re2O + 2 cc of filler

Hello, I am the director of 21 Plastic Surgery.

When looking at your smartphone, without even realizing it,

how much time do you spend with your head bent downward—

perhaps over the course of a day?

You may not notice it because it is an unconscious posture,

but repeated hundreds of times a day, from just a few seconds

to several hours at a time, this posture continuously creates

horizontal folds in the skin of the neck. When accumulated over

years, these folds become physically imprinted as wrinkles in the skin itself.

Neck wrinkles are a particularly frustrating change.

Even when you take good care of your skin and consistently care for your face,

your neck alone can reveal the passage of time first.

Even under the single name “neck wrinkles,”

there are usually two completely different changes

occurring together.

One is a decline in the skin’s own regenerative capacity.

As fibroblast activity decreases,

collagen and elastin synthesis also decline.

When cumulative UV exposure is added to this,

the skin gradually becomes thinner and drier,

with fine wrinkles settling across its surface.

Although many people apply sunscreen carefully to their faces,

there are actually many who do not extend that care to their necks.

Neck skin exposed every day without UV protection

can inevitably experience collagen damage at a much faster rate.

The other is the trace left on the skin by long-standing habits.

When looking down at a smartphone, the height of your pillow while sleeping,

and everyday habits are repeated for years,

horizontal lines can become physically etched deeply into the skin.

In such cases, regeneration alone cannot completely smooth them out;

an approach that also fills the grooves is needed.

Designing regeneration and filling together

*In simple terms, re2O can be thought of as an ingredient that sends a signal to the cells within the skin to “make collagen again.”

When the regenerative ingredient polyneucleotide (PN)

is delivered deep into the dermal layer,

fibroblasts—the worker cells that produce collagen

and elastin—begin to become active again.

It is similar to restarting a factory

that has been idle for a long time.

As a result, the thickness and elasticity of the neck skin as a whole

are fundamentally improved, making this especially suitable

for those with fine wrinkles spread broadly across the skin

or skin that is generally thin and dry.

However, re2O alone cannot completely fill

horizontal wrinkles that have already been deeply imprinted.

Filler is used to address this part.

A small amount is precisely injected in multiple layers

along the lines of the neck wrinkles.

Rather than adding a large amount at once,

the key is to carefully fill the deeper grooves,

while preserving the neck’s natural curves.

This helps prevent unnatural clumping

even when moving the neck,

and creates a smooth result when viewed

from any angle, whether front or side.

Depending on the severity of the neck wrinkles and the recovery time you prefer,

I also consider two additional treatments.

They are:

“Skin Botox and stem cells with PRP.”

Skin Botox involves finely dispersing botulinum toxin

into the superficial layers of the neck.

It helps relax subtle contractions of the superficial muscles,

slowing the rate at which wrinkles deepen again.

It can be particularly synergistic for types of neck wrinkles

in which repetitive muscle movement plays a significant role.

Stem cells and PRP involve concentrating platelets

and growth factors extracted from your own blood

and injecting them together.

The concept is to add growth factors to the regenerative environment

created by re2O, further improving the speed and completeness

of skin regeneration.

I do not recommend this combination in exactly the same way for everyone.

Taking into account the condition of the neck skin and the depth of the wrinkles,

as well as, above all, your preferred recovery time and schedule,

I carefully design only the combinations that are truly necessary

through consultation.

If the neck wrinkles in the photos keep catching your eye,

now may be a good time to receive an accurate evaluation.

Thank you^^
