Diathermy is a trusted clinical treatment used to address a range of benign skin concerns on the face and body. With over 100 years of use in professional practice, it remains a go-to option for treating common superficial irregularities such as spots, lumps, and bumps.
Diathermy is suitable for clients seeking to address lesions, such as skin tags, sebaceous hyperplasias, seborrheic keratosis, Dermatosis Papulosa Nigra (DPN), angiomas, vessels, milia and other unwanted flat or raised benign lesions.
Diathermy treatments may not be suitable if any of the following apply
Pregnancy.
Metal pins or plates in the treatment area.
Medications, such as oral isotretinoin, oral steroids and blood-thinning medications.
Immune-compromised conditions, such as HIV, lupus and poorly managed diabetes.
Predisposition to keloid formation, excessive scarring and post-inflammatory hyperpigmentation.
Active cold sores, skin cancer, active infections, open wounds and burns.
Heart conditions, including electrical implants or pacemakers.
Inability to take downtime or undergo discomfort
Diathermy is a byproduct of radiofrequency energy that generates heat when applied to the skin via a fine probe. This heat is directed to the targeted lesion, where it works to coagulate or cauterise the tissue. It can be used on various benign lesions across the face and body.
Clients often describe the sensation as a brief zap or sting, sometimes accompanied by a feeling of warmth in the treatment area.
To ensure the best possible outcome from your Diathermy treatment, please follow the guidelines below.
The treatment area must be free of both natural and artificial tan.
If you are prone to cold sores, consider using an over-the-counter antiviral prophylactic to minimise the risk of a breakout.
Discontinue any topical Vitamin A (retinol) products at least two weeks before your appointment.
A skin cancer check must have been completed within the last 12 months before treatment.
If you have any questions or need clarification, our team is here to guide you.
For the first five days post-treatment, or until all post-treatment skin reactions have fully settled, it’s important to support your skin with the following care.
Use only a gentle cleanser morning and night.
Apply a moisturiser or your prescribed post-treatment product as directed.
Avoid direct sun exposure. When outdoors, wear a broad-brimmed hat and apply (and reapply) SPF 50 sunscreen throughout the day.
Refrain from vigorous exercise, saunas, steam rooms, or any heat-based wellness treatments for at least 48 hours.
Avoid picking or prematurely removing tissue from the treated area.
Following these guidelines will help optimise your results and support a smooth recovery.
Downtime typically lasts five to seven days, depending on the treatment area. During this time, you may experience.
Mild to moderate scabbing, Redness, Swelling.
In some cases, larger skin tags may take up to two weeks to naturally detach. Your clinician will follow up after your first session, and we encourage you to contact the clinic if you experience any responses that are outside of the expected range.
Results, downtime and treatment response will vary from person to person
One to two treatments may be recommended, spaced four to six weeks apart, followed by a review. Your clinician will assess your skin and concerns to determine the appropriate treatment plan, which will be discussed in detail during your consultation.
