How long does it take for skin to purge? Unfortunately, purging can be a lengthy process and it can take up to three or so months before results start to show, especially if the treatment is an acne medicated treatment.
It may not be easy to tell the difference between skin purging and breaking out since they both involve acne. However, the key difference between breakouts and skin purging is that skin purging is temporary and usually occurs after you have incorporated a new ingredient in your skincare routine, Green says.
Be patient for one skin cycle, or about 28 days
Everyone's skin is unique, so that time frame can differ from person to person. Generally speaking, dermatologists say purging should be over within four to six weeks of starting a new skin care regimen.
Unfortunately neither a breakout or a purge is going to disappear overnight. “Your skin cycle lasts for around 28 days and a typical skin purge can last anywhere between four and six weeks,” says Kate.
Signs your skin is purging
Your breakouts cleared up much faster than your usual acne or pimples. Your breakouts did not leave marks or blemishes on your skin. All the breakouts seemingly started all at once. The breakouts settle down in 2-3 weeks and your skin appears clearer and healthier.
Skin purging occurs when you start using a new product that contains chemical exfoliants such as alpha-hydroxy acids, beta-hydroxy acids, and retinoids, all of which speed up the rate of skin cell turnover (the rate at which you shed dead skin cells and replace them with new cells), says Dr. Gonzalez.
If you want to prevent skin purging or limit a purge's severity, make sure you introduce your new acne treatment products slowly into your routine. This is true of other skincare products for most skin conditions! Slow and steady usually wins the race.
Purging is a sign that the product is working and you should continue with the treatment as prescribed. After a few weeks of purging, your skin and acne will have noticeably improved. Breaking out is when your skin is reacting because it is sensitive to something in the new product.
A cystic pimple on your chin? You're probably not purging. Though a skin purge can technically appear as any type of acne, it typically looks like “small, red, tender bumps on the skin, and often [can be accompanied] with the appearance of blackheads or whiteheads,” says Dr. Nazarian.
A purge can last as long as two months, and you should start seeing an improvement by the six-week point, if not sooner. On the other side of a purge is cleaner, clearer skin!
Though some people do report experiencing irritation and breakouts after using the ingredient, niacinamide is unlikely to cause purging. That's because it doesn't affect the skin in a way that usually triggers purging.
Skin purging typically looks like tiny red bumps on the skin that are painful to touch. They are often accompanied by whiteheads or blackheads. It can also cause your skin to become flaky. The flare ups caused by purging have a shorter lifespan than a breakout.
Skin purging is a process that happens when certain skincare ingredients increase skin cell turnover. This encourages shedding of old, dead cells and growth of new, healthy ones. Unfortunately, this process often makes the skin look worse before it looks better.
Retinoids such as Tretinoin, acids such as salicylic, and benzoyl peroxide are just a few of the products that cause purging. These products contain active ingredients that increase the skin cell turnover rate, therefore causing your skin to purge.
These unwanted effects — particularly skin dryness and acne breakouts — are widely referred to as the “tretinoin purge.” While they don't affect everyone, many tretinoin users experience some degree of purge effects during the first several weeks of treatment.
Purging usually lasts between two to four weeks, according to Dr Phillips. “Efficacy is partly determined by the formulation and strength of the product; however, on average, most people will start to see a difference after a month,” he says.
Most niacinamide products also contain a variety of other ingredients. If any of these ingredients increase skin cell turnover then they may be behind any 'purging'. Some ingredients can also be 'comedogenic' which means that they are more likely to clog pores and cause breakouts.
While some niacinamide-containing products start to show initial benefits in two weeks, most results will show in four weeks or more. "You have to remember that it doesn't take two days for spots to form so you can't expect them to be removed in two days either," explains Engelman.
As it's well tolerated by most people, niacinamide can be used twice a day everyday. It works at any time of the year although it comes in particularly handy in winter during cold, dry weather and frequent use of central heating. Use it in the run-up before starting your retinol treatment and alongside it, too.
"Ideally the skin is smooth, supple, and uniform in color," Waldorf said. If your skin feels less bumpy, the size of your pores has been reduced, and you're noticing less marks, acne, and discoloration, your products are likely working.
Some products may create results overnight, some in two weeks, but this four to six week window allows a full skin-cell turnover to take place, which is when you can usually start to see all the benefits from your new skin care products.
To find out just how long you have to use a product before you should start seeing results, we asked dermatologists - who told us that, in general, changes to your skin will take at least a month, but that you should follow a new routine for at least three months to gauge effectiveness.
Be consistent with using the product
No skincare product is magic, so results are never overnight, according to dermatologist Dr. Melanie Palm. "It usually takes 3 to 4 months to evaluate whether a skin-care change is working to improve the overall appearance of the skin," Palm told Well and Good.
When selecting niacinamide products, Dr Ho advises that “a concentration of 4-5% niacinamide is ideal—enough to improve acne and fine wrinkles”. Higher concentrations, like The Ordinary 10% Niacinamide + 1% Zinc, have not yet been proven to exhibit a higher rate of efficacy.
How long does niacinamide take to work on hyperpigmentation? In mild skincare conditions, you'll notice visible results within two weeks. Based on most clinical studies performed on people with stubborn concerns, we can estimate that niacinamide can improve hyperpigmentation in 4-8 weeks.
