Niacinamide vs Vitamin C: learn which ingredient is better for acne-prone and oily skin, post-acne marks, dark spots, pigmentation, dullness and uneven skin tone. Understand how Niacinamide and Vitamin C work, their key differences, whether you can use them together, which one to apply first, and how to build a simple routine based on your skin type and concerns.

While both niacinamide and vitamin C are well-known for their effectiveness in skincare products, they do several different things to address pigmentation, acne marks, uneven skin tone, and dark spots. So, which is better: Niacinamide or Vitamin C? The better choice depends on your primary skin concern. Niacinamide helps regulate excess oil, support the skin barrier, and improve the appearance of post-acne marks, while Vitamin C provides antioxidant protection and can improve the appearance of dullness, uneven skin tone, and pigmentation. If your skin is able to handle both, you have the option to utilize Niacinamide and Vitamin C together. 

This guide compares Niacinamide vs Vitamin C for pigmentation, dark spots, acne marks, and different skin types, and explains how to use both together in a simple skincare routine. 

Niacinamide or Vitamin C: Which Is Better?

There is no universal winner between Niacinamide and Vitamin C. The better ingredient depends on what you want to treat.

1. Vitamin C: When sun exposure is a factor in skin dullness, uneven tone, or pigmentation, its antioxidant properties make it a good alternative to consider. 

2. Niacinamide: Niacinamide has shown effectiveness in treating acne scars, excessive oiliness, and skin tone imbalances. If you have sensitive or acne-prone skin, it could be a suitable place to start because it is usually well-tolerated. 

Choose Niacinamide if your main concerns are:

  • Excess oil
  • Acne-prone skin
  • Post-acne marks
  • Uneven-looking skin
  • Skin-barrier support

Choose Vitamin C if your main concerns are:

  • Dull-looking skin
  • Uneven skin tone
  • Dark spots and pigmentation
  • Antioxidant protection
  • Supporting collagen synthesis 

For Foxtale shoppers, the 12% Niacinamide Clarifying Serum is a targeted option for oily, acne-prone skin and post-acne marks, while the 10% Vitamin C-Glutathione Advanced Brightening Serum is better suited to dullness, uneven skin tone and pigmentation. 

Pro tip: Niacinamide can help improve the appearance of pigmentation and uneven skin tone when used consistently. It might feel difficult to choose the right niacinamide concentration, but the right guide may help you choose the ideal product according to your skin requirements. 

How Do They Work? 

Niacinamide, a form of vitamin B3, supports the skin barrier, helps regulate excess oil, and can improve the appearance of uneven skin tone and post-acne marks. Studies on topical niacinamide have also shown benefits for the appearance of hyperpigmentation. 
 

The antioxidant properties of vitamin C aid in enhancing the protection of skin cells against oxidative stress and in the stimulation of collagen production. Additionally, with regular usage, it can help improve the appearance of dullness, uneven skin tone, and pigmentation.
 

Instead of having to pick between the two, you may use Niacinamide and Vitamin C together as they both focus on different aspects of skin health.

When tolerated, these ingredients can be used together to target different aspects of dullness, uneven skin tone, pigmentation, and post-acne marks.

Morning Routine

  • Gentle cleanser
  • Vitamin C serum
  • Niacinamide serum
  • Moisturizer
  • Broad-spectrum SPF 50 sunscreen

Night Routine

  • Gentle cleanser
  • Niacinamide serum
  • Hydrating moisturizer

Pro tip: If you have sensitive skin, start with lower concentrations and use the products every other day before slowly adding them into your daily skincare routine. 

Which Goes First: Vitamin C or Niacinamide? 

When using both products in the same morning routine, apply Vitamin C first, followed by Niacinamide, moisturizer, and sunscreen. Always follow the application instructions for your specific products.  As a rule of thumb, always refer to the product's instructions for texture and application. 

What Is Vitamin C & How Does It Benefit Your Skin?

Vitamin C is a potent antioxidant that helps protect skin from oxidative stress and can improve the appearance of dullness, uneven skin tone, and pigmentation. In addition to supporting brighter-looking skin, Vitamin C can:

  1. Boost collagen production
  2. Defend against oxidative stress
  3. Improve overall skin radiance
  4. Support brighter-looking skin

What Is Niacinamide & How Does It Help With Dark Spots & Pigmentation? 

Niacinamide is a form of vitamin B3 that supports the skin barrier, helps regulate excess oil, and can improve the appearance of post-acne marks and uneven skin tone. 

Key Benefits of Niacinamide

  • Helps improve the appearance of dark spots and post-acne marks 
  • Reduces redness and inflammation
  • Strengthens the skin barrier
  • Regulates the production of extra oil

Pro tip: Niacinamide can be a useful option for oily, acne-prone, or sensitive skin because it supports the skin barrier while helping regulate excess oil and improve the appearance of post-acne marks. When used regularly over time, niacinamide's science-backed compatibility with your skin works effectively for sensitive, oily, and acne-prone skin. 

Niacinamide vs Vitamin C for Pigmentation: Which Is Better? 

