MelanoBronze Natural Tanning Activator
MelanoBronze Acetyl tyrosine Substrate for tyrosinase enzyme in melanin synthesis Vitex agnus-castus extract Induction of melanin synthesis in melanocytes
MelanoBronze MelanoBronze is a combination of two actives leading to an accelerated melanin formation in the skin Melanin is the body s own sun protecting system preventing sun burn and photo aging in the skin MelanoBronze stimulates skin tanning even without sun exposure

Mechanism of Skin Pigmentation α MSH MC1R camp tyrosinase tyrosin DOPA DOPA quinone DOPA chrom Cysteinyl DOPA melanocyte DHICA eumelanin pheomelanin
Acetyl Tyrosine Stable, water-soluble substrate for tyrosinase tyrosinase acetyl tyrosine DOPA melanin The reaction of tyrosine to DOPA by tyrosinase is the rate-limiting step in melanin formation. Result: tanned skin and increased UV self-protection of the skin

Beta-Endorphin and Pigmentation The beta-endorphin/μ-opiate receptor system is expressed in melanocytes and closely associated with melanosomes beta-endorphin μ-opiate receptor Melanocyte dendricity, proliferation and pigmentation are upregulated Kauser et al. 2003 Journal of Investigative Dermatology
Monk's Pepper Berries Contain Phyto-Endorphins Large shrub growing in mediterranean region and Asia Berries from Monk's pepper contain substances that bind to the opioid receptor (Phyto- Endorphins) Chaste tree (Vitex agnus-castus)
Monk s Pepper Berries Traditional Medicine Used since ancient Greek to treat injuries and inflammation In the middle ages, monks used dried berries. They probably experienced a sensation of well-beeing

MelanoBronze: Composition Vitex agnus-castus extract containing: Acetyl Tyrosine 6% Glycerin 20% Alcohol 20%
MelanoBronze Natural tanning induced by two mechanisms:
MelanoBronze MelanoBronze phyto-endorphin
MelanoBronze MelanoBronze phyto-endorphin acetyl tyrosine
MelanoBronze MelanoBronze phyto-endorphin acetyl tyrosine melanin
MelanoBronze for Pigmentation with Sun UV αmsh tyrosinase pigmentation UV+ MelanoBronze αmsh beta-endorphin activity tyrosinase + acetyl tyrosine pigmentation
MelanoBronze for Pigmentation without Sun MelanoBronze beta-endorphin activity tyrosinase + acetyl tyrosine pigmentation Acetyl Tyrosine no tyrosinase activity! + acetyl tyrosine no pigmentation!

MelanoBronze Protective Tanning Enhancer Claims MelanoBronze provides nice regular tanning by stimulating the natural melanin formation - with UV irradiation - without UV irradiation MelanoBronze leads to enhanced pigmentation and protects your skin against UV-induced damage.
Applications Daycreams MelanoBronze gives a natural tan and protects against photo-aging Sun protection products Sunscreens normally do prevent the formation of a rapid tanning MelanoBronze in sun protection products speeds up the tanning process Self tanning products MelanoBronze induces the skin's own melanin formation, enforcing your self tanning products
