Polylactic acid

In modern cosmetology, fillers with
hyaluronic acid and botox. Believed to be the most
popular and popular fillers. But this amount
substances used in fillers, is not limited. In the last
polylactic acid based fillers are gaining popularity
which can make serious competition to the rest
drug.

What is polylactic acid?

Lactic acid is a substance that is found in our
body and produced naturally after decay
glucose. Synthesized polylactic acid
(poly-L-lactic acid) belongs to the family of alpha-hydroxy acids
(fruit acids) whose valuable properties
widely used in cosmetology. She’s a few decades.
successfully used in medicine and in cosmetology.

Polylactic acid is unique, biodegradable,
hydrophobic drug used for contouring.
It is produced in the form of PLA crystals. Polylactic acid,
created by synthetic means, perfectly safe. She doesn’t call
allergic reactions and does not provoke tissue rejection, does not have
properties accumulate in tissues and it is very easy to remove
decomposing into carbon dioxide and water.

How does polylactic acid in fillers

When injected into the skin, polylactic acid crystals act on
fibroblasts, causing their activation. Fibroblasts in turn
produce the production of collagen fibers. After several
weeks water from the drug is absorbed, and its place is taken
renewed tissues that are overgrown with polylactic microparticles
acid.

Then polylactic acid is decomposed into water and carbon dioxide,
leaving behind a new collagen frame. Effect of the procedure
lasts two years. Polylactic acid in the skin starts the chain
reaction in the form of the “domino principle”. Acid activates fibroblasts
(connective tissue cells), fibroblasts actively produce
collagen and elastin fibers, and in the extracellular matrix is ​​actively
heteropolysaccharides (hyaluronic acid) are released.


Thus, the metabolic processes are launched in the dermis, and
there is its rejuvenation. Polymer-based filler action
acids twice the effect of hyaluronic fillers.
Polylactic acid in fillers acts deeper and
more active. But unlike hyaluronic acid, it needs
in staging techniques (injection courses are conducted by sessions,
and not done at a time).

What skin defects can be eliminated using polylactic
acids

Polylactic acid is most often used to replenish
lost volumes, but not only for this. Application spectrum
fillers based on it is very wide. With her help:

  • fill the nasolacrimal grooves;
  • eliminate dark circles and bruises under the eyes;
  • fill the hollows under the eyes;
  • correct the area of ​​the cheekbones, nasolabial folds and
    chin;
  • eliminate sagging of the tissues on the cheeks;
  • create a clear skin texture;
  • adjust the oval face.

Polylactic acid is a versatile drug, actively
coping with age defects of the skin as in the upper part of the face
(when filling the nasolacrimal sulcus), and in the lower (with
modeling oval face).

Are there any contraindications to the use of polylactic
acids?

Polylactic acid has a number of serious contraindications. Not
It is recommended to use fillers based on it in the following cases:


  • autoimmune and oncological diseases;
  • infectious and chronic diseases in the stage
    aggravations;
  • taking anticoagulants and aspirin;
  • pregnancy and lactation;
  • the presence of keloid scars.

Side effects and complications

Side effects manifest themselves in a classic way:

  • swelling;
  • hematomas in places of injections;
  • bruises.

All symptoms disappear completely within a few days.

Complications are as follows:

  • granulomas (nodular seals).
  • allergic reactions;
  • gel aggregation;
  • Tyndall effect (contouring the gel under the skin)
  • necrosis (after vessel embolism);

Polylactic acid yarn

On the basis of polylactic acid produce material for filament
lifting. Today procedures are very popular.
bio-reinforcement and threadlifting using as material
polylactic threads. The basis of this method is a feature of our
of the body to remove foreign matter from the
connective tissue.


With the introduction of threads under the skin, they are enveloped in collagen
by fibers. After some time, the filaments decompose to carbon dioxide.
gas and water, and a strong collagen frame well “holds” the fabric still
for two years. Polymer filaments exhibit the same mechanism.
actions, like fillers based on it. Polylactic acid yarn
not only “stretch” and hold the fabric, but also start the process
neocollagenesis, activating metabolic processes in the dermis. Act
The threads in the skin are divided into two stages:

  • First stage;
  • final stage.

The initial stage lasts about 10 months. Polylaminate threads
have special notches that “get used” to the layers of the skin,
thus providing a powerful lifting.

In the final stage, the effect of the threads does not stop even after
biodegradation. Why is this happening? When introduced into the dermis
polylactic acid activates fibroblasts that produce
production of new collagen. New strong collagen serves in the future
natural frame and retains the effect for another few years.
