Thickening and hardening of the skin
Frequent scratching and itching of the skin can lead to crusting and scaling of the rashes, making the skin thick and hard. Skin becomes dry, thick, and hard due to low skin moisture, dryness, and continuous scratching. This thickening of the skin and exaggeration of normal skin markings can be seen on atopic dermatitis. This damage cannot be repaired that easily.
