EXPLANATIONS
Niacinamide 10%
(Vitamin B3) Helps prevent photo-immunosuppression caused by
UVR.
Inhibits melanosome transfer to the keratinocytes. Also assists down-regulation
of sebum production.
Ascorbyl
Glucoside 2%
(Ascorbic Acid 2-Glucoside)
Promotes synthesis of collagen by fibroblasts.
Reduces fine lines and wrinkles.
Helps suppress melanin synthesis.
Undecylenoyl phenylalanine 0.5%
(UCPA)
Melanotropin inhibitor (_ MSH antagonist). Competes with melanotropin
at the MC1R receptor on the melanocyte, thus inhibiting melanogenesis.
Palmitoyl
Pentapeptide-3 Stimulates fibroblasts to produce collagen and
elastin, resulting in reduction of the appearance of wrinkles
Sodium Hyaluronate Increases
hydration in upper epidermis.
KNOWN CONTRAINDICATIONS/PRECAUTIONS
Pregnancy There is insufficient data about the safety of this
product during pregnancy. Patients should be made aware of this at time of consultation.
Phenylketonurics This product contains phenylalanine which
cannot be metabolised by PKUs and should be avoided by these patients.
STUDIES
NIACINAMIDE
In vivo studies indicate that topical niacinamide prevents photo-immunosuppression
related to UVR exposure. A reduction in subsequent tumor incidence has also been
reported.
In vitro and in vivo studies suggest that niacinamide may successfully
inhibit melanosome transfer from the melanocyte to the keratinocyte, resulting
in reduction of melanotic hyperpigmented lesions. In certain in vitro models,
niacinamide achieved a 35-68% inhibition of melanosome transfer. In clinical
studies of 120 women over 4 weeks, niacinamide was shown to significantly reduce
epidermal hypermelanosis.
ASCORBYL GLUCOSIDE
Ascorbyl glucoside shows analogous clinical effects to vitamin C when applied
topically. This is due to the degradation of the glucoside component of the molecule
in the skin by ±-glucosidase, leaving vitamin C. Ascorbyl glucoside demonstrates
stimulation of collagen synthesis, as well as free radical scavenging properties.
In vitro studies with cultured cells also show the ability of ascorbyl glucoside
to suppress melanin production.
UNDECYLENOYL PHENYLALANINE
Research in vitro indicates that UCPA inhibits melanogenesis by acting as an
_ -MSH antagonist, suppressing the melanotropin cascade, resulting in decreased
tyrosinase synthesis.
PALMITOYL PENTAPEPTIDE-3
The amino acid sequence lysine-theronine-theronine-lysine-serine has been found
to positively affect feedback regulation of collagen synthesis when applied topically.
