There are a few reasons why it may take time to heal a big pimple.
It’s normal for some types of acneespecially deep, largepimplesto take longer to clear up.
Breakouts happen whenporesin your skin get clogged with excess oil and skin cells.

Verywell
Sometimes, bacteria can get into your pores and become inflamed and infected.
The main difference is that acne nodules do not contain fluid.
They are more solid and firmer than acne cysts, which are filled with puss.
First and foremostdon’t ever have a go at pop a deep pimple.Don’t poke it with a needle.
Don’t squeeze it.
Squeezing, poking, or otherwise messing around with the blemish makes thehealing timelonger.
A pimple typically heals on its own in three to seven days.
However, if you pop the pimple, it can become infected and take longer to heal.
It can also push dirt, dead skin cells, and other debris deeper into your pore.
This can cause the follicle wall to break and allow infected material to spread in the skin.
As much as you might like to, don’t attempt to drain your pimple.
There’s no need to use too much, though; limit yourself to a twice-daily system.
Using too much medication too often can dry out and irritate your skin rather than heal it.
Be aware, however, that spot treatment works best for pustules.
It won’t do much for deep nodules or cysts.
What About Home Remedies?
Never treat blemishes with items not meant for the skin.
Home remedies can’t get deep enough into the skin to do any good.
At best, they’ll do nothing for the blemish.
At worst, you’ll end up with an irritated spot or a red and itchy rash calledcontact dermatitis.
Warm Compresses
You may be able to soothe stubborn pimples by applying a warm compress.
Make one by soaking a washcloth in really warm water.
Apply it to the pimple for 20 minutes or so, a couple of times a day.
You might have to do this for several days.
The warm compress can help the pimple to drain on its own.
Remember, though, don’t squeeze at the pimple even if it comes to a head.
Let it drain naturally.
This immediately decreases inflammation.
Don’t put ice directly on your skin.
Instead, wrap ice cubes or an ice pack in a clean cloth.
you’re free to also use a chilled tea back.
Put pressure on the pimple with the ice for 10 minutes.
Repeat the system two more times with 10-minute breaks in between.
If you have a breakout, avoid exposing your blemished skin to the sun.
Acne Surgery
Your dermatologist may recommendacne surgery.
Deep cystic breakouts sometimes need to be lanced (cut open) and drained by a medical professional.
It is important to have this done by a healthcare professional.
Within a few days, the pimple shrinks and disappears.
Cortisone injections are not right for every person or every blemish.
Check with your dermatologist to see if this is a good treatment for you.
Conditions That Resemble Acne
Many other skin problems cause acne-like blemishes.
Your healthcare provider will be able to tell if it is acne or one of these conditions.
Some boils heal on their own with at-home treatment, but others need medical attention.
Ingrown Hairs
Ingrown hairs (pseudofolliculitis) are also easy to mistake for persistent pimples.
They can cause large, painful, red bumps, especially if the follicle becomes infected.
They’re more common in areas where you shave.
However, they’re two completely different skin blemishes.
Cold sores are triggered by the herpes simplexvirus.
Whileacne can’t be spread from person to person, the virus that causes cold sores is contagious.
Skin Cancer
Sometimes, acne that won’t go away is a more serious health condition.
Larger pimples that are deep under the skin can take longer to heal.
Try using a spot treatment or applying a warm compress a few times a day.
If that doesn’t help, your dermatologist may recommend another treatment.
However, acne that isn’t getting better can also be a sign of a bigger problem.
