Main Efficacy and Mechanism
Inhibition of Melanin Production
The calcium carbonate, amino acids, and trace elements in pearl powder may reduce melanin synthesis by inhibiting tyrosinase activity. Some studies indicate that the active ingredients in pearl powder can interfere with melanocyte differentiation, but the specific mechanism still requires further scientific verification.
Antioxidant Effect
The trace elements such as selenium and zinc, and natural antioxidants (such as pearl protein) in pearl powder can help eliminate free radicals and reduce oxidative damage to the skin caused by ultraviolet rays and environmental pollution, thereby delaying skin dullness.
Regulation of Skin Metabolism
The minerals and amino acids in pearl powder may promote epidermal cell renewal and accelerate the shedding of dead skin cells, making the skin smoother and brighter. Traditional Chinese medicine also believes that pearl powder has a "heat-clearing and yin-nourishing" effect, which may indirectly improve uneven skin tone caused by endocrine disorders.
