18 Apr Sun & Skin
One of the most frequent questions I get asked is in regards to sun protection.
There is a lot of misleading information, about the sun and sun protection creams. So, this month is about our skin and the importance of protecting it. With the harsh Sun that we have here in Australia it is important that we realise the damage that it can do to our skin. So lets make it simple and easy to understand starting from the basics.
The sun radiates Ultraviolet radiation, there are 3 types UVA, UVB and UVC. Whilst UVC does not penetrate the ozone, UVA and UVB do. Both of these UV types are associated with ageing, pigmentation, burning, and causing skin cancers.
Whist some skin types can seem to tolerate the sun better then others, the effects on the cells are the same. When we expose our skin to the sun for a long period of time unprotected, it causes inflammation within the skin. The cells respond by going into over production mode. One of these cells is the Melanocyte, this is what produces pigment and ultimately darkens/tans our skin. The over production is the skins way of attempting to defend itself.
The high concern about UV radiation is that it is an ionising radiation, which triggers mutation of the DNA in our cells and begins the process of cancerous cell production.
It is important to remember that even though it may seem like an overcast day, this doesn’t mean there is a low reading of UV. Check the UV readings for the day, this will make you aware of the times that the UV is at it’s highest.
Whilst it is important for us to get some sun for the production of Vitamin D, it doesn’t mean we need to spend hours out in the sun especially unprotected.
There are 2 main types of sun protection
What’s the difference you ask? The answer is pretty much in the name. A Sun block will block, and reflect both UVA & UVB radiation. Not allowing any ultraviolet radiation to get through.
A Sunscreen does just that, screens/filters what comes through. The ingredients absorb UVA and UVB radiation before they reach and damage the skin cells.
The ingredients in both of these types of sun protection differ. A number of products contain zinc oxide & titanium dioxide as main ingredients, these are normally found in sun blocks. Chemicals can also be found in many sunscreens or sun blocks and can also been known to cause irritation to the skin. A number of people have told me that they have experienced some sort of allergic reaction to some sun protection creams. If this does happen it doesn’t mean that you cant wear sun protection, it just means you will need to find the right one for you.
Remember that we aren’t born with freckles, think of how clear and beautiful a babies skin looks. Freckles are caused by the sun and can be reduced by applying the correct sun protection.
At Divine Skin Clinic we stock a number of Sunscreens & Sun blocks, there is something for everyone. Next time you are in, feel free to speak with our therapist about trying some. If you have any questions about sun protection, please feel free to email back or book in for a consultation with myself, Janet.
I hope that this information has given you a little insight on the effects of Sun on our skin, and the importance of protecting it.
I look forward to sharing more information and shedding some light on the beauty/dermal industry. If there is something that you would like to know more information about, please send myself an email
***An interesting fact to note is whilst UVB cannot penetrate through glass, it has been proven that 60% of UVA can pass through a car window. This could be why we see more pigment on one side of the face more then the other or even more pigmented spots showing up on hands due to resting your hands on the steering wheel.
