Why Is My Skin Suddenly Breaking Out?

Quick Insights

• Breakouts have outside triggers and inside ones. Like your routine and products, or hormones and your gut as examples.
• Going too far with your routine can mean stripping your barrier or over-nourishing it. Both can cause breakouts.
• If the cause is internal, skincare can help manage breakouts, but it can’t stop them from appearing now and then. That’s why you need to tackle the internal cause for them to really go away.

I had breakouts around 19.
I had no idea what caused them.
That’s when I discovered skincare.
I got so intrigued by products that can improve your skin that I became obsessed.
That’s why I chose to become an aesthetician and learn all about the skin.

To this day, even as a licensed aesthetician, I don’t always know why a breakout pops up on my own skin.
But that’s okay because it’s difficult to figure that out because there could be so many reasons.
So if you’re asking why your skin is suddenly breaking out, I get the confusion (and the frustration).

Not all the clients I worked with had acne.
But the ones who did often asked: “What is causing this?”
If it were that simple, no one would have acne.
Yet lots of young adult women still do.

Why is my skin suddenly breaking out?

So there are many possible explanations.

• Outside factors: your routine and your products.
• Inside factors: hormones, your gut, and more.

And the chart on this page shows outside factors only!

Did you change products recently?

Yes, this trigger happens a lot.
Many of the breakouts I saw in clients came from using the wrong products for their skin.
A drying cleanser or a moisturizer that’s too rich can be enough to give you a few new pimples.

People know the skin barrier matters now.
But some go too far with their routine.

• Stripped skin barrier: too much exfoliating or scrubbing.
• Over-nourished skin barrier: layering rich creams your skin doesn’t need.

Both can cause breakouts.
A thick moisturizer doesn’t damage your barrier (it over-nourishes it).

Little tip: a harsh routine can also make your skin act differently from your real skin type. More on that in is your routine misleading you.

And there’s more on routines in this piece on skincare routine mistakes, and on mixing actives in can I use these together.

What if it isn’t your routine or your products?

Then the trigger may be internal.
A hormonal IUD, the pill, or a hormone shift can trigger or worsen acne.
For that, work with a doctor or dermatologist and get your hormones tested.
Recent research has confirmed a gut-skin link. This review walks through it.
So if you have gut issues, that might be where your skin issues come from.
For some people, it really is a thing.
If you want help on that side, talk to a nutritionist about gut health.

If the cause is internal, skincare can help manage breakouts, but it can’t stop them from appearing now and then. That’s why you need to tackle the internal cause for them to really go away.

Could it be something touching your face?

It’s worth checking, but honestly, it’s often not the biggest factor.
What I notice much more is picking at your skin having an impact. When you touch your face all the time and start picking, you can actually create your own breakouts and make them much worse.
Pillowcases and brushes usually play a smaller role (washing them is still worth a try).
Hair products can slide onto your hairline and cheeks (so if your breakouts sit around your hairline, definitely check this).

What should I do first?

First of all, don’t panic-buy.
I’ve heard this story more than once: people throw out their entire routine and buy a new one.
Please don’t be one of them!
So first simplify your routine, and your wallet will definitely thank you (and your skin probably too)!

How I’d do it:

• Pause the newest product.
• Keep a gentle cleanser, a moisturizer, and SPF.
• Change one thing at a time, and give it a few weeks.

If your skin feels calmer, bring one product back, but very slowly.
If nothing changes and you’ve tried a lot, maybe see a professional for advice instead of buying another serum.

When to see a doctor or dermatologist

See a doctor or dermatologist for painful, deep, or cystic spots.
Also for marks or scarring, a sudden severe change, signs of infection, or anything that worries you.
Same if you’re pregnant or on medication.
Same if you think hormones or your gut are involved.

FAQ

Q: Why am I breaking out all of a sudden? A: It can be outside factors, like your routine and your products, or inside factors, like hormones or your gut. So starting with your routine is the easiest place to begin.

Q: Should I stop all my skincare when I break out? A: It depends. If your skin barrier is stripped or over-nourished, simplifying helps. If your skin is producing too much or irregular sebum, a targeted serum with the right actives, or a retinoid, can help.

Q: Can a new product cause breakouts? A: Yes. This trigger happens a lot. A drying cleanser or a moisturizer that’s too rich can be enough to give you a few new pimples.

Q: What if my routine isn’t the cause? A: If the cause is internal, like hormones or your gut, skincare can help manage breakouts, but it can’t stop them from appearing now and then. That’s why you need to tackle the internal cause for them to really go away. Work with a doctor or dermatologist.

Q: When should I see a dermatologist about breakouts? A: See a doctor or dermatologist for painful, deep, or cystic spots, marks or scarring, a sudden severe change, signs of infection, or anything that worries you.
