Some people experience ahand rashafter washing their hands, and there are several reasons whyhandwashingmight cause this.
Simply overwashing the hands can compromise thebarrier function of the skin, causing irritation.
Scrubbing and water temperature can also contribute as can any allergy you might have to the cleansers you use.

The skin on the palms is much thicker and more resistant to irritants and allergic rashes.
This article explains some of the more common causes of hand rashes resulting from handwashing.
Its primary role is to protect the body from infection and environmental irritants.

Part of this protection is afforded by natural oils on the skin.
Atop the outermost layer of skin (epidermis) is a layer called thestratum corneummade of dead skin cells.
The stratum corneum is important because it blocks bacteria and other microorganisms from entering underlying tissues.
It also serves as the scaffolding onto which sebum clings.
Compromising these functions can cause skin problems including rash.
Fragrances found in soaps, cleansers, and moisturizers are also common triggers.
Changing skincare products may help you avoid future outbreaks.
In their place, use a mild, fragrance-free soap without dyes.
Sebum also coats the skin so that moisture is repelled.
The downside to this is that up to 30% of healthcare workers develop hand rashes due to overwashing.
Rather than overwashing, give your skin a break by occasionally using an alcohol-based hand cleanser.
Hot Water Temperature
Hot water temperature also plays a role by overheating the skin.
It is always best to wash your hands with lukewarm or cool water.
Scrubbing
Scrubbing the skin vigorously eliminates the stratum corneum.
It also exposes underlying pores, called hair follicles, to invasion by bacteria and other microorganisms.
The constriction of blood vessels also robs the skin of oxygen and nutrients that it needs to thrive.
This can worsen existing skin conditions likeatopic dermatitis (eczema).
An unscented moisturizing cream can help with skin dryness and prevent cracking and itching.
It’s best to use creams and ointments instead of lotions, as they are richer.
Plain white creams are also safer choices.
Crisco is an acceptable alternative that can be cost effective.
In these situations, there are typically other symptoms besides a rash.
But sometimes you may need to see a healthcare provider for a hand rash.
To prevent a hand rash, avoid washing with hot water or harsh soaps.
Refrain from soaking or scrubbing the hands too vigorously, and apply a thick moisturizer after washing.
Lighter skin may redden.
Darker skin tones may appear gray, dark brown, or purple.
You may be getting hand rashes for a variety of reasons.
You may be allergic to the soap you use on a daily basis.
And some people have a condition called eczema, which causes a rash as well.
Mild skin allergic reactions usually go away after a few days or weeks.
But if your rash sticks around for a long time, call a healthcare provider.
