CoolJet™ Needle-Free Rejuvenation - The future of non-invasive skin health.

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 is a state-of-the-art technology sitting 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 a point where electrons are stripped from atoms, creating a highly reactive stream of charged particles. CoolJet™ channels this plasma energy into the skin using 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. The result is healthier, more functional skin from the inside out; not just surface-level improvement.

What to Expect

CoolJet™ treatment is non-invasive, painless, and requires no downtime. You may experience a mild warmth or tingling sensation during treatment; nothing uncomfortable. The handpiece is passed over the treatment area in a precise, systematic pattern. Sessions typically 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 from CoolJet™ are both immediate and cumulative. Most clients notice improved radiance and reduced redness after a single session. For deeper concerns (pigmentation, significant ageing, or acne) a course of 4–8 sessions spaced 2–4 weeks apart is recommended. Maintenance treatments every 6–8 weeks support long-term skin health.

A Note on Skin Tone

CoolJet™ is one of the most inclusive advanced skin treatments available. Because it uses no heat and no UV energy, it is safe and effective across all Fitzpatrick skin types; including deeper tones that may not be suitable for laser or IPL. It is also safe for sensitive skin and those with rosacea or reactive conditions.

Frequently Asked Questions

Is CoolJet™ painful?

No. CoolJet™ is one of the most comfortable advanced treatments we offer. Most clients describe it as a gentle warmth or mild tingling. There is no pain and 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, and safe for all skin tones.

Is there any downtime?

None. This is a truly no-downtime treatment. You may have mild redness for an hour or two, but you can go about your day immediately after your session.

Can CoolJet™ be combined with other treatments?

Yes and it works beautifully in combination. CoolJet™ is 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 and maintenance, a course of 4 sessions is a strong starting point. For more targeted concerns, 6–8 sessions may be recommended. Brittni will advise after assessing your skin.
