PRX-T33 peel has become one of the most talked-about skin treatments in aesthetic medicine, and for good reason. It delivers meaningful skin regeneration results without needles, without visible peeling and without significant downtime. But what exactly is it, how does it work, and is it the right treatment for your skin?
In this guide, Dr Effie Flourentzou, GMC-registered doctor and founder of Epitomi Aesthetics in Epsom Downs, explains the science behind PRX-T33. Who it’s suitable for, and what you can realistically expect from treatment.
What Is PRX-T33?
PRX-T33 is a professional bio-revitalisation treatment developed by the Italian company WiQo Med. Despite being categorised alongside chemical peels, it is neither a conventional peel nor an injectable.
It is applied to the skin as a topical gel. It penetrates deep into the dermis. It stimulates collagen production. It supports the skin’s natural cell renewal process. It does this without visible surface peeling. Traditional chemical peels often cause that peeling.
The treatment is needle-free and pain-free. It suits all skin types and tones, including darker complexions. These complexions are often seen as higher risk for chemical peels.
How Does PRX-T33 Peel Work?
PRX-T33 works through a combination of three active ingredients:
- 33% TCA (trichloroacetic acid): TCA stimulates the deeper layers of the skin, triggering a controlled wound-healing response that promotes collagen synthesis and skin regeneration. At this concentration, it is highly effective at reaching the dermis without causing surface damage.
- Hydrogen peroxide: This is the key differentiator of PRX-T33. Hydrogen peroxide neutralises the surface activity of the TCA, preventing the outer layer of skin from being damaged or visibly peeling. This is why the treatment produces deep regenerative effects with virtually no downtime.
- 5% Kojic acid: Â Kojic acid inhibits melanin production, helping to brighten the skin, improve skin tone and reduce the appearance of pigmentation. This makes PRX-T33 particularly effective for patients with uneven skin tone, sun damage or post-inflammatory hyperpigmentation.
Together, these three ingredients improve skin hydration and overall skin quality. They also support collagen production and stimulate cell renewal.
What Skin Concerns Does PRX-T33 Peel Treat?
PRX-T33 is a versatile treatment that can address a wide range of skin concerns. It is suitable for all skin types and particularly effective for:
- Skin laxity and loss of firmness – stimulates collagen to improve skin elasticity and structure
- Fine lines and early signs of ageing – improves skin quality and hydration at a dermal level
- Uneven skin tone and pigmentation – kojic acid brightens and balances skin tone
- Dullness and lack of radiance – bio-revitalisation restores glow and vitality to tired skin
- Acne-prone skin – the treatment has mild antibacterial properties and can help improve skin texture in acne-affected patients
- Rosacea and sensitive skin – because PRX-T33 does not cause visible peeling, it is more tolerable for reactive skin types than conventional chemical peels
- Stretch marks and scarring – the deep TCA stimulation supports skin regeneration in affected areas
It suits all skin tones, which is a key clinical advantage over stronger chemical peels. These peels have a higher risk of post-inflammatory hyperpigmentation in darker skin.
What Results Can You Expect from PRX-T33?
Results from PRX-T33 are often visible right after treatment. Patients often notice brighter, smoother skin within 24 to 48 hours. The skin appears more hydrated, luminous and refreshed.
Over the following days and weeks, as the deeper processes of collagen stimulation and skin regeneration continue, further improvements in skin firmness, tone and overall quality become apparent.
Realistic results from a course of PRX-T33 treatments include:
- Improved skin texture and smoothness
- Brighter, more even skin tone
- Reduction in fine lines and surface wrinkles
- Improved hydration and plumpness
- Reduction in the appearance of pigmentation
Before and after results vary depending on the individual patient’s skin condition, the number of treatments undertaken and aftercare compliance. Dr Effie will provide an honest assessment of what you can expect during your consultation.

How Many PRX-T33 Peel Treatments Do You Need?
A single PRX-T33 treatment produces visible results, but a course of treatments delivers the most significant and lasting improvement. In clinical practice, a course of three to five treatments is typically recommended, spaced one to two weeks apart.
After the first course, you can get maintenance treatments every two to three months. These treatments help keep your results. They also support your skin’s natural regeneration.
