Oil your skin inside and out
Dry or itchy skin can by annoying, embarrassing, irritating and difficult to treat. It's really important to keep your skin hydrated, both inside and outside. Excessive showering washes away the body's natural oils, you will need to moisturise regularly to keep the skin hydrated. Stress is a factor, certainly for me; my skin will always flare up when I am stressed. B Vitamins are helpful during these times.
Food can have either a positive or negative effect on your skin. Any food that you are intolerant, or foods that create inflammation in the body will also cause a problem; inflammatory foods include dairy, red meat, and sugar. Increase foods that reduce inflammation, foods rich in omega 3 oils; nuts, seeds, oily fish, and avocado, olive oil, coconut oil, and rapeseed oil.
You will need to drink up to 1 1/2 litres of water. Reduce food that excretes minerals from the body, in particular coffee. If your skin is very dry you might find that warm food will keep you hydrated better than a diet that is made of up of cold food. Many people find coconut water better for rehydration than plain water.
Read the labels on your body care products. Choose ones with natural ingredients. I really like Dr. Bronner liquid soap; you can use it on your face, hair, and body. It contains natural oils, and no harsh chemicals, it won't dry out your skin. If your skin is itchy try Salcura creams, and sprays they can help dryness, and reduce itchiness associated with eczema, dermatitis, and dry skin conditions. Nia, Just Balm, is a really good moisturiser, with all natural ingredients; it can be used on any part of the body, even on dry lips.
So to help your skin; look at what you put into your body, and what products you use on the outside. Both are crucially and equally important. I don't always follow my own advice and as a result I often get flare ups. Solving problems is easier said than done. But doing nothing won't help either!
