| Asteatosis (Disorder of the Sebaceous Glands) | Condition of dry, scaly skin due to a deficiency or absence of sebum that is caused by old age and by exposure to cold. |
| Seborrhea (Disorder of the Sebaceous Glands) | a condition in which overactivity of the sebaceous glands causes the skin to become oily |

| Subjective Symptoms | a symptom that is felt by the patient, but is not observable by an examiner |
| Objective Symptoms | symptoms that are visible, such as pimples pustules,or inflammation. |

| Epidermis-Composed of five layers | the outer layer of the skin covering the exterior body surface ..referred to as cuticle or scarf skin |
| Dermis | the layer of skin below the epidermis, also called derma, corium, cutis or TRUE SKIN |
| Stratum Corneum (Epidermis Layers) | the outermost layer of the epidermis consisting of dead cells that slough off..its the toughest layer of the epidermis |
| Stratum Lucidum (Epidermis Layers) | the layer of epidermis immediately under the stratum corneum in the skin of the palms and soles |
| Stratum Granulosum (Epidermis Layers) | the layer of epidermis just under the stratum corneum or (on the palms and soles) just under the stratum lucidum |
| Stratum Spinosum (Epidermis Layers) | The next layer up and is sometimes considered to be part of the stratum germinativum. , the spiny sublayer just below the stratum ganulosum contains cells that create an immune response to protect the body against foreign bodies that get through the first three outer sublayers of skin |
| Stratum Germinativum or Stratum Basale (Epidermis Layers) | In contact with dermis, stem cells; mitosis, replace more superficial cells. Keratinocytes and melanocytes (produce keratine and menanin) |
