Side Effects of Face Facts Niacinamide Serum

• Common: A mild, temporary tingling or flushing sensation when first introduced to your routine.
• Rare: Localized skin irritation, micro-comedones (if your skin is highly sensitive to the specific base formulation), or itching.
• Action: If persistent irritation or a rash occurs, wash the product away with cool water and consult a pharmacist.

Precautions and Warnings

• Sun Protection: While Niacinamide does not increase sun sensitivity, you should always wear a daily broad-spectrum sunscreen ($\text{SPF } 30+$) to preserve an even skin tone.
• Product Layering: If you are using a high-strength pure Ascorbic Acid (Vitamin C) product, it is ideal to use them at different times of the day (e.g., Vitamin C in the morning and Niacinamide at night) to prevent temporary skin flushing.
• Patch Testing: Always apply 2–3 drops to a small area on your jawline for 24 hours to rule out a localized sensitivity reaction.
