Hello. Opening the window of confidence through dermatology. My Beauty Partner, Chang Dermatology Clinic.

Concerns about skin are something anyone can have, regardless of gender or age.

Especially during winter, when cold winds blow, dry weather can make skin concerns even more serious.

When skin becomes dry, aging also progresses quickly, and because it is not easy to improve with personal care alone, you may end up looking into effective procedures.

What procedure is suitable for complex skin concerns?

In general, the skin does not have only one concern; various symptoms appear at the same time.

Among them, as we age, different signs of aging such as wrinkles, skin sagging, and loss of facial contour appear, and the main cause of these symptoms is ECM.

ECM can be described as a collection of elements that maintain skin structure, such as collagen, elastin, and hyaluronic acid.

The procedure introduced today is the Gangnam ReTuO treatment, which directly injects these ECM components into the skin to bring about a satisfying change.

What is the ReTuO procedure?

ReTuO is a skin booster-type procedure. Traditional skin boosters helped active ingredients support the regeneration of collagen and other components within the skin.

This procedure goes a step further by improving the skin structure itself and directly supplementing the components needed by the skin.

In particular, a major feature is that the ingredients used in the procedure are human-derived allogeneic dermis.

Thanks to the characteristics of these ingredients and the strong effects they produce, it is a procedure that many people are interested in.

What is human-derived allogeneic dermis?

Human-derived allogeneic dermis, called hADM, is what remains after cells, fat, and other components are removed from donated dermis, leaving only the ECM.

Because it is allogeneic dermis with the cells removed, it does not trigger an immune rejection response, making it stable, and because only the ECM remains, it can produce even stronger effects.

If the existing principle helped restore elasticity by supporting ECM regeneration, ReTuO restores elasticity by injecting the ECM itself into the skin.

Rather than simply adding moisture or stimulating cells, it restores the skin structure that has collapsed due to aging, making more satisfying results possible.

What kind of changes can you expect?

Gangnam ReTuO has the advantage of providing multiple effects rather than just one.

As the dermal layer is reinforced and elasticity is replenished from the deeper layers of the skin, you can achieve firmer skin, and it is also effective in reducing enlarged pores that have become stretched.

In addition, the overall skin texture becomes smoother, wrinkles and fine lines may be softened, and the complexion may appear brighter.

As collagen is generated, it helps create firmer skin and can also support the skin’s natural healing ability.

Why has it become such a popular choice?

Another reason more people have recently been choosing Gangnam ReTuO is that the downtime is short.

These days, there is a high demand for immediate results and short downtime, so when choosing a dermatology procedure, these factors are considered very important.

ReTuO has the advantage of short downtime, making it comfortable even for office workers who cannot take a long recovery period or for people with important schedules coming up.

Because there is less worry about swelling, embossing, redness, or injection marks, and daily life can resume quickly, it is a procedure chosen by more people.

Who is this procedure suitable for?

Gangnam ReTuO is recommended for people who have multiple skin concerns such as elasticity, fine wrinkles, and skin texture.

It can also be a suitable option when you want natural volume or immediate results.

ReTuO is also recommended when you need not only improvements in visible skin texture, skin tone, and wrinkles, but also relief from inner dryness and strong hydration.

It will be a satisfying option for those looking for natural results, stable ingredients, and long-term care.

How long do the results last?

The duration may vary from person to person depending on individual skin characteristics, the environment, and whether proper care is maintained.

In general, it is recommended to undergo the procedure at least three times at intervals of about one month.

Through repeated Gangnam ReTuO treatments like this, the results can last about 6 months to over 1 year, and the specific repeat schedule should be customized according to each person’s characteristics.

How should you care for your skin after the procedure?

After the Gangnam ReTuO procedure, you should avoid heavy drinking and smoking, and avoid hot and humid environments such as jjimjilbangs or saunas.

It is also recommended to stop vigorous sports activities that may raise the temperature of the face for about one week.

In addition, thorough moisturizing care should be maintained to prevent the skin from becoming dry, and sunscreen should be used when going outside.

Temporary embossing or swelling may occur, but this is a natural phenomenon that will gradually subside over time.

Today, we introduced the ReTuO procedure, which has recently been receiving a lot of attention.

When undergoing the procedure, each person’s skin should be carefully diagnosed and a customized care plan established accordingly.

If you are concerned about signs of aging, complex skin care, or skin that feels rough and sensitive during winter, we hope you will achieve satisfying results through ReTuO.
