a patch test first and don't combine multiple intensive serums straight away.

How long does a bottle of face serum last?

A 30 ml bottle usually lasts longer with daily use than if you apply it generously over your face, neck and other areas. Typically use just a few drops, close the packaging properly and store the serum according to the instructions. Check the expiry date and the period after opening on the packaging.
