The patch acts as an adhesive bandage, creating a protective seal over the skin while also absorbing excess fluids like oil and dirt from your pimple. As it continues to soak up moisture and draw out all the impurities from your blemish, the hydrocolloid pimple patch will turn white.
Hydrocolloid Pimple Patches absorb oil, pus, and impurities from pimples, creating a moist environment that assists the skin. They act as a barrier and stop picking, which helps reduce the risk of scarring or breakouts.
What is hydrocolloid? It is a gel-like substance commonly used in medical dressings for its ability to absorb exudate—fluids such as pus and oil—from wounds. When applied to a pimple, the hydrocolloid patch draws out these impurities while maintaining a moist environment that promotes faster healing.
Besides providing a protective covering for the wound (a zit, in this case), hydrocolloid patches “pull excessive fluid out of the wound without sticking to the wound,” Del Campo explains. “Just like with wound healing, with acne you want to allow the skin to heal itself without adding to infection.”
Microcomedones are the smallest of all acne blemishes. These comedones are invisible to the naked eye and are the “seeds” from which larger comedones form.
Once your time is up, gently peel off the patch and throw it away. You should notice some white gunk on the patch. This is hydrocolloid gel that forms when hydrocolloid mixes with pus, bacteria, and oil.
The 'white stuff' that comes out of a blackhead or more commonly in pimples is pus. Pus is formed from inflamed debris, dead white blood cells and is also produced as the body's response to bacteria invading the system. This can it will heal on its own without treatment.
If your breakout hasn't been popped, a pimple patch can act as a helpful barrier to stop you from picking. Keep in mind that hydrocolloid patches are designed to work on open lesions, however, they can still prove effective at drawing out gunk from pimples that aren't open.
A: You can change it when your see your patch turning opaque as the pus and fluids collect on the patch. The patch only works if there is pus and fluid in your pimple (so whiteheads).
“For the individual giant cyst that starts to form, I recommend 'acne patches' which can draw fluid from and reduce the swelling of the cyst,” says Turner. “The patches are often made out of hydrocolloid materials that are super absorbent to help flatten the cyst.
There's no real 'rule' on how frequently you should be applying a pimple patch, they can really be used whenever needed. The frequency of use will also depend on your individual skin type and the severity of the breakouts you're experiencing.
A keratin plug is a small, often hardened mass that forms when the protein accumulates and blocks a hair follicle or pore.
Blackheads, or open comedos, are clogged pores that are filled with dead skin cells and oil, not dirt or grime as myth may suggest. The blackish portion of a blackhead — aka the sesame seed — is due to the oxidation of the dead skin cells and oil when exposed to air.
Dr. Lee uses the video to educate about the difference between a whitehead and a milia, which can sometimes appear quite similar. Milia are bumps containing keratin that has been trapped underneath the skin, and are sometimes called “baby acne” or “Epstein pearls."
Hydrocolloid is made of gel forming agents like pectin or gelatin (most commonly used) that create a moist environment with the body to promote healing. It draws out the fluids and pus and then forms a soft gel. If you've used Mighty Patch before, you'll notice this as the white stuff that gets sucked out!
Pimple patches are made with hydrocolloid, a gummy polymer typically used in wound care to absorb fluid and promote healing. “Hydrocolloid helps draw out oil and pus from pimples, reducing inflammation,” Dr. Wong says.
Covering pimples also reduces the likelihood of touching or picking at acne, a habit that can lead to scarring. By holding in moisture, hydrocolloid patches may also support the skin's natural healing process by keeping the area hydrated, further reducing the risk of scar tissue formation.
Your body can gradually break down pus and reabsorb its components. That's why small accumulations of pus (like in a pimple) often don't need treatment.
A comedo can be open (blackhead) or closed by skin (whitehead) and occur with or without acne. The word comedo comes from Latin comedere 'to eat up' and was historically used to describe parasitic worms; in modern medical terminology, it is used to suggest the worm-like appearance of the expressed material.
Can I pop a blind pimple? Never try to pop or squeeze a blind pimple. Doing so pushes the oil and bacteria deeper, causing more inflammation and increasing the risk of infection.
