Comprehensive Inhibition of Melanin Production
- undecylenol phenylalanine acts on various biochemical reactions involved in melanin formation triggered by α-MSH.
- undecylenol phenylalanine intercepts signals for melanin production and controls the binding of α-MSH to melanin-producing factors.
- This comprehensive inhibition leads to more effective and lasting skin whitening effects.
Competitive Binding to MC1-R Receptor:
- undecylenol phenylalanine is a structural analog of α-MSH (melanocyte-stimulating hormone).
- It can competitively bind to the melanocyte-stimulating hormone receptor MC1-R on melanocytes.
Inhibition of Tyrosinase Activity:
- By binding to MC1-R, undecylenol phenylalanine prevents the melanocytes from producing tyrosinase.
- Tyrosinase is a key enzyme in melanin synthesis, and its inhibition leads to reduced melanin production.
Reduction of Melanin Formation:
- The reduction in tyrosinase activity results in decreased melanin formation.
- This helps to reduce pigmentation and spots on the skin.

The uses of undecylenol phenylalanine can be summarized as follows:
- Cosmetic Applications:
- undecylenol phenylalanine, also known as Acxben or MoreWhite UP, acts as a melanocyte-stimulating hormone (α-MSH) receptor antagonist.
- It effectively inhibits the activity of tyrosinase and blocks the signal for melanin production, thereby inhibiting melanin formation at various stages.
- It is primarily used as a whitening agent in cosmetics, helping to reduce epidermal melanin deposition, improve skin tone, and address pigmentation issues such as post-inflammatory hyperpigmentation and age spots.
- Skin Care Benefits:
- It exhibits good skin affinity and can control the binding of α-MSH with melanin-generating factors, further blocking the melanin formation process.
- It can be formulated into stable, non-discoloring emulsions, creams, clear aqueous solutions, or gels for various skin care products.
- Combination with Other Ingredients:
- When combined with niacinamide, undecylenol phenylalanine can synergistically enhance skin whitening and spot-reducing effects.
- Niacinamide interferes with the melanin synthesis pathway by inhibiting the transfer of melanin to the stratum corneum and accelerating its metabolism.
In summary, undecylenol phenylalanine is primarily used as a whitening agent in cosmetics due to its ability to inhibit melanin formation. Its skin-friendly properties and compatibility with other ingredients make it a valuable addition to various skin care products.
