Niacinamide for Skin: Does It Brighten, Whiten, or Remove Tan and Acne Scars?

Few skincare ingredients have achieved cult status quite like niacinamide. Its popularity among dermatologists has now reached the masses, with Niacinamide serums becoming a skincare staple. You can even find it in moisturizers, toners, and sunscreens. 

Niacinamide for skin isn’t just overhyped; it has been scientifically proven to brighten skin. A study by National Library of Medicine revealed that Niacinamide effectively decreases hyperpigmentation. From reducing pigmentation, dark spots to tanning, it's even touted to have skin brightening benefits. Hence, it's a cornerstone ingredient in Deconstruct’s skincare range.

Despite its popularity, Niacinamide is fairly new to many skincare users. In this blog, we answer your burning questions like: What does niacinamide face serum do? Does niacinamide brighten skin? Does niacinamide whiten skin?

What is Niacinamide and how does it work on skin

Wondering what Niacinamide is? You aren’t the only one. Niacinamide, also called Nicotinamide, is a lab-stabilized form of Vitamin B3 (niacin). 

Naturally found in meat, fish, eggs, avocados, and more, Niacinamide is a multitasker for skin. It regulates the transfer of melanin, reducing the appearance of pigmentation and dark spots. 

Niacinamide serums even boost ceramide production, thus strengthening the skin’s barrier. The best niacinamide serums and moisturizers lock in hydration. It even balances oil production, thus helping oily skin with acne issues.

Regular use of Niacinamide for skin also gives anti-aging benefits, especially when paired with Retinol. By working on your skin barrier, Niacinamide keeps your skin plump and healthy-looking for long.

Does Niacinamide Brighten Skin?

Before studying Niacinamide’s use for skin brightening, it's key to know the difference between brightening and whitening. Brightening refers to evening out skin tone, reducing dullness, and restoring skin’s radiance. Whitening, on the other hand, refers to changing the skin’s tone entirely. 

While Niacinamide does the former, it doesn’t do the latter. The skincare active reduces dullness and improves uneven skin tone. The National Library of Medicine study reveals, Niacinamide inhibits the transfer of melanin from the skin’s bottom to the upper layer. Hence, consistent usage of Niacinamide serums or face cleansers makes your skin appear brighter in the long run.

A study in the Journal of the American Academy of Dermatology revealed that a 5% concentration of Niacinamide for skin reduced redness and skin damage caused by the sun’s UV. Hence, it reduces dark spots and dullness caused by the sun. Its consistent usage is proven to have brightening effects.

Can Niacinamide Whiten the Skin?

No, Niacinamide is used for skin brightening, but it does not bleach your skin. Hence, it cannot whiten the skin. 

In the cosmetic world, “whitening” refers to changing your skin’s natural tone overall. While many skincare clinics claim to offer skin whitening treatments today, the term “whitening” can be a problematic one. It risks spreading harmful stereotypes and furthering systemic discrimination based on skin color.

Niacinamide for skin lightens hyperpigmentation and dark spots by inhibiting melanin production. It even reduces redness and locks in moisture, giving your skin a brightened look. But it does not whiten your skin.

Is Niacinamide Effective in Removing Tan?

Niacinamide serums and other skincare products with the active ingredient are useful for removing tanning. But what is tanning?

Tanning is your skin’s defensive reaction to UV exposure. When UV rays penetrate deep layers of your skin, they stimulate the production of melanin, thus leading to pigmentation and tanning. This is where Niacinamide comes into the picture. The ingredient slows down melanin transfer, thus reducing tanning due to sun rays.

However, Niacinamide isn’t the only tan-reducing active out there. Vitamin C and Alpha Arbutin also have detanning properties.

Niacinamide is better suited for sensitive skin than Vitamin C and Alpha Arbutin. It's more gentle, while the other 2 ingredients may occasionally cause a little irritation for new skincare users.

Pairing niacinamide serums with sunscreens can give excellent results. While sunscreen shields against UV damage, niacinamide minimizes the long-term pigment changes triggered by UV. 

Niacinamide for Acne Scars and Old Marks

Few things are more stubborn than post-acne marks. However, Niacinamide is an effective solution for this skin concern. Balancing your skin’s oil production reduces acne and acne marks. But if you already have pre-existing ones that won’t budge easily, it can fight them too. 

Niacinamide calms redness and inflammation that occurs on your skin post-acne. It helps fade fresh scars within weeks and even older scars. But if you have deep tissue damage or scars from 2-3 years ago, this ingredient alone won’t suffice.

 Your deep dermal marks may require more aggressive treatments, as Niacinamide is best suited for more surface-level pigmentation.  

A 5% Niacinamide concentration paired with 2% Alpha Arbutin can cure uneven skin tone, pigmentation, and other similar issues effectively. Using Niacinamide with Retinol can aid in giving your skin a plumper look over time. Retinol works on post-acne marks and fine lines, but can be a bit harsh for skincare beginners. Niacinamide’s hydration-boosting properties protect against dryness and potential irritation that Retinol may cause.
