I have been using La Roche-Posay Serozinc for two months and I am SO glad I bought this product. I suffer with severe cystic acne and often travel abroad where the climate is much more humid and the weather does not help my skin at all, however I have found by using Serozinc after cleansing my face, it helps to keep my skin fresh and has reduced my acne break outs. It is light weight and sinks into my skin immediately, leaving my skin feeling less oily and greasy. I LOVE this product!

Rated 5 out of 5 by from Really works! I've been using this spray for about 4-5 months now (only on my second bottle) and have really noticed a difference in my skin. I rarely ever get any spots anymore and my skin seems a lot calmer and less red. I used to have tiny bump-like spots (not red, just bumpy), all over my forehead for as long as I can remember and since using this spray, they have all completely disappeared! I also spray this onto my back as I suffer from spots there too and I have definitely noticed a reduction. This is now a staple in my skincare routine! (I spray it lightly over my face and chest after removing my makeup and on my back after a shower in case you were wondering!)

Rated 5 out of 5 by from Bye bye spots! From someone who has suffered with habitual acne for the past 10 years, I have tried a lot of products to curb it. Other La Roche Posay products from this range haven't worked for me so I took a chance on this and it's now a HOLY GRAIL PRODUCT I've only had this product a week but after just the first use, the results were dramatic. My skin was smoother in texture and the small annoying spots around my nose that I had been battling with for months have disappeared. I've had two new spots since using this product and the product has seemed to significantly reduce them so that I can barely see them anymore. I highly recommend this to anyone who is still searching for something that will tackle spots, at the price point, it's really worth a go.

Rated 5 out of 5 by from FANTASIC product I have combination skin and am really prone to breakouts, so started a new skin regime last year prior to my wedding.. it included this alongside some great products from The Ordinary. My skin had never looked better - clear, fresh and healthy. This ran out after a few months of using twice a day, which is pretty good. I didnt repurchase straight away as I thought it was more likely to be the (3) other products making a real difference. But no! They had helped, but some blemishes returned. I rebought this three days ago and they’ve already all gone! Pores are smaller and t-zone less oily with dry areas also looking better. truly fantastic product. It may not work for everyone, but it’s wonderful for me!

Rated 5 out of 5 by from Holy Grail I received this as a birthday present and it's fantastic! I have always struggled with blemishes and redness around my chin and the sides of my nose; I have tried many products to get rid of them but they never work until I came across this spray. I use this as part of my skincare routine when taking off my make up. I apply this after cleansing and toning; I let it sit on my face for about a minute and then I gently pat/press the excess into my skin. My skin feels really clean after using this. I would recommend it to anyone with acne or annoying spots/redness.

Rated 5 out of 5 by from Cleared hormonal acne alongside effaclar duo I was going round the bend getting horribly huge massive hormonal cysts every month that then dried to leave huge horrible dark marks that themselves take months to clear. I felt like I had tried everything. Sunday Riley's luna oil (which has retinol) started reducing the severity of the cysts (they were smaller, did hang around as long) but since adding La Roche-Posay's effaclar duo morning and night and the serrozinc spray I've not had a spot! And at such a reasonable price compared to other brands. Massive confidence boost. Just need the old marks to disappear and I'll be over the moon :)

Rated 5 out of 5 by from Love it!! I use this product morning and night, its quick and easy to use and dry quickly which allows me to put my moisturiser on straight away. The difference in my skin since using this product is fantastic! I have a really oily t-zone and by the afternoon my skin is really shiny and I always have to touch up my make-up to reduce the shine, but since using this product my face has been practically shine free. I have also noticed that my blemishes are not as red and my pores are less noticeable. I would recommend this product as it's great value for money, you only need a little spray to cover your whole face so this would last months.

Rated 4 out of 5 by from Great product annoying spray I really like this product its very calming on the skin and good value for money. The thing i dont like is the actual sray itself it starts off fine and a thin mist however after about half way down the bottle it becomes more thick droplets and not a mist anymore ans the closer you get to the bottom the worse it gets. I've bought many bottles of this and all the same because of that I don't buy it any more but stilll a good product

Rated 4 out of 5 by from Great Product. Helped my oily skin! I've always had oily skin but never suffered from spots or acne so was quite interested to try this. I don't have a face cleansing routine and tend to go to bed with my make up on. I liked how easy this was to use. Didn't really have a scent and felt light on the skin. I have found that it has helped my make up stay put throughout the day as it generally tends to slide off before the end of the day. I haven't noticed a change in the look or appearance of my skin but the oilyness has definitely improved. On the whole I think this is a good product, my skin hasnt been left feeling dry or tight like some products for oily skin can do. would definitely recommend.
