A fissure is a state where the skin is cracked, creating a gap, which can cause pain and bleeding on the hands, feet, or folded areas.
Cracks: Please check these three things first
- Skin cracks occur when dry or thickened skin splits; they commonly appear in areas that move repeatedly, such as the fingers, heels, and corners of the mouth.
- It is easier to distinguish between simple dryness and inflammatory skin diseases by observing the depth, bleeding, and pain, as well as exposure to water, cleansers, and friction.
- Do not wait and rely solely on self-moisturizing if you experience redness, heat, pus, or rapid spreading, or if there are deep wounds on the feet of a patient with diabetes.
What are skin cracks?
This is a condition where dry or thickened skin splits deeply like a line. Cracks are gaps formed by the skin splitting, which can cause pain and bleeding on the hands, feet, and in skin folds.
How is it different from similar conditions?
They are deeper than fine dryness lines on the surface and may be accompanied by pain or bleeding.
Why is this important in skin care?
In cases of hand eczema, pompholyx (dyshidrotic eczema), psoriasis, and severe dryness, these are significant changes that can interfere with function.
What should be checked based on my symptoms?
If redness, pus, and heat increase within the crack, check for a secondary infection.
Identify the location of the cracks and any repeated irritants
Note any repeated irritants that occurred before the cracking, such as hand washing, dishwashing, disinfectants, gloves, long walks, or friction from shoes. It is also helpful to consider whether the skin was initially dry, if it cracked after scratching due to itching, if it recurs in the same spot, and if there are seasonal changes.
When should I seek medical evaluation instead of just moisturizing?
For shallow, dry cracks, management focused on reducing irritation and providing moisturizing and protection can be helpful. If pain and bleeding persist, or if the surrounding area becomes red and hot, it is necessary to identify the cause, such as eczema, psoriasis, or infection, and determine the required topical treatment and wound care.
Frequently Asked Questions
Frequently Asked Questions about skin cracks
Is it enough to just apply moisturizer to cracked skin?
While it may help with shallow dry cracks, treatment for the underlying cause is necessary if there are changes suggesting deep pain, bleeding, oozing, or infection. Irritating substances and currently used topical agents should also be reviewed.
Can I trim away the cracked dead skin?
Tearing or cutting the skin without confirming the depth and boundaries can increase the risk of bleeding and infection. Protect the area gently, and if the condition recurs, seek medical evaluation to identify the cause.
