Purging happens when your skin is adjusting to a new face oil or skincare new product, and persevering with the product will eventually make your skin better – in fact, the sudden crop of pimples means that it’s working as intended.


A regular breakout is when your skin is reacting because it’s sensitive to something in the product. It could be clogging your pores, or causing an allergy, or just plain old irritation. Continuing with the product will just make the situation worse.


If your skin is purging, you need to keep going.

If your skin is reacting with a breakout, you need to stop using the product.


How do you tell the difference?


WHAT CAUSES PURGING? To understand the difference between purging and plain old breakouts, we need to understand how they happen.


HOW A PIMPLE FORMS Firstly, we need to look at how a pimple forms. A pore becomes clogged – usually by dead skin cells that don’t detach and get to the surface properly – and forms what’s called a microcomedone. Microcomedones aren’t visible at the surface of the skin. Sometimes they’ll develop into a whitehead, blackhead, pimple or full-blown cyst; sometimes they’ll go away on their own without you noticing. It can take up to 8 weeks for a microcomedone to surface.


HOW PURGING HAPPENS Here’s how purging can actually work – if a product speeds up skin turnover (the rate at which skin cells are shed and replaced), then the entire cycle will be accelerated and microcomedones will turn into whiteheads/blackheads/pimples/cysts more quickly, so you’ll suddenly see a rush of blemishes rearing their ugly heads.


If the product is irritating (which most skin turnover-accelerating products are), some microcomedones that weren’t going to show up might join the party too, since inflammation is one of the factors causing acne. 


However, these microcomedones were in the skin before you started the new product, not new blockages caused by the product. Now, remember how the microcomedone started as dead skin cells that didn’t detach and get to the surface properly? Products that increase skin turnover target this exact process to treat acne! So as the product starts to work, less microcomedones should form, and after the initial angry-volcano stage your skin should become clearer than when you started the product.




On the other hand, a reaction will occur when the product is either causing new clogged pores, or increasing irritation without an improvement in how your skin is functioning because you’re sensitive to it. New clogged pores means more blemishes overall, while irritation means inflammation, which means a larger proportion of your microcomedones are flaring up.


There’s a small chance that your skin will get used to the product over time, but most of the time you’ll just cause further damage and it’s time to find a better product.


Unless there’s something increasing skin turnover in the natural skincare product (e.g. fruit acids, which contain AHAs), the more likely explanation is that there’s an irritating ingredient giving your skin grief.




There are a few things to consider to work out if it’s purging or a reactive breakout, and therefore whether you should dump your product or persevere. A lot of the time it can be difficult to tell which it is, but hopefully these guidelines can help you narrow it down.




Products containing active ingredients that increase skin turnover can cause purging. Purging is a well-documented response to tretinoin, for example, although you won’t find the term “purging” used in the scientific journals.


Active ingredients and treatments that increase skin turnover include:


  • hydroxy acids (glycolic, lactic, malic, mandelic, salicylic, lactobionic acids; gluconolactone; “fruit acids”)

  • retinoids (retinol, tretinoin, adapalene, tazarotene, isotretinoin, retinyl palmitate)

  • benzoyl peroxide

  • chemical peels, lasers, microdermabrasion

  • other exfoliants (scrubs, brushes, enzyme exfoliants)

Most other products, like moisturisers and cleansers without these actives, won’t be able to cause purging and you should switch to a different product.




If it’s purging, it should only make pre-existing microcomedones come to the surface faster, so if you’re breaking out in places where you don’t normally experience breakouts, it’s likely that the product is wrong for you. However, if it’s an irritating product, it could be making the type of acne you’re experiencing worse. For example, an area where you used to have clogged bumps and whiteheads could start developing full-blown pimples thanks to the extra inflammation.





Purging should only last for about a month, since that’s the length of time it take for your skin to completely renew itself. If your skin isn’t getting better after around 6-8 weeks with the new product, ditch it.




If you’re about to start a new product with an ingredient that can cause purging and you want to limit the severity of a purge, there’s some evidence that introducing the new product slowly can help. This means starting at a lower concentration, starting at a smaller amount, using it less frequently, or washing it off after a few minutes before gradually increasing to the recommended usage.


Helping your skin function at its best will also reduce irritation and speed recovery: ensuring that your skin stays hydrated, using a gentle cleansing routine and using anti-irritant or antiinflammatory products and protecting your skin from the sun.
