How to Do a Self-Skin Exam at Home

A self-skin exam is a simple, head-to-toe check of your skin that can help you notice new, changing, or unusual spots between professional visits. It does not replace a dermatologist’s exam, but it can make you more familiar with your own skin so changes are easier to recognize.

The best approach is calm, consistent, and thorough. Choose a well-lit room, use a full-length mirror and hand mirror, and give yourself enough time to look at areas that are easy to miss, including your scalp, soles, nails, and back.

Quick answer

• Check your skin from head to toe, including areas that do not usually get sun.
• Look for new spots, spots that look different from the others, or spots that change, itch, bleed, or do not heal.
• Use the ABCDE guide for moles: asymmetry, border, color, diameter, and evolving changes.
• Take notes or photos when helpful so you can compare over time.
• If you’re unsure about a spot, it’s worth getting checked by a board-certified dermatologist.

What a self-skin exam is

A self-skin exam is a visual review of your skin, moles, freckles, birthmarks, and other spots. The goal is not to label or diagnose anything at home. The goal is to notice what is new, what is changing, and what stands out from your usual pattern.

Many people find it helpful to do the exam the same way each time. That could mean starting at the face and scalp, moving down the front of the body, then checking the sides, back, legs, feet, and nails. A partner can help with hard-to-see areas, especially the scalp and back.

Common risk factors and changes to watch for

Skin changes can happen for many reasons, and not every new or changing spot is skin cancer. Still, certain patterns deserve attention. During your self-exam, watch for:

• A new growth, spot, bump, or sore that does not heal.
• A mole or spot that changes in size, shape, color, texture, or sensation.
• A spot that looks noticeably different from your other spots, sometimes called the “ugly duckling” sign.
• Itching, tenderness, bleeding, crusting, or repeated irritation without a clear reason.
• ABCDE changes in a mole: asymmetry, irregular border, multiple or uneven colors, larger diameter, or evolution over time.
• Spots on commonly missed areas such as the scalp, ears, lips, neck, underarms, palms, nails, groin, soles, and between the toes.

What you can do at home

Set up in bright light with a full-length mirror and a hand mirror. Remove makeup if needed, part your hair in sections, and check both the skin and nails. Move slowly and use the same order each time so the exam becomes easier to repeat.

• Start with the face and scalp. Look at the nose, lips, ears, eyelids, hairline, and scalp. A comb or hair dryer on a cool setting may help separate hair.
• Check the upper body. Look at the neck, chest, abdomen, shoulders, arms, elbows, underarms, palms, backs of hands, between fingers, and under fingernails.
• Use mirrors for the back. Check the back of the neck, shoulders, upper back, lower back, and buttocks.
• Finish with the lower body. Look at the legs, ankles, tops and soles of feet, between toes, and under toenails.
• Track what you see. Notes or photos can help you compare spots later, but they should not replace a medical evaluation when something seems concerning.

Professional options

A dermatologist can perform a full-body skin exam and evaluate spots that are new, changing, symptomatic, or difficult for you to monitor at home. Depending on what they see, common next steps may include closer observation, dermoscopy, medical photography, or a biopsy when clinically appropriate.

If you have a personal or family history of skin cancer, many moles, a history of significant sun exposure, tanning bed use, or spots that are changing, your dermatologist can help you decide how often professional skin checks make sense for you.

When to see a dermatologist

Book a dermatology visit if you notice a spot that is new, changing, bleeding, itching, painful, crusting, not healing, or different from your other spots. You should also schedule an evaluation if a mole develops ABCDE changes or if you simply cannot tell whether a spot is normal for you.

For Fort Lauderdale residents, snowbirds, and international visitors, it can be helpful to keep your skin check schedule consistent even when travel changes your routine. Bring any photos or notes you have, especially if a spot has changed over time.

FAQ

How often should I do a self-skin exam?

Many skin health organizations encourage a regular head-to-toe self-exam, often monthly. Your dermatologist can help personalize the timing based on your risk factors and skin history.

Can I tell if a mole is skin cancer by looking at it?

No. A self-exam can help you notice changes, but it cannot confirm a diagnosis. A dermatologist can evaluate the spot and recommend next steps if needed.

What tools do I need?

A bright room, full-length mirror, hand mirror, and good lighting are usually enough. Some people also use notes, a body map, or photos to compare spots over time.

Should I check areas that never see the sun?

Yes. Skin changes can appear in less visible areas, including the soles, between toes, nails, scalp, and areas covered by clothing. A careful exam includes the whole skin surface.

What should I do if a spot worries me?

Avoid trying to diagnose it at home. If you’re unsure, or if the spot is new, changing, bleeding, itching, painful, or not healing, schedule an appointment with a board-certified dermatologist.
