Michigan Esthetician State Board Exam Practice 2026 – Complete Prep Guide

High-density lipoproteins (HDLs) are a type of cholesterol found in the body, often referred to as "good" cholesterol. They play a crucial role in transporting cholesterol from other parts of the body back to the liver, where it can be processed and eliminated. This process helps reduce the risk of heart disease and stroke, as HDLs help prevent the accumulation of cholesterol in the arteries.

Understanding HDLs is vital in the study of esthetics, particularly in relation to skin health and appearance, as factors like cholesterol levels can influence skin conditions and overall radiance. The other options presented do not accurately define HDLs—high-density lipids, high-density liposome compounds, and high-density lactones do not exist in the context of cholesterol transport and health. Therefore, identifying HDLs as high-density lipoproteins is essential for a clear grasp of the subject within the realm of health and esthetics.
