TLDR: depends but usually for a new acne lesion to be gone it could be 1-2 weeks.
What is acne?
Acne is a skin condition that occurs when follicles in the skin become clogged with oil (sebum), dead skin cells, and sometimes bacteria. It can cause skin problems such as whiteheads and blackheads and can cause scarring.
Although it’s mostly seen in teenagers aged 13-20 — the age at which acne is most common and severe — acne can affect people of all ages. For most people, acne goes away over time with age and a proper skincare regimen. It can occur anywhere you have skin, including the face, neck, shoulders, and back. Risk factors for acne include a change in hormones during puberty, PCOS, anxiety, diet, stress, and genetics.
What causes acne?
Acne can be caused by several factors. These include hormonal changes during puberty, such as an increase of the hormones (androgens) that increase the size of the skin’s oil glands and the rate of production of oil (sebum), PCOS, genetics, anxiety disorder, stress, and allergic reactions.
Because the causes of a person’s acne will be unique to them, their treatment should be personalized. What works for you may not work for another person whose acne is caused by something different. Effective treatments are available but acne can be very persistent and you may need to be on treatment as long as you are hormonal (usually through the teen years and sometimes into your college years).
When does acne stop?
It’s common for acne to start between the ages of 10 and 13 and to last for 5 to 10 years or throughout your adult life (depends on your family history). Acne normally goes away with age but may require treatment for at least 5-10 years. Ask your doctor about prescription acne treatment. It beats anythnig they have over-the-counter.
Although these are statistical averages, it’s impossible to guess how long acne will last for each individual person. Many teens and young adults find that their acne improves as they get older and others have acne into their adult years.
How long does it take for a pimple to form?
Normally, pimples can take anywhere between 1-2 weeks to fully develop and form. It may seem that they form overnight, but in reality it’s a very long process that involves weeks of development.
What’s the life cycle of a pimple?
Acne starts as microscopic bumps called microcomedones that can’t be seen with the naked eye. Oil glands within the skin are stimulated by hormones and enlarge to become overactive and pump out excess oil. Many infected blemishes come from preexisting whiteheads or pimples that are already present in the area within the pores. Bacteria can get stuck behind the blockage and multiply as the skin begins to become inflamed with bacteria, inflammatory cells, and oil.
How long does it take a pimple to go away?
Most pimples take 1-2 weeks to go away on their own. Some can take up to 6 weeks. Although they can’t be cured overnight, they can be treated with many different methods that have been proven to work such prescription acne treatment like tretinoin and topical antibiotics.
What is the best acne treatment?
The best acne treatments are those that:
- decrease oil production
- make the pores smaller
- make the cells less sticky
- drain the acne lesion (comedolytic)
- decrease the effect of hormones
- kill the bacteria
The first-line treatment for all acne should be a product containing a retinoid (like topical tretinoin, adapalene, etc) as retinoids offer all of the benefits listed above except the final two. For over-the-counter treatment, look for products that contain benzoyl peroxide or alpha hydroxy acids as active ingredients. Usually, it takes 6-8 weeks of product use to see any improvement. Other treatments you can access without seeing a doctor can include:
- avoiding touching your face
- applying warm compresses to big acne lesions
- using acne spot treatment creams (benzoyl peroxide, salicylic acid), or creamy toothpaste or baking soda (make a paste with less than 2 teaspoons of baking soda and water, put on zit for 20 minutes).
- washing your face and other acne-affected skin regularly (1-2 times a day maximum). However, if you wash too much, it can cause more oil to be made, so it’s important to find a balance.
- changing your diet (but only if you notice a specific food makes it worse)
Sometimes, you may need to get further medical support from your doctor. After a doctor or dermatologist reviews your acne, you may be prescribed:
- a medical acne treatment
- cortisone shots

Here are some acne treatments available through Pandia Health:
Tretinoin (topical retinoid)
One option for acne treatment is tretinoin cream (also available as a gel), which is commonly used to treat acne and sun-damaged skin. It also improves the appearance of surface wrinkles and dark spots. Tretinoin is also known as a retinoic acid, which speeds up the life cycle of skin cells by making them divide faster, so newer cells can grow in their place. It’s much stronger than typical over-the-counter acne treatments so must be prescribed by a doctor or medical provider. It is suitable for normal, combination, and sensitive skin.
Research shows that tretinoin exfoliates the skin, reduces inflammation associated with acne, prevents clogging of pores altogether, and can make existing acne lesions disappear. You apply tretinoin once a day (preferably before bed) to the areas where your acne pimples usually appear. Avoid using tretinoin at the exact same time as benzoyl peroxide, salicylic acid, astringents, lime, spices, and alcohol because they will kill its efficacy and prevent it from helping your acne.
Clindamycin lotion (Topical Antibiotic)
Clindamycin is an antibiotic that kills Cutibacterium acnes (the bacteria that makes acne worse). Before recommending oral antibiotics, your doctor will prescribe topical antibiotics, which are applied directly to the skin. Clindamycin will kill the bacteria, decreasing acne and redness. It also has an anti-inflammatory effect.
Be careful if using Clindamycin all over your body as it’s possible for it to affect your gut, causing a diarrhea infection. This is a very rare side effect, but one to watch out for.
Doxycycline is a tetracycline-family antibiotic that kills bacteria within the body, including in the follicles (where hair grows out from) and oil-filled pores. It’s also used to treat bacterial infections such as acne, chlamydia, syphilis, gum disease, and urinary tract infections. Although Doxycycline is a great method to control the bacteria in your pores and body, doctors and Pandia Health don’t recommend using it for more than 12 weeks at a time because of the risk of antibiotic resistance. Theoretically, oral antibiotics might affect your hormonal birth control just like any other antibiotic, but research has shown that only griseofulvin and rifampin truly affect birth control.
Doxycycline is prescribed as an oral pill to be taken once or twice a day with a full glass of water. There have been a few case reports of esophagitis, which is when a pill eats through the side of the esophagus because the patient didn’t drink enough water with the pill. Although it is an antibiotic, it’s also useful against the inflammation caused by acne. This is a short-term treatment method so once the skin improves, your doctor will stop prescribing Doxycycline. Don’t take Doxycycline if you’re pregnant (it’s pregnancy category D), or allergic to tetracyclines, and don’t give it to children under 8 years of age.
Everyone who has acne will have a different experience. As such, the treatment you receive should be tailored for your unique experience. It’s important to remember that acne is extremely common. Most people you know will have experienced it at one point in their lives and may even still be going through it.
While acne can’t be cured overnight, it can be managed with a combination of the right holistic treatments and medication. If needed, you can have a doctor prescribe more powerful acne treatments like tretinoin and topical antibiotics.
