Collagen Booster Re2O: 6 Things You Should Know Before Treatment

If skin elasticity and texture are on your mind, you've likely come across collagen boosters. Here are the questions we hear most often during Re2O consultations at Kim Jongseo Plastic Surgery (Apgujeong, Seoul).

1. What kind of treatment is Re2O?

Re2O is a regenerative program that injects ingredients supporting collagen production into the skin, encouraging elasticity and texture to improve from within. Rather than immediate volume, the goal is to improve the skin's own condition.

2. How is it different from filler?

While filler focuses on adding volume, a collagen booster is aimed at improving skin elasticity, texture, and fine lines. Because the goals differ, the right treatment depends on your specific concern.

3. How many sessions do I need?

A typical course is around 3 sessions spaced 2–4 weeks apart, with ongoing maintenance afterward depending on your skin condition. The exact plan is determined after an in-person consultation.

4. What's the process and how long does it take?

The process follows consultation → numbing cream → injection, and generally takes around 30 minutes. Temporary redness or swelling at the injection sites may occur right after treatment and usually subsides within a few days, though this varies by individual.

5. How should I care for my skin afterward?

Avoid excessive alcohol or sauna use on the day of treatment, and we recommend moisturizing and sun protection. Detailed aftercare instructions are provided after the procedure.
