10 science-backed facts about niacinamide:

  1. Improves Skin Barrier Function: Niacinamide helps strengthen the skin barrier by increasing the production of ceramides, which are essential for maintaining skin hydration and integrity. This helps to prevent moisture loss and protect the skin from external irritants. 

  2. Reduces Hyperpigmentation: Niacinamide inhibits the transfer of melanin (the pigment responsible for skin color) to the surface of the skin, leading to a reduction in hyperpigmentation, dark spots, and uneven skin tone. 

  3. Decreases Sebum Production: Niacinamide regulates oil production in the skin, making it beneficial for individuals with oily or acne-prone skin. By reducing excess sebum, niacinamide helps to minimize the occurrence of acne and breakouts. 

  4. Anti-Inflammatory Properties: Niacinamide exhibits anti-inflammatory effects by inhibiting inflammatory cytokines and enzymes in the skin. It can help reduce redness, inflammation, and sensitivity associated with conditions like acne, rosacea, and eczema. 

  5. Boosts Collagen Production: Niacinamide stimulates collagen synthesis in the skin, leading to improved elasticity, firmness, and overall skin texture. This can help reduce the appearance of fine lines, wrinkles, and signs of aging. 

  6. Protects Against UV Damage: Niacinamide has been shown to provide photoprotection against UV radiation by enhancing the repair of DNA damage and reducing inflammation caused by sun exposure. It complements the effects of sunscreen in preventing photoaging and sunburn. 

  7. Reduces Trans-Epidermal Water Loss (TEWL): Niacinamide helps to maintain skin hydration by reducing TEWL, the process by which water evaporates from the skin's surface. By strengthening the skin barrier, niacinamide prevents moisture loss and promotes optimal hydration levels. 

  8. Improves Skin Elasticity: Regular use of niacinamide has been shown to enhance skin elasticity and suppleness. By promoting collagen synthesis and increasing skin hydration, niacinamide helps to improve skin firmness and resilience.
