Comedones are small, flesh-colored, white, or dark bumps that give skin a rough texture. The bumps are caused by acne. They are found at the opening of skin pores. A solid core can often be seen in the middle of the small bump. Open comedones are blackheads and closed comedones are whiteheads.

Lichenification
The term lichenification is classed as a secondary skin lesion wherein the characteristic features of skin thickening, hyperpigmentation, and exaggerated skin lines are noted.
Fissure

In addition to being uncomfortable, fissures can be a precursor to skin ulcers. For this reason, treating skin fissures before they worsen is important.
Excoriation
Excoriation disorder is characterized by recurrent picking of one’s skin resulting in skin lesions. Patients with excoriation disorder repeatedly pick at or scratch their skin; the picking is not triggered by cosmetic or health concerns (eg, to remove a lesion that they perceive as unattractive or possibly cancerous).
