chitosan, a chitosan derivative or a physiologically acceptable salt thereof, and a short-medium chain dicarboxylic acid, or dicarboxylic ester, or dicarboxylic amide, or a physiologically acceptable salt thereof, for the preparation of a medicament, or a medical device, or a sanitary product, or a cosmetic, forming a film after application onto the skin of the face and of other affected areas, useful for protecting skin in rosacea, a chronic inflammatory condition of the skin, and other skin conditions characterized by teleangectasia, like couperose and leg teleangectasia. BACKGROUND OF THE INVENTION Rosacea is a common but often misunderstood condition that is estimated to affect over 13 million people worldwide ( Plewig & Jansen in: Fitzpatrick's Dermatology in General Medicine. Freedberg et al. Eds., 6th ed., McGRAW-HILL pub., NY 2003, p. 688 ). It affects white-skinned people of Celtic or northern European descent, and has been named the 'curse of the Celts'. It is rarer in dark-skinned people, like American and African blacks. It begins as erythema (flushing and redness, also called \"couperose\") on the central face and across the cheeks, nose, or forehead but can also less commonly affect the neck and chest. As rosacea progresses, other symptoms can develop such as semi-permanent erythema, teleangiectasia (dilation of superficial blood vessels on the face), red domed papules (small bumps) and pustules, red gritty eyes, burning and stinging sensations, and in some advanced cases, a red lobulated nose (rhinophyma). The disorder can be confused with, and co-exist with acne vulgaris and/or seborrhoeic dermatitis. Rosacea affects both sexes, but is almost three times more common in women, is common in the third and fourth decade and peaks between the ages of 40 and 50 years. The presence of rash on the scalp or ears suggests a different or co-existing diagnosis, as rosacea is primarily a facial diagnosis. The pathogenesis of rosacea in unknown, and various factors have been suspected to contribute to this condition. Among the various factors, the following have been claimed to play a role: degenerative changes of the perivascular/ vascular collagen, that lead to small vessel dilatation resulting in flushing, teleangiectasia, erithema; perivascular leakage of potentially inflammatory substances; abnormal tissue response to cytokines and other mediators; use of topical drugs (corticosteroids). Exposure to temperature extremes can cause the face to become flushed as well as strenuous exercise, heat from sunlight, severe sunburn, cold wind, moving from cold to hot environment. There are also some foods and drinks that can trigger flushing, these include alcohol, caffeine (hot tea and coffee), and spicy food. Microorganism also have been claimed to contribute to the development or complicate rosacea, like Demodex folliculorum, Helicobacter pylori or Propionibacterium acnes. Treatment of rosacea is inconclusive. Systemic or topical treatments include antibiotics, metronidazole and antifungals; retinoids, some beta blockers, spironolactone. No causal treatment has ever been proposed, and lifelong symptomatic treatment is often necessary, as just few cases may go into a permanent remission of the symptoms. Long term treatment of rosacea is limited by the intrinsic toxicity of drugs. Leg teleangectasia consists in very thin varicose capillaries, with calibre within 0,1 and 1 mm, that are classified as follows:\n 1) Teleangectasia due to venous insufficiency, accompanied by other clinical signs of venous insufficiency. They are localized at the foot back, retromalleolar region, legs, and at the medial thigh surface. 2) Teleangectasia due to hormonal abnormalities, localized at the medial and anterolateral thigh surface. They spontaneously occur during menarche, menopause, pregnancy or under contraceptive treatment. 3) Very thin teleangectasia due to constitutional weakness of the capillary system, mainly at the distal portion of the legs. This is triggered by UV radiation, and by hot and cold temperature. 4) Matting type teleangectasia 5) Reticular varicous veins: in most cases they represent the nourishing veins for the districts that are interested by telengectasia. No satisfactory treatment exists for leg teleangectasia and the only possible treatment is aesthetic surgery. Thus, there is an unsatisfied need of safe and active medical tools to protect a skin that is unusually vulnerable to chemical and physical insults. Chitosan and its derivatives are amino-polysaccharides, derived from the chitin extracted from the exoskeleton of the crustaceans, known in the art for their use in different preparations.

