present application by reference.
BACKGROUND OF THE INVENTION
A. Field of the Invention
[0002] The present invention relates generally to compositions that
can be used to improve the skin's visual appearance. In certain
aspects, the compositions of the present invention can include, for
example, a combination of ingredients to whiten skin, even out skin
color, or treat hyperpigmentation. This combination of ingredients
can be included in a wide-range of product formulations (e.g.,
serums, eye creams, toners, gels, masks, etc.).
B. Description of Related Art
[0003] The color in human skin is caused by the pigment melanin.
Melanin is produced in special dendritic cells, melanocytes, which
are found below or between the basal cells of the epidermis of the
skin (U.S. Pat. No. 5,411,741). When exposed to damaging
environmental factors such the ultra violet (UV) radiation of the
sun, irritants, and pollution, the keratinocyte (outermost cell of
the skin) releases signaling molecules, such as
.alpha.-melanocyte-stimulating hormone (.alpha.-MSH), and
inflammatory cytokines. These hormones trigger melanocytes to
produce melanin (Garcia-Borron et al., 2005).
[0004] Typical pigmentation is characterized by an even, uniform
coloration of the skin. Many individuals have excess melanin
pigmentation or a hyperpigmentation patch which can cause
pigmentary variation or abnormal pigmentation of the skin. This may
lead to unwanted freckles or dark spots such as senile lentigo,
liver spots, melasma, brown or age spots, vitiligo, sunburn
pigmentation, post-inflammatory hyperpigmentation due to abrasion,
burns, wounds or dermatitis, phototoxic reaction and other similar
small, fixed pigmented lesions. It is often desirable to lighten
these areas or even out the appearance of irregularly pigmented
areas of skin. Individuals may also wish to increase fairness or
reduce the overall level of pigmentation in the skin. In either
case, the hyperpigmentation is usually viewed as cosmetically
undesirable and individuals often wish to lighten the skin.
[0005] In some instances, the use of one skin lightening ingredient
may not be effective for individuals with significant
hyperpigmentation, freckles, or age spots, for example.
Additionally, previous attempts to combine various skin lightening
ingredients have been ineffective, and in some instance, have
produced negative results (Talwar 1993).
SUMMARY OF THE INVENTION
[0006] The present invention overcomes deficiencies in the art by
providing an effective and natural alternative to lighten skin,
reduce the appearance of uneven skin tone, and/or treat melasmic
skin. The solution is premised on a discovery of a combination of
ingredients--Leontopodium alpinum extract, Halidrys siliquosa
extract, vegetable amino acids, niacinamide, hexylresorcinol, Pinus
pinaster extract, Betula alba extract, Albizia julibrissin bark
extract, hydrolyzed Candida saitoana extract, Lentinus edodes
mycelium extract, and/or Opuntia tuna fruit extract--that can be
used for improving the skin's visual appearance, whitening or
lightening the skin's color or tone, treating hyperpigmentation and
other related disorders, and evening out a person's skin tone. This
combination of ingredients can be used in a variety of product
formulations (e.g., toners, cleansers, emulsions such as lotions or
creams, masks, gels, etc.).
[0007] In one instance, there is disclosed a topical skin
composition comprising an effective amount of a combination of
Leontopodium alpinum extract, Halidrys siliquosa extract, vegetable
amino acids, and niacinamide. Alternatively, one or any combination

DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS
[0041] Melanocytes are found in the basal layer of the epidermis.
When exposed to damaging environmental factors such the ultra
violet (UV) radiation of the sun, irritants, and pollution, the
keratinocyte (outermost cell of the skin) releases signaling
molecules, such as .alpha.-melanocyte-stimulating hormone
(.alpha.-MSH), and inflammatory cytokines. These hormones trigger
melanocytes to produce pigment known as melanin (Garcia-Borron et
al., 2005). Tyrosine is a precursor molecule to melanin synthesis.
It requires the enzyme tyrosinase (TYR) to change tyrosine into
melanin. This reaction occurs in the melanosome, as it becomes
fully matured it is filled with melanin. (Goldsmith, 1991). During
this maturation process, glutathione (GSH) influences the type of
melanin produced. GSH, while mostly known for its detoxification
function, also shifts the production of eumelanin (dark) to
pheomelanin (light). Melanocytes have dendrite structures that
transfer melanosomes to the keratinocyte. (Seiberg, 2001). Damage
from prolong exposure to UV rays, free radicals and irritants lead
to excessive production of melanin by the melanocyte. This
unregulated production of melanin leads to dark spot formation, and
uneven skin tone (Bastiaens et al, 2004).
