Skin booster (hyaluronic acid)

Hyaluronic acid skin booster · Injectable skin hydrator · Skin quality booster

Recovery: 0–1days
Pain: Moderate
Sessions: 1–3 sessions
Type: Non-surgical

Sessions are spaced apart, so on a short trip you may only get one.

What it is

Small amounts of hyaluronic acid (HA) injected into the skin with many closely spaced injections to improve hydration, texture and glow rather than add volume. 'Skin booster' is a broad label: clinics also use it for PN, PLLA and other injectables, so ask which product is used.

Who it’s for

Adults with dry-looking, dull or finely lined skin who want gradual change in skin quality without added volume.

How it’s done

The skin is cleansed and numbed. Many small injections are placed close together with a very fine needle, then the area is cleaned.

What to get in writing

Recovery

Mild redness and swelling usually last a few hours. Small bumps can appear and are usually temporary. Bruising and needle marks are possible.

Risks and side effects

Pain, bruising and needle marks
Bumps or 'beads' (papules), especially when cross-linked HA is placed too superficially
Redness and swelling for a few hours
Rare: granulomas (persistent lumps)
Rare but serious with any HA filler: injection into a blood vessel, which can damage skin or vision

Questions people ask

How is a skin booster different from a filler?

Fillers add volume and shape. Skin boosters use small, shallow injections, usually of lightly cross-linked or non-cross-linked HA, to target hydration and texture.

When will I see results?

An expert panel reported visible effects after the first session, with progressive improvement for up to 12 months when repeated every 4–6 months after an initial course of up to three sessions.

Does it hurt?

Pain, discomfort and bruising are listed side effects because many small injections are used. Ask whether numbing cream is applied.
