The Summer Skin Audit: Why You Need a Dermoscopy Mole Check Before 2026
New Zealand has the highest rate of melanoma in the world. It is a statistic we hear often, but it hits harder when summer arrives, the layers come off, and we notice spots on our skin that weren't there last year.
Mid-December is the busiest time of year for our clinic—not just for travel vaccines, but for patients concerned about "that weird mole on my shoulder."
At 1 Health, we believe that early detection is the only defence that matters. But not all skin checks are created equal. In this guide, we explain the difference between a quick glance and a medical-grade Dermoscopy check, and why "waiting to see if it grows" is the wrong strategy.
The "Ugly Duckling" Rule: What to Look For
Most of us know the ABCDE rule for melanoma (Asymmetry, Border, Colour, Diameter, Evolving). However, the most effective way to spot a problem early is often the "Ugly Duckling" sign.
Most of your moles will look like "siblings"—they will have a similar shape, colour, and style. If you have one mole that stands out—it’s darker, redder, or just looks different from the rest—that is your Ugly Duckling. It demands immediate professional attention.
Common Summer Warning Signs:
- New Moles: Developing new moles after age 40 is less common and should be checked.
- The "Pimple" That Won't Heal: A sore that bleeds, scabs, and heals but then bleeds again is a classic sign of Basal Cell Carcinoma (BCC).
- Itchy or Tender Spots: Moles shouldn't hurt. If one does, get it checked.
Why the "Naked Eye" Isn't Enough
Many patients ask, "Can't I just keep an eye on it myself?"
The problem is that by the time a melanoma is clearly visible to the naked eye as a "dangerous mole," it may have already grown deep into the skin layers.
At 1 Health, Dr. Bernard Teo (who holds a postgraduate Diploma in Dermatology and Skin Cancer Surgery) uses Dermoscopy for every skin check.
What is Dermoscopy?
A dermatoscope is a specialised medical lens that combines magnification with polarized light. It allows us to look through the surface reflection of the skin and visualize the pigment structures underneath.
Think of it like looking at a frozen lake. With the naked eye, you just see the ice (surface skin). With a dermatoscope, we can see what is happening in the water below (blood vessels, pigment networks, and chaotic structures). This technology increases the accuracy of melanoma diagnosis significantly compared to visual inspection alone.
What Happens at a Skin Check Appointment?
If you have never had a full skin check, it can feel daunting. Here is exactly what happens at our Wigram clinic:
1. The History We assess your risk profile. Have you had bad sunburns in the past? Do you have a family history of skin cancer? Are you on medication that suppresses your immune system?
2. The Scan You will undress down to your underwear (modesty is always preserved). The doctor will systematically check your skin from head to toe, including hidden areas like the scalp, behind the ears, and between the toes.
3. The Diagnosis If we find a suspicious lesion, we look closer with the dermatoscope.
- Green Light: It is benign (harmless). We can offer reassurance.
- Amber Light: It looks atypical. We may recommend monitoring it for 3 months or performing a Punch Biopsy to test a small sample.
- Red Light: It has features of skin cancer. We will recommend Excision (removal).
What If We Find Something? (Don't Panic)
The benefit of coming to 1 Health—rather than a "mole map" photography service—is that we can treat you right here. We are a Minor Surgery center.
If a mole needs removing, you don't need a referral to a hospital.
- Excision: We numb the area and remove the mole with a safety margin.
- Histology: Every single lesion we remove is sent to the laboratory for analysis to confirm the diagnosis.
- Cosmetic Closure: Dr. Teo uses advanced suturing techniques (like elliptical closures or flaps) to ensure the scar is as minimal as possible.

Prevention: The Best Medicine
While we are here to treat you, we would prefer to see you healthy. This summer, remember the basics:
- SPF 50+: Apply it 20 minutes before you go out, not when you are already at the beach.
- Timing: The NZ sun is harshest between 10 am and 4 pm.
- Cover Up: A hat and sunglasses are non-negotiable in Canterbury.
Start 2026 with Peace of Mind
Skin cancer is highly treatable when caught early. Don't let a nagging worry ruin your summer holiday.
