This is a high-performance serum from Purito Seoul’s updated line. Since it contains a potent mix of Retinal, Tranexamic Acid (TXA), and Niacinamide, the description needs to highlight its "anti-aging" and "brightening" synergy while providing clear usage warnings for safety.

PURITO Seoul TXA 6 Niacinamide 10 Retinal Serum (30ml)

The Ultimate Overnight Resurfacing Treatment for Ageless, Radiant Skin

Unlock the power of clinical-grade ingredients with the Purito Seoul TXA 6 Niacinamide 10 Retinal Serum. This advanced nocturnal formula is designed to fast-track your journey to smoother, firmer, and more even-toned skin. By combining the gold standard of anti-aging (Retinal) with powerful brighteners, this serum tackles fine lines, stubborn dark spots, and enlarged pores simultaneously.

🚀 Powerhouse Ingredients

• 0.1% Retinal (Retinaldehyde): Works up to 11x faster than traditional Retinol. It accelerates cell turnover and boosts collagen to visibly reduce wrinkles and improve skin elasticity without the typical irritation.
• 6% Tranexamic Acid (TXA): A heavy-hitter for hyperpigmentation. It effectively interferes with melanin production to fade melasma, sun spots, and deep-rooted discoloration.
• 10% Niacinamide (Vitamin B3): High-concentration Niacinamide refines skin texture, regulates sebum production, and strengthens the moisture barrier to ensure the skin remains resilient.
• Centella Asiatica & Bakuchiol: Soothes the skin and provides a botanical boost to the anti-aging effects, making the potent formula more tolerable for sensitive skin.

✨ Key Benefits

• Dramatic Resurfacing: Smooths out rough texture and minimizes the appearance of deep wrinkles and fine lines.
• Intensive Brightening: The TXA-Niacinamide duo acts like a "dark spot eraser" for post-inflammatory hyperpigmentation (PIH).
• Pore Refinement: Clears congestion and tightens the pore structure for a "filtered" skin look.
• Youthful Firmness: Helps sagging skin regain its bounce and structural integrity.

📝 How to Use (PM Routine Only)

1. Phase In: Use 2–3 times a week at night to allow your skin to build tolerance. Gradually increase frequency to every night.
2. Apply: After cleansing and toning, apply a pea-sized amount over the face and neck.
3. Moisturize: Follow with a rich moisturizer to prevent dryness.
4. Sun Protection: Retinal increases sun sensitivity. You MUST apply a broad-spectrum SPF 50+ the following morning.
