Skin boosters are micro-injections of lightly stabilised or unmodified hyaluronic acid, sometimes combined with amino acids or antioxidants, placed across an area to improve hydration, elasticity and light reflection. They are given as a course and they do not change facial contour.
| Classification | Medical device, injected |
|---|---|
| Purpose | Hydration, elasticity, fine crepiness and dullness |
| Technique | Many small injections spread across the treated area |
| Course | Commonly three sessions, two to four weeks apart |
| Maintenance | Usually every four to six months |
| Areas | Face, under-eye, neck, décolletage, hands |
| Downtime | Small bumps and possible bruising for one to three days |
This category is frequently confused with two others, and the distinction is worth holding clearly because the treatments answer different questions.
In practice, the categories overlap and clinics use the terms loosely. What matters is what the treatment is intended to change: shape, or quality. Ask that question directly.
Less useful for:
Numbing cream is usually applied first, particularly for the under-eye area and the neck. The product is then delivered in many small injections across the area, either with a needle or with a fine cannula.
Immediately afterwards the area shows small raised bumps at each point, which settle over several hours to a day. Bruising is possible, especially under the eyes and on the neck. Most people are presentable the following day, and many the same evening.
The result is a change in skin quality: better hydrated, more even in light, slightly firmer, with fine crepiness reduced. It is not a change in shape and it is not dramatic in a single photograph. People generally notice it in how their skin behaves through the day and in how make-up sits, rather than in a mirror comparison.
The treatment also does not substitute for daily skincare. Injected hydration into skin that receives no sun protection and no topical support will underperform, and the underperformance will be attributed to the treatment rather than to the routine.
The neck, the décolletage and the hands age visibly and are difficult to treat with resurfacing, which heals slowly and carries more risk in these sites. Micro-injected hydration is one of the few approaches that improves them with acceptable downtime.
Aftercare is straightforward: no make-up on the points for the rest of the day, no strenuous exercise, sauna or steam for a day, and no facials or massage over the area for two weeks.
These treatments are almost always sold as courses of three, which is legitimate because a single session does not produce a durable change. The variables are the number of sessions, the areas included, whether the consultation is charged, and whether maintenance is priced separately.
Be cautious about prepaying for a long programme of maintenance sessions stretching a year ahead. Read what treatment costs for the full breakdown.
Most people considering this treatment are considering others as well, and the order matters more than the individual choices. A reasonable sequence starts with the finding that dominates. If the face has lost structure, treating skin quality first will produce a disappointing result because the underlying problem is untouched. If skin quality is the complaint, adding volume will not fix it and may draw attention to it.
Conventional spacing is around two weeks between an injectable skin treatment and botulinum toxin or filler in the same area, and around two weeks either side of resurfacing. The reasoning is partly practical, because swelling from one treatment makes it hard to assess another, and partly diagnostic: if something reacts, you want to know which treatment caused it.
There is also an argument for doing less at once for a reason that has nothing to do with safety. Treatments assessed one at a time can be judged. Three treatments in one appointment produce a single impression, and if you like it you will not know which parts of it to repeat and which to abandon. Over several years that difference compounds into either a considered plan or an expensive habit.
Commonly three, spaced two to four weeks apart, then maintenance every four to six months.
No. Fillers create shape. Skin boosters improve hydration and quality across an area and do not change contour.
Not really. The first few days bring hydration and light reflection; the durable change builds across the course.
Yes, and it is a common area, but this region can retain fluid. Conservative treatment and an experienced practitioner matter here.
Yes, the neck and décolletage are among the most useful areas, because resurfacing there heals slowly and carries more risk.
Small bumps for a few hours to a day, and possible bruising. Most people carry on normally.
Yes. Injected hydration will underperform on skin that gets no daily protection, and the treatment will be blamed for it.
Treatment
Not a filler. A skin quality treatment that happens to be delivered by injection.
