I recently started using the following oil blend on my face and my rosacea has improved dramatically, so I thought I'd share:
50ml Castor Oil
50ml Rosehip Oil
50ml Black Seed Oil
15 drops Frankincense Essential Oil
Put a small amount on at night before bed.
I've tried everything over the last few years, including Dermatica and Skin+Me. They worked at first but any improvements seemed to stall, and they are both so expensive (and Dermatica always have issues with delayed deliveries).
The oil has made a huge difference in the 4 months I've been using it, and I can now go without makeup again!
