    Helping to control my oily skin, redness & large pores!

    I used to use this in the morning and wasn't a fan as it didn't sit well under make up. I now use after cleansing in the evening, before applying the azelaic acid. I suffer with large pores, texture and redness from rosacea and have found that in the last month sticking to a consistent skincare routine and using an LED mask alongside it I've begun noticing an improvement in my rosacea for the first time in years!

    Redness and breakout saviour.

    This has definitely helped reduce my hormonal breakouts. The picture was taken during a time they'd normally be noticeable, but no, instead I have nice, mostly clear skin.
