Lumps after any skin booster: skin booster lumps.
The signs that are never normal after an injection: vascular occlusion warning signs.
Main guide Profhilo aftercare — the bumps, make-up, exercise and sauna rules, day by day.

Small raised bumps straight after Profhilo are part of the treatment, not a complication. The product is placed as a deposit at each injection point and spreads from there. A lump that grows, turns red and warm, or is still there after the others have gone is different, and should be examined.

Profhilo is not spread across the face in many tiny injections. It is placed as a deposit at each of five Bio Aesthetic Points on each side: the cheekbone, beside the nose, in front of the ear, the chin and the angle of the jaw. Each deposit sits under the skin as a raised bump until the hyaluronic acid, which is not cross-linked and flows easily, spreads through the tissue.
The bumps are therefore left alone. Massaging them is not part of the treatment. What to do day by day is on Profhilo aftercare.

| Expected bump | Needs to be seen | |
|---|---|---|
| When | Straight after treatment | Appears or grows later, or stays after the others have gone |
| Where | At the injection points | At one point, or away from the points |
| Look and feel | Soft, skin-coloured, flattening | Getting larger, firm, red, warm or tender |
| Skin over it | Normal, perhaps a small bruise | White, dusky, purple or net-like: this is urgent |
| What to do | Leave alone | Contact the doctor who treated you |
A lump that is still there once the other points have settled has a short list of possible causes: product that has not spread from one point, a bruise or collection of blood, a reaction to the product, or infection. They are told apart by examination, and by ultrasound where the answer is not obvious.
Profhilo is hyaluronic acid, so it can be broken down by hyaluronidase where that is the right step. That decision follows the examination. How dissolving is done here is on filler dissolving in Singapore.
A safety review by the manufacturer covered spontaneous reports from the first three years on the market, during which more than 40,000 patients were treated. Twelve adverse event reports were logged and none was classed as serious. Swelling, redness and bruising soon after injection were the most frequent; swelling and nodules appearing later came next, with two late-onset reactions. The reports were attributed to local hypersensitivity or injection technique, and all resolved (Cassuto 2020).
Two cautions apply. The review was written by authors linked to the manufacturer, and it relied on voluntary reports, so minor events are likely to be under-counted, as the authors themselves note.
Urgent: a change in vision or eye pain after an injection means calling 995 now. Skin that turns white, pale, dusky or mottled, or pain that is getting worse, needs the doctor who injected you, or A&E, now.
Redness that is spreading, warmth, pus at a point, or a bump that keeps getting larger needs a doctor the same day.
Not for emergencies. A change in vision or eye pain after an injection: call 995 now. Pale, dusky or mottled skin, or pain that is getting worse: go now to the doctor who injected you, or to A&E. Do not message or book for these signs.

WhatsApp Dr Sin Yong →or use the enquiry formRaised bumps at the injection points straight after Profhilo are expected. They are deposits of the product and flatten as it spreads. A lump that grows, turns red or warm, or persists after the others have settled is not expected.
They flatten on their own as the hyaluronic acid spreads through the tissue. A bump that is getting larger instead of smaller, or is still present once the other points have settled, should be examined.
No. The product is designed to spread on its own from each point, so the bumps are left alone.
Contact the doctor who treated you. Possible causes include product that has not spread, a bruise, a reaction or infection, and they are told apart by examination and ultrasound.
Profhilo is hyaluronic acid, which hyaluronidase breaks down. Whether dissolving is the right step is decided after the lump has been examined.
Skin that turns white, dusky or net-like, severe or increasing pain, or any change in vision after an injection needs urgent medical attention.
