One of the important ingredients for maintaining skin elasticity and health is collagen.

If you are interested in skincare even a little, you probably already know how important collagen is.

Collagen is an essential protein that makes up about 70% of the dermis, and it affects not only the skin but also the joints, blood vessels, and muscles.

However, as we age, our bodies can no longer produce collagen as quickly as it is lost.

Our body’s collagen begins to decrease in our late 20s, and after our 30s, it declines rapidly.

When collagen decreases, the skin loses elasticity and becomes more prone to wrinkles.

As elasticity declines, the skin not only develops wrinkles but also gradually sags under the influence of gravity.

This is why jowls appear as we age, or why the eyelids droop.

To keep the skin elastic, sufficient collagen is needed.

However, because natural production decreases, it needs to be supplemented from the outside.

Collagen Booster Injections

Collagen booster injections are a procedure that induces new collagen production by injecting ingredients directly into the skin that promote collagen generation.

Ingredients such as PDLLA and PLLA stimulate the skin tissue and help promote the body’s own collagen synthesis.

As these ingredients work deep within the skin, they can help promote skin regeneration, increase skin density, and improve elasticity.

Collagen boosters are generally recommended around the 30s, when skin aging begins in earnest.

However, if you are noticing fine lines or your skin feels easily dry and less elastic, you can undergo the procedure regardless of age.

Many people also seek collagen boosters to increase volume using collagen.

Unlike fillers, they increase volume by using your own collagen, so they can create volume in a relatively natural and safe way.

That said, fillers use a gel-like substance made of hyaluronic acid and similar ingredients, so they can create volume immediately and help shape the desired contour.

In comparison, the volume-enhancing effect of collagen boosters develops somewhat gradually.

However, collagen boosters are not only intended to increase volume, but also to improve the skin at a more fundamental level.

They work deep within the skin to stimulate collagen production, increase skin density, and strengthen overall elasticity.

Because of this, you can expect natural and long-term skin improvement.

PDLLA collagen booster injections are one of the representative procedures that promote collagen production in the skin, and they are collagen boosters whose main ingredient is Poly-D, L-Lactic Acid.

After being injected into the skin, PDLLA slowly breaks down and stimulates the dermis, inducing the production of new collagen.

The biggest feature of PDLLA collagen boosters is that they are made in the form of microspheres.

Because of this, they can be evenly injected into the skin, resulting in relatively less irregular volume formation or lumping.

Over time, the skin becomes firmer and denser, and they are especially helpful in improving thin skin to make it thicker and healthier.

Collagen booster injections are a procedure that induces collagen production within the skin.

You should carefully check which product is used, whether the medical staff have a sufficient understanding of skin structure, and whether the correct procedure is being followed.

PDLLA, PLLA, and similar ingredients used in collagen booster injections are substances that act over a long period in the deeper layers of the skin,

so if they are injected indiscriminately without considering the skin layers, there is a possibility of side effects such as nodules, inflammatory reactions, and asymmetry, so special caution is needed.

For this, the experience and skill of the medical staff are important.

Since the key point of collagen booster injections is not immediate results but the process by which the skin gradually improves over time,

we hope you choose a clinic that fully understands this, carefully diagnoses your individual skin condition, and can provide a procedure suited to it.

Ingredients such as PDLLA have the advantage of naturally making the skin firmer over time.

To achieve satisfactory results, we recommend that you receive 충분한 consultation from an experienced medical professional and proceed carefully.
