Sensitive skin is caused by a deficiency in pH balance. This can cause skin to become very easily irritated and it can begin to thin. The integrity of capillary walls becomes compromised and this can lead to problems with blood-flow to your face and cheeks as skin can become irritated and uncomfortable.

Harsh weathers such as extreme cold and extreme heat can cause the skin to dry out. This contributes to the thinning of skin and can even lead to a condition called Couperose whereby capillaries in the face dilate to allow blood to flow to the cheeks, the capillary walls are not strong enough to return to their normal state and so therefore stay dilated. This gives a red complexion to the skin and capillaries become visible.

In order to prevent this, there are many things you can do to protect yourself from harsh weathers. The most simple change is to your clothes. Wearing scarves which cover your cheeks in extreme wind can be very beneficial. Furthermore, wearing light clothing and light hats in extreme heat can allow the skin to breathe better.

If the skin has been exposed to lots of heat, the brain will detect some dehydration. This causes the brain to send a signal to the skin's sebaceous glands to produce sebum which is the body's natural, oily substance used to keep the skin moisturised and hydrated. After heat exposure, the skin can become clogged with sweat and oil and pores can become blocked preventing the skin from breathing properly. This can cause spots and blackheads. An excellent way to combat this is to try SkinAu's Sensitive Skin Gentle Cleansing Milk which is a non-irritating product to nourish and thoroughly clean skin to allow it to return to its natural pH levels.

Consistent exposure to extreme cold wind or heat from the sun can take its toll on the skin and so keeping up with a repairing and protective skin regime is vital so that your skin does not develop any problems and can stay healthy to protect your body.
