Question: 1 / 400

What does faradic or sinusoidal current do to your skin?

Causes skin irritation

Detoxifies the skin

Improves muscle tone and stimulates

Faradic or sinusoidal current improves muscle tone and stimulates the underlying muscles when applied to the skin. These types of electrical currents are commonly used in beauty and skincare treatments to help tone and strengthen the muscles, leading to improved skin appearance and firmness. This stimulation can help reduce the signs of aging and promote a more youthful look. Therefore, the correct answer is "C. Improves muscle tone and stimulates."

Option A, causing skin irritation, is incorrect because when administered correctly, faradic or sinusoidal currents should not cause skin irritation. Option B, detoxifying the skin, is not typically a direct function of these types of currents. Option D, whitening the skin, is not a known effect of faradic or sinusoidal current on the skin.
