Skin boosters are often sold as one category. They are not. This neutral guide from IN Eternity Clinic on Orchard Road explains how Skinvive, Profhilo and other boosters differ, and how Dr Sin Yong decides between them.
WhatsApp to Enquire →Key facts ↓Skinvive is a lightly cross-linked hyaluronic acid with lidocaine, injected as tiny droplets to smooth and hydrate cheek skin. Profhilo is a non-cross-linked hybrid hyaluronic acid that spreads through the skin from a few points. Polynucleotide boosters target repair, and PDLLA boosters stimulate collagen. The right choice depends on what your skin lacks.
The term skin booster is a marketing label rather than a medical category. It is used for injectables placed in or just under the skin to improve how the skin looks and behaves, rather than to change facial shape. Under that label sit products with very different chemistry: hyaluronic acid gels, polynucleotides from DNA, and polymers that stimulate collagen.
This matters because people often compare boosters by brand and price, when the more useful comparison is mechanism. A product that holds water in the skin does a different job from one that prompts repair, and both differ from one that triggers new collagen. Choosing well starts with knowing what your skin is short of: water, resilience, or structure in the dermis.
It also helps to place boosters among the other tools. Fillers restore volume and shape. Collagen stimulators placed deeper support structure over months. Energy-based treatments such as lasers, radiofrequency and focused ultrasound work on tone, texture and tightening. Boosters sit in between: they act on the quality of the skin itself. Many good plans use more than one of these, in a deliberate order, rather than relying on a single product to do everything.
This guide is neutral. It explains what these products are and how they are used. At IN Eternity Clinic, Dr Sin Yong will tell you at assessment which option he recommends and why, including when the answer is none of them.
Skinvive is a hyaluronic acid injectable from the Juvéderm range, known in some markets as Volite and in studies as VYC-12. It contains hyaluronic acid at a relatively low concentration, with lidocaine for comfort, and the hyaluronic acid is lightly cross-linked. Light cross-linking slows the body’s breakdown of the gel compared with plain hyaluronic acid, without making it firm enough to add shape.
It is injected as a series of tiny droplets into the dermis across the cheeks. Prospective studies have reported improvements in measured skin smoothness and in how satisfied people were with their skin over several months, with mostly mild, short-lived injection-site reactions. It has been studied mainly on the cheeks; other areas are used with less published evidence.
Because it is hyaluronic acid, Skinvive can be broken down with hyaluronidase if needed. The trade-off of the microdroplet technique is a larger number of injections and visible small bumps on the day, which usually settle within a day or two.
Because of its placement and design, it tends to be discussed for people whose cheek skin looks rough, slightly crepey or dehydrated, who want smoother texture without any change in contour. It is less relevant where the main problem is pigment, redness or laxity, and it does not replace sun protection or a sound skincare routine, which remain the base of any skin-quality plan.
“I choose a booster by what the skin lacks, not by what is trending. Sometimes the honest answer is a laser, or nothing at all.”
Profhilo, from IBSA, contains a high total concentration of hyaluronic acid in two sizes: long chains and short chains. Instead of chemical cross-linking, the two are bound into stable hybrid complexes by a heat process. The result is a fluid gel that spreads through the tissue after injection rather than staying where it is placed.
That spreading behaviour is why Profhilo is given from a small number of points per side of the face, often called the BAP technique, usually as two sessions about a month apart. Studies report improvements in skin hydration, laxity and appearance over several months. It is used on the face and neck and, with suitable technique, on other areas such as the hands. Profhilo at IN Eternity Clinic explains the clinic’s approach.
A related product, Profhilo Structura, is formulated for the deeper fat layer of the lateral face and is a different treatment with a different aim.
Profhilo is often chosen by people who want an overall improvement in hydration and firmness across the face or neck with relatively few injection points. Because it spreads, it is less suited to targeting a single small area precisely. Swelling at the injection points is visible on the day and usually settles within a day or so.
Polynucleotides. Products such as Rejuran and Plinest are purified DNA fragments from fish. They are used for thin, sensitised or slow-healing skin, fine crepiness and the under-eye area, and consensus reports describe their use for skin quality and repair. They tend to sting more and leave visible bumps for a day.
PDLLA boosters. Juvelook combines poly-D,L-lactic acid with hyaluronic acid. The polymer prompts new collagen over weeks, so it is considered for texture, pores and shallow scarring. It cannot be fully dissolved, which makes careful dosing important.
