My chin is swollen and hard several months after I had it done

In this society where appearance is everything, more and more people are pursuing perfect appearance. Therefore, the market for plastic surgery is growing day by day, and more and more beautiful women and even handsome men go to plastic surgery hospitals to seek help to make up for the shortcomings of their innate appearance. However, I would like to advise everyone here to go to a regular hospital for fine-tuning. So what is the reason for the chin to be swollen and hard several months after the chin was injected? Let’s take a look together below.

Hyaluronic acid, whose scientific name is hyaluronic acid or uronic acid, is a straight-chain high-molecular polysaccharide composed of disaccharide units. It is a substance that exists naturally in tissues. In nature, it is widely present in the connective tissue, mucous tissue, lens of the eye and capsule of some bacteria of vertebrates.

Hyaluronic acid is a substance that the human body possesses. It can help moisturize the skin and lubricate the joints, and plays an important role as a matrix in the dermis of the skin.

Baby skin has the highest content of hyaluronic acid, so the skin is hydrated and plump. However, hyaluronic acid will disappear with age. Compared with the skin of 20-30 years old, the hyaluronic acid content in the human body is 75% at the age of 30-40, and only 60% of the original content at the age of 40. During the aging process of the skin, the hyaluronic acid content will decrease, the skin's moisturizing ability will decrease, the elasticity will decrease, and fine lines will appear.

Hyaluronic acid can be supplemented artificially to replenish the lost hyaluronic acid, thereby naturally filling wrinkles or achieving local filling to plump up the body curves. Pure hyaluronic acid is non-immunogenic and will be gradually absorbed by the human body.

There are three main sources of hyaluronic acid: animal tissue extraction, bacterial fermentation, and artificial synthesis.

The hyaluronic acid used in our modern medical aesthetics is mostly artificially synthesized and is no longer extracted from animal connective tissue, thus eliminating problems such as allergies and infections.

Theoretically, it can eventually be metabolized by the body. Hyaluronic acid is widely used in the beauty industry, mainly for filling. Different hyaluronic acid materials are used to fill different parts.
