INFINI ance scars treatment in Singapore


Restore and rebuild collagen to transform your acne scars

INFINI is FDA-approved to stimulate collagen and elastin to improve acne scars, pores, skin laxity and rejuvenation.


What is INFINI Acne Scars?

The INFINI acne scars treatment by Lutronic represents an advance in fractional radiofrequency technology. It was US FDA approved in 2013, and is effective at treating a myriad of skin conditions, such as acne scars, skin laxity, enlarged pores, wrinkles and fine lines.

The depth of energy delivery can be adjusted to scar depth from 0.5mm down to 3.5mm. This will be able to penetrate greater depths of the dermic compared to standard fractional ablative laser devices.

The INFINI acne scars treatment is a breakthrough in fractional and radiofrequency technology. When compared to current fractional Laser and radiofrequency devices, it is more precise, versatile and with a much lower downtime.



Every single case of acne scar is unique and everyone is treated individually based on your acne scar morphology, scar type and your treatment goals. With a carefully planned patient-tailored combination approach, this will lead to more significant improvements in your acne scar appearance. Drawing upon the latest acne scar techniques coupled with his wealth of experience, Dr. Ng will help craft a personalised treatment plan for you to help repair your acne scars and restore your skin.

Each treatment places about 50,000+ Micro-Coagulation Zones

How Does INFINI Acne Scars Treatment Work?

By combining microneedling technology with radiofrequency energy delivered in a fractional pattern, INFINI is able to stimulate dermal collagen at precise depths. The delivery system comprises of 49 gold-plated needles to trasmit consistent thermal energy to the dermis. The entire length of the needle is insulated as it delivers RF energy at the tip of the needle. 

Each session delivers about 50,000 micro-coagulation zones at different layers of the dermis of depths from 0.5 to 3.5mm. The natural healing process then initiates collagen remodelling and elastin formation. This results in the improved appearance of your acne scars.

What Are Micro-Coagulation Zones?

From histological analysis, INFINI treatment creates micro-coagulation zones. These are thermal induced areas of controlled injury within the dermis. They can be precisely place by varying the depth of the treatment. The epidermal layer is spared during the INFINI treatment which explains the faster healing times. The micro-coagulation zones will kick start a natural healing process that involves collagen and elastin synthesis and re-organization in the ensuing months after treatment.


Radiofrequency microneedling releases heat energy within the dermis to stimulate collagen, elastin and dermal remodelling. Over time, your skin will transform and acne scars resurface.

INFINI is able to deliver precise energy to your skin without affecting the epidermis. This results in faster healing times, less redness and less risk of post-inflammatory hyperpigmentation when compared to lasers.

Fractional laser such as CO2 are associated with higher risk of post-inflammatory hyperpigmentation in darker skin. With INFINI, the risk of PIH is minimised as epidermal damage is minimal with the use of insulated microneedles.

Compared to more invasive surgical procedures, microneedle radiofrequency is a relatively gentle treatment. It typically requires little downtime and carries fewer risks and side effects.

The combination of microneedling and radiofrequency can help improve skin texture, minimizing the appearance of scars, enlarged pores, and uneven skin tone.

The radiofrequency energy helps to tighten and lift the skin by promoting collagen remodeling. This can be particularly effective in areas prone to sagging, such as the jowls, neck, and nasolabial folds.

The collagen stimulation and remodeling effects of microneedle radiofrequency can lead to long-lasting improvements in skin quality. However, maintenance treatments may be recommended to sustain the results over time.

The depth of the microneedles and the intensity of the radiofrequency energy can be adjusted to cater to individual skin types and concerns, allowing for a personalized treatment approach.

Different thermal effects and depths

How Is INFINI Different From Lasers?

In the treatment of Acne Scarring, the fibrous tissue (scar tissue) often runs deeper within the dermal layer of the skin. Fractional CO2 Lasers have an average depth of 1.8mm, which is insufficient to target deeper scar tissue.

