How long does hyaluronic acid last?

Hyaluronic acid is a type of hyaluronic acid that is also found in the dermis of the human body. Hyaluronic acid can help the skin lock in moisture and keep the skin plump and elastic. Now in the plastic surgery industry, hyaluronic acid has very obvious effects. How long can the effects of hyaluronic acid injection last during plastic surgery? The duration of the effect is related to the body's metabolism and the size and molecular weight of the injected hyaluronic acid molecules. Generally speaking, the effects of a hyaluronic acid injection can last about a year. We all know that hyaluronic acid can help with rhinoplasty and chin filling, but during certain periods, such as women’s menstrual period, hyaluronic acid cannot be injected into the human body.

What is Hyaluronic Acid?

Hyaluronic acid (Hyaluronan), also known as uronic acid and hyaluronic acid, is a large polysaccharide composed of two disaccharide units, D-glucuronic acid and N-acetylglucosamine. Unlike other mucopolysaccharides, it does not contain sulfur. Its hyaluronic acid molecules can carry 500 times more water and are recognized as the best moisturizing ingredient today. They are widely used in skin care products and cosmetics.

Hyaluronic acid benefits

A large number of studies have shown that the moisture content of the human skin surface layer (stratum corneum) is about 15-30%. Values ​​lower or higher than this will make people uncomfortable, with a dry or greasy feeling. If this continues for a long time, the skin will become dry or chapped, causing the skin to lose elasticity, become rough and aged. After hyaluronic acid (HA) acts on the skin for internal conditioning, it can automatically adjust in different environments and always maintain the skin's moisture at 25-30%, keeping the skin moist and refreshed, making the skin more elastic, and playing a role in anti-wrinkle, delaying the aging of the entire skin, and beautifying the skin. Hyaluronic acid is one of the components of the human dermis. It has the ability to retain moisture at a level up to 100 times its own weight. Using skin care products containing hyaluronic acid HA can improve dry and wrinkled skin and restore its original smoothness and elasticity. Therefore, hyaluronic acid is the most ideal product for improving dry and aging skin.

How long does hyaluronic acid last?

1. Related to the size of hyaluronic acid molecules

According to experts, commonly used hyaluronic acid can be divided into small molecules, total score and large molecules. Plastic surgery experts will use hyaluronic acid of different molecules according to the situation of each patient. After hyaluronic acid filling, it will be continuously absorbed by the human body. Usually, small molecule hyaluronic acid can last about half a year, medium molecule hyaluronic acid can last about one year, and large molecule hyaluronic acid can last about one and a half years.

2. It is related to the patient’s own situation

Hyaluronic acid is a substance in the basal layer of human skin. After injection, it will be absorbed and decomposed by the human body. The metabolic rate of each person's body is different. With different metabolic rates, the absorption and decomposition rates are naturally different.