Needle-free boosters. Some actives are delivered into the upper skin without injection. The Deep Synergy Booster uses ultrasound delivery with no needles. These suit people who want hydration and glow with minimal marks, though they act more superficially than injected products.
Injected boosters share a similar routine. The skin is cleansed, numbing cream is often applied for half an hour or so, and the product is placed with fine injections or a cannula. Products containing lidocaine, such as Skinvive, become more comfortable as treatment proceeds. Polynucleotides tend to sting more; Profhilo involves fewer injection points but a brief pressure as each bolus is placed.
On the day, expect small raised bumps or blebs at the injection points, which usually flatten within hours to a day, and possible pinpoint bruising for several days. Most people return to work the next day. Strenuous exercise, saunas and facial massage are avoided for a day or two unless advised otherwise.
Early plumpness is partly water and swelling and fades within days. Any lasting change in texture, hydration or firmness develops over the following weeks and, for most products, across a course. That is why review appointments are spaced out, photographs are taken in the same light, and further sessions are decided on what the skin shows, not on a fixed package.
A simplified comparison, for orientation only:
| Booster | Main ingredient | Main aim | Can it be dissolved? |
|---|---|---|---|
| Skinvive | Lightly cross-linked hyaluronic acid with lidocaine | Smoothness and hydration of cheek skin | Yes, with hyaluronidase |
| Profhilo | Non-cross-linked hybrid hyaluronic acid | Hydration and firmness across the face and neck | Yes, with hyaluronidase |
| Polynucleotides | Purified fish DNA fragments | Repair and resilience of thin skin | Not applicable; absorbed naturally |
| PDLLA booster | Poly-D,L-lactic acid with hyaluronic acid | Collagen stimulation for texture | Hyaluronic acid part only |
Longevity is not listed because it varies between people, areas and studies, and short-term hydration is easily mistaken for lasting change.
Dr Sin Yong starts with the skin rather than the product. Dry, dehydrated skin with fine lines often responds to hyaluronic acid. Thin, reactive or slow-healing skin may suit polynucleotides. Rough texture, enlarged pores or shallow scarring may point to a collagen-stimulating option, or to an energy-based treatment instead of an injection. Volume loss and sagging are different problems, and no booster solves them.
Practical factors matter too: how many injection marks you can accept, how much time you have before an event, previous reactions, and allergy history, including fish allergy for polynucleotides. Combining a booster with lasers or other treatments is possible, but the order and spacing are planned so that each can be judged fairly.
Any injectable used in Singapore should be registered with HSA. The HSA registration guide explains how to check a product yourself.
No. Both are hyaluronic acid, but Skinvive is lightly cross-linked, contains lidocaine and is placed as many tiny droplets in the cheeks, while Profhilo is non-cross-linked, highly concentrated and spreads from a few points. They are used for overlapping but different aims, and the injection experience differs too.
Published studies follow each product for several months, but longevity varies with the person, the area and lifestyle, and studies differ in design. It is more useful to plan a course and review than to rely on a fixed number.
Yes. IN Eternity Clinic offers Skinvive, as well as Profhilo and other skin boosters. Dr Sin Yong will explain which boosters he recommends for your skin and why, including how they compare with Skinvive. He will not recommend a product simply because it is requested, and will say so if a different treatment would serve you better.
Often, yes. Boosters and energy-based treatments work on different parts of the problem: one on hydration or repair, the other on tone, texture or tightening. Sequencing matters so that each treatment can heal and be assessed fairly. The order and spacing are set at consultation.
Some are. Polynucleotides are often considered for sensitised, thin skin, while needle-free options can suit people who want minimal marks. Active eczema, rosacea flares or infection are usually settled first, because inflamed skin reacts less predictably. Suitability is decided after examining your skin in person.
Bruising, swelling, small bumps and redness at injection points are common and usually short-lived. Less commonly, lumps, infection or allergic reactions occur, and collagen-stimulating boosters can form nodules. Rarely, any injectable can enter a blood vessel. These risks are discussed for your specific case before treatment.
Fees depend on the product, the amount used, the number of sessions and the area treated. Comparing price per syringe can mislead, because the products do different jobs and need different numbers of sessions. Fees are explained at consultation once the recommended plan is clear.
