CoolJet™ Plasma
CoolJet™ is a non-thermal cold plasma device that delivers plasma energy deep into the dermal and subcutaneous layers of the skin without heat, without needles, and without surface damage. Cold plasma sits at the intersection of physics and skin science, and CoolJet™ is one of the most advanced delivery systems available. At DOSE, it's used as both a standalone treatment and a complement to other skin therapies for enhanced, longer-lasting results.
How It Works
Cold plasma is created when a gas is energised to the point where electrons are stripped from atoms, producing a highly reactive stream of charged particles. CoolJet™ channels this plasma energy into the skin via a specialised handpiece, penetrating the dermis without thermal injury. This stimulates collagen production, promotes cellular remodelling, enhances tissue regeneration, and creates an antimicrobial environment within the skin. Healthier, more functional skin from the inside out, not just surface-level improvement.
Who Is It For?
CoolJet™ is one of the most versatile and inclusive treatments on the DOSE menu. It suits clients dealing with:
- Fine lines and early signs of ageing
- Skin laxity and loss of firmness
- Pigmentation and discolouration
- Active acne and congested skin
- Rosacea, redness, and chronic skin inflammation
- Sensitivity and reactive skin conditions
- Anyone seeking a non-invasive, needle-free, no-downtime option
- All Fitzpatrick skin types including deeper tones. No heat means no risk of post-inflammatory hyperpigmentation
It's also an excellent option for clients who haven't tolerated other treatments well, or who want to complement their existing treatment plan without adding downtime.
Who Is It Not For?
CoolJet™ has very few contraindications, which is part of what makes it so accessible. It is not suitable for clients who:
- Have a pacemaker or implanted electronic device
- Are pregnant (as a precautionary measure, not due to known risk)
- Have active open wounds, infections, or broken skin in the treatment area
- Have certain metal implants in or near the treatment zone
If you have a complex medical history or are unsure about suitability, a consultation before booking is always recommended.
What to Expect
CoolJet™ is non-invasive, painless, and requires no downtime. You may feel mild warmth or tingling during treatment, nothing uncomfortable. The handpiece is passed over the treatment area in a precise, systematic pattern. Sessions take 30–60 minutes. Skin may appear slightly flushed immediately after, resolving quickly. You can return to normal activities the same day.
Sessions & Results
Results are both immediate and cumulative. For deeper concerns such as pigmentation, significant ageing, or acne a course of 4–8 sessions spaced twice a week is recommended. Maintenance every 6–8 weeks supports long-term skin health.
A Note on Skin Tone
CoolJet™ is one of the most inclusive advanced treatments available. No heat, no UV energy, safe and effective across all Fitzpatrick skin types, including deeper tones that may not be suitable for laser or IPL. Also safe for sensitive skin, rosacea, and reactive conditions.
FAQs
Is CoolJet™ painful? No. Most clients describe it as gentle warmth or mild tingling. No numbing cream required.
What makes CoolJet™ different from laser? Laser uses heat energy, which carries a risk of thermal injury and post-inflammatory pigmentation, particularly on darker skin tones. CoolJet™ uses cold plasma. No heat, no UV, no downtime, safe for all skin tones.
Is there any downtime? None. You may have mild flushing for an hour or two, but you can go straight back to your day.
Can CoolJet™ be combined with other treatments? Yes and it works beautifully in combination. It's frequently used alongside skin needling, chemical peels, or LED to enhance results and support healing.
How many sessions will I need? For general skin health, 4 sessions is a strong starting point. For more targeted concerns, 6–8 sessions may be recommended. Brittni will advise after assessing your skin.
