Appearance: White crystalline powder, odorless.
Solubility: Easily soluble in water and ethanol; water solubility is better than nicotinic acid.
Stability: Relatively stable under acidic, alkaline, and thermal conditions.
Whitening and Brightening: Inhibits the transfer of melanin to the stratum corneum (not inhibits its production), reduces pigmentation, and brightens skin tone.
Barrier Repair: Promotes ceramide synthesis, strengthens the skin barrier, and reduces moisture loss (locks in moisture).
Oil Control and Acne Prevention: A 2% concentration can reduce sebum secretion by approximately 20%, improving oily skin, enlarged pores, and inflammatory acne.
Anti-aging and Firming: Stimulates collagen production, reduces fine lines and wrinkles, and provides antioxidant and anti-photoaging benefits.
Anti-inflammatory and Soothing: Relieves sensitivity and redness, and helps improve rosacea and seborrheic dermatitis.
