Skin tightening refers to various cosmetic procedures aimed at improving the firmness and elasticity of the skin. As people age, skin can lose its natural collagen and elastin, leading to sagging and wrinkles. Treatments can include non-invasive methods like radiofrequency therapy and ultrasound treatments, as well as surgical options like facelifts. These procedures work by stimulating collagen production or removing excess skin. Non-invasive techniques typically require little to no downtime, while surgical options may involve longer recovery periods. Overall, skin tightening aims to enhance appearance and boost confidence by creating a more youthful look.
