Blisters can be described as a form of swelling on the skin. The raised area on the skin surface is caused by the accumulation of certain clear fluid at that spot. These are formed in the upper layers of the skin when the skin is prone to an adverse environment.

Although these are most prominent on the hands and the feet, blisters can develop on any part of the skin. Generally, blisters are filled with serum, but if the blisters are infected, they might be filled with pus or blood. They may or may not be painful.

Blisters can be broadly classified into two types based on the cause and the time they take to heal. The two categories are blisters caused due to injuries and blisters arising out of skin infections.

Blisters which are a result of injuries or irritations to the human skin are more frequent. It is commonly noticed that most of these blisters heal within a fortnight. A week or two is more than enough for a blister to be healed. They heal by natural process and do not require any medical attention.

On the other hand, blisters caused as a result of skin infections can be severe. They are often painful and require immediate medical attention from a doctor. Moreover, these blisters take nearly or over a month to be healed.

Blisters are undeniably uncomfortable. It makes you feel itchy and tempts you to pop or prick it. But if you do so, you may risk its spread to other nearby skin surfaces. Then it goes on like a cycle. The more you prick it, the more it will spread and the more time it shall consume to be healed.

In order to avoid itchiness, a bandage can be put to use. The blister has to be covered with a sterile dressing and left alone. Such a covering prompts a fast natural recovery. As a result, the fluid gets reabsorbed, your skin will slowly get even. If the proper procedure is followed, your skin may heal within a week.

Why Does It Take So Long For A Blister To Heal?

Skin friction, sunburn and medical conditions like chickenpox are the prominent factors behind the development of blisters. Similarly, the use of ill-fitted shoes can lead to blisters on the feet. The blister is nothing but your body’s reaction to these adverse conditions. As a result, serum gets filled in the affected spot and it appears swollen. The fluid so accumulated cushions the inner layers of the skin. It may surprise you but blisters are quite helpful in protecting the inner layers of your skin from further damage.

The cushioning of the dermal skin by the fluids induces it to recover and heal quickly.

It should be must kept in mind that under no circumstances, the blister should be bursted. Apart from causing further damage and reducing the healing process of the skin, bursting it may lead to skin infections. These skin infections are painful and a doctor needs to be conducted.

But if somehow the blister does gets bursted, you need to be cautious. You should let the fluid be removed while care enough that the dead skin is not peeled off the skin. Peeling off the skin may increase the area affected. Also, cover the blister spot with a sterile and dry dressing. This would help it in healing quickly. Yet, many people burst the blisters without taking any precautions which delays the healing period.

Wearing ill-fitting shoes is an another reason behind slow healing of skin. shoes with proper fitting should be preferred over loose or tight fitting shoes. Also, instead of wearing bad quality shocks, you can go for nylon or moisture wicking shocks.

Thus, it may be concluded that blisters are very sensitive to injuries and infections. The utmost care and attention should be paid to help the skin recover swiftly. The bursting of blisters and the urgency in dealing with them may further complicate the process.
