“I looked up a lot of before-and-after photos from just one Ritwo treatment because I was considering getting it,

but there wasn’t as much difference as I expected..”

Many people start by checking before-and-after photos when researching skin treatments.

However, Ritwo is a treatment whose effects are difficult to judge based on a single photo taken immediately after the procedure.

This is because it does not create an immediate visible change on the skin’s surface, but instead works by helping restore the dermal environment itself.

From now on, I will explain in detail why you should not draw definitive conclusions about Ritwo based only on photos after one treatment.

What is

Ritwo?

The principles and effects of Ritwo

Ritwo is an ECM skin booster based on acellular allogeneic dermis, in which cellular components have been removed from human-derived allogeneic dermis.

ECM stands for extracellular matrix.

Simply put, you can think of it as the components surrounding skin cells that support the tissue and create an environment in which the cells can function.

While typical regenerative treatments stimulate the skin to induce collagen production,

Ritwo directly injects this dermis-derived ECM into the skin, helping to supplement the damaged internal environment where density has decreased.

As a result, it may help with various concerns, including not only skin elasticity but also fine lines, pores, skin texture, and dryness.

The structure of ECM

However, it took a certain amount of time for the ECM components to enter the skin and function properly.

Therefore, it was not possible to fully judge the effects based only on before-and-after photos taken immediately after one treatment.

I will explain the reasons in more detail by dividing them into three main parts.

Reactions that occur in the skin after Ritwo treatment

  1. Time needed for skin regeneration

As mentioned earlier, the condition of the dermis did not change in just one day simply because the ECM components had been delivered to the skin.

Because the skin needs time to adapt to the new environment and continue its regenerative response, changes over time must be observed.

  1. Changes that are difficult to capture in photos

Subtle changes in skin texture, fine lines, pores, and the feeling of elasticity may not be clearly visible depending on the lighting and angle of the photographs.

  1. Swelling immediately after treatment

If a photo was taken immediately after the procedure, swelling caused by the treatment could also be mistaken for an effect.

Because this is an injection-based treatment, mild temporary swelling may appear immediately afterward.

You should not mistake the temporarily tightened appearance of the skin at this point for an actual regenerative effect.

When the effects appear

and how many treatments are appropriate

So, when do the effects of Ritwo begin to appear?

The various effects of Hongdae Ritwo

Although there are individual differences, changes with Ritwo often begin to appear gradually around one to two weeks after treatment.

After that, people often observe elasticity and density becoming more firmly established over the following two to three months.

The various components of Hongdae Ritwo

However, if this is your first Ritwo treatment, rather than judging the results immediately after just one session, the ECM dermal environment may be more likely to settle in more stably with approximately three repeated treatments at intervals of about three to four weeks, depending on your skin condition and response.

Therefore, if this is your first treatment, we recommend carefully discussing the appropriate number and intervals of treatments for your skin type through a thorough consultation with a medical professional.

If you want to assess the effects of Hongdae Ritwo, you should not simply look at before-and-after photos from one treatment.

You need to allow enough time to see how your skin texture, elasticity, pores, and other aspects change after the immediate swelling subsides.

Since your skin condition can look quite different depending on the angle and lighting of the photos, use testimonials only as a partial reference.

We strongly recommend that you consult with an experienced medical professional to learn in detail whether Ritwo would truly be helpful for you.
