Re2O Precautions: What You Must Know Before and After the Procedure

The ECM Booster ReTuO is a skin booster treatment targeting the environment deep within the skin, namely the extracellular matrix (ECM). To put it simply, this procedure is not designed to 'artificially add something new' to the skin, but rather to help revive its original elasticity and moisture retention capacity. That is why the core precautions are not complicated at all. Avoid disrupting the skin barrier before and after the procedure, and maintain the necessary conditions for recovery. That is virtually all there is to it.

However, 'looking simple' and 'doing whatever you want' are entirely different things. Even with the same procedure, the quality of the results varies depending on your skin condition, lifestyle habits, and post-procedure care. In this article, Gangnam Onlif Clinic outlines the precautions actually emphasized when performing ReTuO—plainly and honestly, without exaggeration or fearmongering.

🔎 What is the ECM Booster ReTuO?

The ECM is the structural network that fills the spaces between skin cells and supports them. It is easiest to think of it as the 'foundation' where components like collagen and elastin reside. As we age and the skin tires, this foundation loosens, leading to reduced elasticity, dryness, and shallow fine lines.

ReTuO is a skin booster focused precisely on this ECM environment. Rather than altering the skin surface, it takes an approach that refines the internal conditions so the skin can restore its own healthy state. It is a procedure that aligns seamlessly with Onlif's philosophy of 'removing the concerns that obscure your natural beauty.'

The reason we highlight this point first is clear: you need to understand what the procedure does to appreciate why such precautions are necessary.

📌 Key Summary: ReTuO is a skin booster that revives elasticity and hydration by targeting the skin's internal foundation (ECM), supporting the skin's inherent health without altering its facial contours.

⚠️ Precautions to Keep in Mind Before the Procedure

The results of a procedure are not determined solely in the treatment room. Your skin condition before entering accounts for half of the outcome.

• Avoid days when your skin feels feverish, flushed, or is experiencing breakouts: Under an inflamed state, the recovery response can be disrupted.

• Refrain from harsh exfoliation, scrubs, and high-concentration acid ingredients 2–3 days prior: Undergoing a procedure with a compromised skin barrier makes the skin overly sensitive to irritation.

• Avoid alcohol starting the day before: Vasodilation can lead to increased swelling and bruising.

• Notify us in advance if you are taking medications, especially blood thinners: These can affect bleeding tendencies and bruising.

• Check intervals if you have recently had other procedures (lasers, fillers, etc.): Adjustments are necessary to prevent cumulative irritation to the skin.

There is no need for overly elaborate preparation. Simply arriving without excessively agitating your skin that day is the best pre-treatment step.

📌 Key Summary: Avoid inflammation, exfoliation, and alcohol, and share your current medications and recent treatment history in advance to ensure much calmer skin on the day of the procedure.

🧴 Care from Right After the Procedure for the Next Few Days

For treatments like ReTuO that act deep within the skin, post-care over the subsequent few days essentially puts the finishing touches on the results.

What to Watch Out For Within the First 48 Hours

• Mild redness or a sensation of irritation can occur due to the nature of the procedure, and it usually subsides within a day or two.

• Wash your face gently with lukewarm water, without rubbing.

• Skip makeup on the day of the treatment if possible — give your skin time to stabilize.

• Moisturize generously. Since ReTuO aims to restore hydration and the skin barrier, moisturizing thoroughly at home works in synergy with the treatment.

Things Best Avoided for About a Week

The core principle of aftercare can be summed up in two words: 'soothing and hydration.' There is no need to overcomplicate it.

📌 Key Summary: Soothing within the first 48 hours, followed by avoiding heat, UV rays, and harsh ingredients for a week while focusing on hydration, is the key to recovery.

🙂 Which Skin Concerns Is It Best Suited For?

ReTuO is not a cure-all solution for every skin concern. It simply has specific concerns it is ideally suited to address.

• When skin loses elasticity and starts to feel noticeably saggy

• When skin is dry, rough in texture, and frequently feels tight deep within

• When troubled by shallow fine lines and a dull, lifeless complexion

• When seeking a natural, subtle restoration of skin condition rather than a dramatic lift

Conversely, if sagging has progressed significantly and requires robust lifting, rather than ReTuO alone, combining it with elasticity procedures such as All-Tight Lifting, thread lifting, HIFU, or radiofrequency is often considered. Because this assessment varies from person to person, the process of designing a treatment plan after directly evaluating the skin condition is crucial.

