Most patients need between 1 and 3 sessions of XERF, depending on the degree of skin laxity being treated and the result they are aiming for. Some see meaningful improvement from a single session.
Others, particularly those with more established laxity, benefit from a short series spaced a few weeks apart.
There is no universal number that applies to everyone, but there is a clear logic behind how the right number is determined.
When more than one session is recommended, treatments are typically spaced 4 to 6 weeks apart.
This interval is not arbitrary. Collagen remodelling from each session continues to develop over several weeks, and spacing sessions this way allows that process to progress meaningfully before the next treatment adds further stimulation.
Treating too soon does not accelerate results, it simply adds energy to skin that is still in the middle of remodelling from the previous session.
Collagen decline is a gradual process, which means the right approach shifts somewhat across different life stages. This is a helpful general guide, though your practitioner will always assess your actual skin condition rather than your age alone.
Late 20s to early 30s. Collagen production is generally still strong at this stage. A single session, used preventatively or annually, is often enough to support skin quality before visible laxity develops.
Mid 30s to 40s. This is when early to moderate laxity typically becomes more noticeable, particularly along the jawline and in the lower face. A short series of 2 to 3 sessions is common at this stage, often followed by an annual maintenance session.
50s and beyond. More pronounced laxity is common by this stage, and a series of 3 sessions is often recommended to achieve a meaningful result. Results remain gradual rather than dramatic, in keeping with how XERF works biologically, but noticeable improvement in firmness and definition is still achievable.
To understand more about what XERF can realistically achieve and who it suits best, read our guide on whether you are a good candidate for XERF.
For a single session, visible tightening begins within hours, with the fuller collagen-driven result developing over the following 3 to 6 months.
For patients completing a series of 2 to 3 sessions, the complete result of the whole series is typically visible within a similar timeframe once the final session has had time to take effect. For a detailed breakdown of the timeline and how long results last, read our guide on XERF results and how long they last.
Once your initial course of treatment is complete, most patients maintain their results with a single annual session, rather than repeating a full series.
This keeps collagen production consistently supported without the need for another intensive round of treatment, provided the initial laxity has been addressed adequately.
The ranges above are a genuinely useful starting point, but the right number of sessions for you specifically depends on a physical assessment.
At Dr Hass Clinic, Dr Hasaneen Al-Janabi assesses your skin quality, the degree of laxity present, and your goals before recommending a plan, rather than applying a standard number to every patient regardless of their anatomy.
