A needle-free skin booster for skin quality and hydration. Nothing is injected: the DSB ampoule replaces the ultrasound coupling gel, and the Ultraformer MPT booster handpiece carries it inward while it works.

Deep Synergy Booster is a needle-free skin booster for skin quality and hydration. Instead of an injection, the DSB ampoule replaces the coupling gel during focused ultrasound treatment, and the Ultraformer MPT booster handpiece carries its contents inward. It cannot place product at a chosen dermal depth the way an injection can.

Key takeaways
  • The Deep Synergy Booster is a needle-free step in which an ampoule replaces the coupling gel in a micro-focused ultrasound session.
  • It is considered for skin quality concerns such as dullness, dehydration and surface texture, not volume loss or sagging.
  • Suitability is decided by examination; it cannot place product at a chosen depth the way an injectable can.
  • It adds no volume and does not lift; it is usually one step within a wider plan.
  • Dr Sin Yong, an aesthetic physician, assesses and performs it, and chooses the cartridge depth for each area.

What the Deep Synergy Booster Actually Is

Most treatments that put actives into skin have to break the surface to do it. A needle passes through it. Microneedling perforates it. Both work, and both leave the skin with something to repair.

The Deep Synergy Booster takes a different route. Focused ultrasound treatment normally requires a coupling gel so the energy can pass from the handpiece into the skin — the gel is inert, and it gets wiped off at the end. Here the gel is replaced by the DSB ampoule. The energy still has to travel through something, so it travels through the ampoule, and the ultrasonic movement carries the ampoule’s contents inward at the same time.

That is the whole idea. The delivery step is not an extra stage added to the treatment — it is the coupling medium the treatment already needed. Nothing is wiped off at the end.

Why Needle-Free Changes the Trade-Off

CLASSYS sets out four ways an active can be put into skin, and they are not equivalent. An ampoule applied to the surface alone achieves minimal penetration. A microneedling stamp and a needle both achieve effective penetration, but they do it by making holes — and the manufacturer’s own comparison lists bleeding, bruising and inflammation among what comes with that. The booster handpiece with the ampoule is placed in the effective-penetration group without a puncture being made.

What that means in the room is simple: there is no injection site, because there is no injection. There is no needle track to bruise, because no needle passes through the skin. This is a statement about mechanism, not a promise about how any individual will look or feel afterwards — skin is warmed during treatment, and how each person experiences that varies.

It also sets the honest limit. A needle can place a product at a depth chosen by the person holding it. An ampoule driven by ultrasound cannot. If what your skin needs is structural placement in the dermis, an injectable skin booster is the right answer and this is not a substitute for it.

What the Ultrasound Is Doing

The booster cartridges run at 4 to 7 MHz, which is 40,000 to 70,000 oscillations per second. Two things happen together. The vibration moves the ampoule’s contents from the surface inward through the epidermis, and the focused beam forms thermal coagulation points at a set depth in the dermis — the same mechanism the focused ultrasound platform uses for tightening.

Three booster depths exist, and they are chosen rather than cycled through. The 1.5 mm derma booster is the shallow cartridge and the one most often used for skin quality work; it can be run in MP mode or normal mode, which behave differently. The 3.0 mm cell-up booster and the 4.5 mm line-up booster reach progressively deeper. The shallow cartridges also reach curved and narrow areas — the forehead, the brow, the zygomatic arch — that flat handpieces sit awkwardly against.

Which depth is appropriate, and whether a booster pass belongs in your plan at all, is decided by examination rather than by the treatment having a fixed recipe.

What Is In the Ampoule

DSB 357 is formulated specifically as an Ultraformer coupling ampoule rather than adapted from a general serum, and CLASSYS states it contains no emulsifier, no pigment and no declared allergen. The named actives include:

Declared components

  • PDRN — polydeoxyribonucleotide, described by the manufacturer as acting on fibroblast activity.
  • Glutathione — the component the formulation is built around, and the reason the ampoule is paired with a delivery method at all.
  • Niacinamide — a barrier-active vitamin B3 derivative.
  • Adenosine and Centella asiatica extract.
  • Seven hyaluronic acids, ten multi-peptides and seventeen amino acids.

