Solves the fatal flaws of traditional Kojic Acid — sensitive to light and heat and prone to discoloration.
Mechanism: The active hydroxyl group is esterified and blocked by palmitic acid, making it highly stable against light, heat, oxygen, and metal ions.
Data: In accelerated testing (45°C / 60% RH for 3 months), the active retention rate is >90% (vs. only 58% for Kojic Acid).
Benefit: Resists yellowing and loss of efficacy in formulations without requiring large amounts of additional stabilizers.
Tyrosinase Inhibition: Chelates copper ions (Cu²⁺) at the enzyme's active center, strongly blocking the key rate-limiting step of melanin synthesis. Inhibition efficiency is superior to Kojic Acid and Arbutin.
Blocking Melanin Production: Reduces the formation of spots and dullness from the source, with an efficacy rate exceeding 80%.
Gentle Brightening: Also offers antioxidant benefits, improving uneven skin tone and aging-related dullness.
Structure: Lipid-soluble structure reduces skin penetration irritation, eliminating the burning sensation of traditional Kojic Acid.
Patch Test: At 2% concentration, causes no irritation to healthy skin. Irritation index for sensitive skin is only 0.8 (vs. 2.3 for Kojic Acid).
Usage: Non-photosensitive, safe for daytime use, no risk of rebound hyperpigmentation.
Solubility: Being lipid-soluble, it easily integrates into oil-phase systems like creams and lotions.
Compatibility: Does not conflict with most preservatives, sunscreens, vitamins, and plant extracts.
Penetration: Strong penetration power, effectively reaching skin targets.
