Skin changes range from erythema to blistering and ulceration, often on or near the hands but occurring on any exposed skin surface. This causes skin barrier disruption, epidermal cellular changes, and cytokine release . Irritant contact dermatitis is caused by direct toxicity without prior sensitisation, and allergic contact dermatitis is a delayed hypersensitivity reaction. Repeated contact with gentler substances like soap or even water can lead to irritant contact dermatitis in some situations. If exposure to the irritant or allergen continues, the … Direct damage to the skin induces barrier dysfunction, epidermal cell stimulation, and pro-inflammatory mediator release leading to a visibly variable, itchy cutaneous reaction. It presents as acute, subacute, or chronic eczema. The most common causes of irritant contact dermatitis are solvents and cutting fluids, which are used in machining. Contact dermatitis causes the skin to become itchy, blistered, dry and cracked. In almost all cases of dermatitis, a rash develops after exposure to an allergen or irritant.

Irritant dermatitis is caused by something that physically, mechanically, or chemically, which disrupts the skin barrier. Irritant contact dermatitis arises from sufficient inflammation due to the release of proinflammatory cytokines from keratinocytes, in response to chemical stimuli.

Results in localised burning, stinging, itching, blistering, redness, and swelling at the area of contact with the allergen or irritant. Endogenous and exogenous factors play a role in the skin barrier disruption and damage to keratinocytes and pro-inflammatory mediator release resulting in a clinical presentation of contact dermatitis. There are many substances related to irritant contact dermatitis (CD), causing irritant or toxic effects, e.g., chemical and physical agents, plants, phototoxic agents, airborne irritants, etc. Some rashes happen immediately, however some take time to appear (up to 1 week or more) When signs and symptoms appear, you may have: Itchy skin (often intense).
