Description

BACKGROUND OF THE INVENTION

A. Field of the Invention

The present invention relates generally to treatment methods and compositions for improving the skin's visual appearance. In particular, the present invention is directed towards compositions and methods for their use comprising a combination of marine botanicals that can improve the skin's visual appearance by providing improvements in, for example, skin moisture, dryness, surface fine lines, wrinkles, firmness, and/or softness.

B. Background of the Invention

With chronological age, chronic exposure to adverse environmental factors, or malnutrition, the visual appearance, physical properties, and physiological functions of skin change in ways that are considered cosmetically undesirable. The most notable and obvious changes include the development of fine lines and wrinkles, loss of elasticity, increased sagging, loss of firmness, loss of color evenness or tone, coarse surface texture, and mottled pigmentation. Less obvious, but measurable changes which occur as skin ages or endures chronic environmental insult include a general reduction in cellular and tissue vitality, reduction in cell replication rates, reduced cutaneous blood flow, reduced moisture content, accumulated errors in structure and function, alterations in the normal regulation of common biochemical pathways, and a reduction in the skin's ability to remodel and repair itself. Many of the alterations in appearance and function of the skin are caused by changes in the outer epidermal layer of the skin, while others are caused by changes in the lower dermis.

Several different approaches can be used to treat damaged skin caused by aging, environmental factors, chemicals, or malnutrition. One approach involves the use of specific agents to directly stimulate or inhibit selected biochemical targets. Examples include the use of retinoids to stimulate collagen and glycosaminoglycan synthesis by fibroblasts (Schiltz, et al., 1986). Another approach is to use agents or processes that stimulate the rate at which the epidermis replaces itself, a process known as epidermal cell renewal. Increases in epidermal cell renewal rates usually result from a more rapid rate of replication of epidermal basal cells, and can be caused by diverse stimuli such as chemical or physical injury, adverse environmental conditions, or direct stimulators of basal cell division.

Some examples of chemical injury include allergic or non-allergic contact irritation, pH extremes, or interaction of the stratum corneum with household or industrial chemicals or pollutants. Physical injury can include skin abrasion, friction (i.e. on the soles and heels of the feet), or removal of the stratum corneum by physical exfoliation (i.e. cosmetic masks) or by tape stripping. Agents that directly or indirectly stimulate basal cell division include retinoids and barrier disrupters. For example, U.S. Pat. No. 5,720,963 discloses that a combination of hydroxy acids, retinoids, and cerebrosides causes chronic injury to the stratum corneum and results in epidermal and dermal repair of the structurally-deteriorated skin. U.S. Pat. No. 6,495,126, for example, uses a combination of surfactants and chelating agents to stimulate an endogenous stratum corneum chymotryptic proteinase that causes a loosening of corneocytes, resulting in an increased rate of epidermal replacement and chronic anti-aging benefits. Adverse environmental exposures that can result in more rapid epidermal turnover rates include UVA, UVB, and IR radiation from the sun and cold coupled with low relative humidity (i.e. low dew point).

Several methods of increasing stratum corneum renewal rates have various drawbacks, such as significant irritation to the skin, skin toxicity, or low pH. In addition, most of these methods involve the invocation of chronic damage to the skin, which sets up repair mechanisms. For most of the existing treatments, there will be a period of time, up to several weeks or months, during which the skin becomes irritated and after which tolerance sets in and the symptoms of irritation may decrease and/or cease.

Chronic Anti Aging Study

Materials and Methods:

The following study was conducted to determine if a marine composition comprising 5.0% CODIAVELANE®, 1.0% AOSAINE®, 2.0% Monostroma, 5.0% OLEAPHYCOL-CM®, and 3.0% CHLORELLINE® (a non-limiting example of a botanical blend of the present invention) provides long-term visual and measurable anti-aging benefits on the human face. Vehicle A (Table 1) was used as a control. Twenty panelists applied the composition twice a day, morning and evening on their face.

