Saggy skin occurs due to aging, weight loss, or decreased collagen production, leading to skin laxity and drooping. It can affect areas such as the face, neck, arms, and abdomen, impacting one’s appearance. Advanced treatments can tighten and rejuvenate the skin, restoring a youthful and firm look. Saggy skin may also contribute to wrinkles and a loss of definition, affecting overall confidence and self-image.
