Patent Application
20230180915
The present disclosure relates to methods of tanning the skin of a person, and articles therefor. In particular, tanning is accomplished using a sunless tanning solution.
It is widely known that tanning by exposure to the sun's radiation, while effective, has notable health risks. Excessive exposure to the sun can not only cause sunburn, but over time can permanently damage the skin and raise the risk of cancer. Despite those risks, people continue to demand the aesthetic appeal of tanned skin.
Sunless tanning has become increasingly popular as a way to achieve a tanned appearance without the risks associated with tanning by sun exposure (or artificial radiation). One of several chemical compounds is provided in solution and applied to the skin, and reacts with the skin to cause temporary darkening of the skin. Sunless tanning solution is often applied via spray, such as an packaged aerosol, or in the context of a tanning salon, spray booths are often used. In addition, tanning solution may be applied manually by a technician via air brushing. Air brushing is considered by some to be the most natural-looking, aesthetically pleasing tan, mimicking the results from natural tanning via the sun or artificial radiation. However, airbrushing creates a mist that both the customer and the technician breathe in during application, raising health concerns.
One protocol for sunless tanning is described here: https://chocolatesun.com/pages/the-session.
Additional drawbacks associated with spray-based sunless tanning approach include durability, uniformity, color and tone, drying time, skin prep prior to application, and overall feel. Sunless tanning products can often show streaks or blotches, have a non-natural color, have a sticky feel, and can wear off due to sweat or abrasion or the like. As the pigment wears off, sometimes it can come off non-uniformly, creating an even less natural look over the days following treatment.
Other approaches use a tanning lotion, oftentimes having the consistency of skin lotions, which are not suitable for spraying. One product is packaged with an integral roller and can be rolled onto the skin. However, such products tend to perform poorly, with only modest darkening of the skin and unevenness.
A need continues to exist in the industry for improved sunless tanning techniques and products.
The following discussion will focus on specific implementations and embodiments of the teachings. The detailed description is provided to assist in describing certain embodiments and should not be interpreted as a limitation on the scope or applicability of the disclosure or teachings. It will be appreciated that other embodiments can be used based on the disclosure and teachings as provided herein.
The terms “comprises,” “comprising,” “includes,” “including,” “has,” “having” or any other variation thereof, are intended to cover a non-exclusive inclusion. For example, a method, article, or apparatus that comprises a list of features is not necessarily limited only to those features but may include other features not expressly listed or inherent to such method, article, or apparatus. Further, unless expressly stated to the contrary, “or” refers to an inclusive-or and not to an exclusive-or. For example, a condition A or B is satisfied by any one of the following: A is true (or present) and B is false (or not present), A is false (or not present) and B is true (or present), and both A and B are true (or present).
Also, the use of “a” or “an” is employed to describe elements and components described herein. This is done merely for convenience and to give a general sense of the scope of the invention. This description should be read to include one, at least one, or the singular as also including the plural, or vice versa, unless it is clear that it is meant otherwise. For example, when a single item is described herein, more than one item may be used in place of a single item. Similarly, where more than one item is described herein, a single item may be substituted for that more than one item.
According to an aspect, a method of tanning the skin of a person is provided. Here, tanning is carried out by contacting an applicator to the skin. Applicators come in various forms, including sponges, brushes, rollers, etc. An applicator has the functionality to absorb or hold tanning solution and apply the tanning solution to the skin by contact of the applicator to the skin. In one particular aspect, the applicator is a roller. The roller can have a nap, formed of fibers. Fibers can be natural or synthetic and in one embodiment, the fibers are natural mohair. In an embodiment, the roller is sized so as to be easily maneuverable on the skin around and along contours of the body. The roller may be 1″ to 9″ in length, and in one embodiment, the roller can have a length within a range of 2″ to 4.5″.
Prior to contact with the skin, the applicator can be exposed to a tanning formulation, or tanning solution, or moisturizer, or a combination thereof. Tanning solutions generally contain an active tanning agent in liquid base. Active tanning agents include Dihydroxyacetone (DHA), which functions to darken at least the outer skin layer of a person through a chemical reaction with the skin, such as by Maillard reaction. Other tanning agents may be used. In addition, the tanning solution may contain other ingredients such as moisturizing species and bronzers. Bronzers can be helpful to track the area of application of the product and the concentration of the product. However, in other embodiments, the tanning solution can be bronzer free.
