Understanding Fillers

December 18, 2018
Fillers Singapore Dermatologist

Dermal fillers are minimally invasive mainstay cosmetic treatments used to help return the appearance of volume and youth to ageing skin. Volume deficiency, scars, wrinkles, lip augmentation (plumping), facial sculpting and contouring are common facial concerns targeted by dermal fillers.

This guide will tell you everything you need to know about them: how they work, the choices of products on the market, and their possible side effects on your body and skin.

What are dermal fillers?

Before starting on dermal fillers, we need a brief understanding of how the face changes as we age. Over time, the thickness and elasticity of our skin decreases, and our faces loses fat. Soft tissues sag, facial muscles weaken, and the outermost layer of skin wrinkles.

Enter fillers. Dermal fillers help restore lost volume to your face and add lift.

Types of dermal fillers

The classifications of dermal fillers vary according to their properties. Fillers are categorized based on their biodegradability, how long it takes before the filling substance is absorbed by the body, and the duration of a treatment’s effect.

Early attempts to use fillers for facial rejuvenation relied on dermal fat or collagen fillers. However, the effectiveness of fat as a filling agent was risky as a number of variables were involved. These included the method and type of fat harvested, both of which could cause inconsistent absorption rates by the body. There could also be significant side effects including prolonged swelling, internal bruising and cause infections. Bovine (cattle) collagen, the first collage filler used, also had limited success due to its short duration of effect (3-4 months) and potential risk of allergic reaction.

Human-based collagen has since been developed but demand for collagen remains low compared to more effective filling agents.

Biodegradable fillers

These are fillers that provide temporary or semi-permanent effects as they gradually degrade and get absorbed by the body. Common biodegradable fillers are collagen, hyaluronic acid, calcium hydroxyapatite and poly-L-lactic acid.

Hyaluronic acid

Naturally present in our skin and connective tissues, hyaluronic acid is a key structural component that stabilizes cellular structures and binds collagen and elastic fibers. Hyaluronic acid remains as the most widely used dermal filler due to its ease of use, safety and minimal side effects.

When hyaluronic acid is injected into the skin, it combines with the natural hyaluronic acid found in our body. Due to its hygroscopic nature (ability to absorb water from surroundings), hyaluronic acid binds to water quickly, creating volume that lasts for 6 to 12 months before degrading into the body. It also induces new collagen formation, a desirable quality as our bodies gradually stop producing collagen in our late twenties.

Poly-L-lactic acid (PLLA)

A synthetic, biodegradable polymer of the alpha-hydroxyl-acid family (natural acids found in food), poly-L-lactic acid (PLLA) is another common filling agent. Its safe profile enables PLLA to be actively used in other medical applications such as in dissolvable stiches or soft tissue implants.

PLLA triggers mild inflammation to promote the formation of collagen and tissue fibers. The accumulation of collagen creates volume at the site of injection. Over time, PLLA breaks down into lactic acid and is metabolized to carbon dioxide or incorporated into glucose molecules.

Calcium hydroxylapatite (CaHA)

CaHA is a synthetic compound with a chemical structure that resembles a component found in our bones and teeth. Treatment with CaHA is safe and will not cause allergic reactions. When injected into skin tissues, our body gradually absorbs CaHA, inducing new collagen to be produced. Such an effect typically lasts about 15 months or longer.

CaHA breaks down into calcium and phosphate ions before finally being excreted by the body.

Nonbiodegradable fillers


Injecting silicone into the face adds volume directly and immediately and also triggers collagen production that adds to the effect. Silicone is favoured for its stable chemical structure, ease of use, low cost, and long-lasting effects. As a non-biodegradable filler, silicone stays in your body once it is injected.

However, the use of silicon in cosmetic treatments is controversial due to its potential to cause long-term complications such as abnormal swelling, blindness or nerve damage. Issues can also arise from poor injection technique, the amount of silicone used and differences in silicone grades. For these reasons, it is strongly recommended you get your fillers done only by a trained dermatologist.

Warnings and alternatives

Administered professionally and with the proper technique and expertise, a dermal filler comes with minimal side effects. However, with many different rejuvenation treatments available, it’s important you consult a trusted dermatologist for a professional assessment before commencing treatment.