The INFINI acne scars treatment system uses insulated micro needles with an adjustable depth of 0.5 to 3.5mm to reach the deeper layers of the skin. This is important because different areas of the facial skin would have different thickness levels. For example, treating scars around the temples would require a more superficial depth while cheek areas would need deeper treatments.

Fractional laser systems are considered ablative (destructive) as they penetrate the uppermost epidermal layer of the skin. This is associated with prolonged healing times,  increased risk of pigmentation, and longer duration of redness and swelling. Scar tissue is located in the dermal layer of the skin, and the INFINI system delivers energy to this level without compromising the epidermal layer. This translates to a more precise treatment with better healing times.

Atrophic Acne Scars

Atrophic acne scars are the most common scar type associated with scar. It is mainly due to the loss of collagen and elastin secondary to the inflammatory process. The major clinical subtypes are ice pick scars, boxcar scars, superficial or deep rolling scars. While traditional fractional ablative and non-ablative lasers have greatly improved the appearance of acne scars, they are not without their disadvantage. Fractional ablative lasers such as CO2 and Er:YAG are effective for atrophic acne scars, however they may be complicated by prolonged redness, post-inflammatory hyperpigmentation and scarring. On the other hand, non-ablative lasers may only be effective for superficial scars, with no significant benefit for deeper acne scars. 

Compared to ablative and non-ablative lasers, treatment by INFINI microneedling can be controlled by varying the depth.

INFINI Is best for atrophic and rolling acne scars

Can INFINI be used on all types of Acne Scars?

Different acne scars require different treatments.

The INFINI acne scars treatment system is best suited for mixed acne scars, rolling scars and atrophic scars.

For Ice pick scars, in which the depth of scar tissue is deeper, we use methods such as TCA CROSS and punch excision to resurface the skin. In severe mixed acne scarring, we deal with the deeper scars first before we improve the overall skin texture with INFINI.

What Other Conditions Does INFINI Treat?

INFINI fractional microneedling treatment is clinically proven to stimulate collagen and elastin formation. Besides improving the appearance of acne scars, INFINI has shown to benefit in a wide array of skin conditions:

Skin ageing is due to both intrinsic and extrinsic factors; leading to skin wrinkles, pigmentration, skin laxity and rough skin texture. Radiofrequency microneedling stimulates collagen and elastin, resulting in improved skin tightening, reduced roughness, and more uniform pigmentation. Results are more lasting when compared to botulinum toxin injections. When compared to lasers, microneedle radiofrequency showed better improvement to the nasolabial folds, perioral, jawline and neck wrinkles.

Radiofrequency microneedling is believed to destroy sebaceous glands to reduce its activity and stimulate remodeling of follicular epithelium and dermis. Several studies have shown that it reduces acne severity and prevents longer term acne recurrence. When compared to laser, microneedle RF treatments have lesser risk of pigmentation, reduced downtime and pain scores.

Axillary hyperhidrosis is a distressing disorder of excessive perspiration. Radiofrequency microneedling delivers RF to the dermis to destroy eccrine sweat glands and reduce hyperhidrosis. 

Stretch marks are linear dermal scars caused by progressive stretching of the skin’s underlying connective tissue. They first present as red linear patches (striae rubra), then atrophic white patches (striae alba) in later stages, with the latter being more resistant to treatment. Radiofrequency microneedling is safe and effective at treating stretch marks, with lower down time and pain scores.

Rosacea is a chronic inflammatory disease of the sebaceous glands that presents as persistent facial erythema, flushing, and occasionally, papulopustular lesions. Improvements in rosacea from radiofrequency microneedling may be due to a reduction in inflammation, blood vessels and dermal remodelling.

When Do I See Results?

The natural healing process lays down the foundation for collagen and elastin synthesis, remodelling and re-organization. Individuals will see on-going improvement in their acne scars from up to 12 months due to the process of skin remodeling. Individual results do vary, therefore it is vital to keep a healthy lifestyle to optimise healing after your INFINI acne scars treatment.