Moisturizers contain one or several moisturizing species. The moisturizer functions to increase hydration of the skin by reducing evaporation. Moisturizing species include at least one component from the group consisting of skin lipids, skin sterols, oils, humectants, emollients or lubricants. In one embodiment, the moisturizer is free of DHA, and can be free of active tanning agents.
Tanning formulations contain a combination of a tanning agent and a moisturizing species. Tanning formulations may contain a combination of a tanning solution and moisturizer, provided that it contains both a tanning agent and a moisturizing species.
In one particular embodiment, a tanning solution is applied to the applicator, and separately, a moisturizer is applied to the applicator. The moisturizer can be applied first to the applicator, and in the case of a roller, it can partially or full saturate the roller. In the case of first applying the moisturizer, tanning solution is then applied to the roller. Application can be made directly to the roller such as by dispensing product directly onto the roller, or product can be applied to a tray (e.g., paint tray) and the product absorbed into the roller by rolling along a surface of the tray much in the same way paint is applied to a roller in case of painting surfaces. The roller generally includes a roller frame and a roller cover. The roller cover is generally cylindrical and slips onto the roller frame that allows the roller cover to rotate on is longitudinal axis.
Once moisturizer and tanning solution is applied to the applicator, the applicator is brought into contact with skin of a person thereby coating the skin with the combination of tanning solution and moisturizer. During the tanning of a person, the relative proportions of tanning solution and moisturizer can be modified. This can be accomplished by changing the amount of products applied to the roller prior to application to the skin. Changing ratios of tanning solution to moisturizer during tanning can be done to accommodate localized oily, normal or dry areas of the skin. For example, it may be desirable to apply higher concentrations of moisturizer to areas of the skin that are dry, and conversely, lower concentrations of moisturizer to normal to oily areas of skin. The technician applying the products can modify relative proportions of based on observation of product behavior on the skin (e.g., speed of drying) as well as observations of skin condition (dry, normal, oily), for example.
The moisturizer and the tanning solution can be applied separately, such as dispensed from separate containers and onto the applicator. The tanning solution and the moisturizer may be deployed onto the applicator in a range of weight ratios, such as at a weight ratio from 1:1 to 50:1, such as 2:1 to 25:1, such as 2:1 to 15:1.
According to another embodiment, a tanning technique includes contacting an applicator to apply tanning solution and moisturizer to the skin of a person, and contacting a sponge to the skin to blend the applied tanning solution and moisturizer. In this particular embodiment, attention is drawn to use of a sponge to blend the applied products into and/or along the skin of a person. The sponge may be naturally occurring or synthetic and is generally formed of a compressible material that has a network of pores, such as open porosity. The sponge may be hydrophilic, and may be latex free. The sponge can be contacted to the skin by any one of dabbing, rolling, or rubbing to smooth out non-uniform pigmented areas on the skin. The sponge may be pre-wetted with water such that the sponge is damp upon application to the skin.
According to a particular feature, the application of the sponge advantageously smooths out the pigmentation of the tanning solution to help create a smooth, uniform color tone with minimized streaks, blotches or other areas of hyper- or hypo-pigmentation. Further refinement of coloring or pigmentation of the skin can be accomplished with following up application of damp sponge with a second sponge by any one of dabbing, rolling, or rubbing to smooth out non-uniform pigmented areas on the skin. The second sponge may be dry, such as having a moisture content of ambient or lesser moisture content such in the case of a sponge sealed in a package at a set relative humidity.
According to another aspect, localized areas of the skin may be pre-treated with moisturizer prior to contacting the applicator to the skin. Pre-treatment can be carried out on various areas of the body, notably the feet, elbows, knees, or hands of the person. Pre-treatment can help prevent unwanted, hyper-pigmentation of dry areas of the skin.
