Breaking the cycle of acne vulgaris — from comedones to cysts. Dr Sin Yong's laser and clinical approach to preventing ongoing acne flares.

12 July 2021
Specific Skin Conditions

Stopping acne flares means treating acne vulgaris, a chronic inflammatory disease of the oil-gland units of the skin, at several points: excess oil, blocked follicles, bacteria, inflammation and the marks left behind. This earlier article describes Dr Sin Yong's laser-led approach, the R2 Glow Laser protocol, alongside other measures for hormonal acne, decided at assessment.

Key takeaways
  • Acne is a chronic inflammatory condition of the oil-gland units, involving oil, blocked follicles, bacteria and inflammation.
  • Laser and light can calm inflamed lesions, but they do not change the cause of acne.
  • Dr Sin Yong uses the R2 Glow Laser protocol, with other measures for hormonal acne decided at assessment.
  • Suitability depends on acne type, medicines taken and skin condition, and laser complements rather than replaces topical or oral care.
  • Dr Sin Yong, an aesthetic physician, performs treatment and refers severe or scarring acne on where appropriate.

Stopping Acne Flares Laser Pimple Treatment

Acne Vulgaris is a chronic inflammatory skin disease of the pilosebaceous unit, affecting approximately 85% of adolescents and persisting into adulthood for many patients. It is characterised by comedones, papules, pustules, nodules and cysts — a spectrum of severity from mild to disfiguring.

The cycle of acne involves increased sebaceous gland activity, abnormal follicular differentiation with increased keratinisation, which predisposes to microbial colonisation and increased inflammation. Other contributing factors include hormonal disturbances, family history, comedogenic products and dietary intake.

Breaking the Acne Cycle

Dr Sin Yong's approach targets multiple points in the acne cycle simultaneously: reducing sebum production, clearing blocked follicles, targeting the bacterial biofilm, and reducing post-inflammatory pigmentation. The R2 Glow Laser protocol is directed at active acne as well as skin texture and tone.

For patients with hormonal-driven acne, a combination approach incorporating oral agents with laser treatment is directed at more of the process than either modality alone. The goal is not just clearance of existing lesions, but prevention of new flares — breaking the cycle rather than managing individual breakouts.

Acne scars are a permanent reminder of past inflammation. Treating active acne early and aggressively is always preferable to later scar reconstruction — prevention spares much of the later scar work.

“A laser can settle an inflamed lesion. It cannot change why the lesion formed, so treating flares without treating the cause is a cycle rather than a plan.”

Dr Sin YongOn the difference between settling a flare and stopping them

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

Tends to suit

  • Inflammatory or persistent acne that has not settled with topical care alone
  • People who also want help with texture or post-inflammatory marks
  • Hormonal-pattern acne where laser is combined with medical treatment
  • Those who accept that flares are managed rather than switched off

Better to wait

  • Pregnancy or breastfeeding
  • Recent isotretinoin, until the doctor judges the skin ready
  • Expectations of a one-off fix that treats the cause

Referred on

  • Severe nodulocystic acne needing prescription medicines, referred to a dermatologist
  • Established deep scars, assessed for scar treatment separately
Who should not have this treatment
  • Pregnancy and breastfeeding
  • Recent or current isotretinoin, reviewed individually
  • Active skin infection or cold sore in the treatment area
  • Photosensitising medicines or recent sun exposure
  • Tendency to keloid scarring or poor healing
  • Open wounds or heavily picked lesions

People hoping laser alone will stop acne tend to respond poorly, because laser settles flares but does not change why they form.

What happens, step by step

  1. Consultation and examination, including acne type, medicines and previous treatments
  2. Written plan and quote, covering laser, skincare and any medicines advised
  3. Treatment day: skin preparation and the planned laser protocol
  4. Review and adjustment: the response is assessed and the plan changed as needed

Risks, side effects and when to call

Redness, warmth and mild swelling are expected after laser and usually settle on their own. Some people notice a temporary flare or purging as inflamed skin reacts. Uncommon problems include post-inflammatory pigmentation, which is more of a concern in Asian skin, blistering, infection and scarring. Laser calms inflammation but does not remove the underlying drivers, so new flares can still appear, and treatment works alongside skincare and, where needed, medicines. Settings are chosen conservatively, adjusted at review, and any change in your skin between visits should be reported to the clinic.

