Are Dermal Fillers Safe? Risks & Contraindications Explained

Common, Mild Side Effects

Right after treatment, it’s typical to experience some temporary symptoms such as:

• Redness, swelling, or bruising at injection sites.
• Tenderness or mild discomfort.
• Slight itching or a rash.
• A feeling of firmness under the skin.
• Minor asymmetry or lumps that often resolve on their own.

These reactions usually appear shortly after the injections and fade within days.

Less Common, More Serious Risks

While rare, more severe complications have been reported, including:

• Nodules or firm bumps under the skin.
• Skin necrosis or tissue damage where blood flow is compromised.
• Draining wounds or sores at injection sites.
• Allergic reactions, possibly to the filler material.
• Migration of filler to other areas.
• Blockage of blood vessels, which can cause tissue damage or, in extreme cases, vision impairment or stroke.

Such serious events are uncommon, but they reinforce the need for expertise, proper technique, and immediate follow-up care if anything feels wrong.

Contraindications — When Fillers Are Not Advisable

Certain conditions or circumstances may make dermal fillers unsuitable, such as:

• Redness, swelling, or bruising at injection sites.
• Tenderness or mild discomfort.
• Slight itching or a rash.
• A feeling of firmness under the skin.
• Minor asymmetry or lumps that often resolve on their own.

These reactions usually appear shortly after the injections and fade within days.

How To Minimise Risk & Stay Safe

• Choose an experienced and accredited practitioner.
• Be honest about your medical history and medications.
• Avoid blood-thinning medications or supplements (if medically safe) in the days around treatment.
• Report any unusual pain, lumps, colour changes, or skin discolouration immediately.
