To properly analyze a client's skin, one should look, touch, and ask questions. When looking, use a magnifying light to examine the skin for characteristics, conditions, and signs of aging. Touching allows you to feel the skin's texture, tone, elasticity, muscle tone, and secretions. Asking questions determines the client's skin care routine, product use, and any skin problems or concerns. A thorough skin analysis is vital for providing an effective treatment without risk of incorrect product or pressure application.