Contact the clinic the same day if
  • Blistering, crusting or skin that looks burnt
  • Dark marks appearing after treatment
  • Increasing pain, swelling or warmth
  • Spreading redness, pus or fever suggesting infection
  • A marked flare that is not settling

See what to do if something feels wrong after a treatment.

Aftercare

First 24 hours

  • Expect warmth and redness and keep the skin clean and cool
  • Do not pick or squeeze any lesion

First week

  • Use gentle, fragrance-free cleanser and moisturiser
  • Avoid heat, heavy make-up and exfoliation while the skin is sensitive

Sun

  • Use broad-spectrum sun protection daily and avoid tanning

Skincare

  • Pause retinoids and exfoliating acids until the doctor advises restarting
  • Continue any prescribed medicines unless told otherwise

When to call

  • Blistering, crusting, dark marks or increasing pain
  • Spreading redness, pus, fever or a marked flare that is not settling

Before you book

  • Declare all medicines, especially isotretinoin, antibiotics and hormonal treatments
  • Tell the doctor about pregnancy, breastfeeding or plans to conceive
  • Avoid sun exposure and tanning before the appointment
  • Pause retinoids, acids and other skincare actives if advised
  • Bring a list of products and treatments already tried, and photographs of how your acne has behaved

What determines the fee

The fee for laser acne treatment depends on the area treated, the laser and consumables used, the number of passes or zones planned, any oral or topical medicines prescribed, and whether laser is combined with another treatment. Because acne varies between people, the plan is set after assessment. A written quote is given at consultation, and the consultation also decides whether laser is advised at all, or whether medical treatment should come first.

How quotes work at this practice: how we quote.

Myths we hear in clinic

“Laser alone stops acne for good.”

Laser can calm inflamed lesions but does not change the oil, follicle, bacterial and hormonal drivers behind new flares.

“Acne means the skin is dirty.”

Acne comes from oil production, blocked follicles, bacteria, inflammation and hormones, and over-washing does not address these.

Frequently Asked Questions

How does laser treat active acne?+

Laser and light therapy reduce acne-causing bacteria, calm inflammation and decrease oil gland activity — helping to stop active flares and prevent new breakouts.

Is laser better than topical acne treatment?+

Laser complements topical and oral treatment rather than replacing it. For inflammatory and resistant acne, combining laser with a tailored skincare plan gives strong results.

How many sessions are needed for acne?+

The number and spacing of sessions depend on the acne and are set at consultation; response varies between individuals.

Will laser also help acne scars?+

Some lasers improve both active acne and early scarring. Established scars are addressed separately with resurfacing and Dr Sin Yong's 4D Scar Reconstruction protocol.

How much does laser acne treatment cost in Singapore?+

The fee depends on the area treated, the laser and consumables used, the number of passes or zones, any medicines prescribed and whether laser is combined with another treatment. A written quote is given at consultation after assessment, and the consultation also decides whether laser is advised or medical treatment should come first.

Is laser treatment for acne flares worth it?+

It can be worthwhile for inflammatory or persistent acne, particularly alongside a tailored skincare plan or medicines. It is less suitable for people expecting laser alone to stop acne, or for severe nodulocystic acne, where prescription treatment and dermatology referral are the right starting point.

How long does laser acne treatment last?+

No duration is promised. Acne is driven by oil, hormones, bacteria and inflammation, which laser does not change, so how long calm skin holds depends on the type of acne, skincare, medicines and individual factors. Review timing and any maintenance are set at consultation and adjusted as your skin responds.

What are the disadvantages of laser acne treatment?+

Laser does not address the cause of acne, so flares can return and treatment sits alongside skincare or medicines. Redness and warmth are expected, and uncommon problems include temporary flare, pigmentation, blistering or infection. It is also unsuitable during pregnancy, and soon after isotretinoin treatment it is deferred until the doctor advises.
