I was pretty disappointed with this product as it gets great reviews but I found it ineffective. I have oily, acne prone skin and found this did not do anything for any breakouts I had on my face; in fact, I think some areas would look more red and irritated after using this in conjunction with the oxygenating moisturiser. I would save my money for things that are more effective for acne prone skin (I.e, acids, retinol, vitamin c)

Prior to using this I used to get a huge, unsightly boil on my chin about twice a year. Since I've used this I haven't got one pimple, not talk about a boil. I only use it in the morning. A bottle lasts me about three months. Wish it was cheaper.

If you are acne-prone to a degree where every skincare product (be it moisturiser, serum or even a mist) makes you break out, this is the perfect one-step serum-and-moisturiser, which will actually heal the acne (especially broken lesions) and not cause further breakouts. It is also the ideal pre-makeup skincare; it makes my makeup look better. I am on my third bottle and will definitely repurchase. It is expensive, yes, but my skin is thanking me for it.

I'm so disappointed at this product! I really don't understand the hype. I tend to spend a lot of money on skincare and this is one of the occasions that it wasn't worth it! I have a specific skincare routine of 10 steps, so I don't just use a serum and expect miracles. However, there are products that after using them for a month you can tell whether they benefit your skin or not. That being said, this particular serum did nothing for me and I will not spend 90 pounds on buying it again.

Nothing (apart from antibiotics) cleared my acne like this little miracle worker. It's not cheap but it's definitely worth every penny, I will never be without it!
