Where do acne procedures fit?
Procedures should be considered for a defined concern, with the evidence and limitations explained alongside medical options. A discussion should distinguish treating active acne from addressing the marks or scars left behind.
Chemical peels
A systematic review of 12 randomised trials found that chemical peels may improve acne, although study quality ranged from very low to moderate6. The evidence was insufficient to identify one peel as consistently superior6.
Our chemical peel guide explains this treatment category. Ask which concern the proposed peel addresses and how it fits with your current skincare and medication.
LED light treatment
Studies of blue light treatment have produced mixed findings, with limitations including small samples, short follow up and risk of bias7. A systematic review advised caution when interpreting the available evidence7
The clinic’s LED light treatment guide provides further background. Discuss the expected contribution of light treatment before deciding whether to add it to a medical regimen.
Selective sebaceous gland radiofrequency
Selective sebaceous gland radiofrequency has been studied for inflammatory acne8. In a randomised study with 63 participants completing treatment, the treated group showed greater improvement in inflammatory lesions at 12 weeks than the control group8.
Our guide to selective sebaceous gland treatment explains the approach. Any recommendation should identify the lesions being targeted and the role of ongoing acne care.
How long does acne treatment take?
Many acne treatments need six to eight weeks before improvement becomes noticeable9. An initial treatment review at around 12 weeks is commonly recommended, although the appropriate timing depends on the treatment and clinical circumstances9.
The review should consider new breakouts, discomfort, irritation and how consistently the regimen has been manageable9. The purpose is to decide whether to continue, simplify or adjust treatment rather than judge progress from a single spot.
Contact the clinic earlier when treatment causes troublesome symptoms or the acne is worsening. Bring details of what has changed, including any products added since the previous appointment.
What happens when acne returns?
Acne can recur after treatment, including after a course of isotretinoin10. A large cohort study published in 2025 documented patients requiring further acne treatment after completing isotretinoin, illustrating that initial improvement and lasting remission are different outcomes10.
Maintenance treatment may help preserve improvement, with topical retinoids recommended for suitable patients after successful acne control3. The plan should explain what to continue, what can be reduced and when reassessment is appropriate3.
A return of breakouts is a reason to review the pattern and previous response. Discuss the timing, severity and any difficulty continuing the earlier routine before deciding on another course or additional procedure.
What skincare supports acne treatment?
Gentle cleansing and a suitable moisturiser can help reduce irritation associated with topical acne medicines3. Avoiding harsh cleansers and unnecessary astringents is also part of improving treatment tolerance3.
Keep a record of the products you use so the routine can be reviewed as a whole. Dr Rachel Ho’s guide to skincare ingredients for acne can help you prepare questions about ingredients already in your bathroom cabinet.
What about back and body acne?
Acne can affect the chest and back as well as the face2. The extent of involvement helps determine whether topical treatment is sufficient or an oral option should be discussed2.
The clinic’s back and body acne guide covers these concerns separately. Mention every affected area during assessment, even when facial breakouts are the main reason for your visit.
Can acne marks and scars be treated alongside active acne?
Flat red or brown marks differ from scars that alter skin texture2. Identifying which changes are present helps separate the goal of reducing new breakouts from treatment of existing colour or structural changes2.
The timing of additional treatment should be discussed alongside the acne plan. Some approaches can address acne and pigmentation together, while structural scar procedures require a separate assessment3.
Our guide to acne marks and acne scars explains the distinction. Readers concerned about indentations can also consult the acne scar treatment guide before discussing suitable options.
What changes during pregnancy or breastfeeding?
Pregnancy plans should be discussed before starting or continuing acne medicines5. Isotretinoin is contraindicated during pregnancy, while spironolactone and topical retinoids should also be avoided during pregnancy5. Azelaic acid and benzoyl peroxide are among the topical options that may be considered after medical review5.
Breastfeeding requires a separate assessment because the recommendations differ from those for pregnancy5. Tell the doctor about current pregnancy, breastfeeding or plans to conceive so that the treatment discussion reflects your circumstances5.
How much does acne treatment cost in Singapore?
The cost of an acne plan depends on what is recommended after assessment. Ask for the consultation fee and clarify the expected costs of medicines, any indicated tests, review appointments and optional procedures before proceeding.
It is useful to distinguish the cost of starting treatment from the cost of ongoing care. Our consultation guide explains questions to ask about estimates, inclusions and follow up. Skin Longevity Clinic
