What is Niacinamide?

Niacinamide, also known as Vitamin B3, is a versatile ingredient that offers a wide range of benefits for the skin. Known for its ability to soothe, restore, and protect, it's a must-have for addressing common concerns like redness, uneven skin tone, and enlarged pores. Niacinamide can:

• Reduce Redness: With anti-inflammatory properties, niacinamide calms irritation and reduces redness caused by conditions like acne, rosacea, or sensitivity.
• Brighten Skin Tone: It helps fade dark spots and hyperpigmentation, promoting a smoother, more even complexion over time.
• Strengthen the Skin Barrier: By supporting the production of ceramides, niacinamide fortifies the skin's natural barrier, locking in moisture and protecting against environmental damage.
• Minimize Pores: Regulating excess oil production, niacinamide reduces the appearance of enlarged pores and improves overall texture.

Different Strengths of Niacinamide

Niacinamide serums vary in strength. Here is a general overview:

Niacinamide serums come in different strengths, each offering varying levels of benefits.

• A sprinkle of niacinamide (less than 5%) is ideal for sensitive skin or beginners, offering gentle brightening and hydration without overwhelming the skin.
• A low percentage (around 5%) helps with mild redness, pore size, and improving overall skin texture.
• The standard 10% strength is more potent, targeting dark spots, inflammation, and visibly improving uneven skin tone (this is the Anua serum!).
• For advanced users, a 20% concentration provides stronger effects but may cause irritation for sensitive skin types, making it best for those tackling severe hyperpigmentation or stubborn skin concerns.
