In Brief

These aesthetic treatment questions cover booking, fillers, botulinum toxin, lifting, lasers, scars, hair, body and skin boosters. This hub suits anyone preparing for a first consultation. Short answers cannot assess you, so suitability is always decided in person, and results vary.

About This Treatment

How to use this page

The questions below follow the ten topics listed here, in the same order. Read the topic that matches your concern, then follow the links for more detail.

Every answer is general. It cannot take account of your history, your anatomy or your medicines. Some people should avoid a treatment or wait, and every treatment carries risks.

Before you book: aesthetic treatment questions to ask first

These cover first visits, checking a doctor and fees. See the consultation process and how we quote.

Dermal fillers

These cover filler types, dissolving and vascular risk. Filler is not always reversible, so read our warning signs guide as well.

Botulinum toxin

This prescription treatment is often searched for as Botox. See anti-wrinkle injections and jaw slimming. It acts on muscle, not on fat, skin or bone.

Lifting, HIFU and radiofrequency

These explain how the energy types differ. See HIFU and Thermage. Non-surgical lifting does not remove excess skin.

Lasers and pigmentation

These cover pico laser, melasma and darker marks. See pico laser and melasma treatment. Heat can worsen some pigment.

Acne and scars

Control acne first. See acne treatment and 4D Scar Reconstruction. No single laser treats every scar, and no method erases one.

Hair loss

See male and female hair loss. Treatment supports living follicles, and it cannot reopen one that has stopped.

Body contouring

See the 4K Body Lift and fat freezing. These are not weight-loss treatments, and they suit people near a stable weight.

Skin boosters

See skin boosters. Boosters act on skin quality. They do not add volume or lift, and polynucleotides are generally avoided with a fish allergy.

Safety and aftercare

These cover pregnancy, warning signs and sun care. For anything urgent, go straight to complication care.

Frequently Asked Questions

Ask what is causing the concern, what each option cannot do, the risks, who performs it, and what happens if you choose no treatment.
Search the Singapore Medical Council register through the Ministry of Health's Healthcare Professionals Search. Accredited specialists also appear on the Register of Specialists.
Skin disease, such as a changing mole or unexplained rash, needs diagnosis. Volume loss, laxity or texture are usually an aesthetic physician's work.
No. These are clinical procedures for registered practitioners working in a licensed healthcare provider.
Hyaluronic acid filler can, with hyaluronidase. Calcium hydroxylapatite, polycaprolactone and poly-L-lactic acid cannot be dissolved this way, and they resorb over time.
It is filler entering or pressing on an artery and blocking blood flow. Signs include blanched or dusky skin and severe pain. It is an emergency.
Usually not. Filler that has built up may be supporting the face, so correction is staged by region and reassessed.
It varies with product, dose and metabolism. Repeat timing is planned at review, not on a fixed schedule.
It reduces the force of the muscle. It does not address the cause or replace a night guard, so dental review is part of the plan.
Yes. A registered medical practitioner must inject it after a documented consultation. Units are specific to each product.
Focused ultrasound makes discrete heated points at fixed depths. Monopolar radiofrequency heats the dermis more broadly. Both stimulate collagen, in different layers.
No. A thread repositions tissue it can grip but cannot remove skin. Heavy skin excess needs a surgical discussion.
It can. HIFU is not a fat-reduction treatment, but heat over thin areas of a lean face can leave it looking drawn.
Melasma is sensitive to heat, and Fitzpatrick III to V skin readily rebounds. The next step is reassessment, not more energy.
This is usually post-inflammatory hyperpigmentation. If the condition was melasma, heat may also have driven it.
No. The difference is pulse length. Picosecond pulses are shorter, so the effect is more mechanical and less thermal.
Inflammation from active acne creates scars. Treating scars while the disease continues means working on a surface that keeps being damaged.
Run a fingertip across them. Flat marks are usually pigment and fade over months. True scars have a pit or raised area.
A needle or cannula passes under a depressed scar to divide the band anchoring it, leaving the surface intact.
A miniaturised follicle is alive and can respond. A follicle that has stopped producing cannot be reopened, so follicle status is assessed first.
Most often telogen effluvium, triggered by illness, fever, surgery, childbirth, stress, crash dieting or deficiency. It usually settles once the trigger is corrected.
No. It targets localised fat, not overall weight, and suits people near a stable weight.
No. They are established scarring, so treatment improves how they look. Early red marks generally respond more readily than mature white ones.
No. A filler occupies a location to restore volume. A booster spreads through tissue and acts on skin quality.
No. It is uncross-linked hybrid hyaluronic acid that spreads through tissue, and it is grouped with skin boosters.
Treatment is deferred, because fillers have not been studied in these groups. It is also deferred with an infection at the site.
White, dusky or mottled skin, or severe or worsening pain, needs same-day assessment. Any vision change means going to A&E at once.
Yes. UV varies little here and is often very high. Cloud does not stop it, and UVA passes through glass.
Keep the area clean and moisturised, use any prescribed ointment, protect it from the sun, and let scabs fall off on their own.
Elective laser is generally deferred. Please tell the doctor about pregnancy, plans to conceive or breastfeeding.
