I also collected subjective data of my patient from thorough history. The result of data collected was as follows:
Once a person has been sensitized to an offending substance, further exposure may result in relatively rapid development of local inflammation with erythema, papule formation, induration, and weeping vesiculation. Inflammation usually begins about 12 hours after exposure; intensity peaks in 50 hours or more.
The rash may spread locally around the margins of the original site or to distant sites that did not have contact with the allergen. Potentially, the entire skin surface could become involved a condition known as erythroderma or exfoliative dermatitis.
Allergic contact dermatitis results from a true allergic i. Cross-reactivity with antigenically similar substances may occur. Initially, during the refractory period, the patient may be exposed without developing a reaction.
During the induction phase, which may last from 4 days to several weeks usually about 14 to 21 daysthe development of complete allergic sensitization occurs as the allergen comes in contact with the skin.

Skin Care Products Overview Today, market segmentation studies have become crucial for organizations looking to gain detailed information about each individual segment of the market. The purpose of market segmentation is not confined to sell products and services; but .
After the skin is fully sensitized, further contact with the allergen may result in rapid and severe dermal manifestations. When no further contact with the allergen occurs, the patient is in the period of persistence of sensitivity.
The level of sensitivity can decrease over time, but sensitization may be lifelong. Most allergens that cause allergic contact dermatitis have molecular weights of less than daltons. The allergens are haptens rather than complete antigens; they must penetrate the skin and combine with endogenous proteins to form full antigens.
Langerhans cells play a key role in then presenting the antigen to T lymphocytes, thereby activating the T cells. The sensitized T cells proliferate in the paracortical regions of the lymph nodes and produce effector and memory lymphocytes that remain in the general circulation.
On subsequent contact with the complete antigen, the effector cells release lymphokines that may result in rapid and severe, local inflammation. Many factors can affect the development of allergic contact dermatitis, including characteristics of the allergen itself, patient factors, and environmental conditions.
Allergen factors include the physiochemical nature of the allergen e. Page Share Cite Suggested Citation: Skin Lesions and Environmental Exposures: Integrating a Missing Element into Medical Education.
The National Academies Press. In addition, age and genetic predisposition can influence the development of allergic contact dermatitis. Persons who have histories of atopic dermatitis have been reported to have decreased risk of developing allergic dermatitis but increased risk of developing irritant dermatitis.
Common predisposing environmental factors for allergic contact dermatitis are pressure, friction, heat, and prolonged immersion in water such as occurs during wet work.
Relative humidity, ambient temperature, and season of the year also play roles in development of allergic contact dermatitis. Only several hundred of the thousands of chemicals used are known to cause allergic contact dermatitis.
With the exception of nickel, cobalt, and some forms of chromium, most metals do not produce sensitization. Strong inorganic alkalies and acids seldom cause allergic reactions. Aromatic compounds with polar or ionic substituents are typically sensitizing agents e.Skin care is one of the biggest categories to witness a huge increment in unit prices in , due to the free fluctuation of the Egyptian pound and customs.
By the third quarter of , the unit prices increased whereby some brands tripled in price.
The key was to further segment the sun protection products market by two important factors: Skin type and the climate where the products are used. Skin types include very light, fair, normal, dark and children (who tend to have thinner, lesser developed skin) while the climates include moderate, hot and very hot.

they have expanded significantly in the UK market through effective segmentation that matches consemer needs. To keep the skin in a healthy condition she should implement an effective skin care regime to include cleansing, toning and moisturizing twice a day.
For best results, she also should exfoliate twice a week, apply a good mask once a week and see a beautician for a facial once a month. Based on the primary survey, though certain consumers are keen to shift towards natural/ Ayurveda products, the perceived health benefits have to be quantified by the manufacturers to create demand for the segment Synthetic / Allopathic products dominate the preference for skin care products in the north and south zones.
