Detailed answer

Moisturizers can help hydrate the skin and improve its elasticity, which may temporarily reduce the appearance of sagging chest skin. They create a thin barrier on the skin's surface, trapping moisture and preventing dehydration. However, moisturizers do not have the ability to firm or tighten the skin in a significant manner. For long-term improvement, sagging chest skin may require more targeted treatments such as radiofrequency therapy, laser treatments, or surgical interventions like a breast lift. It is essential to consult with a skincare professional or dermatologist for a comprehensive evaluation and personalized treatment plan.
