When we think about skin that feels hydrated, balanced, and healthy, one ingredient often comes to mind: niacinamide. You’ve likely already spotted it on a few of your favorite products’ labels. The answer is in its versatility. Niacinamide offers multiple benefits, addressing a variety of common concerns at once.
Uneven tone or dark spots? It can help. Sensitive skin? It soothes and comforts. Looking to smooth the appearance of fine lines? That’s why niacinamide has become a must-have for any routine aimed at achieving healthy, luminous skin.
What is Niacinamide?
Niacinamide, also known as vitamin B3, is a water-soluble vitamin naturally found in foods such as grains, milk, and meat. It is one of eight B vitamins that support many aspects of your health. Your body makes niacinamide when you have too much niacin in your body (you get niacin from foods like whole grains, meat and milk). Your body can also change an amino acid called tryptophan into niacinamide. But when it comes to skincare, you apply niacinamide topically to your skin.
Niacinamide is a type of vitamin B3. While more research is necessary, taking niacinamide may help reduce inflammation, improve skin elasticity, and more. Preventing B3 deficiency is important because it can lead to disorders of the skin, kidneys, and brain. But there’s much more to niacinamide, especially when it comes to general skin health.
Niacinamide is a multipurpose skin care ingredient that’s been shown to make your skin stronger, smoother, and brighter. You can use niacinamide for skin issues, and it can help nourish and protect your skin, especially when it’s used with other products like retinol.
Niacinamide is a well-known ingredient in modern skincare, gaining popularity for its versatile benefits. Niacinamide is a water-soluble form of vitamin B3 that offers solutions for a range of skin concerns. Also known as niacin or nicotinamide, niacinamide is a nutrient essential for human health. Niacinamide was initially used as a dietary supplement and made its way to the world of skincare. As a topical application, it was used to target the appearance of uneven skin tone and more recently has shown that it can target signs of aging, enlarged pores, and dry skin.
Key Characteristics of Niacinamide:
- What it is: A form of vitamin B3.
- What it does: Helps improve hydration, reduce the look of dark spots and redness, balance excess oil, and smooth wrinkles.
- Who it’s for: Suitable for all skin types.
- How to use it: Commonly found in both day and nighttime eye creams, serums, and moisturizers.
- Goes well with: Retinal, peptides, carnosine, hyaluronic acid, and gentle exfoliating acids.
- Don’t mix with: Vitamin C (ascorbic acid) at the same time.
Benefits of Niacinamide for Skin
Overall, niacinamide can help build proteins in the skin and lock in moisture to prevent damage. More research is necessary to understand the possible benefits in more detail.
Improves Skin Elasticity
Niacinamide helps widen the space between keratin molecules. Keratin is a type of protein that keeps your skin firm and healthy. This could help improve skin elasticity.
Strengthens the Skin Barrier
Niacinamide may enhance the function of your skin’s lipid barrier, a layer of water and oil that protects your skin. This helps lock moisture in and keep pollutants or other potential irritants out, making your skin more hydrated and less sensitive. A strong skin barrier supports your skin’s natural repair and recovery process by helping it hold onto moisture and defend against everyday stressors. When your skin barrier is healthy, your skin is better able to tolerate active ingredients, reducing the risk of irritation. It also creates a stable foundation, allowing skincare products to absorb and work more effectively for healthier, more balanced skin.
“When the skin barrier is damaged, skin struggles to retain moisture and protect itself from irritants,” explains Yanke. “This can lead to dryness, sensitivity, redness, and increased breakouts.”
Niacinamide helps strengthen the skin’s lipid barrier, which is crucial for maintaining moisture and protecting against environmental aggressors. By supporting the skin’s natural content of ceramides and fatty acids, niacinamide helps to prevent transepidermal water loss, keeping the skin hydrated and resilient.
Reduces Inflammation and Redness
Niacinamide can help reduce inflammation, which may help ease redness or discoloration. This could help manage inflammatory skin conditions such as psoriasis, atopic dermatitis, and contact dermatitis.
