Understanding the science
At its core, diathermy works by delivering a controlled electrical current through a very fine probe. When this current reaches the skin, it generates heat at a highly localised point.
This heat has a specific effect depending on the type of lesion being treated. It can:
- Seal small blood vessels, as in the case of thread veins
- Break down excess or raised tissue, such as skin tags
- Disrupt the structure of superficial lesions like milia
Because the energy is so precisely delivered, the surrounding skin remains largely unaffected. This is what allows diathermy to be both effective and controlled, even in delicate areas.
A treatment grounded in control
One of the strengths of diathermy is its simplicity. There are no broad fields of energy or deep tissue changes. Instead, the treatment focuses only on what needs to be addressed, making it particularly suited to small, well-defined concerns.
At Mirabel Clinic, this precision is combined with careful clinical assessment. Not every lesion should be treated in the same way, and part of the process is understanding exactly what is being treated before any intervention takes place.
What the skin does afterwards
Following treatment, the skin begins a natural healing process. The treated area may darken slightly or form a small crust. This is not damage, but part of how the skin repairs itself.
Over the following days, the skin renews and the lesion reduces or disappears, revealing a clearer surface beneath. The process is gradual and controlled, allowing the skin to recover in its own time.
Why experience matters
Although diathermy is a straightforward technique, outcomes depend heavily on how it is applied. The level of energy used, the duration of contact and the accuracy of placement all influence how the skin responds.
A measured, conservative approach helps to ensure that the treatment is effective while maintaining the quality of the surrounding skin. This is particularly important in visible or sensitive areas, where subtlety is key.
A reliable option for everyday concerns
Diathermy remains a widely used treatment because it is reliable, adaptable and well understood. It does not aim to change the skin, but to remove or reduce what is not needed, allowing the natural surface of the skin to come through.
For many people, it offers a straightforward solution to concerns that might otherwise persist. With careful assessment and precise application, it can be a simple and effective way to restore clarity and balance to the skin.
