Sunscreen (Physical vs. Chemical)
I bought Dr. Hauschka sunscreen cream SPF20, which claim to be a physical sun block. (As I know that sun block has two types, physical and chemical). As you know that I try to avoid as many products that contains chemical as I possibly can. Dr. Hauschka sunscreen cream claims to be an organic and biodegradable sunscreen. However, a physical sun block requires one to use make-up remover to clean it off the skin. This is the only disadvantage at the moment. Yet I have never used this sunscreen before, so I do not know if this one is greasy or not.
The one I have used before is Shiseido SPF 30 and the one I’m using now is Shiseido SPF 50, both belong to the combination of physical and chemical sun block group. In other words, they contain both physical and chemical sunscreen properties. They also require one to use make-up remover to clean off. Shiseido sunscreen is very popular because when you are under the sun with this sunscreen, your skin rarely gets darker. I guess the reason is because the zinc oxide in it, which is a powder-like form, that physically blocks the UVA/UVB etc. If this is true, then I guess the pure physical sun block can also do this job well. The chemical part of the sunscreen is mainly to protect the skin from burning.
Yet, shiseido does have one sunscreen that is a physical sunscreen. This is one of the 3 physical sunscreen I know (other than Dr. Hauschka), and it is Shiseido SPF 24 (I’m not sure, forgot but it is one of shiseido’s product). The other one is DDF Organic sun block SPF30. This is another one that I am very interested in and will try out in the near future.