Although they have distinct mechanisms of action, niacinamide and vitamin C both have the potential to reduce the visibility of pigmentation. Vitamin C may be particularly useful for dullness, uneven tone, and sun-related pigmentation, while Niacinamide can be especially useful for post-acne marks alongside its oil-control and barrier-supporting benefits.  For pigmentation accompanied by excess oil or post-acne marks, Niacinamide may be the better starting point. If dullness, uneven tone or sun-related pigmentation is the main concern, Vitamin C may be a better fit.

Which Is Better for Your Skin Type? 

The better choice also depends on your skin type and primary concern. Here's how Niacinamide and Vitamin C compare for oily, dry, sensitive, and Indian skin. Both are powerful brightening agents, but they target dullness, uneven skin tone, dark spots, and acne marks in distinct ways.

Here's how to choose the one that works best for your skin:

1. For Skin That Is Oily and Prone to Acne

If you have oily or acne-prone skin and are concerned about excess oil, breakouts, or post-acne marks, niacinamide is usually a good place to start. In addition to improving the appearance of post-acne marks, it helps control sebum production and strengthens the skin's protective barrier.

Concerns including overproduction of sebum, acne, and dark patches are the inspiration for Foxtale's 12% Niacinamide Serum, which combines Niacinamide with Azelaic Acid and is formulated for concerns such as excess oil, acne, and the appearance of dark spots.  If you're worried about your skin seeming dull or uneven in tone, you can add vitamin C if your skin can handle it. Check out our beginner's guide to Vitamin C serum if you're wondering if vitamin C is appropriate for skin prone to breakouts. To comprehend how it functions in conjunction with active acne. 

2. For Dehydrated and Dry Skin

For dry or dehydrated skin, neither ingredient is automatically better. Niacinamide and vitamin C work together to strengthen the skin's protective barrier and alleviate signs of dullness and uneven tone. Once your skin is ready, you may apply both of these products in addition to a hydrating moisturizer and a daily SPF 50 sunscreen

The lightweight gel-cream texture of Foxtale's Super Glow Moisturizer with Vitamin C helps lighten pigmentation while providing intense hydration. It also improves the general clarity and brightness of the skin since it contains niacinamide.

3. For Sensitive Skin

For sensitive or easily irritated skin, Niacinamide may be a better starting point because it is generally well tolerated and supports the skin barrier. Start gradually and reduce frequency if irritation occurs. If you're considering a higher-strength Niacinamide formula, introduce it gradually rather than assuming a higher concentration will work better for sensitive skin.

4. For Indian Skin Type: 

What matters more than skin tone when it comes to Indian skin is the primary skin concern. For skin that's oily, acne-prone, or has post-acne scars, niacinamide can be a good choice; for skin that's dull, uneven in tone, or has pigmentation from the sun, vitamin C can be better. If you're dealing with more than one issue at once and your skin is tolerating both, you can apply them together. 

Conclusion

There is no one ‘better’ ingredient when it comes to niacinamide vs. vitamin C. It all depends on your skin type, issues, and skincare goals. Niacinamide strengthens the skin barrier, controls excess oil, and fades acne scars, while vitamin C brightens dull skin and lessens sun-induced pigmentation. Fortunately, you don't have to decide between the two. 

When combined, niacinamide and vitamin C can more successfully address dullness, uneven skin tone, and dark spots. Over time, you can get healthier, more balanced-looking skin by combining these substances with a mild skincare regimen and regular sunscreen. Discover beginner-friendly formulas in Foxtale's science-backed skincare range to assist you in creating the ideal skin-brightening regimen.

These are the skincare ingredients you shouldn’t layer with each other, EVER

August 12, 2021

3 min read

Peanut butter and jelly, Ben Affleck and Jennifer Lopez, Vitamin C and ferulic acid. Some matches are made in heaven. But in the realm of lotions and potions, mixing and matching could be risky business instead. Learning to (not to) layer skincare is an art.

The benefits of your favourite skincare actives—Vitamin C! Niacinamide! Retinoids!— are all over the internet. It is easy to fall prey to the cure-all layering routines that promise smooth, poreless skin in just a few weeks. But that get-glow-quick scheme can leave your skin overstimulated if you’re whipping dangerous skincare cocktails. These are not only be harmful together, but could also cancel each other out. If you’re a neophyte, you may want to keep these ingredient non-pairings in mind before putting your routine together.

Retinoids + Vitamin C = redness, irritation and potential sunburns.

Retinoids are Vitamin A derivatives that rev up skin cell turnover. This unclogs dead skin cells and helps improve collagen production. Vitamin C is an antioxidant that blocks tyrosinase production (which is responsible for pigmentation) and scavenges free radicals too. Both these powerhouse ingredients are anti-ageing marvels. But when layered together, they leave your skin photosensitive, which can increase chances for sun damage. These ingredients have a huge pH gap, so if you wear both together, you could be lowering the retinoid’s pH and raising the Vitamin C’s pH levels. This means that both ingredients could be rendered useless. For best results, use a Vitamin C serum in the AM and then apply a Vitamin A-based product on at night.

Retinoids + Alpha Hydroxy Acids = raw, painful skin.

