Hi Debbie,

I'm glad you like the two products sent to you this time and did not have any
untoward reactions. Yes, the powder is a physical sunblock. The main
ingredient, titanium dioxide, an FDA-approved sunscreen ingredient, is an inert
substance which gives "hide" to many products. It is used in oral medications
(pills) to give them a white opacity(color). It is also used in makeup
foundations and even in paints to give them hide.Physical sunscreens act much
like "an umbrella on the face" and they block UVA, UVB as well as visible
light. The other ingredients in the powder are also physical sunscreens but
they are not FDA approved as sunscreens officially. I do not expect the powder
to cause problem because it is such a simple formulation and has no
preservative or irritants. Somewhat similar products are the non-chemical type
of sunscreens.These products also contain physical sunscreens such as microfine
titanium dioxide or microfine zinc oxide in their formulation. However, they
may contain preservatives, emulsifiers etc. because of the water content. Water
attract bacteria and molds; therefore, formulations containing water require
preservatives. Physical sunscreens are particularly useful for individuals who
are either allergic or irritated by ordinary sunscreens which contain active
chemical sunscreens such as cinnamate, oxybenzone, padimate, avobenzone and the
like.

Aside from the Concealing Loose Powder which has a neutral beige tone, we carry
a Bronzing Loose Powder which gives one a natural-looking tan. This can be
applied directly on the face or added to a moisturizer to give it a tint.  This
is a long message but I hope it helps educate re sunscreens.

Hi everyone...Thanks Linda for the response re: the new products sent out-I
just assumed everyone was gettin' the same things and I shouldn't have! I
hadn't tried the powder before I wrote my last post, and I was surprised to
find out it was a sunblock also. So I tried it for the first time
yesterday-and I was really impressed with how silky it felt-it didn't feel
like any powder I've used before-it was so smooth and cool feeling-almost like
it was wet- but of course isn't - and the color and consistency were fine on
my face. Will report back after I've used it for about a week. debbie g.
