Things You Should Know About PLLA Injection

The world of cosmetics has seen a lot of development and improvement in the past couple of years. From the usual powder and makeup that people wear – to surgeries and implants for a lot of parts of the face and the body.

Among the many different types of aesthetic materials and innovations, PLLA injection has been the most famous and the most used.

In this article, we’ll be discussing about the details about PLLA Injection. Without further ado, let’s head straight on what you should be aware of when it comes to dermal fillers!

Why Use PLLA Polymer Material?

PLLA, short for Poly-L-Lactic Acid, is a type of injection that people use for maximal correction and improvement. More common than not, it’s used in correcting facial defects, and it offers a permanent and a long-term solution for patients that have deficits with their facial features.

While there are a lot of other medical grade polymers that are synthetic, a lot of people choose PLA injection because of the following:


One of the main benefits that you can get if you use PLLA is that it’s renewable. In addition to that, it’s also made from raw materials.

Therefore, it’s clear that these are materials that are safe-to-use and that are environmentally friendly.

Excellent Quality Performance

Another advantage that you can get from using it would be with collagen synthesis, which offers deep-tissue regeneration. Because of how they’re structured, they promote the regeneration of cells at a deeper and more serious part.

Its outstanding effects will gradually become more apparent and will increase for over a long period of time, making it a permanent solution to a cosmetic problem that you are experiencing.

PLLA helps in the stimulation of collagen fiber proliferation, therefore, it further strengthens the integrity of the skin.

This is among the many reasons why it’s mostly used for revitalizing the skin in different areas such as the temples, cheeks, the chin, and so on. It’s been deemed as one of the best and the most effective skin preservation materials and ingredients.

Little-to-No Immunogenic Response

You can expect that there’ll be little-to-no negative or immunogenic reactions. But, it’s worth noting that the raw ingredients and/or materials used are safe and are compatible with the wide majority of skin types.

Those are just three (3) of the reasons why you should consider PLLA injections instead of other options. But, there are others; in fact, there are a lot more you can choose from! But with these benefits, you’ll surely not mind the other choices you have.

Microspheres Diameter

When it comes to the content of dermal fillers, they’re packed and filled with content that contribute to the powerful effects of the dermal fillers.

Following that, the microspheres diameter of the content of dermal fillers are distributed evenly. What this means is that it contains solutions that point directly towards its effects – to get rid of wrinkles, lines, and the like.

Injection Position

PLLA is known for its revitalizing nature. That being said, it can straightly be injected in a lot of different positions and places.

However, the most common places would be in the following parts:

  • Lower part of the face
  • Mid-cheek to lower cheek region
  • Temples

To be able to achieve the best results, the needle must be inserted at an angle of 30 to 45 degrees. It needs to be following the flow or the direction of the wrinkle or the inconsistency within the region you’re looking to fix.


In choosing the specific type of PLLA injection or dermal filler you need to utilize, you can find it in many different specifications.

These differences are used to specify the particular use they have for it. PLLA that have higher molecular weights tend to have better physical properties. For instance, those that are heavier can produce and provide more effects than those that are lighter.

Since then, and until today, PLLA that has higher and heavier molecular weight are lactide polymerization through its outer layer.

On the other hand, lower molecular-weighted polymers have increased rates of degradation because of the low intake of water. Furthermore, they have higher concentration of end groups of carboxyl.  

Side Effects

Injectable PLLA is one of the best, but it doesn’t mean it yields no side effects. Akin to how other products and materials are, the usage of PLLA isn’t actually perfect.

As a matter of fact, there could be side effects that might not be comfortable or convenient for you. 

Swelling and Inflammation

Since it‘s applied through deep injection, it can cause inflammatory or swelling reactions that are connected to injections.

These side effects could include:

  • Redness of the area where it was injected
  • Dull and sharp pain within the region of injection  
  • Swelling
  • Itchiness on the area and the surrounding area
  • Temporary lumps

Can Bruising Be a Side Effect?

There have been some cases where people have reported to have seen swelling on the site of injection. It was a mere 21% of the total data and was a pretty high amount.

While these may seem alarming, you can actually take care of these easily. With proper hygiene and care especially on the injection site, you’ll be able to get rid of these.

In addition to those common side effects, there are uncommon side effects that some patients may experience, too. These include:

  • Mild to serious infections
  • Cysts and blisters
  • Scars and marks
  • Numbness

If you’re experiencing any of these on a constant basis, the next best thing to do is to contact the cosmetologist you worked with the PLLA injection you had.
