Regularly photographing your moles is key to detecting changes early. But how often should you actually do it? The answer depends on several factors — most importantly, your individual risk level.
General recommendation: every 3–6 months
For most people, a photo session every 3 to 6 months is a good balance. It's frequent enough to catch the evolution of a mole (the "E" criterion of the ABCDE rule), yet not so frequent that it becomes a burden.
J-Skin sets a default reminder for 6 months after your last photo. You can adjust this individually for each mole.
When should you photograph more often?
Some people should monitor their moles more frequently — even every 1–2 months:
- Fair skin that burns easily in the sun
- A large number of moles (more than 50 on the body)
- Atypical moles — irregular, multicoloured, or larger than 6 mm
- Family history of melanoma (parents, siblings)
- History of severe sunburns in childhood
- A new or rapidly changing mole — check every 2–4 weeks in that case
When is less frequent enough?
If you have darker skin, few moles, and no family history of melanoma, a session every 6–12 months may be sufficient. What matters most, however, is sticking to a consistent schedule — regularity is more important than the exact interval.
How J-Skin helps you stay consistent
- Automatic reminders — the app sends a notification when it's time for your next photo. Each mole has its own counter.
- Ghost overlay — when taking a new photo, you see a semi-transparent preview of the previous one. This helps you position your phone exactly as you did before.
- Auto-alignment — even if the new photo is slightly off, the algorithm automatically aligns it to the previous one.
- 4 comparison modes — slider, press-and-hold, blink, and change heatmap make it easy to spot differences.
What to look for when comparing
At each session, pay attention to:
- Change in size — J-Skin measures automatically in millimetres
- Change in shape — have the edges become less regular?
- Change in colour — has a new shade appeared? Is part of it lightening or darkening?
- New symptoms — itching, bleeding, crusting
Even a small change visible in photos — but not noticeable to the naked eye — is a good reason to show the mole to a dermatologist.
Summary
- Standard: every 3–6 months
- Elevated risk: every 1–3 months
- New or changing mole: every 2–4 weeks until you see a doctor
- The key is consistency, not the perfect interval
Frequently asked questions
How often should I photograph my moles?
For calm monitoring, a photo every few months is usually enough, and J-Skin reminds you every six months by default. You can change the interval for each mole. If you notice a fast change in shape, color or size, do not wait for the due date and see a dermatologist.
How do I take repeatable photos?
Shoot in daylight, without flash, from the same distance and angle. Place a coin beside the mole as a scale and white paper to steady the colors. J-Skin shows the previous photo as a semi-transparent overlay and helps you match the framing, which makes comparison over time easier.
Do many moles require more frequent photos?
Not necessarily more frequent, but more systematic. With many moles it is easy to miss something, so photograph them one by one and note their location. People with numerous moles or higher risk should agree on a check schedule with a dermatologist. The app organizes observations but does not replace a doctor.
