Filler, anti-wrinkle injections, skin boosters or a device: which does what

Which does what: the six injection families and the devices

• Anti-wrinkle injections: a prescription medicine that temporarily blocks the signal from nerve to muscle, so the muscle relaxes and the line it kept folding softens. It affects only movement, wears off on its own (usually three to four months), and does nothing for lost volume.
• Dermal filler: a hyaluronic-acid gel placed beneath the skin to add volume and structure, for cheeks, chin, jaw, lips and folds. The change shows straight away and fades over six to eighteen months; it can be dissolved if needed.
• Skin boosters: un-crosslinked hyaluronic acid with nutrients, as many tiny injections, to hydrate; usually two or three sessions, then a refresh about every six months.
• Biostimulators: biodegradable particles that prompt your own collagen; firmness rather than filling, building over two to three months and typically lasting around two years.
• Polynucleotides and PRP: regenerative injections that signal your cells to repair; they do not fill, lift or relax.
• Devices: focused ultrasound, radiofrequency, RF microneedling and lasers act with heat or light, with no product injected.

Is anti-wrinkle injection a filler?

No. They are different medicines doing different things. Anti-wrinkle injections relax a muscle so a line softens; they do not add volume. Filler adds volume and does not relax a muscle. People often confuse the two because both are injections for the face, and many plans use both: one for the lines that move, the other for the hollow or the fold.

Is a skin booster a filler?

No, although both are hyaluronic acid. Filler is cross-linked into a firm gel that fills space; a skin booster is not cross-linked, so it stays fluid, spreads through the skin and hydrates it. A booster is for the quality of the skin, not for volume, movement or lift. If what bothers you is a deep fold or a softer jawline, a booster will not answer it.

Biostimulator or filler?

Filler fills space and the change is immediate. A biostimulator gives your own collagen a prompt over weeks, so the change is gradual and reads as firmness, not filling. Hyaluronic-acid filler can be dissolved if needed; biostimulators cannot, so the type, dilution and depth are the doctor's call, and the amounts start modest.

Injections or a machine?

It depends on what has changed. For lines from movement: anti-wrinkle injections. For lost volume: filler or a biostimulator. For dry, dull skin: a booster. For looseness: a device, focused ultrasound for a softened jawline or neck and radiofrequency for earlier softening. Texture, scars and pigment: radiofrequency microneedling, a laser or light. A device and an injection are also planned apart in time, so a recent injection simply means spacing.

How to choose

• Name what bothers you in your own words: lines when you move, a hollow, dull skin, a softer jawline, scars, spots.
• Ask the doctor which problem it is, not which product to buy.
• Expect a plan that starts modestly, with a review before any top-up.
• Expect to hear "nothing yet" or "a different treatment" when that is the honest answer.

Who should wait

All of these wait during pregnancy and breastfeeding. The doctor checks for allergies, infection or inflamed skin in the area, bleeding disorders and blood thinners, and what you have had before; never stop a prescribed medicine on your own.
