Specification

FIELD OF THE INVENTION

[0001] The present invention relates to a dermal composition and method for synthesis thereof that is capable of treating hard, scaly, velvety dark skin by working on overgrown keratinocytes without changing the skin pH as well as preventing the adverse effects on the skin, thereby improving the skin conditions.

BACKGROUND OF THE INVENTION

[0002] Acanthosis Nigricans is a common skin problem, but it is considered as an orphan disease by the pharmaceutical sector. Therefore, not much work had been done on this condition. Dermatologists had very limited choice of products to treat this condition but still the results were not satisfactory as none of the products were as good to treat this problem. In most cases, multiple product therapy is given which increases the financial burden on patients and incompliance. Lack of scientific support in the previously available products also became a major factor to question the efficacy and safety of the previously available products.

[0003] Conventionally, various ointments and dermal cream are synthesized that are available for treating the darker areas of an individual. However, the application these products over the skin damages the healthy skin, lower the pH of the skin which makes its unsuitable for the sensitive skin. Due to the more deposition of keratinocytes within the darker skin of an individual, the skin of an individual becomes dark due to the moisturizer agent within the cream is fails to penetrate into the skin layers that minimizes the efficacy of the skin as well as causes dryness of the skin. Therefore, there is a need of a solution.

[0004] CN105569635A discloses about a a traditional Chinese medicine formula for treating acanthosis nigricans. The traditional Chinese medicine formula comprises Chinese medicinal herbs including root of shortlobe ligusticum, root of delavay ampelopsis, Chinese alangium root, star-flower lysimachia, oriental bittersweet root, betel pepper leaf, large-leaved uncaria root, Polygonum hydropiper, root of Paliurus ramosissimus, Lindera angustifolia, Pedicularis root, Herba alyxiae sinensis, Chinese box twig, phoenix tree root, stem of many-flower fissistigma, China creeper root, creeping fig root, bodinier beautyberry root and stem and leaf of rauwolfia. Being prepared from pure natural Chinese medicinal herbs, the traditional Chinese medicine formula for treating acanthosis nigricans is capable of treating both symptoms and root causes, exact in treatment effect, free of toxic or side effect and less prone to causing recurrence.

[0005] WO2008078154A2 discloses about an improved skin composition intended for topical application to skin for lightening hyperpigmented skin is provided. The subject composition is characterized by incorporation of at least one carbohydrate-based melanin inhibiting agent selected from bearberry extract, ascorbyl glucoside, rutin and arbutin into an ultralow molecular weight aminoglycan polymer gel. It has been found that the skin composition of the present invention possesses improved skin penetration and significantly enhances the depigmenting effect of the active agents.

[0006] Conventionally, various creams and dermal composition are known that are used to treat darker patches or skin area of an individual, however, due to the presence of steroids, the long term application of these creams causes skin atrophy which is an irreversible damage to the skin.

[0007] In order to overcome the aforementioned drawbacks, there is a need to synthesize a dermal composition that is pH stabilized due to which it does not causes any side effects to the skin. In addition, there is a need to provide a composition that is penetrated deep inside within an individual skin for increasing an efficacy as well for hydrating the individual skin.

OBJECTS OF THE INVENTION

[0008] The principal object of the present invention is to overcome the disadvantages of the prior art.

[0009] An object of the present invention is to synthesize a composition that is capable of treating dark, scaly, velvety dark skin in a safe manner without damaging an individual skin.

[0010] Another object of the present invention is to synthesize a composition that consist of moisturizers with penetration enhancer which penetrates deeply to hydrate the skin as well as for enhancing the efficacy.

[0011] Another object of the present invention is to synthesize a composition that is steroid-free which is safe for all skin types.

[0012] Yet another object of the present invention is to develop a synthesize that is effective and reliable in nature.

[0013] The foregoing and other objects, features, and advantages of the present invention will become readily apparent upon further review of the following detailed description of the preferred embodiment as illustrated in the accompanying drawings.

i) Self-evaluation of subjects:

[0031] 36 (18 males + 18 females) subjects were selected for the study. The subjects selected for this study were healthy males & females, aged between 19 and 47 years old, presenting Acanthosis Nigricans skin condition (i.e., Dark & velvety patches on skin around neck, knees and elbows).

[0032] The 36 (18 males and 18 females) subjects were selected for the study. The subject selected for this study were healthy males and females, aged between 19 to 47 years old, presenting Acanthosis Nigricans skin condition (i.e., Dark & velvety patches on skin around neck, knees and elbows).

[0033] The application was carried out by the subjects themselves at home; except the first application of test product was carried out at Mascot Spincontrol under the guidance of the CRA as showed in Table 1. The affected area was cleansed and pat dried. The required amount of the cream was applied on the area and massaged gently using fingertips. The product was applied twice a day in morning and night for the period of 7 days.

[0034] The subjects were asked to answer self-evaluation questionnaire in order to evaluate dark, velvety patches and absorption of composition regarding the efficacy of the composition over an individual. Subject’s self-evaluation of each subject was done at T+7 days after the application of composition over neck, knees and elbow regions.

[0035] The subjects filled in the questionnaire individually without any extrinsic influences (other volunteers and results of technical measurements). The filling of the questionnaires was performed under control of the CRA who checked the acquisition according to standard procedure. The questionnaires were carried out in accordance with the promoter as follows related to the product efficacy, physical characterization and product safety: i) the composition helps in reducing the appearance of dark & velvety patches on Neck, ii) The composition helps in reducing the appearance of dark & velvety patches on Knees and iii) The composition helps in reducing the appearance of dark & velvety patches on Elbows, iv) the composition spreads properly, v) the composition gets quickly absorbed in skin, vi) the composition does not cause itching, vii) the composition does not cause irritation, viii) the composition does not give burning sensation.

[0036] Referring to Table 2, a tabular representation of questionnaires were carried out in accordance with the promoter as follows related to the product efficacy, physical characterization and product safety is illustrated.

iv) Chromametry:

[0054] Tristimulus colorimeters are made of a control unit and a measurement headline associated. The measurement headline takes the measurements from a zone of 8mm in diameter and uses a diffuse lighting as well as an angle of 0° (including specular component). The headline measurement has a light with a pulsed xenon arch lamp. A double beam system measures the incident light and the reflected light by means of six photocells. The used material is a Chromameter CR-400 (Minolta).

[0055] The measurements were performed on neck, knees and elbows for skin brightening. The site of the instrumental measurements and their location at the different points of the kinetics was strictly the most reproducible. The location was determined by a cutaneous marking on the instrumental measurement sites at T0. In order to reposition this marking accurately while the measurements were taken, a mapping of the skin’s surface, for the measurement site and for each subject, was made on a transparent film.

[0056] Referring to Table 10, a tabular representation of a raw values of chromametry of dermal composition is illustrated.
