Relief from Itching

Posted by Nancy Ray on

Itch or pruritus has been defined as an unpleasant sensation that elicits the desire or reflex to scratch. Itch is the most common symptom in dermatology. It is also the most common skin complaint in people over the age of 65 years and it can have a major impact on an individual’s quality of life.

Itch has many similarities with pain, but the responses to itch and pain differ since pain evokes a withdrawal response and itch evokes a scratch response. We all know that the itch sensation can be reduced by the painful sensation caused by scratching. Studies have also shown that various other types of pain stimuli can also reduce itch. In some ways, itch and pain are regarded as closely related, however, itch and pain are different sensations that are processed by distinct sets of neurons.

There are at least 4 distinct classifications of itch:

  1. itch caused by skin disorders or skin damage including atopic dermatitis (eczema), psoriasis, hives (uticaria), dry skin (xerosis) and insect bites 
  1. itch caused by systemic disorders or disease such as cancer, chronic liver or kidney disease (neurogenic), 
  1. itch caused by damaged nerves (neuropathic) such as from multiple sclerosis or peripheral neuropathy (often associated with diabetes) 
  1. itch caused by psychological stress or delusions (psychogenic) 

Itching caused by dry skin or xerosis can be reduced by avoiding harsh soaps and gels and by using Viniferamine® Clean N Moist, which is designed to cleanse, moisturize, protect and nourish skin. Viniferamine® Clean N Moist is perfectly pH balanced to ensure that even the most fragile skin is gently cleansed without causing irritation. Phospholipids, organic phytonutrients, organic shea butter and other vital nutrients found in Viniferamine® Clean N Moist nourish and revitalize skin.

Nourishing, Hydrating and Protecting Skin

Daily application of Viniferamine® Renewal Moisturizer will help keep skin hydrated, nourished, and protected. Viniferamine® Renewal Moisturizer contains the most potent doses of Viniferamine® and the scientific ingredients. Viniferamine® Renewal Moisturizer, like all of the Viniferamine® skincare products, contains phytonutrients, vitamins and amino acids to nourish and strengthen skin, as well as powerful antioxidants to help decrease inflammation and skin irritation.

To help reduce dry skin it is also important to keep indoor air humidified and somewhat cooler, avoid dehydration and prolonged exposure to water when bathing or swimming, avoid high temperature bath water, avoid exposure to cold air and wind, and avoid alcohol and hot or spicy food. In addition, it is important to keep fingernails short and rub itchy skin gently to prevent skin damage resulting from scratching. This will also help prevent the “itch-scratch-itch” cycle.

 Histamine produced by dermal mast cells is an important mediator for itch in several conditions including hives, insect bites, and some drug reactions. The weal and flare response is associated with histamine-mediated itch. Evidence suggests that histamine is probably not a major mediator of atopic dermatitis or eczema. Instead, it is believed that eczema is likely to result from a decrease in barrier function that may allow allergens to irritate skin more easily. Viniferamine® Hydrocortisone Cream 1% can help reduce itching resulting from histamine release or eczema. Viniferamine® Hydrocortisone Cream 1% helps reduce inflammation, rash and swelling associated with skin irritations that result in itch.

Acute vs. Chronic Itch

Finally, it is important to distinguish between acute and chronic itch, since chronic itch is significantly more unpleasant with many similarities to pain. Chronic itch lasts more than a few weeks and is often not amenable to treatments for acute itch. Chronic itch is not as well understood and has not been as well researched as acute itch, but can be as debilitating as chronic pain and can lead to symptoms of sleeplessness and depression. The treatment of chronic itch is more complex and may involve multiple therapies.

To help prevent or stop itching, it’s good to know that Viniferamine® Renewal Moisturizer and Clean N Moist help decrease inflammation and increase skin hydration. Viniferamine® Hydrocortisone Cream 1% can also provide temporary relief from acute itching due to minor irritations.
