Most adults should examine their own skin once a month and see a dermatologist for a full-body professional check once a year. If you have a personal history of skin cancer, many moles, fair skin that burns easily, a family history of skin cancer, or you take immunosuppressive medication, your doctor will likely recommend professional checks more often: every three to six months is common for higher-risk individuals. Self-checks do not replace professional exams. They are two different jobs. And if a spot is new, changing, bleeding, or just feels wrong to you, do not wait for a scheduled check. See a doctor.
For a broader look at the skin changes that matter most, see our guide to skin changes you should never ignore.
Key takeaways
A monthly self-check and an annual professional exam are the baseline. Higher-risk individuals need more frequent professional monitoring. And between scheduled checks, certain warning signs mean see a doctor now.
- Monthly head-to-toe self-exams help you know your skin's baseline so changes stand out.
- An annual professional skin check is the minimum for most adults. Higher-risk individuals (history of skin cancer, many moles, fair skin, family history, immunosuppression) should ask their dermatologist about every three to six months.
- Self-exams and professional exams do different jobs. Neither replaces the other.
- Any spot that is new, changing, bleeding, or painful should be seen by a doctor without waiting for a scheduled check.
- The plasma pen is for confirmed-benign spots only. It is not a substitute for professional evaluation of anything new, changing, or symptomatic.
How often should you check your skin?
The standard baseline: monthly self-check plus annual professional exam
The American Academy of Dermatology recommends a monthly head-to-toe skin self-examination for most adults. This is not a dermatologist-level assessment. It is a personal familiarity exercise: you get to know your skin so you can notice when something is different.
Once a year, a board-certified dermatologist (or your primary care physician, depending on your risk level) should do a full-body skin check. They can see things you cannot: spots on your scalp under hair, your back, the soles of your feet. A trained eye catches patterns your own familiarity might overlook.
That monthly-plus-annual structure is the starting point. For many people, it is not enough on its own.
When once a year is not enough: higher-risk individuals
Who needs more frequent professional skin checks
Certain factors raise your risk meaningfully and justify more frequent professional exams. The Mayo Clinic and dermatology guidelines consistently flag these:
Personal history of skin cancer. If you have had melanoma, basal cell carcinoma, or squamous cell carcinoma, annual checks are the floor. Many dermatologists move higher-risk patients to every three to six months.
Many moles or atypical moles. A high total mole count (generally considered 50 or more) or the presence of dysplastic (atypical) nevi increases your melanoma risk. Your dermatologist may recommend more frequent monitoring and may photograph your moles for comparison over time.
Fair skin, light eyes, or a history of sunburns. Skin that burns rather than tans has less natural UV protection, and cumulative sun damage is the primary driver of skin cancer risk.
Family history of skin cancer. First-degree relatives (parents, siblings, children) with melanoma or other skin cancers meaningfully elevate your own risk.
Immunosuppression. People who take immunosuppressive medications, including organ-transplant recipients, are at significantly higher risk for skin cancers and should follow their physician's recommended monitoring schedule, which is often more frequent than annual.
If any of these apply to you, your dermatologist is the right source for your specific recommended frequency. The monthly self-check still matters in between professional exams.
Self-checks and professional exams: two separate jobs
A self-check and a professional skin exam do different things. Collapsing them into one "check" is the most common misconception about this topic.
What a self-check does: builds your personal baseline. You know where your spots are, what they look like, and roughly when you first noticed them. That baseline is what lets you notice a change. A self-check does not give you the expertise to evaluate whether a spot is dangerous. It gives you the data point: this looks different than last month.
What a professional exam does: provides trained clinical assessment. A dermatologist uses a dermatoscope, knows what early melanoma looks like versus a benign seborrheic keratosis, and can biopsy anything ambiguous. No amount of self-checking replicates that.
Self-checking does not make professional exams less necessary. Professional exams do not make self-checking irrelevant. Both matter, and they work together.
Self-exams build the baseline. Professional exams evaluate what you cannot. You need both.
What to look for during your self-check
The ABCDE rule as your guide
The ABCDE rule is the most widely taught framework for evaluating spots during a self-check. We cover it in detail in our guide to the ABCDE rule for checking your spots, but the short version: Asymmetry, Border irregularity, Color variation, Diameter larger than 6mm, and Evolution (change over time). The last one is what a self-check is best positioned to catch: you noticed it changed.
What a spot that warrants attention looks like
A spot worth watching has changed in some way since you last noticed it. A spot that changed shape, a spot with an irregular or ragged border, a spot with more than one color, or a spot that has grown. Any of those changes is the signal to get a professional evaluation, not the shape or color alone in a single snapshot.
Good reference points: our guide to what a normal, benign spot looks like and our guide to benign spots vs skin cancer: how to tell the difference. Read both before your next self-check so you have a calibrated starting picture.
Spots that should not wait for your next scheduled check
The between-check triggers
The monthly rhythm is for systematic review. These situations are not wait-for-next-month situations: see a doctor.
See a doctor now if
- A spot that grew quickly in a short period. Rapid growth is one of the more consistent warning signals in the clinical literature.
- Any spot that bleeds without trauma (not from catching it on clothing or scratching). Bleeding, crusting, or oozing from a spot you have not disturbed is a reason for prompt evaluation.
- Any spot that is new and looks distinctly different from your other spots. The "ugly duckling" principle: a spot that stands out from everything else on your skin, even if it does not tick every ABCDE box, warrants a look.
- Any spot that is painful, itching, or scabbing repeatedly without healing.
- Any spot you simply cannot categorize as something familiar. If you cannot account for it, see a professional.
The NIH MedlinePlus skin conditions reference is a useful starting point for understanding when skin changes need clinical attention.
For confirmed benign spots: what comes next
If a dermatologist has examined a spot, confirmed it is benign, and you would simply like it gone, that is a different situation from the monitoring questions above. A confirmed-benign spot is not a watch-and-wait situation. It is a choice: leave it, have it removed clinically, or remove it at home.
For spots your doctor has confirmed are harmless (things like cherry angiomas, sebaceous hyperplasia, skin tags, age spots), read our guide to what a normal, benign spot looks like and our guide on when watch and wait is the right call. For those who have already made the decision to remove a benign spot at home, the OcuraLife Plasma Pen is designed for exactly this: a controlled, at-home treatment for confirmed-benign spots that takes about five minutes per spot, with a small scab forming by Day 3 to 7 and clear skin visible by Week 2 to 3.
The boundary matters: the plasma pen is for confirmed-benign spots only. It is not a substitute for professional evaluation of anything new, changing, or symptomatic.
Day 1
Treat and scab forms
About five minutes per confirmed-benign spot. A small protective scab appears the same day. Healing patches protect friction points.
The bottom line
Monthly self-checks plus an annual professional exam is the baseline for most adults. Higher-risk individuals (personal or family history of skin cancer, many moles, fair skin, immunosuppression) need more frequent professional monitoring, typically every three to six months, per their dermatologist. Self-checks build your personal baseline so you can notice change. Professional exams evaluate what you cannot. Between scheduled checks, any new spot that changes, bleeds, or simply does not look like the rest of your skin is a reason to see a doctor without waiting. Only after a professional confirms a spot is benign does at-home management enter the picture.