[0042] The compositions and methods of the present invention can be
used, for example, for improving the skin's visual appearance,
whitening or lightening the skin's color or tone, treating
hyperpigmentation and other related disorders, and evening out a
person's skin tone. In certain embodiments, the compositions of the
present invention can include a combination of ingredients that can
be used to lighten or whiten skin. These and other non-limiting
aspects of the present invention are discussed in further detail in
the following sections.
[0043] These and other non-limiting aspects of the present
invention are provided in the following subsections.
A. Combination of Ingredients
[0044] The present invention is premised on a discovery of a
combination of ingredients--Leontopodium alpinum extract, Halidrys
siliquosa extract, vegetable amino acids, niacinamide,
hexylresorcinol, Pinus pinaster extract, Betula alba extract,
Albizia julibrissin bark extract, hydrolyzed Candida saitoana
extract, Lentinus edodes mycelium extract, and/or Opuntia tuna
fruit extract--that can be used to improve the skin's visual
appearance, whiten or lighten the skin's color or tone, treat
hyperpigmentation and other related disorders, and even out a
person's skin tone. These ingredients are discussed in more detail
below.
[0045] Leontopodium alpinum extract: Also known as edelweiss,
Leontopodium alpinum is native to remote mountain areas such as the
Alps. This ingredient is commercially available from a variety of
sources (see, e.g., CTFA, Volume 2, page 1449, which is
incorporated by reference). An exemplary source can be obtained
from Carrubba Inc. (Milford, Conn. USA) under the trade name
Edelweiss Extract M5768. It has been discovered that this
ingredient can be used to reduce the production of melanin in skin
cells (See Example 1).
[0046] Halidrys siliquosa extract: Native to the British Isles and
Europe, the extract is a skin conditioner. This ingredient is
commercially available from a variety of sources. An exemplary
source can be obtained from Biosil (FRANCE) under the trade name
Lightoceane.RTM.. It has been discovered that this algae extract
targets melanin production and helps inhibit the appearance of
melanin on the skin's surface by reducing the transfer of melanin
to the skin (See Example 1).
[0047] Vegetable amino acids (navy bean): The navy bean is produced
from the common bean plant (Phaseolus vulgaris). The navy bean is a
small white bean that is produced worldwide from North America to
Europe to Africa to Asia, and it is different from green beans,
anasazi beans, black beans, cranberry or borlotti beans, chickpeas,
lentil beans, pink beans, pinto beans, red kidney beans, shell
beans, and yellow beans. Vegetable amino acids (navy bean) have
been discovered to significantly improve the brightness of the
skin. They have also been shown to improve the overall evenness of
skin tone and reduce the visible contrast of dark spots on the skin
as it targets melanin production (See Examples 1 and 2). Navy bean
extract is commercially available from a wide range of sources. For
instance, Carrubba Inc. (Milford, Conn. USA) produces an aqueous
liquid navy bean extract that can be used in the context of the
present invention. Also, InfraReady Products (1998) Ltd. (CANADA)
produces a powdered navy been extract that can also be used in the
context of the present invention.
[0048] Niacinamide: Also known nicotinamide, 3-Pyridinecarboxamide,
or Vitamin B.sub.3, it is an organic compound known to exhibit skin
conditioning benefits when used in cosmetic compositions.
Niacinamide has the following chemical formula:
##STR00001##
[0049] This ingredient is commercially available from a variety of
sources (see, e.g., CTFA, Volume 2, pages 1651-1652, which is
incorporated by reference). It has been discovered that this
ingredient can be used to provide added skin brightening benefits
and to inhibit melanin transfer to the skin (See Example 1).
[0050] Hexylresorcinol: Glutathione (GSH), comprised of three amino
acids, is vital to the skin's detoxification process. As we age,
our body's natural production of GSH decreases. Stress and
environmental pollutants also depletes its levels. GSH can also
influence the melanocyte to produce lighter melanin.
Hexylresorcinol is shown to boost glutathione in skin. It is also
shown to target melanin production and help prevent protein
glycation. Accumulation of glycated proteins in skin can lead to
discoloration, in addition to damaging the skin. (See Example 1).
This ingredient is commercially available from a variety of sources
(see, e.g., CTFA, Volume 1, page 1158, which is incorporated by
reference). An exemplary source can be obtained from Syntheon
Limited (USA) under the trade name Synovea.RTM. HR.
