What technique may be used for the longest period with a client who has sluggish skin?

Pétrissage is the correct choice for a technique that may be used for the longest period on a client with sluggish skin due to its gentle, rhythmic kneading and squeezing motion. This technique promotes circulation and enhances lymphatic drainage, which is particularly beneficial for sluggish skin that often lacks vitality and proper blood flow. Pétrissage can be applied for an extended duration because it is soothing and does not overstimulate the skin.

The focus of this technique is on kneading and manipulating the muscles and soft tissues, encouraging relaxation while also addressing issues related to sluggishness. By effectively working the tissue, Pétrissage helps to revitalize and invigorate the skin, making it an ideal choice in this scenario. Other techniques may be more intense or quicker in nature, which may not be suitable for prolonged application in a situation where the skin is sluggish and requires a more nurturing approach.
