Visible normal oil glands that appear as small pale or yellowish spots. Cold sores are small clusters of blisters on or around the lip, caused by the herpes simplex virus. The virus stays in the body for life, but episodes get shorter when treatment starts early, and for most people they become less frequent over the years.


The same eight facts on every condition comparison.

Fordyce Spots Small yellow-white dots line the upper lip surface.

Blister cluster Small blisters on the lip edge.

Crusting Yellow crust as it heals.

Near the nose Can appear around the nostrils.
Normal oil glands become visible where they are not associated with a hair follicle. They are a harmless anatomical variation rather than an infection.
Herpes simplex virus remains in sensory nerves after the initial infection. Reactivation brings the virus back to nearby skin, where local viral activity can produce grouped blisters.
Fordyce Spots. Often becomes noticeable around puberty or early adult life.
Cold Sores. The first infection often occurs early in life; recurrent episodes can occur at any age afterward.
A harmless normal anatomical variant, rather than an infection.
Cold sores are caused by the herpes simplex virus. After the first infection, the virus stays in nerves and can reactivate.
Confirmed Fordyce spots need no medical treatment. Cosmetic procedures can carry risks of pigment change and scarring; do not squeeze them or apply wart-removal products.
Fordyce spots are normal visible oil glands and often persist. They do not need treatment; cosmetic removal can cause pigment changes or scars and does not prevent all new spots.
Most episodes run a week to ten days. People settle into a rhythm - one or two a year, or several, and some have one episode and never another. Frequency drops with age.
These are not sexually transmitted and do not require treatment when diagnosis is secure.
Herpes can occasionally spread to the eye or extensively through eczema-affected skin. Eye pain, widespread painful blisters, or exposure of a newborn requires prompt medical advice.
Have new, painful, ulcerated or changing genital bumps examined to confirm the diagnosis.
Seek care for severe, frequent or persistent episodes. Eye pain or redness, widespread blisters with eczema, or illness in a newborn needs urgent assessment.

Leave the bumps alone; do not squeeze, burn or use wart-removal acids.
Have new, painful, ulcerated or changing genital bumps examined to confirm the diagnosis.
Almost certainly in childhood, from ordinary contact with someone who carried the virus - a kiss, a shared cup or spoon. Most people have no memory of it, because the first infection often causes nothing. It is not about hygiene or anything you did.
Most easily passed on from when blisters appear until the sore has fully crusted - roughly the first four to five days. Small amounts are shed when nothing is visible. Precautions matter most around newborns, eczema and anyone immune-suppressed.
Because the virus lives in one nerve, which supplies one small patch of skin. When it reactivates it travels down to that patch. Some people have two or three usual spots.
The virus stays in the body permanently, so there is no cure. But episodes usually become less frequent over the years, and daily suppressive treatment can reduce them a great deal. Plenty of people effectively stop having them.
Not while you have an active sore. Herpes simplex is dangerous in newborns in a way it is not in older children or adults. Do not kiss the baby, wash your hands before handling them, and cover the sore. If a newborn develops blisters or a fever, or becomes unusually sleepy or floppy, that is an emergency.
Less well. Antiviral tablets stop the virus multiplying, and by the time blisters are out most of that has happened. Still worth taking for a severe episode, but the benefit is in the first 24 hours.
