Top 10 Niacinamide Benefits for the Skin

Learn about niacinamide and why it’s considered a superstar skincare ingredient that can treat almost every skin concern.

Niacinamide is a superstar ingredient that deserves some recognition. It is right up there on the list next to other outstanding skincare ingredients such as retinol, hyaluronic acid, and vitamin c.

Niacinamide is an ingredient that promises to control skin troubles and help get skin health on track. Almost any and all of your skin concerns can be addressed by niacinamide, making it a phenomenal multitasking skincare ingredient.



Niacinamide is a form of vitamin B3, one of the eight essential nutrients in Vitamin B Complex, which is vital for maintaining your metabolism and a healthy nervous system.


Niacinamide vs. Niacin

Niacinamide is also known as nicotinamide, the active and water-soluble form of Vitamin B3. Nicotinic Acid, also known as niacin, is the other form of vitamin B3.

Niacin is converted to niacinamide when there is an excess amount of niacin than what the body needs.

Niacinamide is preferred over niacin because it does not cause skin flushing, a condition wherein the blood vessels expand, causing redness, itchiness, and a tingling sensation.


Sources of Niacinamide

Daily intake of vitamin B3 from natural food sources, dietary supplements, and topical use is essential for skin health since it is not naturally stored in the body.

You can get vitamin B3 from a balanced and healthy diet that includes eggs, milk, cereals, green veggies, nuts, seeds, and beans.

Various plant and animal products as well as some food supplements contain niacinamide. It is also a potent ingredient found in different skincare products used to treat acne or rosacea.




Niacinamide is synthesized when we consume food that is high in niacin. Our intestinal bacteria converts niacin into the active form niacinamide, which is a precursor to the coenzymes nicotinamide adenine dinucleotide (NADH) and nicotinamide adenine dinucleotide phosphate (NADPH).

NADH and NADPH are essential factors in our physiological processes such as cellular metabolism, calcium regulation, oxidation, gene expression, immune functions, the aging process, and cell turnover.

The skin quickly absorbs niacinamide. To maximize its benefits for skin health, niacinamide can be used topically.

When applied topically, niacinamide boosts cell energy, which stimulates cell turnover and microcirculation. It acts as an antioxidant that protects the skin from free radicals. It reinforces the lipid barrier to hold moisture in and prevents irritants from penetrating the skin. It is antibacterial, regulates sebum production, and calms irritation.


Depending on its concentration, niacinamide has the following properties:

  • Antipruritic
  • Antimicrobial
  • Vasoactive
  • Photo-protective
  • Sebostatic effect
  • Lightening effect




Niacinamide is an excellent choice for those who are not really into oily serums. Niacinamide is found in water-based serums. Unlike retinoids, light, oxidation, and damp surroundings do not affect the stability of niacinamide.

Niacinamide has a PH which is almost neutral. Unlike alpha and beta hydroxy acids, it is non-acidic and non-irritating, making it perfect for treating various skin concerns regardless of skin type.



Here are the 10 fantastic ways that niacinamide can improve your complexion.



Niacinamide can dramatically diminish the look of fine lines and wrinkles with continuous use. In a clinical study conducted over the span of 12 weeks, topical 5% niacinamide demonstrated a 21% improvement in fine lines.

Other studies suggest that niacinamide increases dermal collagen production. An increase in collagen production benefits the skin by strengthening the skin and improving its elasticity and hydration. Even better, an increase in collagen production helps to minimize fine lines and wrinkles. 


Niacinamide is an excellent treatment for acne due to its antimicrobial and anti-inflammatory properties.

In a study, 4% nicotinamide gel was observed to be effective in treating moderate acne. The success of the acne treatment is due to the anti-inflammatory properties of niacinamide.

Compared to other acne treatments such as retinoids and benzoyl peroxide, niacinamide is much gentler on the skin. It also helps to lighten dark spots and scars caused by acne.




The amount of oil the sebaceous glands produce is controlled when the skin is adequately moisturized. With the continued use of niacinamide, you may experience fewer breakouts and improve your skin texture.

If you don't have acne but struggle with oily skin, niacinamide can help regulate oil also.

This study found that 2% niacinamide is effective at lowering the sebum levels and the rate of sebum excretion.This is different from most topical treatments for oily skin which try to absorb the excess sebum. Niacinamide can actually slow down how much oil is released with changes becoming evident after two to four weeks.



