Niacinamide (skincare)

What is Niacinamide (skincare)?

Niacinamide, also known as nicotinamide, is an active form of vitamin B3 that has become a popular ingredient in skincare. It is known for its many benefits for the skin, including strengthening the skin barrier, reducing the visibility of pores, evening out skin tone, and regulating sebum production. Niacinamide is a water-soluble vitamin well known for its ability to improve the overall health and appearance of the skin.

How does it work in the body?

Niacinamide works by affecting several biological processes in the body. It plays an important role in energy production by contributing to the synthesis of NAD (nicotinamide adenine dinucleotide), which is crucial for cellular processes such as metabolism and DNA repair. When applied topically to the skin, niacinamide can help improve skin hydration, reduce inflammation, and strengthen the skin’s barrier function, making the skin more resilient to harmful environmental factors.

Scientific benefits

Several studies have investigated the skincare benefits of niacinamide. Here are some of the most prominent benefits:

• Strengthens the skin barrier: A study published in The Journal of Clinical and Aesthetic Dermatology showed that niacinamide can improve the skin’s barrier function, reducing transepidermal water loss (TEWL).
• Regulates sebum production: Research has shown that niacinamide can reduce excess sebum production, which is particularly beneficial for people with oily skin and acne.
• Evens out skin tone: Niacinamide has been shown to reduce hyperpigmentation and uneven skin tone. A study from the International Journal of Dermatology confirmed this by demonstrating that participants experienced an improvement in skin tone after 12 weeks of niacinamide use.
• Reduces visibility of pores: By regulating sebum production and improving skin texture, niacinamide can help reduce the visibility of pores.

Dosage and recommendations

To achieve optimal results, it is recommended to use niacinamide in concentrations between 2-10% in skincare products. It is important to start with a lower concentration if you have sensitive skin to avoid potential irritation. Apply the product to cleansed skin, preferably once in the morning and once in the evening, depending on your skin type and the product formulation.

Best sources and forms

Niacinamide is found in many skincare products, including serums, creams, and toners. It is also possible to obtain niacinamide through dietary supplements, but it is always best to consult a doctor before starting any new supplements. Common skincare products containing niacinamide include:

• Serums
• Moisturisers
• Face masks
• Tonics

Side effects and warnings

Niacinamide is generally considered safe for most skin types. However, it can cause mild irritation, redness, or itching in some individuals, especially at higher concentrations. If you experience discomfort, it is best to reduce usage or consult a skincare professional. People with sensitive skin should also perform a patch test before using a new product containing niacinamide.
