Maceration
Maceration is the softening and breakdown of skin that occurs when it stays wet for a prolonged period. Overhydrated skin becomes pale, wrinkled, and more fragile.
It happens where moisture lingers without evaporating, such as inside footwear, within skin folds, or under coverings. The stratum corneum absorbs water and loses some of its protective strength, leaving skin vulnerable to irritation and cracking. Heavy sweating that keeps areas damp can contribute, especially on the feet or in folds. Allowing skin to dry and breathe generally reverses mild maceration. The softened surface can also be more prone to friction damage and, if broken, to further irritation. Because trapped sweat is a common driver, it links closely to conditions of enclosed, moist skin. The change is much like what happens to fingertips after a long soak in water. The outer barrier layer takes up moisture and loses its firmness. Once the skin dries out, that layer usually firms up and recovers.

In practice
Pale, wrinkled skin on the soles after hours in damp socks is a familiar example of maceration from trapped sweat. The look is much like fingertips left too long in water, and it usually firms up once the skin is dried and allowed to air out. Softened, tender skin between the toes, where moisture is easily trapped, is another common site.
Frequently asked questions
Is macerated skin permanently damaged?
Usually not. Mild maceration typically recovers once the skin is allowed to dry. The barrier layer firms up again as it loses the excess moisture.
What conditions make maceration more likely?
Prolonged moisture from trapped sweat is a common contributor. Enclosed spots like inside footwear or within skin folds are typical sites.