Niacinamide has been shown to ease inflammation, which can help calm redness due to conditions like acne, rosacea, and eczema. It can also soothe irritation caused by strong exfoliants, like retinol or glycolic acid, that remove dead cells from the surface of your skin.
Regulates Oil Production
Niacinamide may help regulate the amount of oil the sebaceous glands produce. This could be helpful for people with oily skin, though more research is necessary.
“Niacinamide helps regulate oil production by supporting the skin’s natural balance. It regulates sebaceous gland activity by signaling the skin to stay hydrated, reducing the need for excess oil,” says Yanke. “It also calms inflammation, making the skin less reactive, and supports overall barrier health, which helps maintain balanced oil levels over time.”
Improves Skin Appearance
Niacinamide can be helpful for treating skin hyperpigmentation or pigmentation disorders. It may also help reduce the appearance of fine lines and wrinkles.
Treats Dark Spots
Niacinamide is dermatologist-approved for brightening skin tone. Some research suggests skincare formulas with 5% niacinamide can also help lighten dark spots.
In one study, a combination of skin brighteners, including retinol and niacinamide, reduced dark spots and fine lines. They also improved skin radiance and texture.
Reduces Wrinkles and Fine Lines
This vitamin’s antioxidant properties may help protect your skin and aid its recovery from damage due to factors like aging, sun, and stress, says Yanke. Applying a topical niacinamide may improve fine lines and wrinkles, as well as skin sallowness.
“Niacinamide helps reduce the appearance of fine lines and wrinkles by boosting collagen production, which improves elasticity, and by supporting a healthy skin barrier that keeps skin hydrated and plump,” she adds. “Creating a plump look on the skin helps soften the appearance of any fine lines and wrinkles. Niacinamide also increases cellular turnover, smoothing texture and helping the skin look brighter and more youthful.”
Protects Against Oxidative Stress
Niacinamide helps build skin cells while protecting them from environmental stresses, such as sunlight, pollution, and toxins.
Treats Acne
Niacinamide may be helpful for managing acne. However, more research is necessary to better understand this potential. Other products for acne may be more suitable.
Reduces the Appearance of Pores
Nothing has been proven to reduce the actual size of your pores. But niacinamide may help minimize their appearance by helping keep your skin smooth and clear.
“Niacinamide helps reduce the appearance of pores in a few ways. By strengthening the skin barrier and improving elasticity, pores appear less noticeable and more even,” shares Yanke. “It also boosts cell turnover, which smooths skin texture and keeps pores clear. As a result, the skin looks smoother, with a more even complexion and visibly smaller pores.”
How to Use Niacinamide
Niacinamide can be added into both your morning and nighttime routine. Yes, niacinamide is gentle enough for daily use, both morning and evening. Consistency is key.
Niacinamide Combinations:
- Niacinamide + hyaluronic acid: A hydrating power couple.
- Niacinamide + retinal: Ideal for well-aging routines.
- Niacinamide complements retinoids: Helping to minimize potential dryness or redness.
Expert Tip for Using Niacinamide:
To get the most from niacinamide, use it separately from vitamin C. Try vitamin C in the morning and niacinamide in the evening.
Most skincare products contain 5% niacinamide or less, but amounts can vary. Start slowly with a low concentration if you have sensitive skin.
It’s often helpful to pair niacinamide with other skincare products to maximize its benefits. These include anti-aging formulas with antioxidants, Vitamin C, moisturizers with ceramides, glycolic acid, hyaluronic acid, and retinol.
Generally, niacinamide can be used once or twice daily after gentle cleansing during your regular skincare routine. To maximize its benefits, apply niacinamide after applying a moisturizer. You can also combine a niacinamide serum with your moisturizer and apply them together to your face and neck. Or try a face mask that contains niacinamide for skin recovery and relaxation.
“You can even find niacinamide in some sunscreens these days,” notes Yanke. “Just make sure you’re not using too many skincare products with it at once.”
