The use of infrared light in facial treatments for dry skin primarily stimulates which glands?

Sweat glands
Endocrine glands
Sebaceous glands
Lymph glands

The correct answer is: Sebaceous glands

The correct response indicates that the use of infrared light in facial treatments for dry skin primarily stimulates the sebaceous glands. Sebaceous glands are responsible for producing sebum, an oily substance that helps to moisturize and protect the skin. When infrared light is applied to the skin, it penetrates deeply and can help to enhance circulation, which in turn stimulates these glands to produce more sebum. This increased sebum production can help alleviate dryness, making the skin appear more hydrated and supple. In contrast, other glands mentioned in the options serve different functions. Sweat glands are primarily involved in thermoregulation and cooling the body through sweating, and they do not play a significant role in lubrication or moisture retention in the skin. Endocrine glands secrete hormones that regulate various bodily functions but do not directly affect skin hydration. Lymph glands are part of the immune system and are not responsible for moisturizing the skin. By understanding the unique roles of these glands, it's clear why stimulating sebaceous glands through infrared light is particularly beneficial for addressing dry skin.