Retinoids and AHAs (like lactic or malic acid) both improve cell turnover, bolster collagen production and promise to leave your skin blemish, fine line and pigmentation-free. But if you’re tempted to use both together in an attempt to get brighter skin quicker, wait! Both remove dead skin layers on the top, thinning out the skin in the process. This can cause contact dermatitis, burns or scarring, especially if your skin isn’t used to exfoliation.

Retinoids + Benzoyl Peroxide = Irritation, and zero effects.

The theme here is to use retinoids carefully—they’re good servants, but bad masters. This is especially so when used with benzoyl peroxide. The two anti-acne ingredients work in very different ways, and may actually cancel out each other when used together. Benzoyl peroxide is able to kill the p.acnes bacteria that causes acne. Because when it is applied, it degrades and releases oxygen, which is able to kill the bacteria on the surface. Retinoids, on the other hand, work by reducing comedone creation by reducing pore obstructions by keratin and debris.

Benzoyl Peroxide + Vitamin C = no results.

If you have a zit and a patch of pigmentation, you may want to fix both, ASAP. But if you spot treat with BPO and then apply a Vitamin C-based toner, neither will actually work. Benzoyl peroxide works by creating oxygen, which oxidises the already-unstable L-ascorbic acid molecules, rendering them both useless.

We did an in-depth dive into the perils of acne and how to fix them, here.

Niacinamide + AHAs = potential irritation and redness.

Niacinamide helps restore cellular energy, repair damaged DNA, which makes it a cure-all ingredient that most pros love to suggest. While some people can tolerate these two ingredients together, some with sensitive skin may be worried about the niacin flush—which occurs when niacinamide hydrolyses into nicotinic acid when combined with an acidic product. This conversation can cause facial flushing, which can result in redness and tingling.

There really can be too much of a good thing—and some power duos are best used separately instead of together. It might be best to ease in actives and space them out, because too many strong ingredients–while they may feel satisfying in the short run—can hurt more than they can help.

Sometimes DIY skincare can do more harm than good

August 24, 2021

When you’re inundated by skincare brands and products that claim to be your best option, it is fair to wish for simple solutions that promise to solve your issues in the most natural way possible—using ingredients from your kitchen. DIY skincare seems safe. After all, your grandmother has been relying on her aloe vera & cucumber juice face mask recipe for years. While it might be an attractive prospect, and may even feel like the cleaner way, it leaves too much to chance. If you’re mixing things up in your kitchen in lieu of well-formulated skincare products, you could be playing too fast and loose. Here’s why.

It can mess with your skin’s pH and moisture barrier

A coconut oil and sugar scrub sounds like the perfect idea, but may take a no-prisoners-approach to your skin instead. Sugar particles are all different sizes and shapes, and the sharp edges may cause micro-tears in your skin. This may actually cause you to over-exfoliate without realising. Coconut oil is highly comedogenic. So while you might be using it to brighten skin, it can clog pores and cause breakouts in the long run.

Lemon—another DIY favourite—could damage your skincare barrier instead of fortify it. The skin has an acid mantle, which helps seal in moisture and keep skin firm. When it deviates too much from its median, the skin can get irritated. This can lead to acne, irritation and pigmentation. Lemon juice is super acidic (with a pH of 2) and can alter the skin’s pH, which is usually between 4-5, which–when messed with—can take a lot of TLC to nurse back to health.

You can’t trust the source of your ingredients

It is nothing like pharmaceutical-grade Vitamin C, which is formulated at a pH that won’t damage the skin. The neutralised ingredient is measured out and stabilized (and tested and then re-tested in a lab). This ensures that it won’t burn, sting or irritate the skin. It is also tested to make sure it works efficiently in that concentration or housed in that packaging. This is unlike a lemon from the grocery store, that could be non-organic or lying on the shelf for days. Even if the skincare product is using filtered lemon juice extracts, it’s in a well-researched high concentration to ensure efficacy.

Fruits and vegetables aren’t shelf-stable

Preservatives and parabens may sometimes get a bad rap. But they actually play a super important role in making topical skincare products safe, stable and actually effective. If you’re using eggs to mattify your skin or yoghurt to moisturise, you could inadvertently be introducing bacteria to your skin instead. They’re more perishable than you might assume.

Natural doesn’t have to mean better, safer or more effective

Consumers can sometimes fear the unknown, like ingredients they can’t read or pronounce (like niacinamide, glycosphingolipids and polyhydroxy acids). But these are high quality ingredients that do exactly what they promise to do, thanks to research and lab-testing. Plus, it is important to note that even in “natural” skincare products, ingredients have to be processed to make them safe enough to be bottled. Synthetic ingredients, on the other hand, are made in the lab to mimic these natural ingredients. These have any possible allergens or additions filtered out. Poison ivy is natural, but you don’t want it anywhere near your face, ever.

It is important to note that skincare is not a one-size-fits-all, and the aloe vera + apple cider vinegar + mashed banana + peach mask that works to brighten your friends skin? It might totally backfire on you (or it might just not work at all!). Instead, do your homework. Read ingredient lists, research labels and hold skincare brands that have done the research, work and due diligence accountable. This is how you can get what you really signed up for.
