Niacinamide: benefits, how to use it, and what to combine it with
One of the most studied and versatile active ingredients. What it does, what concentration to choose, and how to include it in your routine.
Niacinamide is one of the best-known and most widely used active ingredients in skincare, and for good reason: it is versatile, generally well-tolerated, and has more scientific backing than many trends. This is the guide to using it correctly.
What is niacinamide
It is a form of vitamin B3. It is water-soluble, stable, and suitable for use day and night. It appears in many products: serums, creams, toners, and even sunscreens.
What it is for
Depending on the formula and concentration, niacinamide can help to:
Improve the appearance of enlarged pores and regulate the appearance of shine in oily or combination skin.
Even out skin tone and fade the appearance of dark spots, in conjunction with daily sun protection.
Support the skin barrier, which translates into more comfortable skin.
Calm the appearance of redness in reactive skin.
It is not a miracle product nor does it replace treatment indicated by a dermatologist, but it is an excellent daily support.
What concentration to choose
Standard concentrations in cosmetics range from 2% to 10%, and a large portion of studies use between 2% and 5%. More is not always better: high concentrations can cause redness or itching in some people. If your product is highly concentrated, start two or three times a week and increase gradually.
For example, The Niacinamide 15 Serum by COSRX is a concentrated formula (15%, according to the brand). If your skin is sensitive or you have never used niacinamide, introduce it gradually.
How to use it step by step
After cleansing and, if you use one, toner or essence.
Apply a few drops or the amount indicated by the brand over your entire face.
It can help regulate the appearance of oil and inflammation in acne-prone skin as a complement. It does not replace treatment indicated by a professional.
Can it be used during the day?
Yes. It is not photosensitizing. Even so, use sunscreen every day.
How long does it take to see results?
Changes in tone and texture are usually evaluated after 4 to 8 weeks of consistent use.
Is it safe for sensitive skin?
It is usually well-tolerated, but at high concentrations it can be irritating. Start with low frequency and do a patch test.
