High frequency facials are one of the most underrated yet powerful treatments in advanced skincare. Trusted by professional clinics for decades and loved for their instant results, high frequency technology is a game-changer for acne, ageing, congestion and dull skin. At Rènü Dermatology, high frequency facials are used as a results-driven standalone treatment or combined with other advanced facials to maximise skin health.
In this in-depth guide, we’ll explore what high frequency facials are, how they work, their skin benefits, who they’re suitable for, and why they remain a staple in professional aesthetics.
What Is a High Frequency Facial?
A high frequency facial is a professional skincare treatment that uses a high frequency electrical current delivered through a glass electrode. When the electrode is applied to the skin, it produces a gentle electrical current that interacts with oxygen, creating ozone. This ozone has powerful antibacterial, anti-inflammatory and oxygenating properties.
The treatment is painless, relaxing and non-invasive, making it suitable for a wide range of skin types and concerns.
High frequency technology has been used in professional skincare for over 100 years and continues to be a gold standard in acne and anti-ageing treatments.
How Does High Frequency Work?
High frequency works by delivering a safe, low-level electrical current through specialised glass electrodes filled with either neon or argon gas:
- Neon gas (orange/red light) – Used for anti-ageing, rejuvenation and circulation
- Argon gas (violet/blue light) – Used for acne and antibacterial treatments
When applied to the skin, high frequency:
- Oxygenates the skin cells
- Kills acne-causing bacteria
- Boosts blood circulation
- Stimulates collagen and elastin
- Reduces inflammation and redness
The result is clearer, brighter, firmer and healthier-looking skin.
Key Benefits of High Frequency Facials
1. Powerful Acne Control
One of the most well-known benefits of high frequency facials is their ability to treat acne effectively. The ozone produced during treatment has strong antibacterial properties, helping to destroy acne-causing bacteria (P. acnes).
High frequency also:
- Reduces active breakouts
- Helps prevent future acne
- Calms inflamed, angry skin
- Speeds up healing of existing blemishes
This makes it ideal for mild to moderate acne, hormonal breakouts and congested skin.
2. Anti-Ageing & Skin Firming
High frequency stimulates blood circulation and increases oxygen delivery to the skin. This encourages collagen and elastin production, which are essential for maintaining firmness and elasticity.
Benefits include:
- Reduced fine lines and wrinkles
- Improved skin tone and texture
- Firmer, plumper appearance
- Enhanced skin radiance
Over time, regular treatments can visibly rejuvenate ageing skin.
3. Improved Circulation & Oxygenation
By increasing blood flow, high frequency brings fresh oxygen and nutrients to the skin while helping remove toxins. This leads to:
- A healthy glow
- Improved cell renewal
- Faster healing
- Revitalised, energised skin
This makes it perfect for dull, tired or stressed skin.
4. Reduced Inflammation & Redness
High frequency has calming and anti-inflammatory effects, making it suitable for sensitive or reactive skin when used correctly by a professional.
It can help:
- Reduce redness
- Calm irritated skin
- Support healing post-extractions
- Strengthen the skin barrier
5. Enhanced Product Absorption
After a high frequency facial, the skin is oxygenated and stimulated, allowing serums and active ingredients to penetrate more effectively. This enhances the results of professional skincare products used during the treatment.
What Happens During a High Frequency Facial?
A professional high frequency facial typically includes the following steps:
- Skin consultation – Your therapist assesses your skin type and concerns
- Cleanse – Deep cleansing to remove makeup, oil and impurities
- Exfoliation – Removes dead skin cells to prep the skin
- Extractions (if needed) – Particularly beneficial for congested skin
- High frequency application – The glass electrode is gently glided or tapped over the skin
- Mask – Targeted to your skin’s needs
- Serum & moisturiser – To hydrate, protect and enhance results
The treatment is relaxing, with a gentle warming or tingling sensation.
Who Is a High Frequency Facial Suitable For?
High frequency facials are suitable for most skin types, including:
- Acne-prone skin
- Congested skin
- Oily or combination skin
- Ageing or mature skin
- Dull or tired skin
They are especially popular with clients who want visible results without downtime.
Who Should Avoid High Frequency Treatments?
While safe, high frequency is not suitable for everyone. Contraindications include:
- Pregnancy
- Pacemakers or heart conditions
- Epilepsy
- Metal implants in the treatment area
- Active rosacea flare-ups (depending on severity)
A full consultation is always essential before treatment.
How Often Should You Have High Frequency Facials?
For best results:
- Acne concerns: 1–2 treatments per week initially
- Anti-ageing & maintenance: Every 2–4 weeks
Your therapist will create a personalised treatment plan based on your skin goals.
High Frequency vs LED Therapy: What’s the Difference?
While both treatments target skin health, they work differently:
- High frequency uses electrical current to oxygenate and kill bacteria
- LED therapy uses light wavelengths to stimulate cellular repair
High frequency is often preferred for active acne and congestion, while LED therapy excels in healing and long-term rejuvenation. Many clinics combine both for optimal results.
Can High Frequency Be Combined With Other Treatments?
Absolutely. High frequency works beautifully alongside:
- Deep cleansing facials
- Hydrafacials
- Microneedling (post-treatment healing support)
- Chemical peels (when appropriate)
At Rènü Dermatology, high frequency is often used as a finishing step to calm the skin, reduce bacteria and accelerate healing.
Results: What Can You Expect?
After just one session, clients often notice:
- Reduced redness
- Calmer skin
- Fewer active blemishes
- A brighter, healthier glow
With regular treatments, results include:
- Clearer skin
- Improved texture
- Reduced breakouts
- Firmer, more youthful appearance
Why Choose a Professional High Frequency Facial?
