A skin booster is a series of micro-injections into the dermis directed at skin quality rather than shape: hyaluronic acid hydrates, polynucleotides support repair and PDLLA builds firmness gradually. For a skin booster in Singapore, Dr Sin Yong matches the class to what the skin lacks, and plans hollows or sagging separately.

A skin booster is not a filler. It adds no volume and does not change facial shape — it is injected to act on the quality of the skin itself. Several distinct classes exist, and they are not interchangeable.
Skinboosters in Singapore cover several different product families, and this page sets them out side by side. Hyaluronic acid boosters hydrate, Profhilo remodels laxity, polynucleotides repair thin or damaged skin, and exosomes are applied after laser. Dr Sin Yong examines the skin and chooses by what it needs rather than by brand.
Dull and dehydrated, crepey and loose, or thin and damaged each point to a different booster.
Intradermal micro-injections or the BAP five-point technique, after numbing.
Boosters pair with laser or RF microneedling when texture or scars need more.
Suitability is decided at an in-person assessment. No prices are quoted on this page; fees are given in writing after the assessment. Images and video are illustrative, not patients.

Skin booster treatment in Singapore uses injectables placed into the skin to change its quality rather than its shape, adding no volume. Several classes exist, including hyaluronic acid boosters and Profhilo®, and they are not interchangeable, so Dr Sin Yong chooses between them after assessment.
Also called: skinbooster injections, 水光针, 水光注射
“A skin booster treats the quality of the skin. A filler occupies space. Confusing the two is the most common error patients arrive with.”
Dr Sin YongOn the distinction
A skin booster suits dull, dehydrated skin, fine surface lines, crepey texture and early loss of firmness, and Dr Sin Yong chooses the class by what the skin lacks. The term covers a group of injectables that share one property: they are placed into the skin to change its quality rather than its shape. Fine lines, laxity, dullness and surface texture are the territory. Volume and contour are not, so a hollow is assessed for filler instead.
That distinction matters more than the brand names. A patient who wants a hollow cheek corrected needs a filler. A patient whose skin has thinned and lost elasticity needs something else entirely, and giving them filler produces a face that is fuller but no better in quality.
A skin booster in Singapore is chosen by what the skin is short of, not by brand. Dryness, early loss of firmness, thin skin and texture each point to a different class. Some concerns need a second treatment, because a booster changes skin quality and adds no volume. The table matches common concerns to the class usually weighed first.

| Concern | Class usually weighed | Tends to suit | Not for |
|---|---|---|---|
| Dry, dull, dehydrated skin | Hyaluronic acid skin booster | Skin with fine surface lines that looks tired | A hollow or lost volume, which needs filler |
| Early loss of firmness, crepey skin | Profhilo bio-remodelling | Skin that has started to soften but has not descended | Descended tissue, which needs lifting |
| Thin, fragile skin and fine texture | Polynucleotides, such as Rejuran | Skin where repair, not volume, is wanted | A fish allergy, as polynucleotides are purified from salmon DNA |
| Gradual firmness and texture change | PDLLA biostimulator, such as Juvelook | People prepared for gradual change | Anyone wanting an immediate change |
| Skin quality around acne scars | A booster for the skin around the scars | Scars already treated, where surface quality is the next step | Tethered scars, which need subcision first |
Dr Sin Yong examines the skin himself, with ultrasound where earlier filler is involved, and chooses the class after that assessment. He performs every injection personally. For Profhilo he uses a modified BAP: the defined points serve as the safety framework, and product is then placed where the individual face shape demands it, including into scarred skin.
On the day, numbing cream is usually applied first, and some products contain a local anaesthetic. Product is spread through fine needles or a cannula, in a pattern set by the product and the area. In some areas a cannula reduces the number of entry points. Small raised points, redness and occasional bruising follow, and settle on their own.
Treatment is planned individually, so the cost follows the plan rather than a fixed list. Four things shape it:
A figure quoted before assessment would not reflect your presentation. Cost is set out clearly at consultation, before anything is agreed.
A written quote is given at consultation after assessment. How quotes work at this practice: how we quote.
Skin boosters place small amounts of product in the skin, but they are still injections and carry risks that are explained beforehand. Expected effects are small raised points, redness, swelling, tenderness and bruising, which settle on their own. What to do and avoid in the days after is set out in skin booster aftercare.
Less common are lumps or nodules, where product sits unevenly or too close to the surface. Hyaluronic acid that lies too close to the surface can also give a bluish tint. A flare of cold sores and infection are less common too. Delayed inflammatory reactions are rare; they appear weeks later as tender swelling. Allergic reactions are also rare. That is why component allergies, including fish allergy for polynucleotides, are asked about directly. Any injectable carries a small risk of product entering a blood vessel. With fine superficial placement it is uncommon. But pain that is getting worse, or skin that turns pale (blanching) or dusky after treatment, needs urgent assessment now. That means the doctor who injected you, or A&E.
These risks are reduced by choosing the class for the skin, sterile technique, placement at the right depth for each product, and treatment by a doctor who can manage a complication. What is normal afterwards and what is not is set out on skin booster side effects.
It is the wrong tool for anyone whose main concern is a hollow, descended tissue or pigment, because a skin booster addresses none of those. Which booster suits which goal, and who should wait, is covered in skin booster suitability.
Questions worth asking before any injectable are listed on the questions to ask your aesthetic doctor page.

