Niacinamide is a type of vitamin B3 that is found in many skin care products to brighten skin, prevent signs of aging, and treat conditions like eczema or acne. It is a multipurpose skin care ingredient that helps build keratin, a protein that maintains skin health, and makes your skin stronger, smoother, and brighter. Here are some of the benefits of niacinamide:

• Boosts hydration: Niacinamide enhances the function of your skins lipid barrier, which helps lock moisture in and keep pollutants or other potential irritants out, making your skin more hydrated and less sensitive.
• Calms redness: Niacinamide has been shown to ease inflammation, which can help calm redness due to conditions like eczema, acne, and other inflammatory skin conditions.
• Minimizes pore appearance: Niacinamide regulates excess sebum production and keeps pores from appearing large and congested, which helps minimize pore size.
• Treats hyperpigmentation: Niacinamide can help brighten and fade hyperpigmentation through the regulation of melanosome transfer, and some research has found that 5% niacinamide concentrations can be helpful in lightening dark spots.
• Minimizes fine lines and wrinkles: Niacinamide has been found to be helpful in reducing some signs of sun damage that come with aging, including fine lines and wrinkles.
• Protects against oxidative stress: Niacinamide helps build cells in the skin while also protecting them from environmental stresses, such as sunlight, pollution, and toxins.
• Treats acne: Niacinamide may be helpful for severe acne, especially inflammatory forms like papules and pustules. Over time, you may see fewer lesions and improved skin.

Niacinamide is also a natural anti-inflammatory ingredient, so its great for calming irritated skin and is safe for those with sensitive skin.