[0051] Pinus pinaster bark/bud extract: Native to the
Mediterranean, the Maritime Pine is a known source of antioxidants
such as flavonoids, catechins, proanthocyanidins, and phenolic
acids. This ingredient is commercially available from a variety of
sources (see, e.g., CTFA, Volume 2, page 2034, which is
incorporated by reference). An exemplary source can be obtained
from Carrubba Inc. (Milford, Conn. USA). It has been discovered
that this ingredient can be used to reduce the production of
melanin in skin cells (See Example 1).
[0052] Betula alba leaf extract: Native to Northern Europe, and
Iceland, the extract of the White Birch is known for its purifying
and detoxifying effects, encourages the excretion of fluids and
promotes metabolic activities. This ingredient is commercially
available from a variety of sources (see, e.g., CTFA, Volume 1,
page 280, which is incorporated by reference). An exemplary source
can be obtained from Carrubba Inc. (Milford, Conn. USA). It has
been discovered that this ingredient can be used to reduce the
production of melanin in skin cells (See Example 1).
[0053] Albizia julibrissin bark extract: Also known as the Persian
or pink silk tree, Albizia julibrissin is native to southwestern
and eastern Asia. This ingredient is commercially available from a
variety of sources (see, e.g., CTFA, Volume 1, page 84, which is
incorporated by reference). An exemplary source can be obtained
from Sederma (FRANCE) under the trade name Prodizia.TM..
[0054] Hydrolyzed Candida saitoana extract: An isolated and
purified form of Candida saitoana, a fungi obtained from a
fermentation process, the extract is designed to target proteasome
and autophagic pathways, the skin's natural detoxification
mechanisms. This ingredient is commercially available from a
variety of sources. An exemplary source can be obtained from Silab
(FRANCE) under the trade name Celldetox.RTM..
[0055] Lentinus edodes mycelium extract: Also known as Lentinus
enodes and shiitake, Lentinus edodes mycelium is a wood-decaying
basidiomycetes growing on fallen wood of a wide variety of
deciduous trees throughout east Asia and as far south as Australia.
It is capable of providing antioxidant and anti-inflammatory
benefit for skin. It is also a source of kojic acid, which is
beneficial to even and lighten skin tone. This ingredient is
commercially available from a variety of sources. An exemplary

Efficacy of Ingredients
[0093] Leontopodium alpinum extract, Halidrys siliquosa extract,
vegetable amino acid (navy bean), Pinus pinaster extract, and
Betula alba extract have been shown to inhibit B16 melanogenesis
using a bioassay that analyzes the effect of compounds on B16
melanogenesis. The endpoint of this assay is a spectrophotometric
measurement of melanin production and cellular viability. A summary
of these data are provided in Table 1.
TABLE-US-00001 TABLE 1* Ingredient* % inhibition** Leontopodium
alpinum extract (1%) -43.75 Halidrys siliquosa extract (1%)

Betula alba extract (1%) -47.47 *Each ingredient was obtained from
the following suppliers: Leontopodium alpinum extract was obtained
from Carrubba Inc. under the trade name Edelweiss Extract M5768.
Halidrys siliquosa extract was obtained from Biosil under the trade
name Lightoceane .RTM.. Navy bean was obtained from Carrubba Inc.
Pinus pinaster extract was obtained from Carrabba Inc. Betula alba
extract was obtained from Carrubba Inc. **Control used was Kojic
Acid 10 mM. % inhibition is calculated = (pigment levels after 3
days treated-pigment level after 3 days of untreated control)
0)/pigment level after 3days of untreated control) X100%).
Therefore, a negative (-) indicates inhibition of
melanogenesis.
[0094] The procedure used to obtain the data in Table 1 included
the following steps: [0095] Grow B16 cells to subconfluence from a
frozen vial in T150 tissue culture flasks. Trypsinize 1 confluent
T150 and resuspend in DMEM. Seed 1% of cells in each 96 well plate
(200 ul total volume). Dilute test compounds to 1% in media. Once
cells reach .about.20% confluence, replace media with 200 ul
diluted compounds. Treat 2 wells/group. If a positive control is
utilized, treat cells with 1 mM Kojic acid. Incubate cells for 5-6
days (37.degree. C., 10% CO2). Read plate at 405 nm. Remove all
media from cells. Add 100 ul diluted MTS reagent. Incubate 15-30
min (37.degree. C., 10% CO2). Read plate at 490 nm.
[0096] Halidrys siliquosa extract was found to have significant
effects inhibiting transfer of melanosomes using an in vitro assay
that analyzes the effect of test articles on the mechanism of
melanosome transfer. Melanosome transfer is the process by which
melanocytes deliver melanin to keratinocytes. Melanocytes
synthesize approximately 0.5 .mu.m melanin-containing vesicles
called melanosomes which are phagocytosed by keratinocytes. This
bioassay mimics this process by incubating keratinocytes with
fluorescent microspheres of similar size to melanosomes. Inhibition
or promotion of microsphere uptake is correlated with uptake of
normal melanosomes which is a critical process for skin
pigmentation. A summary of these data are provided in Table 2.

