About

This study does not involve any particular diagnosis. The goal of this research study is to explore the effects of artificial sunlight (ultraviolet B radiation; UVB) on the skin of young adults versus geriatric adults. Sunlight exerts many effects on the body. There is evidence that in response to ultraviolet B radiation (UVB), which are the burning rays of sunlight, young adult skin responds differently than geriatric skin. In fact, researchers feel that this difference in how the skin reacts to UVB is why skin cancers are found in older skin. Researchers believe that a major difference between young adult and geriatric skin is that young skin has a lot of a protein called insulin-like growth factor-1 (IGF-1), whereas geriatric skin has very little. The current study will test how young adult versus geriatric skin responds to UVB, and if geriatric skin treated with an injection of small amount of IGF-1 drug will then act like young skin.

---

24 participants in 2 patient groups, including a placebo group

Young Adult

Placebo Comparator group

Description:

One small area of skin will undergo treatment with a small amount of UVB.

Treatment:

Other: No Insulin-Lie Growth Factor 1

Geriatric Adult

Active Comparator group

Description:

Four small areas will undergo injection of a small amount of IGF-1 drug and two will undergo injections with saline. Then the injected areas will be treated with a small amount of UVB.
