Detailed answer

Body oils can help moisturize and improve the appearance of dry skin on the back and chest. However, sagging skin is primarily caused by a loss of collagen and elastin fibers in the skin's structure. Body oils do not have the ability to stimulate collagen production or tighten loose skin. To effectively address sagging skin, it is recommended to consider professional treatments such as radiofrequency skin tightening, ultrasound therapy, or surgery. Additionally, a well-rounded skincare routine including proper hydration, a healthy diet, regular exercise, and the use of targeted skincare products can also help improve the overall appearance and health of the skin.
