As the days gets warmer and we spend more time outdoors one may ask: should we use an SPF cream or not?
And if yes, what SPF number should we use?
The answer to those questions may not be that straight forward. We read on all beauty magazines that we should use a high SPF cream every time we go out.
While I am a strong advocate of using an SPF 30 or 50 on the face, neck, ears and back of hands to prevent wrinkles and “liver spots” , I am a bit more forgiving when I talk about the body exposure to sunshine. You may wonder why !
We all heard how damaging are the ultra-violet (UV) rays, but not many of us knows that :
•UV are healing and desinfecting, thus helping acne
•UV are involved in the making of Vitamin D3, which makes the bones stronger.
Let’s see how is UV produces Vitamin D3: on a sunny day: as the UV baths the skin, in the presence of cholesterol, the skin makes vitamin D3. That’s why is very important to get at least 20 minutes of unprotected sun exposure a day, before 10am and after 4 pm.
I will talk about the sun damage in another blog.
