Quick Answer
Apply Anua Niacinamide 10% + TXA 4% Serum to clean, dry skin in the morning and evening, using 2-3 drops before moisturizer. Start with every other day to let your skin adjust, then build up to daily use.
Why This Serum Works for Brightening
Anua Niacinamide 10% + TXA 4% Serum combines 10% Niacinamide and 4% Tranexamic Acid to target dark spots and uneven tone. Niacinamide helps fade hyperpigmentation, while Tranexamic Acid corrects discoloration. The addition of Arbutin further supports a radiant, even complexion.
Because 10% Niacinamide is a higher concentration, it can be potent for some skin types. If you're new to niacinamide or have sensitive skin, patch test first and introduce it gradually to avoid irritation.
Key Considerations Before You Start
Consistency matters more than frequency. Using the serum daily after your skin adjusts gives the best results, but skipping days won't ruin your progress. Just don't double up to 'catch up'—that can irritate your skin.
This serum pairs well with a simple routine: cleanse, serum, moisturizer, and sunscreen in the morning. Avoid combining it with other strong actives like retinoids or AHAs at the same time, especially when starting out.
Step-by-Step: How to Use Anua Niacinamide Serum
- Cleanse and pat dry: Start with a gentle cleanser and pat your face dry. Apply the serum to clean, dry skin—damp skin can dilute the formula and reduce its effectiveness. Wait 2-3 minutes after cleansing to ensure skin is fully dry.
- Apply 2-3 drops to your face: Dispense 2-3 drops into your palm, then press gently onto your face and neck. Avoid the eye area and any broken skin. A little goes a long way. Don't rub vigorously—patting helps absorption and reduces friction.
- Wait for absorption: Give the serum 1-2 minutes to sink in before moving to the next step. If it feels sticky, you've used too much—next time reduce the drops. The serum should feel dry to the touch before layering.
- Layer with moisturizer: Follow with a moisturizer to lock in hydration and buffer the active ingredients. This is especially important if your skin is sensitive or you're new to niacinamide. Moisturizer helps prevent dryness and irritation.
- Use AM and PM, with SPF in the morning: Apply twice daily for best results. In the morning, always finish with a broad-spectrum sunscreen (SPF 30 or higher) to protect your skin and prevent new dark spots. Sunscreen is non-negotiable when using brightening actives.
- Start slow and adjust: If you're new to 10% niacinamide, use the serum every other day for the first week, then increase to daily if no irritation occurs. If you experience redness or stinging, reduce frequency or pause use. Listen to your skin—it's okay to take a break.
