**A real question from a Dcard user**: “When getting glow injections in South Korea, Rejuran is available in both black and red packages, and the prices differ significantly. What are the differences in their effects? Should one choose the black package or the red package? Does anyone have any experiences to share regarding both options?
I clearly inquired about the differences between the Rejuran PN Black Box and the Red Box at the Gangnam clinic.
The first time I went to South Korea to receive glow injections, I was completely at a loss when I stood in front of Rejuran’s treatment menu: black box, red box, silver box, blue box… which one should I choose? The salesperson kept talking non-stop in Korean, but I didn’t understand a word, so in the end, I just picked one at random.
It was only after doing some in-depth research that I realized that the different colored boxes of Rejuran actually correspond to product lines designed to meet different needs. Today, let’s take a closer look at the differences between the black box and the red box.
Comparison table of the entire Rejuran series
| Products | Concentration | Main benefits | Suitable for various ethnic groups | pain sensation | Reference price |
|---|---|---|---|---|---|
| **Black box** | The thickest | Deep repair, anti-aging and firming effects | Dryness and peeling, fine lines, post-treatment care | medium | 250,000 to 400,000 yuan per 2 centum cores |
| **Red Box** | Sub-concentration | Surface moisturization and radiance | If you want a glossy finish and skin hydration before applying makeup | Mild | 200,000 to 350,000 yuan per 2 centum cores |
| **Silver Box** | ordinary | Basic moisturization | First attempt for beginners | Mild | 150,000 to 250,000 yuan per 2 centum cores |
| **Blue Box** | ordinary | Specifically designed for skin with acne-prone areas | Oily skin with enlarged Pores | medium | 180,000 to 280,000 yuan per 2 centum cores |
Is a “black box” right for you?
**The three core advantages of the black box**:
1. **Highest concentration of PDRN**: It boasts the strongest repairing properties among the entire series.
2. **Long-lasting moisturization**: The effects can last for 4 to 6 weeks after a single application.
3. **Anti-aging additional benefits**: Stimulates the proliferation of Collagen
**Who is suitable for choosing a black box procedure?**
- During seasonal changes, when the skin becomes dry and peels, nothing seems to work.
- After the laser treatment, you want to accelerate the recovery process.
- Those over 25 years old who want to start anti-aging treatments
- The skin looks dull and lacks glow.
The advantages of the red box
1. **Faster postoperative recovery**: With fewer papules than in the black box treatment, they usually disappear within 2 to 3 days.
2. **Relatively low price**: High cost-performance ratio
3. **More suitable for use before makeup**: The makeup will adhere perfectly after application.
**Who is suitable for choosing the Red Box?**
- For my first glow injection, I wanted to test the temperature of the solution first.
- Makeup tends to become powdery and cause peeling.
- I have a limited budget but would like to give it a try.
