Skin Experts Are Excited About This Acne-Fighting Ingredient, So We Are Too

In recent years, the rise in cases of adult acne has been likened to an epidemic. More and more adults (mostly thanks to stress wreaking havoc with hormones) are having to deal with teenage skin long after blowing the candles out on that 19th birthday cake. Whether you’ve tried tweaking your diet (have you tried giving up dairy yet?) or switching up your skincare routine, it’s a really tricky skin issue to fix because the causes and fixes vary so wildly from person to person. In short, when it comes to acne, we’re still after the miracle cure.

So when we heard that two highly respected dermatologists mentioned the same spot-fighting ingredient within weeks of each other, our ears pricked up. Especially because it’s not one we’ve heard batted about before. Besides, who could forget a catchy name like spironolactone?

What is spironolactone?

One of the reasons this ingredient has been lying low is because it can’t be applied topically. In fact, it’s an oral form of medication that was initially used to treat mild blood pressure and water retention. However, women with combination skin taking the drug for those aforementioned reasons soon found that one of the side effects was better skin—in particular, fewer spots and breakouts.

It’s been dished out stateside for the past decade to treat adult acne, but it’s only really hitting the UK now. Nick Lowe, MD, consultant dermatologist and clinical professor, practices out of both countries and says this is because prescribing it for acne is essentially “off-label,” meaning it wasn’t designed to treat spots, so it doesn’t sit neatly under that category.

That being said, dermatologists, gynaecologists and endocrinologists have been using it for women suffering from PCOS for a while. “It’s not actually licensed for treating acne in absence of the full syndrome, but consultant dermatologists can prescribe the drug on an off-label basis for women who have a hormonal pattern to their spots and whose acne hasn’t responded to first-line therapies such as prescription creams, antibiotics and even Roaccutane.” explains Justine Kluk, MD, dermatologist and acne specialist.

So when women experiencing spots get wind of a treatment that works without any irritation to the skin or other nasty side effects (some lightheadedness can occur if you have low blood pressure), they might be quick to jump in. Which is why it’s now starting to gain traction as a treatment for women who have hormonal acne.


How does this dream ingredient work?

It’s the impact spironolactone has on the hormones that give it its superpowers. That’s because it blocks the effect that androgens (hormones like testosterone) have on the body. Those effects include increased sebum production and bacterial growth. Once you stop those, the acne glands and hair follicles won’t get overloaded, thus reducing the likeliness of pimples.

The trouble is that androgens are notoriously tricky to target, which is why spironolactone doesn’t perform very well as a topical treatment. “Studies show it’s the same concept as Roaccutane in that it works when ingested via the mouth, but not when applied as a gel,” says Lowe.

The good news? The more people are talking about it and the more studies proving it’s worth on complexion clearing, the more likely it will start to become a go-to for dermatologists and doctors—especially when cases of adult acne are on the up.

Is there anyone who shouldn't take it?

Because the drug tampers with hormone levels and testosterone, it’s recommended for use by women only (it could potentially cause men to suffer from gynecomastia, enlarged breast tissue and tenderness). It also can’t be prescribed for those who are trying to get pregnant, so bear this in mind if you’re planning to conceive any time soon.

How long does it take to work?

Like most skincare products, topical or oral, you have to give it time to work. Kluk says it takes around three months to see results. The good thing is that there’s no time limit to how long you can take the drug, unlike the antibiotics that are often be prescribed for acne.

Having said that, some dermatologists advise taking antibiotics at the same time, including Lowe. “If someone keeps coming back for acne because other treatments aren’t working, I’ll prescribe a low-dose antibiotic along with spironolactone, but that will soon be withdrawn and then they can remain on the spironolactone for long-term periods,” he adds. If you do find yourself on antibiotics, be sure to bolster your gut bacteria (it can be adversely affected by antibiotics) with a probiotic like Symprove.

Described by Lowe as an “old medicine that’s been rediscovered for new uses,” if you’ve tried everything from AHAs to giving up dairy and regular facials to prevent pustules, then this could be the ingestible answer you’ve been looking for.