Dr Effie will recommend a personalised treatment plan based on your skin concerns, skin type, and desired results.
What Is the Downtime After PRX-T33?
One of the main advantages of PRX-T33 over conventional chemical peels is the minimal downtime. Because hydrogen peroxide prevents surface damage to the skin, there is no visible peeling and no significant recovery period.
Immediately after treatment, the skin may appear slightly pink or flushed. This typically settles within a few hours. Most patients return to their normal activities the same day, including work and social engagements.
PRX-T33 is often described as a lunchtime treatment. It can be done in under an hour with minimal to no downtime.
PRX-T33 Side Effects – What to Know
PRX-T33 has a well-established safety profile and is considered a low-risk treatment when performed by a trained professional. Reported side effects are generally mild and temporary:
- Transient redness or flushing immediately after treatment (usually resolves within hours)
- Mild sensitivity in the treated area for 24–48 hours
- Occasional mild itching or tingling during application
Serious complications are rare. Because the treatment does not break the skin’s surface, the risks associated with open-skin procedures do not apply. The needle-free nature of PRX-T33 also removes the risks associated with injectable treatments.
As with any professional skin treatment, it is important that PRX-T33 peels are performed by a qualified practitioner with appropriate training.
At Epitomi Aesthetics, all treatments are carried out by Dr Effie Flourentzou, a GMC-registered medical doctor.
PRX-T33 vs BioRepeel – What’s the Difference?
BioRepeel is another TCA-based professional skin treatment frequently compared to this formulation. Both stimulate skin regeneration and are positioned as low-downtime alternatives to traditional chemical peels. Here’s how they compare:
| PRX-T33 | BioRepeel | |
|---|---|---|

How Much Does PRX-T33 Cost in the UK?
PRX-T33 treatment costs vary between clinics depending on location, the practitioner’s qualifications and the number of sessions included. In London and the South East, single session prices typically range from £150 to £300.
At Epitomi Aesthetics in Epsom Downs, pricing and treatment plans are discussed at consultation, where Dr Effie can assess your skin and recommend the most appropriate course of treatment for your goals and budget.
Is PRX-T33 Worth It?
For patients who want better skin, treat early ageing signs, fix pigmentation, or restore radiance, PRX-T33 works well.
It avoids the downtime and risks linked to more aggressive treatments.
Its needle-free delivery, suitability for all skin types and tones, and minimal recovery period make it one of the more accessible and versatile professional skin treatments available. The results from a properly administered course are clinically meaningful and well-supported by patient outcomes.
As with any treatment, results depend on the skill of the practitioner and the suitability of the treatment for your specific skin concerns. A consultation with a qualified medical professional is the right starting point.
Frequently Asked Questions
What does PRX-T33 stand for?
PRX-T33 stands for the treatment’s primary active ingredient – 33% trichloroacetic acid (TCA) combined with hydrogen peroxide and kojic acid. It is manufactured by WiQo Med, an Italian medical aesthetics company.
Is PRX-T33 peel painful?
PRX-T33 is a pain-free treatment. Patients may experience a mild tingling or warming sensation during application, but this is generally well tolerated. No numbing cream is required.
Can PRX-T33 be combined with other treatments?
Yes. PRX-T33 is often combined with microneedling to improve results. The two treatments work well together. Microneedling creates tiny channels in the skin. These channels help PRX-T33 penetrate deeper. It can also be used alongside other skin treatments as part of a broader programme. Dr Effie will advise on combination options at your consultation.
How long do PRX-T33 results last?
Results from a course of PRX-T33 treatments can last several months. Maintenance treatments every two to three months are recommended to sustain and build on results over time. Individual longevity varies depending on skin type, lifestyle and aftercare.
Is PRX-T33 suitable for sensitive skin?
Yes. PRX-T33 is suitable for all skin types, including sensitive and reactive skin. Because the treatment does not cause visible peeling or surface damage, it is better tolerated by sensitive skin than most chemical peels.
Can the peel be used on the body?
Yes. While PRX-T33 is most commonly used on the face, it can also be applied to the neck, décolletage, hands and body areas affected by stretch marks or skin laxity.
