Familiarity with different types of skin fillers for rejuvenation

In this article, we will review the types of filters. Filler means filler. Fillers or gels are substances that are injected into the skin and do two main things:

  • First, they give volume and shape to the skin (for example, with age, the subcutaneous tissues decompose and the volume of the skin decreases, and in this case, the lost volume can be compensated by injecting gel).
  • Second, they can reduce the intensity and depth of the folds (for example, the lines of laughter become deeper with age and, in the form, helpless and tired. By injecting filler, the depth of these folds can be reduced).

Classification of fillers

We can divide fillers into two main categories:

Ready fillers

These types of gels are available as ready-to-inject syringes and have different types and prices. The most popular ready-made fillers are hyaluronic acids.


Fat is also a kind of filler. Fat is made from your own body. In other words, part of the tissue and fat cells of the buttocks or abdomen are removed under certain conditions and injected into the skin of the face.

You may think that because fat is made from your own body, it is of better quality and more durable, and its injection has fewer side effects, but this is not true. The injected fat actually behaves like tissue that has been grafted.

It may graft, in which case it has a good shelf life, and the fat cells may not survive in the new location, and the effect of the fat injection may soon disappear. Therefore, for small volumes, ready-made fillers seem to work better and more efficiently.

Gel injections are one of the most common and popular methods for rejuvenating the skin of the face and some other areas of the body (such as the back of the hands), because it shows its effect quickly and has few side effects. In this section, we want to introduce you to their types.

Types of fillers

Types of fillers

There are different types of ready-made fillers, and each has its own specifications that make it suitable for a particular case. We can classify ready-made fillers according to three principles:

  • Based on shelf life
  • Based on how it works
  • Based on the type of material used in the gel

Types of fillers ready based on shelf life

Based on the duration of the filler in the skin, fillers can be divided into 4 main categories:

Short effect fillers

These fillers last less than 4 to 6 months on the skin and disappear after this time. One of these gels is “Prol Silk”.

Long effect fillers

These types last for 6 to 12 months. Among the long fillers of the work, we can mention “Joviderm”, which is one of the most popular and high-quality ones.

Semi-permanent fillers

They remain on the skin for 1 to 2 years. Reedies is a semi-permanent filler.

Permanent fillers

These fillers do not disappear after injection and remain permanently in the skin.

Keep in mind that it is important to know the durability of the filler you are injecting. If you are going to inject a gel for the first time, it is better to choose a type that stays on your skin for a shorter time. First see the result of the injection and then make your final decision.

You may not be happy with the result of the injection. In this case, if you have injected a permanent filler, it will be difficult to return to the first point. Also keep in mind that as you grow older, your body shape, especially your face, changes.

The permanent type you inject today may not be suitable 10 years later! Isn’t it better to go step by step and rejuvenate with fillers that open the way for us to return?

Types of fillers based on the effect

Based on the effect, fillers are divided into two main categories:

Volumetric fillers

These types of gels replace the lost volume and only fill the empty space and have no effect on the surrounding tissues. Fillers containing hyaluronic acid such as joviderm or restylen are of this type.

Stimulus fillers

These fillers stimulate the skin to make collagen. Fillers containing calcium hydroxyapatite (such as Rhodium) are of this type.

You may think that it is better to inject stimulus fillers. What could be better than injecting a filler to make the skin of the body collagen itself and fill in the gaps and gaps? But wait!

It is true that stimulant fillers can have a longer lasting effect and, of course, seem more natural, but these gels are more difficult to work with and have more side effects. In addition, stimulant fillers can not be used to give volume to all areas of the body, for example, stimulant fillers should not be used in areas where the skin is thin, such as under the eyes.

Types of fillers based on the type of material used

Fillers containing hyaluronic acid

The most popular ready-made fillers are hyaluronic acids. Hyaluronic acid is a substance that is naturally present in the skin and gives volume and water to the skin and also plays a role in nourishing the skin. Hyaluronic acid can be easily injected into the skin, both to give the skin volume and shape, and to reduce the depth of wrinkles.

Hyaluronic acid is a transparent substance and is available as ready-to-inject syringes and there are different types that can be used for a specific purpose (for example, the type of hyaluronic acid used to volume the lips with the type of hyaluronic acid used to volume It is injected differently, it is different).

Hyaluronic acid injection has little side effects, and if the injection is not as desired or if there is a complication such as excessive protrusion or improper shape, it can be dissolved and eliminated with the injection of a substance called “hyaluronidase”.

Fillers containing calcium hydroxyapatite

Rheudis contains calcium hydroxyapatite, which is one of the stimulant fillers (ie, stimulates collagen production). This gel consists of two parts. It has a gel part that is absorbed within 3 months after injection and the main part stimulates skin cells to make collagen.

Fillers containing calcium hydroxyapatite are used to reduce the depth of lines and deeper layers. It should not be used around the eyes or on the lips.

Fillers containing polymethyl methacrylate

Fillers containing polymethyl methacrylate are permanent fillers and can only be used to improve laugh lines, cheek highlights or marionette lines.
