Do you know, what is Dermatillomania?
This is body-focused repetitive behaviour with continuous compulsion to pick at one’s own skin, often to the extent that damages are caused.
Episodes of skin picking are often preceded or accompanied by tension, anxiety, or stress. During these moments, there is commonly a compulsive urge to pick, squeeze, or scratch at a surface or region of the body, often at the location of a perceived skin defect.
Skin picking often occurs as a result of some other triggering cause. Some common triggers are feeling or examining irregularities on the skin and feeling anxious or other negative feelings.
The two main strategies for treating this condition are pharmacological treatment ((SSRIs; opioid antagonists; and glutamatergic agents) and psychotherapy (habit reversal training, cognitive-behavioral therapy, acceptance-enhanced behavior therapy[and acceptance and commitment therapy).
