Lee Jin-soo's plastic surgery essay "Elasticity and Gravity," so let's take care of the elasticity.

Newton's discovery of the law of universal gravitation dictates that all objects living on Earth are subject to gravity. We're living under a force pulled down by gravity. The skin surrounding our faces is also affected by this gravity. While under gravity, it still retains the shape surrounding the facial skeleton because it has the elasticity of the skin itself. Of course, even when it's not clearly stretched, it's still affected by the gravitational effects on the skin.

In 2008, the International Space Station (ISS) conducted a body change test on Yi So-yeon, the first Korean astronaut. We were going to take a shot of the face with a special filming device and see what happens. In space, gravity became so small that a strange change occurred four days after it was put on the ISS. Her face became slimmer and wrinkles on her forehead and skin became less wrinkled and eyebrows were raised as well. The nose became short and high. As the gravity of the skin disappears, the chin line's skin goes up and narrows down, and the skin on the forehead and nose cheeks comes forward and becomes a three-dimensional face. And if you think about it the other way around, we have a face that's wider and thinner and older than the bone itself because of gravity.

We can't go into space because our faces look older, so we have to find a way to resist gravity. As I mentioned earlier, the way to do that is to maintain or restore elasticity.
There are two important factors that determine the facial contour: One is the facial bone that forms the base skeleton, and the other is the soft tissue that covers it (skin, subcutaneous fat, fascia, muscle, etc.). An attractive contour of the face appears when the two are harmoniously well-shaped.

Among the two important elements of the face, the area associated with aging is the area of the cartilage. In particular, the skin becomes less elastic which is the core changes in the skin, is stretched beyond the force of gravity. In conclusion, restoring elasticity is a key factor in preventing aging and having an attractive face.

There are two main ways to restore skin elasticity. One is to increase the elasticity of the skin itself and the other is to pull out the slack.

The way to increase the elasticity of the skin itself is to stimulate the skin, the subcutaneous fat, the periosteum, etc. with energy to induce the regeneration process to increase the elasticity. Examples include high frequency therapy using high frequency waves, elastic laser using ultrasonic energy, and injection of components into the skin to induce regeneration. Each of them has different working parts and operating mechanisms, so you can use a variety of methods that are appropriate for saggying conditions.

The simple way to pull the slack is to use the thread lifting, and then to make an incision in front of the ear, pull the SMAS layer and then to resect the remaining area.
There are so many different ways to lift, so it is recommended to carry out comprehensive and systematic lifting through precise consultation with experts when you want to restore momentum.

The fundamental facial features can be transformed by facial bone surgery, such as facial contouring and 2 jaw surgery. Facial bone surgery doesn't seem to have much to do with elasticity, but it never does. If you reduce the skeleton by facial contouring and 2 jaw surgery, the elasticity of the soft tissue that covers the bone may have to deal with 
the reduction of the bone, but it can change the shape of the face that you want.

In conclusion, not only should the bone shape change from the planning of the bone surgery, but also the skin elasticity of the person to be operated on should be thoroughly understood and planned. If the skin lacks elasticity, consider how to improve it to achieve final good results.
