Skin Boosters or Dermal Fillers? How We Decide Which You Need
Patients often arrive asking for one and needing the other.
Skin boosters and dermal fillers are both injectable, both usually hyaluronic acid based, and both routinely described as "anti-ageing". They do different jobs. Choosing correctly matters more than choosing the more expensive option.
What skin boosters do
Skin boosters are designed to improve the quality of skin, not its shape.
They are light, fluid preparations placed into the skin itself rather than beneath it. They do not hold a shape or create volume. They hydrate the tissue and appear to support collagen activity, and the change develops over weeks rather than appearing immediately.
They suit dry or dull skin, crepey texture, and fine lines that are a function of skin quality rather than lost structure. Results typically last 9 to 12 months, and longer with maintenance.
If your concern is that your skin looks tired, boosters are usually the conversation.
What dermal fillers do
Fillers restore volume and structure.
They are firmer gels, placed deeper, formulated to hold their shape and stay where they are put. They replace volume that has been lost, support tissue that has descended, and define features where definition has softened.
The change is immediate. The visible effect typically lasts 12 to 18 months depending on the area — though, as covered in our article on how long dermal fillers actually last, imaging shows the product itself often persists considerably longer than the effect.
If your concern is that your face looks hollow or flat, filler is usually the conversation.
The distinction that actually matters
Skin boosters treat skin. Fillers treat shape.
A booster will not lift a flattened cheek. A filler will not fix dull, dehydrated skin — and using one to try is how faces end up overfilled while still looking tired.
This is the most common thing we correct: patients who have had progressively more filler chasing a result filler was never going to deliver, because the underlying problem was skin quality.
How we decide
Every treatment starts with a face-to-face consultation and a full medical history. We assess skin condition, where volume has genuinely been lost, and what you are actually hoping for — which is not always what you first ask for.
A patient in her forties concerned about tired-looking skin and fine lines around the eyes is usually a booster patient. A patient troubled by flattened cheeks or deepening folds is usually a filler patient.
Often the answer is both, in order. Improving skin quality first and adding structure afterwards produces a better result than either alone — and it usually means less filler, not more.
We will also tell you when the answer is neither.
How treatment is planned
Skin boosters are normally given as a short course of sessions a few weeks apart, building gradually. Fillers are introduced conservatively, with a review a couple of weeks later.
We would rather place less and see you again than place too much in one appointment. Hyaluronic acid filler can be dissolved if you change your mind — using an enzyme called hyaluronidase, which is a treatment in its own right and one we would discuss with you properly first — but not needing to is better.
Book a consultation
If you are unsure which of these you need, that is exactly what a consultation is for. We will assess your skin, explain what we think and why, and tell you honestly if we think you need less than you came in for.