*Procedure to make Vehicle A: Add the ingredients in A to vessel, in order, at room temperature, mixing between additions. Begin heating to 75° C. At 50° C., add B. At 75° C. add C, in order, mixing between additions. As mixture cools, add D at 65° C. At 45° C., add E and F.

The panelists were monitored for skin condition at the beginning of the study (i.e. before treatment); at four weeks after the treatment; and at eight weeks after the treatment. They were evaluated for face and neck moisture, dryness, surface fine lines, canthus wrinkles, firmness, softness, and clarity. The results identified in Table 2 were obtained by using the following procedures. Face and neck moisture were evaluated using impedance measurements, an electrical conductivity measurement using the Nova Dermal Phase Meter. Dryness, surface fine lines, and softness were determined by an expert grader using a calibrated visual analog scale from 1 to 10. Skin softness was measured by Gas Bearing Electrodynamometer. Surface fine lines were counted and the severity of the lines evaluated according to the Packman-Gans method, (1978), using weighted scoring. Dryness was evaluated using a calibrated visual analog scale from 1 to 10. Firmness was evaluated using a Hargens ballistometer, a device that evaluates the elasticity and firmness of the skin by dropping a small body onto the skin and recording its first two rebound peaks. As firmness decreases, the second peak will be smaller in comparison to the first. Clarity was evaluated using a Minolta Chromameter, which measures the total light reflected from the skin compared to the amount of red and brown/yellow light. These measurements were mathematically analyzed to determine the clarity of the skin. Canthus wrinkles were evaluated four and eight weeks after treatment by comparing the silicone replicas (negative impressions) made of the individuals' skin at baseline. The replicas were evaluated by computer image analysis to determine the number and depth of the wrinkles.

Results:

As shown in Tables 2 and 3, continued improvement was seen for the skin condition parameters throughout the 8 weeks of the study. The composition comprising the marine botanicals performed better than the vehicle A control. A continued improvement was also seen with vehicle A. This was due to the moisturizing ingredients in the vehicle A formula.

*Fifteen panelists in each of the treatment cells participated in the study. After 2, 4, and 8 weeks of product use, the panelists rated their skin condition on a 5-point scale which compared the condition at the start of the study. The scale ranged from the assessed parameter being much less improved, somewhat less improved, no change, somewhat greater improved, and much greater improved. The values represent the percent of panelists who perceived greater improvement at the given point in time. A person of ordinary skill in cosmetic arts understand the meaning of the terms used in the far left column of Table 3.

Example 2

Stratum Corneum Turnover Study

Materials and Methods:

The following procedure was utilized to estimate stratum corneum turnover rates on human skin, which results directly from epidermal activation. Four sites were marked on the forearm using a plastic template. Baseline readings of color intensity were determined using a Minolta Chromameter (b* value listed in Table 4). Occlusive Hilltop chambers (2 cm diameter) containing 0.05 ml Mary Kay SUN ESSENTIALS® Sunless Tanning Lotion product with dihydroxyacetone (DHA) were placed on the sites. After 6 hours, these patches were removed, and 18 hours later, the color intensity was again determined using the Chromameter. The A b* values in Table 4 were calculated as the difference between the reading and the baseline. Panelists applied the formula in Table 5 to the brown spots in the morning and evening during the ensuing 10 days. Chromameter readings were repeated after 4, 7, and, 10 days. The color decay slope was calculated as the percent loss per day, and the transit time determined by extrapolating to 100% loss of color.

Results:

The results of this study (Table 4) indicate that the combination of Sea Fennel, Monostroma, and CHLORELLINE® increased the rate at which the stratum corneum replaced itself when compared to the vehicle B (Table 5) that was used to incorporate these three ingredients. The effects were concentration-dependent. The increases in stratum corneum replacement rate show that Sea Fennel, Monostroma, and CHLORELLINE® in the composition activate and/or stimulate the epidermis of the skin.
