In short. The gradual route rewards patience and punishes deadlines. Who tends to do well on it, who is frustrated by it, and the question that separates the two.

Key points

  • Ask yourself what you would conclude if very little were visible at six weeks.
  • If the answer is that the treatment has not worked and more should be added, this class will frustrate you, because six weeks is too early to conclude anything and adding at that point is the one decision that cannot be reconsidered.
  • If the answer is that six weeks is too early to judge, the route suits you.

The gradual route is not simply a slower version of a fast one. It asks for a temperament and a calendar, and it is a good fit for some patients and a reliably bad one for others.

Who tends to do well on it

The patient with nothing to prepare for does best, because nothing about the result has to be explained on a particular date. So does someone who wants a conservative first step and can accept being deliberately under-corrected, knowing that the review is where the next decision is taken. The pattern behind all of these is the same: the route rewards people who judge a change over months and who treat the first session as the beginning of a plan.

The single most useful question

Ask yourself what you would conclude if very little were visible at six weeks. If the answer is that the treatment has not worked and more should be added, this class will frustrate you, because six weeks is too early to conclude anything and adding at that point is the one decision that cannot be reconsidered. If the answer is that six weeks is too early to judge, the route suits you.

Who is frustrated by it

Anyone who wants to see a result before committing further is frustrated by a class that shows its result at the end of a course. Anyone who wants to trial a treatment and undo it if they dislike it is frustrated by a class with no dissolving agent. Anyone with a date in the diary is frustrated by a change that arrives in months. In a class that accumulates and cannot be reversed, a patient already certain that more is needed at every review is the one most likely to end up past the ceiling.

Where the route is simply the wrong answer

Where the complaint is the surface of the skin rather than volume, a stimulating material or a resurfacing treatment answers the question and this class does not. Where the face has descended, extra volume makes descended tissue heavier rather than lifting it, and an operation addresses the actual change. And where the honest answer is that nothing needs to be done, no temperament makes a course the right plan.

The route does not suit you if

  • You need to see the result before you commit to the rest of the course.
  • You would want the option of undoing it if you changed your mind.
  • You have a date within a few months that the result has to be ready for.

What protects a patient who does proceed is the record of what was placed, which is the subject of Why Records Matter More in a Non-Dissolvable Class. How the end of a course is planned rather than drifted into is set out in Stopping a Course: What Happens When You Stop.

Frequently asked questions

Am I a good candidate if I have a date in the diary?

Usually not for this class. A wedding, a reunion or a photograph in six weeks needs something that shows sooner or that can be adjusted late, and this class does neither. The same face might be a good candidate in a year with no date attached, which is why the calendar is part of the assessment rather than a detail.

I want to try it and stop if I do not like it. Is that possible here?

You can stop at any point, and stopping needs no taper. What you cannot do is remove what has already been placed, so the trial you are describing belongs to a class that can be dissolved. Someone who wants to see a result before committing further is describing a different treatment rather than a cautious version of this one.

Does wanting only a small change make me an easier patient?

Often yes. A patient who wants a conservative first step and can wait for the review to say whether more is wanted is well matched to a class that is judged over months. The difficult version of the same request is wanting a small change immediately, because that combines the slowest route with the shortest patience.

Risks & Limitations

  • There is no dissolving agent for this class. Injected collagen is absorbed over months but cannot be neutralised or removed by an injection, so a result you want less of is addressed later, in part, and by other means.
  • Lumps and nodules can appear weeks or months after a session. The timing is part of how they are assessed, and the answer is not another injection to dissolve the material, because for this class no such injection exists.
  • The change is gradual and it is not lasting. The material is absorbed at a rate that varies between people, no interval can be promised in advance, and a course repeated across years accumulates in a class that cannot be reversed.
  • Injection carries the ordinary risks of any injectable, including bleeding, bruising, infection and irregularity, and the rare vascular event that belongs to material placed into the face. A history of cold sores can be reactivated by treatment in the same area.

When to Seek Care

  • Severe pain out of proportion to the injection, or tissue turning white, grey, mottled or dusky, requires immediate assessment.
  • Any change in vision, including blurring or a patch of lost sight, requires emergency care.
  • A lump, firmness or a change in contour appearing months after a session should be reported when it appears, not at the next scheduled appointment.
  • Redness, heat, pain or discharge at a treated site, or fever with any of those, needs prompt assessment.
