Why Do Blisters Appear After Cupping?
Cupping therapy is a traditional healing method that has been used for thousands of years in Traditional Chinese Medicine (TCM). Most people are familiar with the circular red or purple marks left after a session — but sometimes, small blisters or fluid-filled bubbles can also appear on the skin. While this may look concerning at first, it’s a known reaction and usually not a cause for alarm.
What Causes Blisters During Cupping?
Blisters can form for several reasons, especially when the skin undergoes strong suction or heat. Common factors include:
🔹 Cups left on too long
Everyone’s skin responds differently. Some people may develop blisters after just a few minutes of suction, while others may not react even after longer sessions. Practitioners should adjust treatment time based on individual tolerance.
🔹 High temperature on the cups
In fire cupping — where heat is used to create suction — cups can sometimes get too hot. Excessive heat can irritate the skin and lead to blister formation.
🔹 Thin or sensitive skin
Areas of the body with more delicate skin are more likely to show blisters or bubbles after cupping.
🔹 Strong suction or heavy cupping
If the suction level is too strong for a person’s skin tolerance, fluid can collect under the top layer of skin, causing blistering.
Are Blisters Harmful?
Blisters from cupping may look dramatic, but they’re generally harmless. They often heal on their own as the skin recovers. However, it’s still important to watch for signs of irritation or infection and care for the area properly.
How Can You Prevent Blisters?
Here are ways to help reduce the chance of blistering:
✔ Ask for shorter suction time during your session
✔ Choose gentler cupping methods (e.g., silicone cups)
✔ Avoid intense suction on sensitive skin
If you’re doing cupping at home, always start with mild suction and monitor your skin closely.
What to Do If Blisters Appear
If blisters occur:
- Keep the area clean and protected
- Avoid popping blisters unnecessarily
- Seek medical advice if they become painful, warm, or increasingly red (signs of infection)
Final Thoughts
Blisters after cupping are a known skin response that may occur due to suction, heat, or individual sensitivity. In most cases, they are temporary and harmless. If you’re new to cupping or unsure how your skin may react, it’s always best to consult a trained therapist or healthcare professional. Choosing the right cups from a trusted supplier is also an essential first step in starting your cupping journey safely and confidently.
