Which of the following treatments helps with sagging skin?

The treatment known to help with sagging skin is facial microcurrent. This technique utilizes low-level electrical currents that stimulate the facial muscles, promoting toning and tightening of the skin. The microcurrent acts at a cellular level, enhancing collagen and elastin production, which are crucial for maintaining skin elasticity and firmness. As a result, this treatment can produce a lifting effect, making it particularly effective for clients who are concerned about sagging or lax skin.

In contrast, microdermabrasion focuses on exfoliating the outer layer of skin, improving its texture and appearance but not directly addressing skin firmness. Facial peels aid in superficial skin resurfacing and can improve the overall tone and brightness but do not specifically target sagging. Essential oil therapy is more about promoting relaxation and soothing the skin rather than providing a tightening or lifting effect. Thus, facial microcurrent stands out as the most suitable treatment for sagging skin among the options provided.
