The foot, an area naturally subject to calluses
Dry skin on the feet is quite a common occurence. Indeed, the foot is naturally poor in sebaceous glands, which nourish the skin and avoid drying out. What’s more, with age, feet produce less and less sebum and become more and more dry.
Contrary to what we may believe, sweat doesn’t avoid dryness. The most sensitive part is of course the heel, on which we can find heel calluses, which, if not treated, can cause cracks then crevices – which can be very painful.
Hyperkeratosis – cutaneous dryness – is due to excess pressure on the heel: skin tries to protect itself and creates calluses. If there is too much callosed skin, there is a risk of cracking. As long as cracks remain on the surface, on the epidermis, it’s superficial. But as soon as they reach the derma, it becomes very painful.
