Allantoin Powder is a high-purity crystalline active and a mechanical necessity for barrier repair and calming skin distress. This water-soluble powder (usage rate: 0.1%–2.0%) is essential for helping the skin renew itself without the irritation caused by harsher ingredients, making it a reliable choice for reactive or melanin-rich skin. According to clinical studies on Allantoin, it acts as a verified skin protectant by significantly reducing the signals that trigger redness and heat, while remaining stable within a pH range of 4.0–6.5 in professional mixtures.