This is why Onlif emphasizes a 'physician specialty system'—different core concerns require distinct clinical approaches.

📌 Key Summary: ReTuO is well-suited for early loss of elasticity, dryness, and texture concerns; for advanced sagging, a combination plan with lifting procedures is more appropriate.

🧩 Be Sure to Check These During Your Consultation

As with all medical procedures, certain personal conditions require careful caution.

• If you are pregnant or breastfeeding

• If the treatment area has skin diseases, infections, or severe breakouts

• If you have a keloidal tendency or unusually slow wound healing

• If you have a history of allergies to specific ingredients

• If you regularly take specific medications

Rather than concluding that you 'cannot do it,' these conditions are matters of determining feasibility and adjusting timing together. It is always safest to disclose them openly beforehand.

📌 Key Summary: If you are pregnant, nursing, have skin conditions, keloids, allergies, or take routine medications, be sure to share this before treatment for a safe, tailored plan.

❓ Frequently Asked Questions

How many sessions of ReTuO are needed to see results?

It depends on your skin condition and goals. Generally, skin booster treatments offer the most stable results when built up over multiple sessions at regular intervals rather than just once. The optimal number of sessions and frequency are best determined after an in-person skin evaluation.

Can I return to daily life immediately after the procedure?

Generally, there are few restrictions on returning to daily activities, but it is recommended to avoid makeup, strenuous exercise, and alcohol on the day of treatment. Since mild redness may occur, we advise against scheduling the procedure one or two days before an important event.

When can I wash my face or apply makeup after the procedure?

You can wash your face gently with lukewarm water starting the same day, while it is better to wait until the next day to apply makeup once the skin has calmed down. If your skin feels sensitive, give it an extra day of rest.

Can it be combined with other procedures?

Yes, but combinations and sequences must be adjusted to prevent the skin from receiving excessive irritation all at once. Combining with lifting, HIFU, and other treatments is safely arranged by spacing them out according to your skin condition.

Can thorough moisturization alone achieve similar results?

While consistent at-home moisturizing is certainly helpful, it is fundamentally different from directly addressing the ECM environment within the skin. ReTuO works to refine that inner foundation, while home moisturization plays a supporting role in maintaining those effects for longer.

How long do the results last?

Individual variations are significant, and because skin aging is an ongoing process, results are not permanent. Maintaining your skin condition through periodic treatments is the most realistic approach, and longevity depends on individual factors.

Precautions for Taking Lithium: Things to Check Before Choosing a Clinic

Even for the same procedure, the results and recovery process vary depending on where, by whom, and how it is performed. Asking the following questions during your consultation can help guide your decision.

• Is this a treatment the clinic performs frequently? — Every clinic has its primary focus areas. Check whether they regularly handle precautions regarding lithium intake and procedures.

• Can you verify the products and equipment used? — Ask during the consultation whether you can verify the product names and authenticity (such as import approval and standard unboxing verification procedures).

• Is the cost breakdown clearly explained? — Rather than just hearing a total amount, you need to understand which products are used, how much, and across what area to make an informed choice.

• Is the plan designed looking at the entire face? — Even with the same treatment, placement and dosage vary according to facial shape, skin condition, and facial asymmetry.

• Are adverse reactions and recovery processes explained first? — Clinics that walk you through potential adverse effects and how to respond, rather than only highlighting expected improvements, make it easier to make an informed judgment.

• Is there a clear follow-up protocol after the procedure? — Check whether follow-up check-in schedules, emergency contact channels, and criteria for revisits are established.

How Onlif Clinic Approaches Precautions for Taking Lithium

• Specialized division of care — Guided by the belief that a single physician should not handle every treatment indiscriminately, Onlif divides medical care among dedicated doctors according to their specialized fields.

• Products and equipment verified together during consultation — We guide you through the products used and our unboxing verification process during your consultation.

• Costs explained with a breakdown after diagnosis — Because areas, dosages, and coverage vary per person, we clearly explain what costs apply to which components.

• Designed around the overall facial balance — We view the face through the three pillars of texture, balance, and youthful signals, planning treatments to refine the elements obscuring your natural features rather than altering your facial structure.

• Adverse reactions and recovery explained up front — Alongside the expected changes, we explain individual variations, possible side effects, and management steps prior to treatment.

• Post-treatment progress monitored together — If check-ins are needed during recovery, we provide guidance on follow-up visits and direct contact channels.

If you are considering precautions for taking lithium, it is best to first evaluate what is possible and what is not for your current state.
