Serozinc ($23.99 for 150ml) has been around for a little while but has only just launched in Australia. Like all La Roche products, it has a thermal spring water base plus two active ingredients: zinc sulphate for oil control and and sodium chloride aka table salt which acts an as astringent.
This product is designed for oily, acne-prone or irritated skin. My skin is oily, and while it is prone to break-outs, I wouldn't say it's acne-prone or irritated. Serozinc is meant to "help mattify oily skin, prevent excess shine and tighten the appearance of pores". I did a little research on sodium chloride and found that while it can be used as an astringent, it can also cause breakouts which confused me a little. But I had no other choice than to put it to the test and see what happened.
I like that Serozinc comes in an aerosol, it makes it really easy to add into your routine. I've been using it in the morning as a toner step before moisturising. It's really refreshing and immediately makes your skin feel cool and hydrated, which would be the thermal water at work. After using it for a few weeks, I have noticed that although my breakouts haven't decreased, and my pore size hasn't been reduced at all, my skin is definitely a lot less oily.
I'm on the fence a little about this product. I am impressed with how much less oily my skin is. However, if it doesn't have any effect on my not very acne-prone skin and my average sized pores, I do wonder how much it would do for someone who actually does have problem skin.