In one aspect, multiple applications of the moisturizer and tanning solution can applied to localized areas to promote a natural appearance similar to what is often observed from sun tanning. Localized areas may include the shoulders, shins, or chest area of the person. In one development, multiple applications of the moisturizer and tanning solution are applied to localized areas to create a shadowing effect to promote a 3-dimensional appearance to the localized body part. This shadowing or 3-dimensional effect can be used to enhance the appearance of muscularity or muscle definition, and may be useful for competitors participating in bodybuilding, figure, fitness shows, or the like. Localized areas may include, for example, jawline, cheeks, biceps, triceps, pectorals, abs, calves, hips, hamstrings, or cleavage.
Certain aspects call for disposition of tanning solution and moisturizer separately onto an applicator, such as a roller. The tanning solution and moisturizer can be packaged separately, and independent disposition of products allows modification of tanning solution to moisturizer ratio depending on the body part undergoing exposure, and/or depending on the skin condition of a particular client. The ratio of components can be changed based on dryness of the skin, with dry skin requiring higher concentrations of moisturizer relative to tanning solution, and oily skin requiring lower concentrations of moisturizer relative to tanning solution. The relative amounts of moisturizer and tanning solution can be adjusted during the tanning process to permit adequate working time (to prevent drying of the products) yet at the same time providing adequate tanning of the localized skin area.
In addition to methods for tanning skin, a tanning toolkit can be provided containing tools for carrying out tanning. Such a toolkit can be packaged together, and can include a roller, a moisturizer, a tanning solution, a tray for dispensing and holding the products, and a sponge.
In yet another aspect, tanning solution and moisturizer are not provided separately, but instead a tanning formulation is provided that contains both a tanning agent and a moisturizing species. Here, multiple tanning formulations are provided, such as in the form of a kit, having either varying levels of moisturizing species or varying species of moisturizer, or both. For example, a range of formulations may be separately packaged for disposition on an applicator, with formulations designed for dry, normal, and oily skin, for example, each formulation having a different moisturizing properties. In one embodiment, the formulations are similar, varying mainly in the quantity of moisturizing species relative to tanning solution.
In the case of provision of a range of tanning formulations, generally at least first and second formulations are provided, the first and second formulations having different concentrations of moisturizing species and/or different moisturizing species. In one development, the first tanning formulation has a higher concentration of moisturizing species than the second tanning formulation, and at least initially during the tanning process, the first tanning formulation is applied to the skin of the person.
Many different aspects and embodiments are possible. Some of those aspects and embodiments are described herein. After reading this specification, skilled artisans will appreciate that those aspects and embodiments are only illustrative and do not limit the scope of the present invention. Embodiments may be in accordance with any one or more of the embodiments as listed below.
The concepts described herein will be further described in the following Examples, which do not limit the scope of the invention described in the claims.
The knees, elbows, hands and feet of a client were pre-treated with Epionce Renewal Enriched Body Lotion moisturizer. A 4″ mohair roller is provided with matching tray, generally commercially available from paint or hardware stores. Epionce Renewal Enriched Body Lotion moisturizer is dispensed onto the nap of the roller, along its entire length, and the moisturizer is worked into the nap by rolling along the tray. Separately, Revelation High Definition Rapid Tan Solution (produced by Biddiscombe Sunless) is applied to the roller and the product worked into the roller. The roller is applied to the back of the leg of the client, covering approximately the entire length of the calf and about one third to one half the circumference of the calf. Immediately after application a moistened Body Blender (available from BeautyBlender.com or Rea.deeming, Inc.) is lightly brushed over the applied area to smooth out the products and to soften the edges of the application site, followed by a dry Body Blender sponge in select areas. Additional tanning solution is applied to the roller by rolling the roller into accumulated product in the tray and application continues along a localized area adjacent the first application site. Blending is carried out as above, using a wet then dry Body Blender sponges. The process is continued, with additional moisturizer being applied as needed, especially when approaching skin areas that are relatively dry. Extra passes of the applicator were done along the chest and shoulders for extra pigmentation along these area.
14 g of moisturizer and 61 g of tanning solution were dispensed onto the roller, approximately a 4:1 ratio of tanning solution to moisturizer. It is noted that some product was left over in the tray and absorbed into the nap. The client undergoing treatment had overall dry skin.
Application to the entire body took 35 minutes, and the result was a very uniform, appealing color and tone. As the tan faded over the next week to 10 days, the changes in color were gradual and subtle, with limited blotches or localized area of peeling.