Specific Product Recommendations and Usage:
- Niacinamide 10% + Zinc 1% Serum: This water-based serum boosts skin brightness, improves skin smoothness, and reinforces the skin barrier over time. It contains a high 10% concentration of Niacinamide (vitamin B3) and zinc PCA. When incorporating this into your regimen, use it as part of the "Treat" step after cleansing. Because it's water-based, it can be applied before anhydrous, creams, or emulsions. It layers well with ingredients like Hyaluronic Acid 2% + B5. Avoid pairing with direct or indirect Vitamin C, as it can reduce the effectiveness of both ingredients.
- Niacinamide 5% Face and Body Emulsion: This formulation can be used on the body and face, addressing concerns like dark spots, uneven skin tone, and uneven texture. The 5% concentration is milder, making it suitable for sensitive skin or for a gentler introduction to niacinamide.
For Signs of Aging:
After cleansing, apply Niacinamide 10% + Zinc 1%. Layer with a Multi-Peptide + HA Serum next. For your PM routine, try applying Retinal 0.2% Emulsion after Niacinamide 10% + Zinc 1% for additional support for signs of aging. (Start with 1-2 applications a week for the first few weeks until skin is acclimated).
For Signs of Congestion:
After cleansing, follow with Niacinamide 10% + Zinc 1% (can be used morning and evening). Once a week in the PM, apply a Salicylic Acid 2% Masque to exfoliate after cleansing. After the masque, apply the Niacinamide 10% + Zinc 1% before the next step.
For Uneven Skin Tone:
Add Glycolic Acid 7% Exfoliating Toner after cleansing. Follow with Niacinamide 10% + Zinc 1% (can be used morning and evening).
For Dry Skin:
Add Hyaluronic Acid 2% + B5 before or after Niacinamide 10% + Zinc 1% for an added hydration boost.

Niacinamide Side Effects and Precautions
Niacinamide is generally considered gentle and safe to use on your skin. Rarely, it can cause:
- Allergic reaction
- Itching
- Mild burning sensation
- Redness
“If you’re concerned about potential side effects, do a patch test by applying a small amount on your forearm and waiting 24 hours,” Yanke advises. “Most of the time, you’ll be able to use niacinamide safely and discover your skin is all the better for it.”
To do a patch test before using the product:
- Apply a dime-sized amount of product on your forearm.
- Wait 48 to 96 hours.
- If you experience redness or discoloration, itching, or swelling in the area, wash the area and discontinue use.
- If you don’t experience any side effects, it should be safe to apply elsewhere.
People with preexisting allergies may be more likely to experience an allergic reaction, as niacinamide can cause your body to release histamine.
It’s best to contact a doctor before adding niacinamide products to your skincare routine.
You should not take niacinamide supplements unless your doctor or other healthcare professional recommends them.
Timeline for Results
As with any new skincare product, you probably won’t see any significant results immediately. Although most of the available research looked at the use of niacinamide for around 4 to 12 weeks, there’s no exact timeline. Improvements in tone, texture, and hydration are often noticeable after a few weeks of use. Remember, your skin naturally renews itself about every 28 days-so typically, you’ll start to notice results around then.
If you don’t see any changes within a couple of months, it may be time to consult with a dermatologist. They can assess your skincare routine and advise you on which products to use, any dietary changes that may improve your skin health, and more.
Niacinamide vs. Niacin
Despite the similarities in names, niacinamide isn’t the same thing as niacin. Niacinamide is the water-soluble form of niacin, or vitamin B3.
Conclusion on Niacinamide
Topical niacinamide may have a positive impact on overall skin health. It helps reduce inflammation and hyperpigmentation, smooth fine lines and wrinkles, and more. While more research is necessary, niacinamide could benefit conditions such as dermatitis, psoriasis, and acne.
Niacinamide is a versatile and powerful ingredient that offers numerous benefits for various skin types and concerns. From its historical use to its modern-day applications, niacinamide continues to be a vital component of effective skincare routines.
Whether you're using a niacinamide serum or an emulsion, you can achieve healthier-looking skin.
And don’t forget: beautiful skin also starts from within. Aim to eat well, sleep well, and stay hydrated.
