In short. Lines that show only on movement, a normal change for the person's age, and an expectation no option meets. The cases where the honest answer is to do nothing.

Key points

  • Before deciding anything, spend a fortnight doing the boring steps: a gentle cleanser, a moisturiser that suits you, and daily sun protection.
  • Photograph your face in the same light at the start and the end.
  • Lines that are hydration will have moved.

This site exists to explain options, and part of that is saying when none of them should be used. There are four situations in which the honest answer to a question about fine lines is to do nothing.

Lines that appear only on movement

A face that creases when it smiles, frowns or squints is behaving normally. Nothing about that requires treatment, and the only thing available addresses the muscle that makes it. Leaving a movement line alone is a legitimate choice rather than a failure to look after yourself.

A change that is normal for your age

Lines appear in everyone, and the range at any given age is wide because it depends on genetics, sun history and habits. Skin that is doing what skin does at that age is not a problem to be solved.

A test worth running for two weeks first

Before deciding anything, spend a fortnight doing the boring steps: a gentle cleanser, a moisturiser that suits you, and daily sun protection. Photograph your face in the same light at the start and the end. Lines that are hydration will have moved. Lines that are structural will not have, and knowing which you are looking at changes the whole decision.

An expectation that no option meets

Some people want their lines gone rather than softened, a result that holds without maintenance, or a face that reads as it did at twenty-five. None of those exists in any form. A clinician who recognises the expectation and says so is being honest; one who accepts payment and proceeds anyway is selling a course rather than a result.

A concern that is really about something else

Fine lines are sometimes the words used for something harder to name: a face that has lost volume, a jawline that has softened, skin that has changed since an illness, or a general sense that something is different and cannot be described. Those are different problems with different answers, and a surface treatment will not address any of them.

What doing nothing actually means

It does not mean neglecting the skin. Gentle cleansing, moisturising and daily sun protection are worth doing on their own account and cost very little. What doing nothing means is declining the in-clinic rungs, which is a legitimate choice.

When the answer changes

The answer changes if a change appeared suddenly, if it is one-sided, if the skin has become red or scaly or sore, or if the concern has become specific enough to describe in one sentence. Until one of those happens, watching is a plan.

Do not watch these

  • A fold or droop that appeared over hours or days, especially on one side.
  • Numbness, tingling or altered sensation in the face.
  • A patch that is red, scaly, sore, changing or failing to heal.

What a consultation should establish before any decision is made is set out in Questions to Ask Before Treating Fine Lines. The findings that route a change to a doctor are listed in When Lines Are Not an Ageing Change.

Frequently asked questions

Is it wrong to want treatment for lines that are normal for my age?

Not at all, and this site is not arguing against treating anything. It is arguing that the decision should be made knowingly: lines that are normal for your age will not be removed, the treatment addresses one contributor at most, and the result is maintained rather than fixed. A person who knows that and still wants it is making a reasonable choice.

Do lines that only appear when I smile need anything doing?

No. A line that exists only in movement is a normal feature of a face that moves, and there is no medical reason to treat it. The only available treatment addresses the muscle, it lasts for a period, and it needs repeating indefinitely. Whether that is worth it is a preference rather than a health question.

What if I want a result that nothing on the ladder produces?

That is the most common reason a treatment disappoints, and it is worth saying out loud at an assessment. A face without lines, a result that lasts without maintenance, or skin that reads as it did twenty years ago are not available. A clinician who recognises the expectation and says so is doing you a favour; one who accepts it and proceeds is not.

Risks & Limitations

  • None of these treatments stops the underlying ageing. Lines are softened and that softening is maintained, and they return as the tissue continues to age.
  • Relaxing a muscle addresses movement only and does nothing for a line set in the skin at rest. Resurfacing addresses the skin and nothing for the muscle that folds it. Volume addresses lost support and nothing for either.
  • Resurfacing and energy-based sessions carry downtime and a risk of pigment change that is greater in deeper skin tones. Injectables carry risks that depend on the area treated and on the person placing them.
  • Sun protection is the only step with a long-term effect on how lines progress, and it reduces further damage rather than reversing what has already happened.

When to Seek Care

  • A fold or droop that appeared suddenly, or on one side only, especially with weakness or difficulty speaking — emergency care.
  • Numbness, tingling or altered sensation in the face — seek medical assessment before any cosmetic plan.
  • A patch that is red, scaly, sore, changing or failing to heal — have it diagnosed rather than treated.
  • Widespread wrinkling that developed over months, or with weight loss, fatigue or a new medicine — seek medical assessment.
