This stuff is brilliant! I was prescribed this by my GP as one of the last things we could try to use to clear my stubborn cystic acne. Although it's worth noting that I was also prescribed antibiotics alongside, the benefits from this are far more noticeable. Not only has my acne cleared, but my scars are visibly lighter and I have far less visible texture. It has more of a gel constantly, sinks in well and isn't uncomfortable. So far, I've never experienced any irritation or redness from using this- I sort of "sandwich" it in between two layers of moisture to act as a buffer. Absolutely love this, would recommend (remember SPF!)
