You’ve probably heard a lot about niacinamide. But is it really that great? And is it safe for your skin?
Niacinamide (also called vitamin B3) is now a favorite in skincare. It helps make your skin brighter, controls oil, makes your skin barrier stronger, and calms redness. But just like any skincare ingredient, there’s a lot of mixed info out there—and niacinamide may not work the same way for everyone.
In this blog, we’ll share the real facts about niacinamide, what side effects to watch out for, and how to know if it’s right for you.
Possible Side Effects of Niacinamide
Most people can use niacinamide with no problems—even if they have sensitive skin. But sometimes, side effects can show up when you first start using it or if you're using too much.
1. Redness or Irritation
Some people notice a little stinging, redness, or irritation. This usually goes away quickly. But if your skin is very sensitive or damaged, the irritation can last longer.
2. Flushing (Red, Warm Skin)
Using high amounts of niacinamide (more than 5%) can sometimes cause your face to feel hot, look red, or tingle. It’s not harmful, just uncomfortable.
3. Breakouts: Is It Purging or a Bad Reaction?
Although this is rare with niacinamide, some people get pimples when they start using it. This is called “purging” and may happen because niacinamide speeds up how fast your skin renews. It usually clears up in a few weeks. But if the breakouts keep getting worse, your product might be too strong or not working well with the rest of your routine.
Why These Side Effects Happen
1. Overusing
Niacinamide works great—but using it in too many products (cleanser, toner, serum, moisturizer) at once can overload your skin.
2. Too Strong
Most skin types do well with 2% to 5% niacinamide. The majority of studies have been conducted on 2-5% concentrations of niacinamide. More than that is not needed.If you’re using more than 5%, it’s more likely to cause redness or breakouts—especially if your skin is sensitive.
3. Individual Differences
Everyone’s skin is different so what works for one person may not work for another. Keep that in mind when trying out all products, including those with niacinamide.
Side note: if you have sensitive skin you should patch test the product first.
Niacinamide Myths or Facts
Myth 1: Niacinamide Cannot be Used with Vitamin C
False. This is old news. It used to be true when vitamin C formulas weren’t stable. But now, many modern products can safely mix niacinamide and vitamin C.
Myth 2: Niacinamide Makes Your Skin Peel
Nope! Niacinamide does not exfoliate your skin. If your skin is peeling, it’s probably from another ingredient like retinol or an acid—or just using too many actives at once.
Myth 3: You Don’t Require Sunscreen If You Use Niacinamide
Not true. Niacinamide helps protect your skin, but it doesn’t replace sunscreen. In fact, using both together gives your skin better protection against sun damage and pollution.
Here are some more myths.
