You undress to your underwear. A dermatologist looks at your skin systematically from head to toe. It takes 15-20 minutes. That's it.
If you've been putting off a skin check because you don't know what happens, here's the reality: it's straightforward, professional, and over quickly. The mystery is bigger than the appointment.
Do I really need to undress completely?
You undress to underwear. That's standard. Cancer Research UK confirms this is necessary because skin cancer can develop anywhere on your body, including areas not exposed to sun.
The dermatologist needs to see your entire skin surface. Hidden melanomas account for 10-15% of cases, often appearing between toes, on the scalp, or in areas you'd never think to check yourself. You'll be given a gown that opens at the back, similar to any other medical examination.
Most clinics provide disposable underwear if you prefer. The examination room is private, and only the examining clinician is present unless you request otherwise.
What does the dermatologist actually do during the examination?
They look. Systematically. Starting from your scalp and working down to your feet, including between your toes. According to NHS England guidance, this follows a standardised protocol used across clinical practice.
The dermatologist uses bright lighting and often a dermoscope (a handheld magnifying device) to examine any moles, freckles, or skin changes more closely. They're looking for asymmetry, irregular borders, colour changes, diameter changes, and evolving characteristics - the ABCDE criteria.
If they find anything concerning, they'll point it out and explain what they're seeing. Most findings are benign, but anything suspicious gets documented and may require a biopsy for definitive diagnosis.
How long does a skin check appointment take?
15-20 minutes for a routine check. Research published in the British Journal of Dermatology study confirms that thorough whole-body examinations typically fall within this timeframe.
Specialist dermatology appointments may take 20-25 minutes, while GP skin checks are often completed in 10-15 minutes. The actual examination is 10-12 minutes - the rest is discussion, questions, and any follow-up planning.
If you have many moles or a family history of skin cancer, expect the longer end of this range. If the dermatologist finds something requiring immediate attention, the appointment may extend, but you'll be informed beforehand.
Will it hurt or feel uncomfortable?
No physical discomfort. The examination is entirely visual and non-invasive. The dermoscope touches your skin lightly but causes no pain - it's like having a magnifying glass pressed gently against your skin.
The main discomfort is psychological. Undressing for medical examination causes anxiety for many people, which research shows is the primary barrier to attending skin cancer screening. This anxiety typically disappears within the first minute of the appointment.
Room temperature is kept comfortable, and you're only undressed for the examination portion. The dermatologist will talk you through what they're doing, which helps normalise the process.
What happens if they find something suspicious?
First, don't panic. Most suspicious-looking lesions are benign. The dermatologist will explain what they've found and why it needs further investigation.
If a biopsy is needed, it's usually done immediately or scheduled within a week. Local anaesthetic is used, and the procedure takes 5-10 minutes. You receive results within 1-2 weeks.
For benign findings that look unusual, you might be scheduled for monitoring appointments every 6-12 months. Photography is often used to track any changes over time.
Early detection significantly improves outcomes. Melanoma caught early has a 99% five-year survival rate, which is why these examinations are so valuable.
Should I prepare anything beforehand?
Remove nail polish from fingers and toes - dermatologists need to examine nail beds where melanoma can hide. Arrive with clean skin, free from makeup, fake tan, or body lotion.
Make a mental note of any moles or skin changes you've noticed. Write them down if helpful. Most people forget to mention things once they're in the appointment.
If you have numerous moles, consider having baseline photographs taken. Our skin check service includes professional mole mapping for ongoing monitoring.
How often should I have skin checks?
Annual checks for most people. Every 6 months if you have risk factors: fair skin, family history of skin cancer, history of sunburn, or numerous moles.
High-risk individuals may need quarterly checks initially, then move to six-monthly once a baseline is established. Your dermatologist will recommend the appropriate interval based on your individual risk profile.
Between professional checks, examine your own skin monthly. You know your skin better than anyone and are most likely to notice changes.
Key Takeaways
- Standard skin checks involve undressing to underwear and systematic visual examination
- Appointments last 15-20 minutes with 10-12 minutes of actual examination
- The procedure is non-invasive and painless
- Most findings are benign, but early detection dramatically improves outcomes
