1.MECHANISM OF ACTION
Tyrosinase Inhibition: It directly binds to the active site of tyrosinase, the key enzyme in melanin production, reducing its catalytic activity by up to 40% in vitro.
Melanosome Transfer Suppression: The peptide downregulates the expression of proteins (e.g., Rab27a) responsible for transporting melanosomes from melanocytes to keratinocytes, limiting melanin deposition in the upper epidermis.
Anti-Inflammatory Regulation: It modulates cytokine release (e.g., IL-1α) triggered by UV exposure, preventing inflammation-induced melanin overproduction.
Antioxidant Activity: Scavenges reactive oxygen species (ROS) to protect skin cells from oxidative stress, a secondary driver of hyperpigmentation.
Hyperpigmentation: Fades age spots, sun spots, melasma, and post-inflammatory hyperpigmentation (PIH).
Skin Brightening: Evens skin tone and enhances radiance for a luminous, youthful complexion.
Anti-Aging: Reduces the appearance of dullness and uneven pigmentation associated with photoaging.
Post-Sun Repair: Mitigates UV-induced melanin synthesis to prevent darkening after sun exposure.
Sensitive Skin Care: Provides gentle brightening without irritation, suitable for reactive or post-procedure skin.
78% of participants showed a significant reduction in melanin index (measured via Mexameter) after 8 weeks, with further improvement at 12 weeks.
85% reported visibly brighter, more even skin tone in self-assessment questionnaires.
No adverse events (e.g., redness, dryness, irritation) were reported, confirming excellent tolerability.
