Dermal filler.

Subtle, and only where it truly helps. Filler is about restoring the structure you have lost, so you look like a rested version of yourself. Balance, never volume.

Who it helps.

  • Lips that have thinned or flattened, or an asymmetry you want evened
  • A jawline or chin that reads weak or recessed in profile
  • Cheeks and mid-face where support has been lost
  • Smile lines you want softened, not erased
  • Fine lines around the mouth, with the lightest filler we use
Not right now if

Who should wait.

  • Significant skin laxity, which filler cannot lift and can look unnatural if we try
  • Pregnant or breastfeeding
  • An active cold sore, infection or dental work in the last two weeks
  • Under 18, without exception
  • We check all of this at your consultation
How it works

Structure, not volume.

Hyaluronic acid filler replaces the support we lose with age, the bone, fat and collagen that quietly recede, placed precisely to lift and balance rather than inflate. Every area has a reason. In the mid-face it restores the support the cheek has lost. Along the jaw and chin, small volumes along the bone can rebalance a whole profile. In the lips, a softer gel restores lost hydration and definition without changing how your mouth moves.

Filler cannot fix skin quality, texture or fine lines, and adding more to try is a common cause of the overdone look. It is a medical device, and who can legally inject it in England is still loosely regulated, so choosing a medically trained practitioner is the entire point.

The serious risk is filler entering a blood vessel. It is rare but real, so we favour a blunt cannula over a needle in higher-risk areas, inject slowly in small amounts, and always have the reversal agent on hand. Hyaluronic acid filler is one of the few things we use that can be dissolved quickly if we ever need to.

How Dermal filler works, illustrated
On the day

What a visit looks like.

Before

Consultation and consent

A medical professional assesses you, maps your face and shows you the plan before anything starts. Photos for your file.

Treatment

Numbed, 20 to 30 minutes

Numbing cream first. Cannula where it is safer, needle where it is more precise. Comfortable for most people.

After

See it the same day

Some swelling, now and then a small bruise. Lips swell more than anywhere else, so do not judge the result that evening.

Review

Two weeks

The true, settled shape shows at around two weeks, which is when we assess for any touch-up.

Pricing

Clear prices, nothing hidden.

Priced per area and per volume. We build conservatively and would rather under-treat on the day and review than overcorrect.

Our honest take

Nothing ages a face like too much filler.

We do less, we balance, and we would always rather lose the treatment than have you look overdone. If you have been overdone elsewhere, we can dissolve it and start again, honestly. And none of it holds a candle to what your skin does when you look after it with medical-grade skincare underneath.

Questions we are asked most.

Will my lips look done?

Not here. The best lip filler is the kind people notice looks good, not that you have had it done. We build gradually over a couple of sessions rather than overfill in one go.

How long does it last?

Six to twelve months in the lips, because they move so much, twelve to eighteen along the jaw and chin, nine to eighteen elsewhere.

Is it safe?

The serious risk is rare but real, and it is why technique and training matter. We use a cannula where it is safer, go slowly, and always have the reversal agent on hand.

I get cold sores. Does that matter?

Yes, tell us at consultation. The injection can occasionally trigger one, and we can talk about antiviral cover beforehand.

Often part of the same plan.
