3. Heat
Something that you might notice, is that your rosacea becomes worse at certain times. While you might have a constant ‘underlying’ rosacea, it’s common for it to get worse during specific set periods, known as either breakouts or flushes.
There are lots of reasons you can get a ‘flush’, but one of the most common ones is heat. You might notice that in hot weather, specific patches around your face appear red – this is the rosacea.
This may lend some credence to the role of those tiny blood vessels. Our body’s thermal regulation works to heat us up and cool us down accordingly, by pushing the blood vessels to the surface of the skin nearer the fresh air and then burying them deep to warm us back up – depending on the ambient temperature.