melanosome transfer.
[0097] The procedure used to obtain the data in Table 2 included
the following steps: [0098] Grow HEKa cells to subconfluence from a
frozen vial in 3.times.T75 tissue culture flasks (37.degree. C., 5%
CO2). Wash confluent T75s (P1-P3) with HBSS then trypsinize with
1.5 ml trypsin for .about.4 min at 37.degree. C. Collect cells in 4
ml TNS, then spin in 15 ml conical tubes. Resuspend in Epilife
media and plate in black 96 well plate. Dilute test compounds to
appropriate concentration in sterile water. Upon reaching 85%
confluence replace media with 200 ml media with 20 ul diluted test
compound overnight (37.degree. C., 5% CO2). Remove media and add
replace with microsphere dilution. Re-add diluted test material.
Incubate overnight (37.degree. C., 5% CO2). Wash cells 4 times with
PBS. Add 100 ul PBS per well. Read Ex/Em at 480/520 on BioTek
FLx800 fluorometric plate reader. Set threshold sensitivity at 65.
Remove PBS and replace with 100 ul diluted MTS reagent to each
well. Incubate 15-30 min (37.degree. C., 5% CO2). Read plate at 490
nm.
[0099] Hexylresorcinol was found to have significant effects
inhibiting glycation of ribose to BSA using a ribose/BSA glycation
assay. A summary of these data are provided in Table 3.

In Vitro Data
[0102] Hyperpigmentation in skin is caused by an increase in
melanin, the substance in the body that is responsible for color
(pigment). It is characterized by age spots, dark spots and patches
of pigmentation. Vegetable amino acid (aka Navy bean) which is one
of the active ingredients in this formula has been suggested to
have skin brightening benefits based on in vitro testing. The
inventors evaluated the effects of vegetable amino acid as a key
ingredient on hyperpigmentation.
[0103] The "treated" group applied Moisturizer comprising a
proprietary base lotion formulation having no preservatives ("Vinny
Base") with 1% vegetable amino acid at least twice a day in the
morning and at night, while the "untreated" group applied
Moisturizer without 1% vegetable amino acid at least twice a day in
the morning and at night.
[0104] Study design: 12 week randomized, single blind study. Sample
size of treatment group was 21 panelists, sample size of untreated
group (control) was 9 panelists. The panelists were screened for
melasma, age spots and dark spots. Visual grading was done at Day 0
and Weeks 4, 8, and 12 by Hanh Pham. Facial photographs were taken
at Day 0 and Weeks 4, 8, and 12 using Clarity Pro. Each panelist
was asked to use the test product as the only facial product for 12
weeks. Basic Moisturizer and SPF 30 Sunscreen were provided, each
of which comprised a Vinny Base (i.e., a proprietary base lotion
formulation having no preservatives).
Visual Grading
[0105] The parameters used included: [0106] Uneven Skin Tone:
Assessment of the overall uniformity of skin color (inclusive of
both pigment & blotchiness). [0107] Discrete Pigment: Distinct
uniform areas of darker pigment, for instance "age" or brown spots;
freckles. [0108] Mottled Pigment: Dark blotches that were larger
and more irregular in size and shape than discrete pigmentation.
These areas tend to become darker with sun exposure. [0109] Scale:
Global Photo aging Scale (0 to 9), where None (0), Mild (1,2,3),
Moderate (4,5,6), and Severe (7,8,9).
[0110] Instrumental Evaluation: The Clarity.TM. Pro Advanced Skin
Advisor System was used. The Clarity.TM. Pro is an imaging system
with multispectral lighting for surface and sub-surface skin
analysis. This imaging system utilizes patented facial recognition
technology to analyze various skin features such as pigmentation,
wrinkles, redness and acne. Clarity.TM. Pro was purchased in from
BTBP Inc. The Pigmentation feature was utilized to analyze the
images in this study. This features comprises of Brightness
intensity, Pigmentation contrast and Pigmentation variation. Full
face photographs were captured--frontal and 45.degree. lateral
images (left and right) in multispectral lighting. Images were
analyzed for Brightness intensity, Pigment variation and Pigment
contrast. VISIA-CR Canfield Imaging System was used as a backup,
and full face photographs captured--frontal images were captured
only in standard and cross polarized lighting. Images visually
assessed for improvement in skin pigmentation.