Niacinamide is an effective solution at shrinking the appearance of pores. Niacinamide and salicylic acid significantly helped smooth skin texture and reduce pore size in a 12-week study cited in Cosmeceutical and Cosmetic Practice.

Niacinamide prevents the deterioration of enzymes known as NADH and NADPH, responsible for keeping our skin supple as we age.

When the pores are clogged, they appear larger due to the overproduction of sebum, causing the skin to be rough. Niacinamide significantly helps reduce the size of skin pores.

Niacinamide normalizes the pore lining. It keeps skin moisturized and enhances the skin's elasticity. It prevents dirt, oil, and bacteria from clogging the pores.



Niacinamide helps treat acne-prone skin due to its anti-inflammatory properties by preventing a particular protein complex from inflammation.

It also curtails the production of specific inflammatory cytokines to prevent redness and swelling caused by acne, eczema, rosacea, and other skin conditions, which often bring discomfort.



Niacinamide reinforces the production of keratin, an essential protein found in the epidermis. Keratin creates a protective layer on the surface of the skin and helps cells bond together. It protects the other cells from damage and helps promote smoother and more supple skin.


According to The Journal of Clinical Aesthetic Dermatology, the skin’s antioxidant ability is amplified after niacinamide’s topical application. It protects the skin from the damage of free radicals and oxidative stress.

Niacinamide acts as antioxidants that help restore skin cells and protect them from the sun’s harmful rays and other free radicals.

It minimizes the effects of sun damage and aids in strengthening the skin barrier. As a result, the skin becomes plump and younger-looking.




Due to the increase in collagen production caused by niacinamide, it can also help lighten the appearance of dark spots.

Niacinamide blocks enzymes that cause hyperpigmentation, such as age spots, sun spots, and melasma. This enhances skin tone to reveal clearer and brighter skin.

Several studies have found that niacinamide proved to be an effective treatment for pigmentation, age spots, and melasma.

After four weeks of niacinamide treatment, a study found a significant decline in hyperpigmentation with as little as 2% of niacinamide.

Another study found that 4% niacinamide has similar results to 4% of hydroquinone as a melasma treatment. However, niacinamide is much safer and has fewer side effects.



The lipid barrier consists of waxy fats that help form the skin barrier, maintaining the skin’s natural moisture. Over time, ceramides can be inadequate, causing several skin concerns such as dryness and sensitivity.

Studies have shown that niacinamide can improve the epidermal barrier function. It helps rejuvenate and reconstruct the surface of the skin against dehydration and moisture loss. A healthy and robust lipid barrier brings about fresh and young-looking skin.


According to a study, topical application of niacinamide increases NADP ( Nicotinamide adenine dinucleotide phosphate), a vital coenzyme in the cell. NADP stimulates keratinocyte to move to the outer layers of the dermis. As a result, the stratum corneum or the outermost layer of the skin becomes denser. This means that the skin barrier is stronger and the hydration retention capacity of the outer layer of the skin is maximized.




Topical niacinamide is generally safe to use for all skin types. It can be well tolerated by those sensitive to topical retinoids and fruits acids, including pregnant and breastfeeding women.

However, those who have preexisting allergies may experience allergic reactions as niacinamide may stimulate your body to release histamines. In very rare cases, topical niacinamide can cause a mild burning sensation, itchiness, or redness. If this happens, you can try a lower concentration of niacinamide.

Most clinical studies observed results using 2% to 5% percent concentrations of niacinamide, but some products contain 10 to 12% concentration. It is best to seek advice from a medical professional before using a higher concentration, especially if you have other medical conditions.

Like any other skincare ingredient, when you are new to niacinamide, doing a patch test is necessary to avoid allergic reactions and irritations.



For the most optimal results at treating acne, niacinamide may be used alongside zinc, copper, and folic acid.

When used with hyaluronic acid, niacinamide is better absorbed by the skin, providing it with intense hydration.


Niacinamide and Vitamin C

Niacinamide is suitable for all skin types, although those with sensitive skin should be extra careful if combining niacinamide with other products containing vitamin c. It is best to apply vitamin c in the morning and then niacinamide in the evening. If you don’t have sensitive skin, you should be able to tolerate using niacinamide and vitamin c together.

If you are new to niacinamide, like other beauty ingredients, doing a patch test can prevent allergic reactions. A simple method of doing a patch test is to slather a dime size amount on your forearm. Observe if you experience any itchiness, redness, or swelling over a 24-hour span. Do not continue to use if you experience any sign of a reaction.
