Niacinamide
Niacinamide, also known as Vitamin B3 or nicotinamide, is a water-soluble vitamin widely used in skincare for its versatility, stability, and high tolerance across all skin types. It is one of the most well-researched and effective ingredients for improving skin barrier function, reducing inflammation, balancing oil production, and addressing signs of aging and discoloration.
Unlike many active ingredients, Niacinamide is non-acidic and does not cause exfoliation, making it especially suitable for sensitive, oily, acne-prone, and aging skin. It is commonly found in serums, moisturisers, toners, and treatment products targeting issues like enlarged pores, uneven tone, dullness, and fine lines.
❓What It Does in Skincare
- Improves skin barrier function by boosting the production of ceramides and strengthening the outermost layer of the skin.
- Reduces the appearance of enlarged pores and helps regulate excess oil production.
- Brightens dull skin and evens out uneven skin tone by inhibiting the transfer of melanin to the skin’s surface.
- Soothes inflammation, making it beneficial for acne, rosacea, and sensitive skin conditions.
- Minimises the appearance of fine lines and wrinkles through improved elasticity and skin hydration.
- Enhances skin texture and overall clarity with regular use.
🧬Safety & Toxicology
- Considered very safe and well-tolerated by all skin types, including sensitive and acne-prone skin.
- Non-irritating and non-sensitising at typical cosmetic concentrations (usually 2% to 10%).
- Low risk of side effects, though higher concentrations may cause mild flushing in rare cases, especially when combined with acidic products.
- Stable in a wide range of pH levels, making it compatible with most other ingredients in skincare formulations.
- Non-toxic with no known long-term safety concerns when used topically.
- Can be used both morning and night, often in combination with other actives such as retinol, hyaluronic acid, and peptides.
