Replace the patch if it turns white As the patch absorbs pus and oil, it will turn white or opaque. Replace it with a fresh one when this happens.
As it continues to soak up moisture and draw out all the impurities from your blemish, the hydrocolloid pimple patch will turn white. That's when you'll know it's time to take it off and replace it with another one as needed.
“As the hydrocolloid gel adheres to the skin, it absorbs excess oil and dirt away from pimples,” said Hadley King, M.D., a board-certified dermatologist. Nonmedicated hydrocolloid patches may be worn for two to three days, as long as you change the patch every day.
Contrary to what pimple popping videos may show, squeezing your skin to extract the contents of a pimple — a mixture of oil, dead skin and bacteria — can cause scarring and infection. It can also worsen inflammation, making the pimple larger, more red and more painful.
A hydrocolloid plaster usually lasts between 3 to 7 days. A good indication to know when to change the dressing is by seeing how far it has come up from the edges of the wound.
Let the Patch Work: Leave the patch on for several hours or overnight. The patch will turn white in the center, indicating it has absorbed the pimple's exudate. Once this happens, it's time for you to remove and replace it!
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.
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.
Avoid picking or squeezing the popped breakout to let your skin heal naturally. If you notice any signs of potential infection like redness, increased pain, pus, or inflammation surrounding the blemish, contact a healthcare professional immediately.
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.
Hydrocolloid acne blemish patches work by absorbing the drainage from your pimples3. This then reacts with the gel-like substance of your bandage, forming a white bubble3.
“Pimple patches don't work at all on closed lesions or deeper lesions or even blackheads and whiteheads, which are called comedones,” Dr. Kassouf explains. “They are spot treatments for active bumps and have no ability to prevent acne from coming,” nor can they clear clogged pores or other precursors to acne flares.”
Dermatologist Leona Yip says patches can be a "good idea". "It's just selecting the right type of spot that would benefit." Dr Yip says pimple patches are best for "that pesky spot that won't go away" or "smaller acne spots", and they're not going to work on cystic or extensive acne.
The Science Behind Acne Patches: Mechanisms Explained
As they absorb impurities, including pus, they help reduce the size of the pimple and draw out contaminants. These convenient, easy-to-use pads don't contain any active ingredients or harsh chemicals, making them less likely to irritate sensitive skin.
Pimple patches are best used on clean, dry skin. They can be applied at any time of the day, but many people prefer to use them overnight for maximum effectiveness. However, they can also be worn during the day under makeup, providing a discreet way to treat blemishes while going about your daily activities.
It's tempting, but popping or squeezing a pimple won't necessarily get rid of the problem. Squeezing can push bacteria and pus deeper into the skin, which might cause more swelling and redness. Squeezing also can lead to scabs and might leave you with permanent pits or scars.
Pus is a natural part of the healing process for wounds. It is a sign that a wound is infected but it is also a sign that your body is trying to fight the infection and heal the injury. Once an infection has started, your immune system begins trying to fight it off.
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.
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."
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.
Plus, if you squeeze a zit that isn't ready, it could smear all the bacteria to adjacent locations, causing the spot to flare up again.
Squeezing the sebaceous filaments can lead to unintentional harm such as scarring or inflammation. Although they help to channel the flow of oil within a given pore, allowing it to come to the surface, ingredients like salicylic or glycolic acid help to keep them clean.