A note on the ingredient count: CLASSYS’s own materials give two different totals for the number of active ingredients, so no single figure is quoted here. The named components above are the ones the manufacturer identifies individually.

Where It Sits Alongside Everything Else

Three things on this site sound similar and are not. An injectable skin booster is placed into the dermis through a needle or cannula and is chosen when the skin needs something delivered to a specific plane. The Ultraformer MPT lifting protocol uses deeper cartridges directed at the SMAS and is chosen when the complaint is laxity rather than skin quality. The Deep Synergy Booster sits in neither category: it is a surface-to-dermis delivery step, usually added to a plan rather than standing as the whole of one.

It is often the finishing step of an ultrasound session for that reason — the coupling medium has to be there anyway, so the question is only whether it should be inert.

Who It Suits, and Who It Does Not

It is considered for people whose concern is skin quality — dullness, dehydration, surface texture — and who either do not want needles or are not suitable for them. It is also considered where an ultrasound session is already planned and the coupling step can be made to do more than couple.

Illustrative. The booster suits skin that looks dull or dehydrated rather than skin that has lost volume.

It is not the right choice where the presentation is volume loss, structural descent, or a pigmentary condition that needs to be diagnosed before it is treated. Active infection or inflammation at the treatment site, and known sensitivity to any component of the ampoule, are among the things assessed before it is used. Anyone whose main concern is facial sagging is being assessed for a different treatment entirely.

What Determines the Cost

Treatment is planned individually, so the cost follows the plan rather than a fixed list. Four things shape it:

Factors discussed at consultation

  • The area treated. A single zone differs from several, and surface area drives the work involved.
  • What the assessment finds. The same complaint can have different causes, and the cause decides the approach.
  • Whether the booster stands alone or forms part of a wider plan. It is frequently one step within a session rather than the session itself.
  • How the plan is staged. Work spread over time is planned differently from work done in one visit.

A figure quoted before assessment would not reflect your presentation. Cost is set out clearly at consultation, before anything is agreed.

Who it suits, who should wait, who is referred on

Tends to suit

  • Dull or dehydrated skin with uneven surface texture
  • People who prefer to avoid needles or are not suitable for them
  • Patients already planning an ultrasound session who want the coupling step to do more

Better to wait

  • Active infection or inflammation at the treatment site
  • Pregnancy or breastfeeding, as a precaution
  • A pigmentary concern that has not yet been diagnosed

Referred on

  • Volume loss or structural descent → assessed for filler or a lifting treatment instead
  • Marked skin laxity or heavy skin excess → surgical assessment
Who should not have this treatment
  • Active infection, open wound or marked inflammation at the treatment site
  • Known sensitivity to any ampoule component, including glutathione, niacinamide, PDRN or the hyaluronic acids
  • Pregnancy or breastfeeding, as a precaution
  • Undiagnosed pigmented or suspicious skin lesion in the area
  • Recent resurfacing or irritation of the skin in the area

People whose main concern is volume loss, sagging or an unexplained pigmentary change tend to respond poorly, because this is a skin quality step and the wrong tool for those.

What happens, step by step

  1. Consultation and examination of skin quality, concern and any contraindication
  2. Written plan and quote, including cartridge depth and whether it joins an ultrasound session
  3. Treatment day: skin cleansed, ampoule applied as the coupling medium and the handpiece passed over the planned zones
  4. Review and adjustment of the plan, including whether further booster work is advised

Risks, side effects and when to call

Because no needle is used, there is no injection site and no needle track to bruise. The skin is warmed during treatment, and how each person experiences this varies. Temporary redness, a sense of warmth or tenderness can follow. Less commonly, sensitivity or irritation can develop from a component of the ampoule, and the thermal points can cause discomfort or, rarely, skin marking if energy or depth is mismatched to the area. The treatment cannot place product at a set depth, so it is not a substitute for an injectable where that is indicated.

