Dr. Google at 3 a.m. You know the feeling.
That little lump appeared out of nowhere and now your life is over. Is it fungal? Cystic? Malignant?
Most likely it is nothing. Just a bug bite masquerading as a health crisis. But curiosity is a nasty bug too.
“It’s important to spot the one lone duckling,” Mona Gohara, MD notes. If a spot looks odd, weird, or unlike its neighbors, see a derm.
Self-diagnosing is fun but dangerous. Leave the medical diagnoses to the people with the degrees. Debra Jaliman. Joshua Zeichner. Tsippora Shainhouse. They are the brains.
But we are impatient creatures. Waiting for an appointment takes too long.
Here is what you might be touching right now.
Keratosis Pilaris
The Sandpaper Effect.
Small bumps. Skin colored or red. Upper arms and thighs. Rough as hell. Not painful, usually just annoying.
Caused by keratin. It clogs the pores like a traffic jam because your skin isn’t shedding like it should.
Can’t cure it. Can manage it.
* Use a cleansing brush.
* Apply lactic or salicylic acids.
* Moisturize heavily. Dry skin makes it worse.
Cherry Angiomas
Red dots on the map.
Harmless red bumps made of blood vessels. Face. Chest. Belly.
We don’t know why they appear. Genetics? Maybe. Aging? Definitely. Most people over 75 have them. Pregnancy hormones can make them grow faster and larger.
Leave them alone. They aren’t dangerous. If they bother you aesthetically, a laser can zap them off in the office.
Dermatofibroma
The Scar That Isn’t.
Hard pink or brown lumps. Lower legs are prime real estate. Technically scars, though you might not remember the injury.
Caused by ingrown hairs, bug bites, or random trauma. Sometimes pregnancy triggers them. Rarely linked to autoimmune issues or HIV.
Usually benign. If they hurt or itch, surgery removes them. If you have many of them, tell your doctor. It might point to lupus.
Actinic Keratoses
The Sun Warning.
Listen up. These are precancerous. Rough. Scaly patches on sun-exposed areas. Face. Hands. Arms.
Caused by decades of UV damage and tanning bed abuse. Wear sunscreen SPF 30+. Every day.
If you ignore these, 5-10% might turn into squamous cell carcinoma. Don’t be that statistic. Go to a derm now. Cryotherapy freezes them off. Or prescription creams work.
Calluses
Armor plating.
Thickened skin on hands or feet. Nature’s response to friction. Pressure. Irritation.
Usually painless. Just ugly if you want them gone.
Pumice stone your way to freedom. Or urea cream. Or lactic acid.
Dr. Gohara’s trick: Vaseline, callus remover, wrap it in plastic, put on socks. Walk around until softened. And buy shoes with toe room. Seriously.
Keloids
Scars with a mind of their own.
Thick scar tissue that grows way beyond the original wound. Earlobes. Chest. Cheeks.
They itch. They hurt. Darker skin tones get them more often. Caused by acne, piercings, surgeries.
Hard to treat. Liquid nitrogen. Steroid injections. Lasers. Surgery often makes it worse because it’s… trauma. So think before you cut.
Moles
The usual suspects.
Brown spots made of melanin. Genetics dictate them. Fair skin means more of them.
Leave them alone unless.
If it changes color. Bleeds. Gets irregular. Get it checked immediately.
Moles can turn into skin cancer in the sun. Annual checks with a board-certified derm are cheap insurance.
Lipomas
Doughy pockets.
Soft. Movable lumps of fat under the skin. Harmless. Common.
Not linked to being overweight. You won’t burn them off by hitting the gym. They just sit there.
If they hurt or get too big, surgery cuts them out. Liposuction can sometimes suck them up. Otherwise, ignore them.
Folliculitis
Pity your follicles.
Inflamed bumps. Looks like acne but is really angry hair follicles. Butt cheeks. Groin. Areas of sweat and friction.
Caused by bacteria. Tight clothes. Dull razors. Not showering after workouts.
Treat with benzoyl peroxide washes. Prescription lotions if that fails.
Home hack for itch: Cool water mixed with white vinegar. Soak a compress. Apply twice daily for 15 minutes. Works better than you think.
Acne
Old news, new drama.
Whiteheads. Blackheads. Cysts. All variants of the same clog. Oil and dead skin trapping bacteria deep down.
Benzoyl peroxide kills bacteria. Salicylic acid unclogs pores.
Retinoids? Prescription only but powerful. Tretinoin. Isotretinoin. Talk to a pro before going nuclear on your face.
Ingrown Hairs
The boomerang.
Hair curves back into skin. Red bump. Painful.
Common in curly hair textures due to shaving angles.
Extract with tweezers if visible. Clean it. Antibiotic ointment. Then stop shaving that spot until it heals. Takes weeks. Sometimes months. Retinoids help clear the path for next time.
Skin Tags
Fleshy appendages.
Harmless flaps on neck. Armpits. Eyelids. Rub against jewelry and they get red.
Genetics. Friction. Sometimes diabetes or weight play a role.
Do not rip them off yourself. Bleeding happens. Ask a derm to freeze or cut them safely.
Seborrheic Keratosis
Age spots that look like warts.
Brown or tan. Waxy. Scalloped edges. Chest. Back. Bra lines.
Not cancer. Just old. Genetics plus sun exposure equals more of these. Usually pops up after 50.
If they itch or irritate, freeze them. Burn them with electric current. Shave them off.
Blisters
Fluid-filled sacs.
They form when
