As you can see, the greatest climate change during the year comes between the summer and winter months. In places like Kahului, Maui, the decline in temperature is as much as 10 degrees Fahrenheitâdropping from an average temp of 79.2 in August to a chilly (for Hawaii) 68.9 average in January.
Vitamin C, in the form of L-ascorbic acid, has anti-inflammatory effects that act specifically on the blood vessels which can reduce redness and irritation of the skin. Vitamin C can also control the release of histamine, a chemical that dilates the blood vessels during an allergic reaction. Because it can reduce redness and prevent excess blood flow to the skin, vitamin C may be beneficial in controlling the swelling and redness associated with rosacea.
No direct cause has been found for rosacea as yet but it could be due to stress, poor nutrition, temperature extremes, hot baths, spicy foods, drugs that dilate blood vessels and so on. Studies have also been carried out to find out the connection between Rosacea and Vitamin D deficiency. However, direct exposure to sunlight can also trigger off an attack, it is essential to maintain the adequate levels of Vitamin D and medical advice should be sought in this case. As the skin condition called Rosacea progresses, one often finds small pus filled pimples appearing on the face.
