The PCA Skin Vitamin B3 Brightening Serum 1 oz (30 ml) is a clinical-grade brightening treatment serum designed to improve uneven skin tone, reduce dark spots, and strengthen the skin barrier for a clearer, more radiant complexion.

It is powered by a high concentration of niacinamide (Vitamin B3) along with advanced skin-supporting ingredients that help target discoloration while also calming redness and improving overall skin quality.

✨ Key Benefits

• Helps fade dark spots and hyperpigmentation
• Improves uneven skin tone and dullness
• Strengthens the skin barrier function
• Helps reduce redness and irritation
• Improves overall skin brightness and clarity
• Supports smoother, healthier-looking skin over time

🔬 How It Works

This serum uses niacinamide (Vitamin B3) as its core active ingredient. It works by:

• Inhibiting excess melanin production (helps reduce pigmentation)
• Supporting the skin’s natural barrier to reduce sensitivity and redness
• Improving skin texture and preventing dull, “yellowed” appearance caused by oxidative stress

It also helps reduce glycation-related dullness, which contributes to aging and loss of radiance.

🧴 How to Use

1. Cleanse your skin thoroughly
2. Apply 3–5 drops to face, neck, and chest
3. Use once or twice daily (morning and/or evening)
4. Follow with moisturizer
5. Always apply SPF in the daytime for best results
