Main guideJuvelook Singapore — what it treats, who it suits, sessions, downtime and what decides the cost, by Dr Sin Yong.
Published 31 October 2026 · Reviewed by Dr Sin Yong
Juvelook aftercare starts with the small raised bumps at each injection point, which are expected and flatten as swelling settles. Leave them alone, keep make-up, heat, alcohol and hard exercise away at first, and massage only as shown. Juvelook is PDLLA in hyaluronic acid, and hyaluronidase dissolves the carrier but not the PDLLA, so a lump that grows, hurts or turns red is reported, not squeezed.
Message the clinic the same day if you notice
A bump that is getting larger rather than flattening.
A lump that is hard, tender or painful, whenever it appears.
Redness, heat or swelling that spreads, or fever.
Swelling that keeps increasing rather than settling.
What should you do and avoid after Juvelook, phase by phase?
The table sets out Juvelook aftercare from the injections to the review. Each row lists what is expected, what to do, what to avoid and the signs that mean you should message the clinic.
Phase
What is expected
What to do
What to avoid
Message or call if
Straight after
A small raised bump at each injection point; redness, swelling and tenderness; sometimes a bruise
A cool compress for short periods; sleep with the head slightly raised; paracetamol if you can take it
Make-up over the points; pressing or rubbing outside the massage you were shown; saunas, alcohol and hard exercise
Skin turning white, dusky or mottled; severe or worsening pain; any change in vision
The early phase
Bumps flattening; swelling easing steadily rather than growing; tenderness fading
Massage as instructed, if instructed; make-up over intact skin once the points have closed; sunscreen daily
Facials, facial massage, gua sha, at-home devices or other injectables over the area
Redness and heat over the area; a tender lump; fever
As collagen forms
Gradual change in skin quality; the area feels ordinary
A simple routine; note when you first feel any small lump and send a photograph
Having more product placed in the area elsewhere before review
A lump that is getting larger, hard or painful; a lump that appears much later
What the early phase looks like, and what is uncommon, is set out on Juvelook side effects.
“A bump on the day is where the product was placed. A lump that grows, hurts or turns red weeks later is a different thing, and it is examined, not massaged.”
What is in the skin after Juvelook, and why does it matter for aftercare?
Juvelook is a collagen-stimulating injectable that combines poly-D,L-lactic acid (PDLLA) microspheres with non-cross-linked hyaluronic acid. The hyaluronic acid gives some hydration and a little fullness on the day; the PDLLA stays in the tissue and prompts the skin to lay down its own collagen gradually over months. Aftercare has to respect both. The fullness you see straight after is mostly water and carrier, so it is not a guide to the result, and the particles need to sit evenly where they were placed.

That second point is why lumps are the main thing to watch for. A 2024 literature review of PDLLA in dermatology described granulomas and non-inflammatory nodules as its recognised complications and stressed monitoring and early intervention. Hyaluronidase dissolves Juvelook's hyaluronic acid carrier but not the PDLLA, so a nodule cannot simply be dissolved as a hyaluronic acid filler can. Dr Sin Yong decides first whether the concern is skin quality, volume or laxity, and he prefers energy-based treatment for most of them; where Juvelook is used, this page is what follows. The product itself is explained on Juvelook Singapore.
Should you massage after Juvelook?
Massage after Juvelook follows the instruction given at your visit for the area treated, and nothing beyond it. Poly-L-lactic acid (Sculptra), a related collagen stimulator, is traditionally followed by a set routine of firm massage; Juvelook's smaller, rounder PDLLA particles in a hyaluronic acid carrier are handled differently, and some areas, such as under the eyes, are not massaged at all. If you were not given a massage instruction, do not start one. If you were, keep it gentle, use the same technique on both sides, and stop if it hurts.
What you should not do is squeeze, knead hard or try to flatten a bump that is red, warm or painful. The evidence on collagen stimulator nodules is mostly from case series. A 2024 series of 55 complications after collagen biostimulators described nodules as the commonest form, usually appearing more than a month after treatment, and found hyaluronidase helpful where hyaluronic acid was also present but not otherwise. A 2025 case report described non-inflammatory nodules after PDLLA in the tear trough that settled after treatment with an energy-based device. Lumps are assessed with ultrasound before anything is done, as described on Juvelook lumps.
When can you wear make-up, exercise and use a sauna after Juvelook?
Make-up goes on once the injection points have closed and the bumps are flattening, applied lightly over intact skin and removed gently; a bruise is covered with concealer rather than worked over with a brush. Normal skincare can restart then too, but pause retinoids and exfoliating acids while the skin is tender, and do not start a new active product while the area is settling, because a reaction is harder to interpret.
Walking is fine straight away. Hard exercise, hot yoga, saunas, steam and alcohol wait until swelling has settled and any bruising has stopped spreading, because heat and raised blood pressure add to both. Facials, facial massage, gua sha, radiofrequency or laser over the same area are spaced as set out in your plan. Daily sunscreen continues throughout, and any bruise is kept out of the sun, because a bruise exposed to sun can leave a brown mark in Fitzpatrick III to V skin. Flying and travel timing are covered on flying after treatment.
When should you call the clinic after Juvelook?
Message the clinic on WhatsApp during clinic hours if you notice any of the following:
A bump that is getting larger rather than flattening.
A lump that is hard, tender or painful, whenever it appears.
Redness, heat or swelling that spreads, or fever.
Swelling that keeps increasing rather than settling.
Asymmetry that persists once swelling has gone.
A red, hot or painful lump needs a doctor the same day; if no doctor can see you today, go to a hospital emergency department. Skin turning white, grey or dusky near an injection point, severe pain, or any change in vision or eye pain is an emergency: call 995 or go straight to an emergency department, and do not wait for a message reply. Until you are seen, do not squeeze, massage or try to drain a lump, and do not have more product injected into the area. The complication care page sets out the signs in full. The review is timed once swelling has gone and collagen has had time to form, and any further placement is decided then.

After Juvelook, leave the injection points alone, use a cool compress for short periods, sleep with the head slightly raised and avoid make-up over the points, saunas, alcohol and hard exercise while swelling settles. Massage the area as you were shown, if at all. Use sunscreen daily and report any lump that grows, hurts or turns red.
The small raised bumps at each injection point flatten as the swelling settles; the time varies by area and person, so no fixed figure is given. A bump that is getting larger rather than smaller, or that becomes hard, tender or red, is not part of that settling and should be reported with a photograph.
Massage follows the instruction given at your visit, in the area and pattern you were shown. Juvelook is handled differently from Sculptra, which traditionally has a set massage routine, and some areas such as under the eyes are not massaged at all. Never knead a red, warm or painful bump; that needs assessment instead.
Walking is fine straight away. Hard exercise, hot yoga, saunas, steam and alcohol wait until swelling has settled and bruising has stopped spreading, because heat and raised blood pressure add to both. Light activity in between is reasonable. Stop anything that presses on the treated area or makes it throb.
Not fully. Hyaluronidase dissolves the hyaluronic acid carrier in Juvelook but not the PDLLA microspheres, so a nodule cannot be dissolved in the way a hyaluronic acid filler can. Lumps are examined, with ultrasound where needed, before any treatment is chosen; a red, hot or painful lump needs a doctor the same day.
The fullness seen on the day is mostly the hyaluronic acid carrier and water, and it fades. Any change from the PDLLA comes from collagen the skin builds gradually over months, and it varies between people, so it is judged at review once swelling has gone rather than in the first days.