Goodman and Baron Acne Scar Grading System

What are the other acne scar treatments?

Releases deep tethered scars within the skin. A variety of approaches is used but a blunt cannula method allows minimal tissue trauma and therefore shorter downtime.

Fractional lasers can be safely combined with INFINI to enhance its efficacy.

Injectable filler treatments such as Hyaluronic acid, Profhilo and Rejuran S elevate scars by restoring volume loss and stimulation of wound healing.

Vascular lasers improve redness and inflammation on the skin. It is useful for post-inflammatory erythema, rosacea, active acne and facial veins. 

An alternative to TCA CROSS for deeper ice pick scars is punch excision. A specialised circular blade is used to surgically remove the deep scars and the wound is sutured together. After 5-7 days, the sutures are removed, and the deep scar is converted to a liner scar which can then be lasered to improve its appearance. 

Keloid scars may result from untreated acne. Keloids are commonly found on the jawline, shoulders and chest. When they cause pain, itch or discomfort, injection steroids help to relieve these symptoms and improve the appearance of your keloids.

Frequently Asked Questions About INFINI Acne Scars

For Fractional ablative lasers (e.g. Fractional CO2 lasers), the epidermis is penetrated before entering the dermis. Healing time is prolonged. Moreover, the risk of side effects such as post -inflammatory hyperpigmentation increases with darker skin tone.

INFINI acne scars treatment is ‘colour blind’ and is effective for all skin types because it bypasses the upper layer of the skin. INFINI can safely be used on dark and tanned skin individuals who are not good candidates for laser treatments.

In preparation for your INFINI treatment , your skin will be cleansed and numbing cream applied. To maximise comfort, the INFINI acne scars system has a built in ComfortFlow technology to deliver smoother energy throughout the procedure. The procedure is well tolerated for most individuals. Out of a pain-scale of 10 (0 – no pain, 10 – most pain), most individuals report only a 3 or 4 out of 10.

A study of 31 patients with atrophic acne scars treated with Microneedling Fractional Radiofrequency showed modest improvement in their acne scar appearance. An objective evaluation was carried out using the Goodman and Baron’s acne scar grading systems. Acne scars are graded 1-4, from mild to severe scarring. 85% and 76% of patients with grade 4 and 3 scars showed 2 grade improvement on the Goodman and Baron acne scar grading scale respectively. Improvement was more noticeable on rolling and boxcar atrophic acne scars.

The INFINI acne scars treatment is based on fractional technology. This means that about 15-20% of the skin is treated per treatment session. This translates into faster healing times. However, several sessions are needed to see optimal results.

The number of sessions you need depends on the type and severity of scarring. In general, 3-4 INFINI sessions spaced at least 4 weeks apart give the most optimal results for acne scarring

In Singapore, the average number of public holidays is 10 days annually, and the number of annual leave is about 14 days. Planning any treatment takes into account your recovery and whether it is fitting in with your precious time. With laser resurfacing, you can expect a downtime of 7-14 days of skin redness, swelling and skin peeling in some instances. 

With INFINI acne scars treatment, a faster recovery time of less than 5 days is seen for most individuals, and make up can be applied after 24 hours.

Mild pin point bleeding and mild bruising may occur in individuals with vascular skin. Recovery is faster than fractional lasers because the epidermal layer of the skin is spared during treatment, while precise energy is delivered into the dermal skin layer. 

The approach to any individual with acne scars must be holistic. A proper clinical examination of the skin under indirect lighting and skin distensibility testing will reveal the scar type and depth. We often combine various treatments such as TCA CROSS, Subcision, Fillers, Rejuran S acne scars treatment to give the best possible outcome.

INFINI treatment for acne scars should be performed by a doctor who has expertise in using radiofrequency microneedling devices. Dr Ng has performed more than 3000 fractional microneedling acne scars treatment across all skin types. It’s essential to choose a reputable provider and discuss treatment options and expectations during a consultation.
