Anything that makes your skin cells turn over faster can cause skin purging, so generally those with exfoliating benefits, such as retinoids (Vitamin A), Vitamin C (a very gentle acid that can slough off dead superficial skin) and hydroxy acids (glycolic acid, malic acid and salicylic acid).
Retinoids, vitamin C, AHAs and BHAs (glycolic, malic, lactic, and salicylic acid) can also activate the skin's purging. Retinoids are the major ingredient that can cause Skin purging. Retinol is found in most of acne skin care products, is an active ingredient that is known to cause a skin purge.
The purging process is working with the skin's cycle and is a phase that should clear up within 4-6 weeks of starting the new routine - anything longer could be more of a reaction.
Since antioxidants, such as vitamin C, neutralize ROS, they may inhibit these protective effects and could cause an increase in acne-causing bacteria. Overall, though, there is not enough evidence to support the claims that vitamin C serums can cause acne.
So if you used a vitamin C serum and it gave you acne, redness or any other skin issue, it is because the serum took away your body's ability to fight off bacteria, and weakened it, inviting pathogens to infect your skin.
A sulfate-free cleanser, a skin calming moisturiser and a physical sunscreen during the day should treat the problem soon and take your skin back to its healthy and clear state. Also, during this time continue the product that's making your skin purge, don't worry it won't get worse.
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.
The purging of the skin starts after a few days of using a new product. In a breakout, the appearance of the acne and blackheads can be concentrated on any area of the face. Purging appears uniformly all over the face.
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.
How long does a purge last? The good news is a purge typically passes more quickly than a traditional breakout. The reason being, your skin is already beginning to turn over -- a process that generally takes 28 days.
No, vitamin C serums cannot cause acne. One of the main arguments leveled against vitamin C is that it acts as a pro-oxidant. This means that instead of neutralizing free radicals, it will act as a free radical itself and begin to damage skin cells. This kind of free radical is called a reactive oxygen species (ROS).
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.
When introducing a new skincare product into your routine, you can sometimes experience an adverse reaction like an increase in breakouts or dry, flaky skin. While this may seem like you should stop using a new product, it may actually be a sign that it's working. This process is known as skin purging.
Many have questioned whether skin purging is real. It may seem contradictory that continuing to use a product through breakouts and holding on through some serious bad skin days can result in your complexion eventually clearing. But purging is absolutely real—especially if you have acne-prone skin to begin with.
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.
