1. Alpha Arbutin
� Competitive inhibition of tyrosinase enzyme, which catalyzes conversion of tyrosine ? DOPA ? melanin.
� Reduces melanin biosynthesis in melanocytes without cytotoxicity.
� Acts as a controlled hydroquinone-releasing prodrug, providing depigmenting activity with better safety

2. Kojic Acid
� Chelates copper ions at the active site of tyrosinase, rendering the enzyme inactive.
� Suppresses melanin formation in melanocytes.
� Exhibits antioxidant activity, reducing oxidative pigmentation triggers

3. Asyntra SL (Hexylresorcinol Derivative / Skin Lightening Peptide Complex)
� Inhibits tyrosinase and TRP-1 (Tyrosinase Related Protein-1) involved in melanogenesis
� Downregulates MITF signaling pathway, reducing melanocyte activity
� Suppresses melanosome formation and maturation

4. Glycolic Acid
� Alpha-hydroxy acid that reduces corneocyte cohesion in the stratum corneum
� Accelerates epidermal turnover and desquamation
� Facilitates removal of melanin-laden keratinocytes from the epidermis

5. Tranexamic Acid
� Inhibits plasmin activity in keratinocytes ? decreases arachidonic acid and inflammatory mediators
� Suppresses UV-induced melanocyte activation
� Reduces melanocyte�keratinocyte interaction and melanosome transfer

6. Vitamin E (Tocopherol)
� Lipid-soluble antioxidant protecting cell membranes from lipid peroxidation
� Neutralizes reactive oxygen species (ROS) induced by UV radiation
� May inhibit tyrosinase activity indirectly by reducing oxidative stress

7. Niacinamide (Vitamin B3)
� Inhibits transfer of melanosomes from melanocytes to keratinocytes
� Improves epidermal barrier function by increasing ceramide synthesis
� Exhibits anti-inflammatory and antioxidant activity

8. Hyaluronic Acid
� High molecular weight glycosaminoglycan with strong water-binding capacity
� Forms hydration matrix in extracellular dermal space
� Enhances skin barrier integrity and wound healing

9. 4-Butylresorcinol
� Potent inhibitor of tyrosinase enzyme, blocking melanin synthesis
� Also inhibits tyrosinase-related protein-1 (TRP-1) involved in melanogenesis
� Exhibits stronger tyrosinase inhibition compared with kojic acid or arbutin
