If you’ve ever had cold sores (also called fever blisters), you know they tend to show up at the worst possible time. The culprit is the herpes simplex virus — usually Herpes simplex virus type 1 (HSV-1) for oral herpes, or Herpes simplex virus type 2 (HSV-2) for genital ulcers. Both stay hidden in your nerve cells, waiting for the right conditions to spark another herpes outbreak.
In our Cosmetic Tattoo Studio, Brisbane Face Figurati, we often see clients preparing for lip blush tattooing, only to have an unexpected cold sore outbreak derail their plans. By understanding what triggers reactivation, you can reduce recurrent outbreaks, protect your skin, and manage your health more confidently.

Cold Sore Virus: Key Facts
The herpes simplex virus is one of the most common infections in the world. It spreads through skin-to-skin contact, including kissing and oral sex, and can affect both the mouth and genitals.
- Type 1 (HSV-1): Usually causes herpes labialis (cold sores on the lips or around the mouth).
- Type 2 (HSV-2): More commonly linked with genital ulcers but can also affect the mouth.
Once the primary infection occurs, HSV never truly leaves. Instead, it hides in nerve cells, reactivating during times of stress, illness or other triggers.
Stat to know: Around 67% of people under 50 worldwide live with HSV-1, while HSV-2 affects about 13% of the global population. In Australia, HSV-1 is the leading cause of oral herpes, and HSV-2 is a big problem in women’s health.
Common Triggers for Viral Outbreaks
Let’s talk about what can wake the virus up.
Stress And Immune System Fatigue
Stress floods your body with hormones that weaken the immune system, making it harder to suppress HSV. Lack of sleep and poor recovery time add fuel to the fire.
Sun And Ultraviolet Light
The sun is a big trigger for herpes labialis. Ultraviolet light irritates the skin and nerves and can cause outbreaks. Think beach trips in Brisbane without SPF lip balm — a recipe for a flare-up.
Hormonal Changes And Women’s Health
Hormonal changes during menstruation, pregnancy or menopause can lower the body’s defences and cause recurrent episodes.
Illness, Fevers And Infections
A cold, flu or even atopic dermatitis flare-up can create an opening for HSV. Swollen lymph nodes, fatigue, and a weakened immune response often come before an outbreak.
Skin Trauma Or Cosmetic Procedures
Procedures like cosmetic tattooing, dental work or laser tattoo removal can disturb the skin barrier and wake up HSV. We always recommend antiviral medicine before lip procedures if you’re prone to cold sores.
Table: Common Triggers Vs Prevention Strategies
| Trigger | Why it happens | Prevention tip |
| Stress & fatigue | Lowers immune system response | Prioritise rest, self-care measures, and mindfulness |
| Sun/UV exposure | UV damages skin & nerves | Daily SPF balm, hats, and avoid harsh sun |
| Hormonal shifts | Weakened immune protection | Track cycles, pre-empt with antivirals |
| Illness & skin issues | The immune system is busy elsewhere | Support health with vitamin C and hydration |
| Cosmetic trauma | Disturbs nerve endings | Take antivirals before lip/skin treatments |
Real Studio Experience: A Client Story
One of our Brisbane clients booked a lip blush tattoo. She’d been careful with prep, but a cold sore outbreak hit the night before her appointment. The stress plus the upcoming skin trauma was enough to set HSV off.
We postponed, advised antiviral meds and rescheduled after healing. It’s a reminder: never ignore the first tingle. Tattooing over an active sore risks scarring and poor healing results.
Lifestyle Factors That Make Outbreaks Worse
HSV is opportunistic, and lifestyle plays a big part in how often it shows up.
- Diet and food triggers: Some people react to foods high in arginine (chocolate, nuts, shellfish). Lysine-rich foods (chicken, legumes, dairy) may balance it.
- Alcohol and smoking: Both weaken the immune system and skin recovery.
- Weather shifts: Cold winds or Brisbane’s sticky humidity can irritate lips.
- Contact dermatitis: Irritation from makeup, harsh skincare or allergens can lower defences.
The Outbreak Cycle: What To Expect
Cold sores follow a predictable timeline:
- Tingling (Day 1–2): Early activation of the herpes simplex virus.
- Blisters (Day 2–4): Painful fever blisters appear.
- Ulcer/oozing (Day 4–5): Blisters break into sores.
- Scabbing (Day 5–8): Lesions crust over.
- Healing (Day 8–12): Scabs fall off and skin heals.
Some recurrent outbreaks happen several times a year; others rarely experience symptoms after the primary infection.
Can Cosmetic Procedures Trigger Cold Sores?
Yes. Cosmetic tattooing, microneedling, or lip fillers disturb the skin barrier and can reactivate HSV in clients with a history of cold sores.
That’s why professional studios (like ours in Brisbane) have a strict protocol:
- We always ask about cold sore history during consultation.
- For lip blush, we recommend starting antivirals (e.g. aciclovir or valaciclovir) 1–2 days before treatment.
- If a client has an active outbreak, we reschedule
This isn’t about being fussy — it’s about client safety and healed results.
Treatment Options And Antiviral Support
No cure, but antiviral meds can shorten outbreaks and reduce recurrence.
- Antiviral creams: Applied early, they can reduce healing time.
- Antiviral tablets: e.g. aciclovir, valaciclovir.
- Daily suppressive therapy: For people with frequent recurrences.
- Anti-herpes meds: Keep outbreaks under control.
- Self-care: Ice packs, gentle lip balms, and avoiding triggers.
- Support groups: For the emotional side of living with HSV.
Herpes vaccines are being researched, but no Herpes Vaccine is available yet.
Taking Control Of Your Health
Living with HSV isn’t about fear — it’s about knowing your triggers, planning ahead and working with your health care provider when needed. Whether it’s antiviral meds, SPF, or mindful self-care, small steps reduce flare-ups and protect your skin.
In our Brisbane studio, we always ask about cold sore outbreaks before lip tattooing. It’s not just about healed results — it’s about keeping you safe, healthy and confident.

FAQ
Can food cause outbreaks?
Yes, certain food triggers like nuts, chocolate and caffeine can exacerbate symptoms for some people. Keep a food diary.
Does oral sex spread herpes simplex virus types 1 and 2?
Yes. Oral sex can transmit HSV-1 to the genitals and HSV-2 to the mouth. Avoid contact during outbreaks.
Can antiviral meds stop outbreaks completely?
They don’t cure HSV, but antiviral meds reduce outbreak frequency, shorten healing and lower transmission risk.
What’s the difference between a herpes rash and contact dermatitis?
A herpes rash usually appears as clustered blisters, while contact dermatitis shows as red, itchy patches caused by an irritant.
Is there a test to confirm herpes infection?
Yes. Lab tests or blood tests can confirm HSV type 1 or type 2. Test results guide the right treatment options.
