Which of the following effects is associated with galvanic current?

1. Decreases skin temperature

2. Attracts oils to the skin

3. Contracts blood vessels

4. Increases muscle flexibility

The correct answer is: Contracts blood vessels

The effect associated with galvanic current is that it contracts blood vessels. Galvanic current, which is a direct current used in various esthetic treatments, primarily affects the skin and underlying tissues through its ionic effects. When applied, this current can stimulate blood circulation initially; however, it can also lead to vasoconstriction—a process where blood vessels narrow, reducing blood flow to certain areas. This is particularly useful in treatments aimed at reducing redness or swelling. The other options do not accurately reflect the primary effects of galvanic current. While galvanic current can influence skin temperature and muscle flexibility indirectly through increased blood flow or relaxation techniques, those are not its primary characteristics. Additionally, the attraction of oils to the skin is not a function of galvanic current, as galvanic treatments are more focused on the introduction of products and hydration rather than oil attraction. Thus, the correct association with the effects of galvanic current is the contraction of blood vessels.
