Niacinamide, alternatively known as nicotinamide, is a variant of vitamin B3. It can be naturally obtained from a variety of food sources, such as meat, fish, milk, eggs, green vegetables, and cereals. The body relies on niacinamide for the proper use of fats and sugars, as well as for the maintenance of healthy cells. When the body receives an excess of niacin, it is converted into niacinamide. However, unlike niacin, niacinamide does not possess the ability to treat high cholesterol.

Niacinamide is commonly employed to safeguard against vitamin B3 deficiency and its associated ailments like pellagra. Although it is also used for various other conditions such as acne, diabetes, cancer, osteoarthritis, ageing skin, skin discoloration, and more, the majority of these uses lack substantial scientific evidence to validate their efficacy.

It's crucial to differentiate niacinamide from other substances like niacin, NADH, nicotinamide riboside, inositol nicotinate, or L-tryptophan, as they are distinct entities and should not be confused with one another.

Niacinamide has gained the endorsement of dermatologists for its myriad benefits, including skin brightening, blemish-clearing properties, and the ability to diminish fine lines and wrinkles. It aids in the production of keratin, a protein crucial for maintaining skin health. Additionally, niacinamide has been proven to enhance skin strength, smoothness, and radiance. Here are the various benefits of niacinamide for the skin:

Benefits of niacinamide

Moisture retention

Niacinamide possesses the ability to improve the efficacy of your skin's lipid barrier, which acts as a protective layer of water and oil. This enhancement helps to lock in moisture, ensuring your skin remains well-hydrated while effectively shielding it from pollutants and potential irritants. Consequently, your skin's hydration levels are boosted, and its sensitivity is reduced.

Boosts immunity

Niacinamide plays a crucial role in enhancing the immune system. It aids in the production of keratin, a protein that promotes firmness and health in the skin.

Strengthens the lipid barrier 

Niacinamide supports the development of a protective ceramide barrier in the skin. This lipid barrier helps to retain moisture, making it particularly beneficial for individuals with eczema or mature skin.

Reduces skin redness

Research has demonstrated that niacinamide has anti-inflammatory properties, making it effective in calming redness associated with conditions such as acne, rosacea, and eczema. Additionally, it can provide relief from irritation caused by potent exfoliants like retinol or glycolic acid, which eliminate dead skin cells from the skin's surface.

Reduces pore size

While there is no proven method to physically reduce pore size, the use of niacinamide has shown potential in minimising their appearance. Niacinamide works by promoting smooth and clear skin, which can give the illusion of smaller pores. Additionally, it has the ability to regulate oil production in the glands, thereby preventing breakouts and reducing the likelihood of clogged pores.

May protect skin cancer

There is a potential for skin cancer protection with the use of niacinamide. Niacinamide is closely related to another B vitamin called nicotinamide. In certain people, taking oral nicotinamide supplements may assist in preventing the formation of new skin cancer or precancerous spots. 

Dark spot treatment

Niacinamide has received the endorsement of dermatologists as an effective ingredient for enhancing skin tone. Emerging research indicates that skincare products containing 5% niacinamide may also contribute to the lightening of dark spots.

A blend of skin brighteners, such as retinol and niacinamide, had a positive impact on reducing dark spots and fine lines. Additionally, these compounds enhance skin radiance and texture.

Safeguards skin from wrinkles and fine lines

The antioxidant properties of Niacinamide can potentially safeguard your skin and facilitate its rejuvenation from various sources of damage such as ageing, sun exposure, and stress. Several studies suggest that applying niacinamide topically can enhance the reduction of fine lines, wrinkles, and even improve skin sallowness.

Conclusion

Daily topical use of niacinamide can greatly benefit your skin health. This ingredient possesses the ability to diminish inflammation and hyperpigmentation, enhance overall skin texture, and promote a brighter complexion. It is crucial to maintain consistency and patience while incorporating niacinamide into your skincare routine, as visible improvements may take a few weeks to become apparent. Unless specifically prescribed by a medical professional to address a B-3 deficiency or another underlying condition, it is not recommended to take niacinamide supplements.
