How to do a Skin Self-exam
Checking your skin regularly can help you notice any unusual changes. Follow your health care provider's recommendations on how often to check your skin.
These tips may be helpful:
- The easiest time to do the exam may be after you bathe or shower.
- If you are a woman and do regular breast self-exams, this is also a good time to check your skin.
- If possible, use a full-length mirror in a room with bright lights so you can see your entire body.
Look for these things when doing a skin self-exam:
New skin markings:
- Changes in color
Moles that have changed in:
Also look for "ugly duckling" moles. These are moles that look and feel different from other nearby moles.
- Uneven edges
- Differences in color or asymmetric colors
- Lack of even sides (look different from one side to the other)
Also look for:
- Moles or sores that continue to bleed or will not heal
- Any mole or growth that looks very different from other skin growths around them
To do a skin self-exam:
- Look closely at your entire body, both front and back, in the mirror.
- Check under your arms and on both sides of each arm. Be sure to look at the backs of your upper arms, which can be hard to see.
- Bend your arms at the elbow, and look at both sides of your forearm.
- Look at the tops and palms of your hands.
- Look at the front and back of both legs.
- Look at your buttocks and between your buttocks.
- Examine your genital area.
- Look at your face, neck, back of your neck, and scalp. Use both a hand mirror and full-length mirror, along with a comb, to see areas of your scalp.
- Look at your feet, including the soles and the spaces between your toes.
- Have a person you trust help examine hard-to-see areas.