For those who prefer plumping effects without an injection, go for Dr TWL’s Hyaluronic Acid serum. As a skincare ingredient, hyaluronic acid draws moisture from its surroundings and keeps the skin well-hydrated; it is able to hold over 1,000 times its own weight in water. This gives a desirable plumping effect and improves fine lines and wrinkles without the needles.

Why Your Dermatologist Would Recommend Soft tissue fillers

October 3, 2017
Soft Tissue Fillers by Singapore Dermatologist

What are soft tissue fillers?

Soft tissue fillers are injectables that aim to reduce wrinkles, hollows, and furrows or “plump up” or the skin to give the skin a smoother and more pleasing appearance. Derived from either natural or synthetic substance, these fillers are effective at contouring specific areas of the face, such as around the lips and mouth, and correcting depressions and scars.

Who are soft tissue fillers for?

Each filler product is designed for different purposes and effects. For those looking to correct wrinkles, enhance their lips through volume augmentation, correct thin, superficial lines around the eyes, mouth and forehead area, looking to contour the areas around their chin and cheeks area and correct deep folds, soft tissue fillers are an effective treatment method.

What should I know about soft tissue fillers?

Soft tissue fillers come in two forms — natural and synthetic. Synthetic fillers are often a popular choice as they produce immediate results and have a lasting effect in comparison to natural fillers. This is because synthetic fillers are derived from animal and non-animal stabilised hyaluronic acid complex. The sugar chains in these complex are often stabilised for a longer period of time, resulting a lasting effect on the skin when treated with soft tissue fillers. As soft tissue filler are able to create volume for wrinkle, facial folds, lips and lines treatments, you are able to see immediate results.

What are the side effects of soft tissue fillers?

With recent technological breakthroughs, new synthetic and natural filler substances have been created to reduce side effects such as allergic reactions, redness and occasional bruising, swelling, itching, minor lumps, or tenderness which usually resolves quickly. However that being said, one should be wary of the mentioned side effects and consult a dermatologist immediately.

What to expect from the treatment?

The duration of the treatment usually lasts nothing more than 30 minutes. Prior to the procedure, nerve blocks and local anesthetic creams could be used to minimize discomfort occurring during the procedure. An accredited and trained dermatologist will examine your face and then determine an exact location to inject the fillers to achieve optimal results.

Depending on the areas that are being treated, the depth of the lines, the condition of the skin and the lifestyle of the individual, soft tissue fillers can last up to approximately one year. For optimal results, patients may get their fillers topped up every six to nine months, or an alternative combination regime involving lasers can be discussed with your dermatologist for maintenance. Cosmeceuticals may also be used as adjuncts to maximise the benefits from filler procedures. Hyaluronic Acid for example, apart from being a constituent of fillers, can also be used in a topical form to enhance hydration and plumping effects on skin.

Dermal Fillers? The Fountain of Youth Recommended by Dermatologists

September 27, 2017
Dermatologist Dermal Fillers

Known for her overtly luscious pout, Kylie Jenner has created a buzz around dermal fillers. For those who are looking to enhance their appearance without wanting to go under the knife or suffer the healing downtime drinking pumpkin soups, dermal fillers are an excellent semi-permanent and in some cases permanent option.

Propitious to give you more natural finish compared to botox, dermal fillers are gaining popularity amongst those seeking for youthful perfection. Instead of stopping the muscle movements resulting in wrinkles, dermal fillers aim to plump the skin to smooth out the wrinkles. This does not mean that botox does not have its benefits — read about it here. As both botox and dermal fillers function differently, a combination treatment allows you to walk out of your dermatologist’s office looking 10 years younger.

Types of Dermal Fillers

Setting out to give you a younger face, plumper lips and higher and even nose bridges, dermal fillers come in two different forms – synthetic and natural. Although naturally-derived fillers have a much smaller risk of causing an allergic reaction and risks of migration and lumping and are able to produce an immediate effect, they usually only last from three to 18 months

To maintain your desired result, you will need to go back in and get more fillers injected usually within a year. Synthetic fillers on the other hand, are more of a semi-permanent solution. However, since synthetic fillers provide a more permanent solution, potential allergies and risks of migration and lumping gets harder to correct. To avoid such risks, it is advised that you share your concerns and have a discussion with accredited dermatologist. For an instant youth rejuvenation, fillers are the way to go ladies.