Contact the clinic the same day if
  • Persistent or increasing redness, swelling or heat in the treated area
  • Blistering, crusting or an open area on the skin
  • Itching, rash or hives after treatment
  • Pain that is worsening rather than settling
  • Any change in skin colour that is developing or spreading

Before you book

What determines the fee

The fee depends on the area treated, the booster cartridge depth chosen, the number of zones or passes the plan needs, and whether the booster is a single step or part of a wider ultrasound or skin quality plan. A single zone is planned differently from several. A written quote is given at consultation, after assessment, and the consultation also decides whether this treatment is advised at all or whether an injectable, a lifting treatment or no treatment would suit you better.

How quotes work at this practice: how we quote.

Myths we hear in clinic

“Needle-free means the product reaches the same depth as an injection.”

Ultrasound moves the ampoule inward but cannot place it at a chosen depth, so it is not a substitute for an injectable skin booster.

“A booster pass will lift sagging skin.”

It is a skin quality step; sagging is a laxity concern assessed for a different treatment.

Frequently Asked Questions

The Deep Synergy Booster is a needle-free skin quality treatment. The DSB ampoule replaces the inert gel normally used to couple a focused ultrasound handpiece to the skin, so the ultrasound energy passes through the ampoule and its contents are carried inward as the treatment is performed. Nothing is injected and nothing is wiped off at the end.

Yes. No needle passes through the skin and nothing is injected. The active ingredients are moved from the surface inward by ultrasonic oscillation rather than placed by a needle. That is a difference in mechanism, and it also sets a limit: a needle can place product at a chosen depth and this cannot.

An injectable skin booster is delivered into the dermis through a needle or cannula, which lets the doctor decide exactly where it goes. The Deep Synergy Booster delivers from the surface using ultrasound, so it does not break the skin but also cannot target a specific plane. They answer different questions, and where structural placement is needed an injectable is the appropriate treatment.

CLASSYS identifies PDRN, glutathione, niacinamide, adenosine and Centella asiatica extract among the actives, together with seven hyaluronic acids, ten multi-peptides and seventeen amino acids. The manufacturer states the formulation contains no emulsifier, no pigment and no declared allergen. CLASSYS's own materials give two different totals for the overall ingredient count, so no single figure is quoted.

The skin is warmed while the ultrasound is delivered, and how each person experiences that varies. Because nothing punctures the skin there is no injection site and no needle track. What happens afterwards is discussed individually at consultation rather than described as a fixed expectation.

It frequently is. A focused ultrasound session needs a coupling medium regardless, so where a lifting protocol is already planned the booster step can replace the inert gel. Whether that is appropriate for you is decided at assessment.

No. It is not appropriate where the presentation is volume loss or structural descent, and a pigmentary condition should be diagnosed before it is treated. Active infection or inflammation at the treatment site and known sensitivity to any component of the ampoule are among the things considered at assessment.

The cost follows the plan rather than a fixed list. It depends on the area treated, the cartridge depth, the number of passes, whether the booster stands alone or joins an ultrasound session, and how the work is staged. A written quote is given at consultation after assessment, and the consultation decides whether it is advised at all.

It can be worthwhile for people with dull, dehydrated skin who want a needle-free route, or who already have an ultrasound session planned. It is not the right choice for volume loss, sagging or an undiagnosed pigmentary condition, and it cannot replace an injectable skin booster where structural placement is needed.

No duration is promised. How long any change in skin quality is noticed depends on your skin condition, age, sun exposure, skincare habits, the area treated and whether it is repeated or combined with other treatments. Review timing, and whether further booster work is advised, are set at consultation and adjusted from how your skin responds.

It cannot place product at a chosen depth, add volume, alter facial shape or lift sagging. The skin is warmed during treatment, which some people find uncomfortable, and temporary redness can follow. Sensitivity to an ampoule component is possible. It usually suits a plan as one step rather than as the whole treatment.
