You treated it. It went away. Then, a few months later, there it was again, in the exact same spot. Or a different sport. Or even worse: now there are three of them.
Warts are caused by a virus, as is another condition called molluscum contagiosum. Both conditions rely on the same two things to take hold: a way in through the skin, and an immune system that doesn’t shut the door fast enough.
Understanding why that keeps happening to you (or your child) is the first step to actually solving it.
Quick Summary
- Warts and molluscum contagiosum are both caused by viruses that exploit small breaks in the skin. Some people’s immune systems are simply slower to clear them.
- Factors like skin barrier damage, age, stress, and frequent exposure to communal environments all increase susceptibility.
- Most over-the-counter treatments target the visible lesion only, not the virus, which is why the same lesion (or a new one nearby) often comes back.
What actually causes warts to keep coming back?
Warts are caused by human papillomavirus, or HPV. This is not the same HPV associated with cervical cancer. There are over 150 strains, and the ones that cause common skin warts are different types entirely.
HPV can’t pass through completely healthy, intact skin. It needs a tiny opening: a small cut, a graze, a patch of softened skin after a long swim. Once inside, it infects the outer layer of skin cells and begins replicating, causing the thickened, rough bump you recognise as a wart.
The reason warts come back is that most treatments destroy the visible growth but do not eliminate the virus from the surrounding tissue.
The immune system, which was already slow to respond the first time, often doesn’t fully clear the infection. So the lesion returns, sometimes in the same spot, sometimes nearby.
What is molluscum contagiosum and how is it related?
Molluscum contagiosum (MC) is a separate viral skin condition caused by a poxvirus, separate from HPV.
But the underlying mechanism is similar: the virus enters through small skin breaks, infects cells in the outer skin layer, and produces small, round, pearlescent bumps, usually in clusters.
Like warts, molluscum spreads easily through:
- Direct skin-to-skin contact
- Shared towels, clothing or bath water
- Scratching, which transfers the virus to new areas
Both warts and molluscum respond well to Swift™ microwave therapy, which works with the immune system to clear the underlying virus.
What weakens your skin’s defences against viral skin lesions?
Skin barrier disruption
The outer layer of your skin is your first line of defence against any virus.
That skin barrier can be compromised by things like:
- Excessive dryness
- Excessive moisture (especially in communal environments like pools, gyms and change rooms)
- Eczema
- Minor abrasions
All of these factors give warts and molluscum contagiosum a much easier path in.
Immune suppression
Stress, illness, sleep deprivation and certain medications (particularly immunosuppressants and long-term corticosteroids) all reduce the immune system’s ability to recognise and respond to viral infections in the skin.
This explains why warts can suddenly appear or multiply during a stressful period.
Age and exposure history
Warts affect more than 40% of children at some point during childhood. That’s because children are in constant close physical contact with others, their skin is frequently grazed or softened during play, and their immune systems have not yet built up the response needed to clear viral infections quickly.
Older adults, on the other hand, may find their immune response slowing down as part of the natural ageing process, which is partly why warts can become more stubborn in people over 50.
How to protect your skin from viral skin lesions
You cannot make yourself completely immune to viral infections. It’s too common and too good at finding its way in. But you can make your skin a less welcoming host.
- Wear thongs or sandals in communal showers, gym change rooms, and at pools, where warm, damp surfaces and softened skin create ideal conditions for transmission.
- Moisturise regularly, particularly in winter. Dry, cracked skin on the heels and around the toes can create micro-openings for viral infections to enter.
- Avoid picking or scratching existing warts. Touching a wart and then another area of skin (known as autoinoculation) is one of the most common ways HPV spreads to new sites.
- Dry feet thoroughly after swimming or bathing, especially for children. Softened skin is significantly more vulnerable.
- Manage stress where you can. Chronic stress elevates cortisol, which suppresses immune function, including the skin’s ability to identify and fight off viral infections.
None of these steps guarantee you’ll never get a wart or molluscum contagiosum. But for people who find they keep getting them, addressing these factors alongside treatment can help break the cycle.
Swift™ is the most effective treatment for viral skin lesions
Many methods, like liquid nitrogen and over-the-counter treatments, target the lesion from the outside rather than the underlying virus. That’s why it keeps coming back.
More invasive methods, including injections, surgery, and laser removal, can be painful, leave open wounds, and require healing time.
On top of this, they also don’t have particularly high clearance rates.
Swift™ therapy targets the virus, not the skin. It delivers a precise dose of microwave energy into the infected tissue, raising the temperature rapidly enough to trigger an immune response. The body recognises the heat-stressed infected cells, identifies the HPV or MCV (poxvirus), and clears the virus systemically.
Clinical studies report clearance rates of 83% for warts using Swift™ therapy. For molluscum contagiosum in children, the Australian Wart Clinic’s data shows a 100% resolution rate in an average of just two visits.
Plus, there’s minimal discomfort and it doesn’t damage the skin, so you’ll be back on your feet straight away!
Let’s break the cycle
If warts or molluscum keep returning despite treatment, speak with a specialist who understands the viral mechanism behind them.
At Australian Wart Clinic, we assess each case individually and use Swift™ microwave therapy to give your immune system the trigger it needs to clear the infection properly.

FAQs about skin health and viral skin lesions
Does skin health affect your chances of getting warts?
Yes, significantly. The outer layer of skin is your primary barrier against HPV and other viral skin infections. When that barrier is compromised (through dryness, eczema, cuts, or prolonged moisture) viruses have a much easier path in.
Can stress cause warts to flare up or spread?
It can contribute. Chronic stress elevates cortisol. This suppresses immune function, including the skin’s ability to identify and respond to viral infections.
Why is molluscum more common in children with eczema?
Eczema disrupts the skin barrier, creating more entry points for the molluscum contagiosum virus. Children with eczema also tend to scratch affected areas, which both damages the skin further and spreads the virus through autoinoculation (touching one lesion and transferring it to a new area).
Can improving your skin health help clear viral skin lesions faster?
Supporting your skin barrier and immune system will not clear an existing infection on its own, but it creates better conditions for your body to respond. Keeping skin moisturised, managing stress, and avoiding habits that spread the virus all complement clinical treatment.
When should I see a specialist about a viral skin lesion?
If you’re unsure whether a lesion is a wart, molluscum, or something else entirely, see someone. Both conditions can resemble other skin issues, and treating the wrong thing can waste your time.