DESCRIPTION OF THE INVENTION It has now surprisingly been found that preparations containing chitosan or its derivatives, and at least a short-medium chain ( from 6 to 12 carbon atoms ) aliphatic dicarboxylic acid, or dicarboxylic ester, or dicarboxylic amide, may form an elastic film onto the skin, after application and drying, suitable to protect the skin from chemical or physical insults. The two components of the film, saccharidic and lipidic, act in a synergistic way and have a protective activity superior to that of the two components alone. The film forming compositions according to the present invention may easily be sprayed onto the skin surface, by allowing quick drying and easy formation of an elastic film, that avoids bothersome sensation of oily skin. The film forming compositions according to the present invention may also be applied on the skin by gently massage. The film formed after drying protects the skin from the insult of both hot and cold temperature, decreases the inflammation due to ultraviolet radiation and prevents the growth of microorganisms by coating them and inhibiting their vital functions. The object of the present invention is thus represented by a pharmaceutical and/or cosmetic composition containing:\n (A) at least a chitosan, chitosan derivative and/or a physiologically acceptable salt thereof, and; (B) at least a C 6 -C 12 -dicarboxylic acid, ester, amide and/or a physiologically acceptable salt thereof. Said composition is useful to form a film after application onto the skin and drying, that protects the skin of the face and the other areas affected byrosacea as well as by other skin conditions characterized by teleangectasia. Among chitosan derivatives, water soluble chitosans are preferred; hydroxyalkyl chitosans, such as hydroxypropyl chitosan, being the most preferred water soluble chitosans derivatives. Among the C 6 -C 12 -dicarboxylic acids, C 8 -C 10 -dicarboxylic acids are particularly preferred, C 9 -dicarboxylic acids being the most preferred; according to additional preferred ambodiments, such dicarboxylic acids are linear and/or alkyl acids. The C 6 -C 12 -dicarboxylic acid, ester or amide which is used for the purposes of the present invention is thus preferably represented by the following formula: \n \n ROOC-(CH 2 ) n -COOR \n \nwherein:\n \"n\" is comprised between 4 and 10, preferably between 6 and 8 and, more preferably, it is 7; R is H, a C 1 -C 4 -alkyl group or a -N(R')(R\") group, \nwherein: R' is H or a C 1 -C 4 -alkyl group, and R\" is H, a C 1 -C 4 -alkyl group or a C 1 -C 4 -carboxy group. According to preferred embodiments, said C 1 -C 4 -alkyl groups are methyl or ethyl whereas said C 1 -C 4 -carboxy group is carboxy methyl. Amond dicarboxylic acids, azelaic acid is preferred, and may be in form of a salt, preferably a sodium or potassium salt. Among dicarboxylic acid esters, azelaic acid esters are preferred. Among dicarboxylic acid amides, azelaic acid amides, such as azeloyl diglycine, are preferred, and may be in form of a salt, preferably a sodium or potassium salt, such as potassium azeloyl diglycinate. The composition according to the present invention may be applied by a gently massage on the skin, or may be sprayed by allowing the formation of an elastic film after drying. The composition according to the present invention allows a long lasting intimate contact and continuous protection of the skin for many hours after the application. Compositions according to the present invention are in the form are in the form of liquid, semiliquid or semisolid preparations, including solutions, suspensions, lotions, emulsions, colloids, creams, gels, with a content in component A from 0.1 to 10 wt.% (percentages by weight are given with respect to the whole preparation), preferably from 0.2 to 5 wt.%, more preferably from 0.25 to 2.0 wt.% and with a content in component B from 0.1 to 30 wt.% (percentages by weight are given with respect to the whole preparation), preferably from 0.25 to 25 wt.%, more preferably from 0.5 to 20 wt.%. Compositions according to the present invention are superior to the conventional formulations, in that they leave an uniform and invisible film. Moreover, compositions according to the present invention do not dirty, do not dry like gels and lotions do, and do not give bothersome sensation when applied, like other rigid film preparations do. Pharmaceutical compositions are prepared according to conventional technique, using compatible excipients, adjuvants and/or pharmaceutically or cosmetically acceptable carriers, and may contain, in combination, other active principles with complementary or, in any case, useful activity. Examples of these compositions prepared according to the present invention include: solutions, emulsions, suspensions, colloids, creams, gels, for application to affected skin. The compositions according to the present invention may contain one or more additional ingredients selected from solvents, sunscreens, skin-conditioning agents, emollients, moisturizers, emulsifying agents, viscosity-increasing agents, UV-A filters, plant extracts, antioxidants.
