A natural sunscreen to wear everyday, without causing chemical harm to yourself, is a must under the UV rays of the sun. Natural sunscreens should be comfortable to wear without feeling heavy and greasy and become part of your everyday ritual.
The two main causes of skin ageing is our natural genetic progression and also photodamage caused by the sun. It makes sense then to protect your skin from the harmful sun rays by wearing suitable clothing (shirts and hats) and wearing an appropriate sunscreen. A hard hitting fact is that 90% of our skins ageing comes from UV rays.
Why do we need to use a sunscreen
- Protection from ultra violet rays
- Prevents premature ageing
- Prevents skin cancers
- Prevents sun and age spots
- Prevents thickened leathery looking skin
What does SPF mean?
SPF means sun protecton factor and is a measure of how well the sunscreen deflects UVB rays and how much protection it provides. In a nutshell a sunscreen with a higher SPF doesn't give you more protection, just a longer period of time that the ingredients will absorb the UV rays. So a sunscreen with an SPF 50 is not necessarily twice as effective as a SPF 30 sunscreen product.
The Australian Cancer Council states that a sunscreen should be reapplied every two hours.
Different types of sunscreen
Physical sunscreens will reflect UVA and UVB rays and because of this keep the skin cooler. These sunscreens use ingredients such as zinc oxide and titanium dioxide. As this type of sunscreen sits on the skin it has more of a tendency to move or wash away in the case of water (swimming, sweating etc) and for confident protection the need to reapply each two hours is important and choosing one with a higher percentage of zinc.
A chemical sunscreen is a UV absorber into the skin and is designed to absorb and neutralise UVA and UVB rays. A heavy weight moisturiser should not be used under this type of sunscreen.
Often sunscreens will contain fragrances which will irritate some skins. Some sunscreens will contain vitamin E which will nourish your skin as well.
Your sunscreen is put on last during the day and, of course, not needed at night. Reapply as necessary according to the sunscreen directions for correct coverage.
