la roche posay serozinc review

I love it when skincare is stripped bare.

Take away all the unnecessary layers and extra frills and leave in only the stuff that works. You know, the active ingredients that do the heavy lifting.

Less chance of irritations that way. And wading through the label becomes a breeze.

La Roche Posay Serozinc is stripped like that. All is left with is water, zinc sulfate and salt (yes, Sodium Chloride sounds posher, but it is still table salt).

I know what you’re thinking. Why should you splurge on a tube of water, salt and zinc?

Because zinc is a miracle cure for acne. Or so they say. But is that true?

What’s In La Roche Posay Serozinc?


Zinc is a metal ion naturally found in meat, nuts, whole grains and legumes. It’s an essential nutrient your body needs to work properly. For example, wounds can’t heal without it.

In anti-acne products, Zinc is used for its oil-regulatio properties. It reduces the production of hormones responsible for excessive oil production. Less oil = fewer breakouts.

The catch? Zinc comes in many forms. You’ve guessed it, some are more effective than others. La Roche Posay Serozinc uses Zinc Sulphate.

Zinc Sulphate helps treat acne – when taken orally. When typically applied to the skin, it doesn’t work any better than the placebo. But it’s more irritating.

What a bummer!

Performance & Personal Opinion

La Roche Posay Serozinc sort of failed its theory test. The science isn’t there. But, what about its practice test?

I’ve been using it for a few weeks even though my skin isn’t particularly oily at the moment. Just a bit shiny on my t-zone. That’s where I also get the occasional bout of blackheads.

Even though I’ve been spraying Serozinc on my face every morning, I can’t say it did anything for me. It felt refreshing on the skin, which is something I’d definitely appreciate a lot in summer. Not so much now, you know? But, apart from that, I can’t report any other benefits. 🙁

Even so, I don’t think it’s totally useless. Lots of people are using it with good results. After all, zinc does help with acne, so I tend to believe zinc sulfate helps acne a little bit too.

But there are much better treatments out there. If you switch Serozinc for a treatment with salicylic acid, benzoyl peroxide or sulfur, you’ll see much better results, and much faster too.

Who Is This For?

I can’t recommend this to anyone.

Who Is This NOT For?

Again, I don’t recommend it to anyone. There are more effective treatments for acne out there.


A blue and white spray bottle. Simple and practical.

Does La Roche Posay Serozinc Live Up To Its Claims?

A facial mist toner featuring Zinc Sulphate, specifically designed to target key signs of oily, blemish-prone skin.It’s a mist toner designed for this, but it doesn’t do anything for your skin.
