What Is Niacinamide For Skin? A Complete Guide To Vitamin B3

Share this:

Skin is the body’s largest organ, and when it is healthy, it functions as a protective barrier against bacteria, fungi, toxins, and other environmental elements. Skin cells are constantly regenerating to create new skin layers.

However, with age, our skin can become thinner and less able to ward off environmental aggressors. This can lead to dryness, dullness, dehydration, dark spots, wrinkles, acne, or other forms of damage.

That’s where niacinamide comes into play. Niacinamide is a form of Vitamin B3, an antioxidant that protects the skin from harmful substances without being too harsh on the skin.

Read on to learn more about niacinamide and how you can incorporate this important vitamin into your skincare routine.

What is niacinamide?

Niacinamide is a form of B3 that is water-soluble and found in many foods, such as meat, vegetables, and fish. It can also be taken as a supplement or applied topically on the skin to reduce the appearance of fine lines and wrinkles.

When applied topically, niacinamide can be used as an alternative to other anti-aging products like Retin A and Tazorac because it doesn’t cause redness or peeling.

Niacinamide is also used for treating acne because studies have shown it to decrease oil production, decrease the severity of acne, and reduce pore size and inflammation.

The goal of using niacinamide is not just reduction of blemishes, but preventing future breakouts as well. In addition to these benefits, this vitamin also helps to even out skin tone by fading dark spots and hyperpigmentation.

How does niacinamide work to reduce wrinkles?

“Niacinamide works to reduce the appearance of wrinkles on the skin by inhibiting the activity of enzymes that break down DNA and collagen,” says Dr. Brandith Irwin, a Seattle-based board-certified dermatologist.

When niacinamide is present in your skin, it prevents your skin from breaking down collagen. This process aids in reducing aging signs like wrinkles and fine lines because your skin will produce more collagen.

Studies also show that applying niacinamide topically may increase ceramide synthesis in the outer layer of the skin. This ceramide forms a barrier on the surface of the skin that helps to prevent moisture loss.

Furthermore, niacinamide can help reduce skin hyperpigmentation by preventing melanin from reaching the surface of the skin. It also has antioxidant properties that protect against damage by harmful molecules called free radicals.

Is niacinamide good for oily skin?

The major cause of oily skin is the excessive production of sebum in the skin. Sebum is an oily secretion produced by the sebaceous glands in your skin.

It is important for your skin because it helps to moisturize and protect it from damage.

However, an overproduction of sebum can cause oily skin, which in turn leads to blemishes and acne. Niacinamide helps to reduce the amount of sebum in your skin, and lessens shine, thereby reducing the appearance of oily skin.

“It does this by increasing the turnover rate of your skin cells to stimulate natural oil-reducing processes already occurring within the outermost layer of your skin,” Dr. Irwin explains.

Using niacinamide to control oil production can help reduce acne breakouts and blackheads. It can also help balance your skin’s natural moisture barrier by strengthening cell membranes.

Is niacinamide good for dry skin?

Niacinamide is rapidly and well absorbed through the skin and has been shown to be effective at reducing dryness and roughness in as little as two weeks.

“The exact mechanism of action for this effect is unknown, but it appears that niacinamide works by reducing barrier dysfunction in the skin,” Dr. Rachel Nazarian MD, FAAD board-certified dermatologist, explains.

According to her, niacinamide works to reduce dry skin by increasing the amount of water content in the outer layer of the skin. It effectively does this by inhibiting enzymes involved in breaking down the skin barrier.

In addition, niacinamide is a powerful antioxidant that helps slow down the breakdown of collagen and elastin. These two structural proteins, when broken down, cause the skin to lose its elasticity and become rough and flaky.

Is niacinamide good for acne?

Niacinamide is one of the most reliable and effective ingredients for acne. It also treats rosacea, and hyperpigmentation, while also helping with sun damage. It does all this by regulating how your body produces oil and preventing melanin production.

Clinical studies have shown niacinamide to be as effective as benzoyl peroxide, but without the drying side effects,” Nazarian explains.

Another way niacinamide works to treat acne is by slowing down the growth of the bacteria that causes acne to form. It’s also an anti-inflammatory agent, which can reduce redness and irritations associated with acne.

Finally, it helps with the production of lipids in your skin, which can help to improve your skin texture, making it look smoother and more even.

Does niacinamide lighten skin?

Niacinamide is an effective skin-lightening ingredient used for treating different types of hyperpigmentation. Hyperpigmentation, which can make your skin look less even, is usually caused by hormones, genetics, sun exposure, or pregnancy.

“Niacinamide helps to treat this condition by decreasing the amount of melanin produced in skin cells. It can also help protect the skin against sun damage,” Irwin says.

Niacinamide is also known to work with prescription hydroquinone to lighten skin more effectively. However, this combination should only be used under the supervision of a dermatologist because it comes with some risks.

Niacinamide side effects

Niacinamide is safe for all skin types, including those with sensitive skin. It may even be better tolerated than traditional topical treatments because it isn’t as irritating to the skin.

However, some people experience side effects when taking niacinamide. This may be due to an existing medical condition or it can be related to the dosage.

If you are experiencing any unusual symptoms while taking niacinamide, talk to your doctor right away.

Benefits of using niacinamide on skin

Niacinamide is a form of vitamin B3, which has been found to improve skin health in a remarkable number of ways. When applied topically, niacinamide:

  • Treats dark spots, sun spots, and other kinds of hyperpigmentation. It helps by reducing the amount of melanin in skin cells.
  • Restores lost moisture in the skin. It helps by increasing the amount of water in skin cells and preventing moisture loss.
  • Relieves skin conditions such as rosacea and psoriasis. It does this by reducing the redness and inflammation associated with these conditions.
  • Eliminates acne by fighting acne-causing bacteria, and reducing the production of skin oil (sebum).
  • Reduces the appearance of wrinkles, fine lines, and other aging signs. It does this by increasing the synthesis of collagen, which supports the skin’s elasticity.
  • Increases ceramide levels in the skin. This prevents it from drying out and resulting in eczema and other dry skin conditions.
  • Reduces oily skin. It helps by shrinking pores, increasing the turnover rate of skin cells, and improving sebum excretion.
  • Prevents premature aging. It does this by protecting your skin from damage caused by free radicals and sun damage.
  • Improves overall skin texture and tone. It does this by stimulating the production of collagen and inhibiting melanin production in skin cells.

How to use niacinamide in your skincare routine

The best way to use niacinamide in your skincare routine is by applying a niacinamide product just after cleansing but before applying any other skincare products like moisturizer or sunscreen.

How to use niacinamide:

  • Ensure that your skin is clean and free from makeup. You can do this with a gentle cleanser and toner before you apply the niacinamide.
  • Apply a small amount of niacinamide cream or serum to your fingertips or palms and gently rub it into your skin in circular motions, avoiding the eye area.
  • Ensure to wash your hands after applying the niacinamide to avoid getting it on unwanted surfaces (this should not take more than 10 seconds).
  • Apply moisturizer for hydration or sunscreen for protection if required.
  • Finish up by applying makeup if desired.

Other things to note:

  • Do not use too much of this product- experts recommend using about 1-2 pumps per application.
  • Avoid applying a niacinamide product near your eyes or mouth.
  • Leave it on your skin for at least 10 minutes before applying moisturizer.
  • Ensure to do a patch test before using a niacinamide cream, serum, or powder to see if you have any irritations or allergies to the product.
