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 Great product I’ve been using the Effaclar range for just over a year, I love the Effaclar H cleanser and moisturiser, and also the Duo on my oilier T zone that is prone to blemishes and spots. Thought I would try the Serozinc face toner, and wow I love it! This is a fantastic product. It mattifies your skin, making pores appear smaller, and my skin feels fantastic, so soft. People have asked me what I use on my skin, as I look so much younger than my age! It’s so easy to spritz on, and it lasts for ages. I wish Boots would sell the smaller travel size version. Thank you La Roche Posay for delivering products that work at a good price, and great that Boots often have offers on these products. V happy customer!

Rated 5 out of 5 by from Calming and mattifying I have very oily skin, but because I use a retinol at night I always use a daily moisturiser with SPF and it is not a very mattifying base for my makeup. However, if I spray a very light mist of this toner on after washing my face and before applying my moisturiser it keeps my face mattified and my makeup lasts way longer until the shine comes through. With Serozinc on I can get away with only one touch up after lunch. I use blotting paper and a light dust of powder and I am good to go for the rest of the day. I have also noticed that my redness has significantly reduced, which was an unexpected bonus as I bought this mainly to help with oil control. As I only use a small amount this large can is going to last months. Just spritz on a very light mist and leave to dry by itself. Don’t try and wet your face or it’ll take forever to dry or you’ll have to start blotting it off, which is just a waste of product. You’ll think that tiny amount can’t possibly do much, but it does!

Rated 5 out of 5 by from AMAZING I have never written a review about a product but I felt I had to as I have never been so pleased with a product in my entire life. This was gifted to me from a friend and oh my I have not looked backed since. I am 17 so have suffered from outbreaks for around 4 years now on and off. I have used SO many things to try and get rid of them (benzoyl peroxide) but nothing has worked. I have suffered redness and even when I dont have spots I always have little bumps on my forehead or wherever that would not go away UNTIL NOW. My skin has not been clearer in 4 years and for the first time I am completely confident in not wearing makeup and for the first time ever people are saying how nice my skin looks. I will be purchasing this time and time again. Also it lasts ages!!!! SO simple to use i just spray it on after a shower and thats it. No faults. If i could rate it 10 star I would.

Rated 5 out of 5 by from Brilliant product I use this throughout the day over my make up to combat oiliness and keep new spots at bay. It dries within seconds and leaves no residue over my make up, leaving a perfect matt finish.

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 Clams angry skin Spritz on, if your skin's acting up. The zinc helps calm down most problem areas. I use after cleansing and on top of makeup in the day. A great all round spray. My teenager has a long term borrowing plan for mine.
