Hello. I’m Dr. Jo Wonjin, and I’ve been seeing patients for 10 years.

They say it reduces fine lines and improves elasticity.

Can I use it instead of filler for nasolabial folds?

To get straight to the point, it’s hard to use it as a replacement for filler.

However, depending on the degree of wrinkles, you may see an effect where collagen is filled in and the nasolabial folds become less noticeable.

Lately, I’ve been getting a lot of questions about this procedure.

Under the topic, “Hongdae Re2O: Will It Work on My Face? Results, Pain, and Everything to Know,”

I’ll explain whether Re2O is right for your skin,

and what standards you can use to see results without wasting money.

The disappointment many people feel after a procedure

can be prevented to some extent just by knowing your skin condition accurately in advance.

  1. What are the effects of Re2O?

The biggest feature that distinguishes Hongdae Re2O from existing skin boosters is that it uses the actual components of our skin.

Many other skin boosters work by “stimulating” collagen production.

Re2O directly supplies actual skin components such as collagen and elastin.

It fills the thin, dry, and sunken skin foundation that comes with aging with real skin-building components, helping rebuild the skin from within.

One advantage of Re2O is that its components are similar to what originally exists in the body,

so the risk of rejection is very low and it blends naturally into the skin.

When the inside of thinned skin is densely filled in, you can expect overall fine lines to become less noticeable, skin texture to become smoother,

and dryness to improve as well.

  1. Re2O pain

One of the questions patients often ask in the clinic is:

“Since it’s injected, won’t it be too painful or leave marks for a long time?”

During Hongdae Re2O procedures, instead of a typical sharp injection needle,

a special needle called a “cannula,” which has a rounded tip and is thin, is mainly used.

Rather than repeatedly puncturing the skin surface,

the cannula is used to gently create a path in the deep dermal layer and spread the product evenly,

which greatly reduces concerns about pain and bruising.

Because the tip is rounded, the risk of damaging blood vessels or tissue inside the skin is also lower.

Also, since it is not injected shallowly into the superficial epidermal layer stitch by stitch,

the raised, bumpy “mosquito bite-like” marks right after the procedure are not very large.

The marks subside quickly after the procedure, so you can return to daily life soon.

  1. Will Re2O work on my face?

So, will Hongdae Re2O definitely work well for me too?

The reason people say, “My friend saw results, but I didn’t,” is that everyone has completely different skin thickness and concerns at the moment.

Re2O works by making the inner skin foundation healthy and dense.

It may create a slight amount of volume at first because material is being injected.

But it’s not over just because it’s injected; these components need to successfully integrate within the skin for it to become part of your skin.

So some of what is injected may lose a bit of volume afterward if it does not integrate well.

Therefore, if you want an immediate plumping effect like filler,

such as filling deeply etched nasolabial folds or a sunken forehead right away,

it may fall short of your expectations.

Also, if you currently have severe purulent acne or significant inflammation in the skin,

it is better to first treat and calm the inflammation rather than provide nutrients.

On the other hand, for those with thin, weak skin, fine lines all over, or severe inner dryness who want to strengthen the skin’s underlying structure,

this is where you can see the proper effect.

  1. How to get Re2O effectively

How can you increase satisfaction with Hongdae Re2O?

The key is to inject it into the correct layer in the proper amount.

Our face has different skin thickness in different areas.

Thin areas like under the eyes and the nasolabial fold, and relatively thicker areas like the cheeks, naturally require different injection depths and amounts.

If it is injected too deeply, the precious product can escape into the fat layer, causing the effect to drop significantly.

Because the design has to be different for each person and each area in order to fully bring out the product’s effect.

I explained this in more detail in the post below.

  1. Key takeaways on Re2O

To summarize what I discussed today,

Re2O is an effective procedure for directly strengthening and increasing the density of the skin’s foundation,

and the key is to accurately identify your skin thickness and adjust the injection depth accordingly.

If you skip this diagnostic process and proceed impulsively just because others are doing it too, you may end up wasting valuable time and money.

I hope this helps make skin improvement feel like a reasonable process rather than a difficult and burdensome choice.

Thank you. This was Jo Wonjin.
