Skin Conditions: Psoriasis and Eczema and Their Effects on Nails
Psoriasis and eczema are two common skin conditions that can both have an impact on the nails. Psoriasis, characterized by dry, red patches of skin with silvery scales, is an autoimmune disease. It can not only affect the skin but also damage the nail bed and disrupt nail growth. As a result, various forms of nail ridges may appear.
Eczema, on the other hand, shares some similarities with psoriasis in terms of symptoms. It can also cause changes in skin coloration. In addition to nail ridges, eczema can discolor the nails, making existing nail ridges more noticeable.
Causes of Nail Ridges: Injuries
In addition to aging and illness, nail ridges can also be caused by injuries. Even if there are no visible signs of damage at the time, injuries can disrupt the proper growth of nails. It’s important to note that the nail doesn’t just end at the cuticle; it continues into the finger for a short distance. Any scratches, blunt traumas, or accidents that affect this hidden part of the nail can result in scrapes and ridges. As the nail grows and the previously concealed damage becomes visible, it may appear as though a new ridge has formed. Since nails take time to grow, it’s possible to forget about the injury by the time the ridge becomes noticeable.