Read the exosome treatment guide: what topical exosomes are used for after a procedure, and what the evidence does not support.
| How many sessions | A course of 2–3 sessions, 4 weeks apart, then maintenance every 4–6 months. |
| Downtime | Small bumps for 24–48 hours; bruising for a few days in some people. |
| How long it lasts | 4–6 months per course depending on the product. |
Figures are typical ranges from Dr Sin Yong's practice and the published literature; your plan, including the number of sessions, is set after the assessment and may differ. Fees are given in writing after the assessment: see how we quote.
水光针 is the popular term for hydrating micro-injections, usually of hyaluronic acid placed in many small points across the face. It is one type of skin booster, but the term is used loosely; polynucleotides, Profhilo® and PDLLA are different classes doing different jobs.
It depends on the class. Hyaluronic acid boosters are broken down gradually by the body, so their hydrating effect fades unless it is maintained. Collagen-directed classes such as PDLLA and polynucleotides work through your own tissue response, which develops slowly and varies between people. Age, sun exposure, smoking and the condition of the skin all affect how long a change holds. Rather than a fixed duration being promised, the plan is reviewed after the initial phase and maintenance is timed by how your skin is holding.
Most people describe a series of small pricks with some stinging as the product goes in, and the sensation varies with the area, the product and individual sensitivity. Numbing cream is usually applied beforehand, some products contain a local anaesthetic, and in some areas a cannula reduces the number of entry points. The skin around the mouth and under the eyes tends to feel more sensitive than the cheeks. Comfort is checked during the session, and it is fine to ask for a pause.
Mesotherapy describes a technique: many small, superficial injections of a solution into the skin. A skin booster describes a purpose: improving skin quality rather than shape. Some boosters are delivered by a mesotherapy technique, others by fewer deeper injection points or a cannula, so the two terms overlap without meaning the same thing.
No. Treatment for appearance is not claimable under MediSave or MediShield Life, and most private insurance plans exclude it. If you have a question about your own policy, check with your insurer before booking.
Yes, some can. The neck and the backs of the hands have thin skin that shows dryness and crepiness, and certain hyaluronic acid and polynucleotide boosters are used there. The skin is thinner than on the face, so the product, depth and amount are chosen for the area at examination.

“A moisturiser sits on your skin. This is a different conversation, at a different depth.”Dr Sin Yong
Skin Boosters vs Moisturiser
Watch on YouTube: Skin Booster Singapore: Skin Boosters vs Moisturisers
Skin boosters versus moisturisers. A moisturiser sits on your skin. This is a different conversation at a different depth. Topicals work at the surface, exactly where they're meant to. Treatments that place hydrating or stimulating agents into the dermis are addressing a different layer entirely. Neither replaces the other. If anyone tells you one makes the other unnecessary, ask more questions.
