Immune system
A complex network of specialized cells that defend the body against infections from bacteria, viruses, fungi and other harmful agents. At times, the immune system may not function properly making the body vulnerable to certain infections. Some medical conditions are due to an overactive or poorly regulated immune system , leading to “autoimmune” diseases, such as arthritis and lupus.

Infrared laser
This is a type of laser that is used for skin-rejuvenation, including the Smoothbeam, CoolTouch, and Aramis lasers. These stimulate collagen production and help to improve wrinkled and acne-scarred skin. An infrared laser may also be used to treat acne by temporarily shrinking the sebaceous glands.

Intense pulsed light (IPL)
This is a form of light therapy used to treat a variety of skin conditions. It is not a laser. It emits powerful pulses of broad-spectrum light that can stimulate collagen production, resulting in smoother, less-wrinkled, younger-looking skin. IPL can also be used to remove unwanted hair, reduce the appearance of brown spots, and reduce redness and facial red blood vessels often associated with rosacea.

Isolaz
(see PPX System)

Isotretinoin
Isotretinoin is an oral retinoid, derivative of vitamin A,  used for the treatment of moderate to severe acne. Brand names include Accutane, and Sotret. Isotretinoin opens up sebaceous glands (“pores”), reduces oil production, and may have has some anti-inflammatory benefits as well. It is associated with many side effects, including dry skin and chapped lips, and can cause severe birth defects in a child if the mother takes isotretinoin while pregnant. Because of these side effects, the use of isotretinoin is often reserved for those patients whose acne has not responded to other treatment options, such as topical retinoids, or who have severe cystic acne that can lead to permanent scars.

The iPledge program has been developed to prevent pregnancies by people taking isotretinoin.
