Fluid mineral foundations may be more beneficial for your skin than
powder ones. I have been diligently using my powder mineral foundations
for five years now, and something was always bothering me. I couldn’t
believe that inhaling those small particles of microfine powder can be
really good for me. Each time I performed that obligatory "tap, swirl
and buff” technique I could feel the powder coating inside of my nose
and scratching my throat. I am not sensitive to any chemicals and I am
not prone to allergies. So maybe inhaling mineral foundation isn’t
really good for us?
It appears I was right. In March 2008, scientists from the University
of Kyoto found that when mice inhaled titanium dioxide microparticles,
they are invaded in alveolar, transferred to organs through blood
vessels and may express biological effects were carried. After animals inhaled titanium dioxide powder, they accumulated the mineral in liver, lung, kidney,
spleen and brain. (Sakai, Matsui, Yamamoto et al. Biodistribution of
ultrafine particles of titanium dioxide by intratracheal administration
to mice. J UOEH. 2008 Mar 1;30(1):27-38.)
Earlier 2007 study found that lung cleansing cells, macrophages,
inefficiently clean nanoparticles of titanium dioxide which means that
this mineral can accumulate in lungs with unknown delayed effects.
To me, this sounds scary. I don’t want any mineral foundation in my brain. Or lungs. Do you?
Biological activity of inhaled microparticles is nothing new to
science. Spray-dried drugs are widely used to deliver medications to
lungs – it’s called pulmonary drug delivery. Nanoparticles are used to
treat tuberculosis and other lung diseases.
Nanoparticles can also kill. If you inhale small particles of talc
and silica, found in many drugstore brands of mineral foundations, you
can up your chances of getting lung cancer – not pretty at all! Silica
and talc act similarly to asbestos, although they are not as deadly, but
itâ??s not the reason to inhale them by spoonfuls.
I found that using a pressed mineral foundation, such as Jane Iredale
PurePressed mineral foundation, are less likely to form a cloud of fine
mineral dust during application. But I had a couple of jars of a really
nice mineral powder foundation – and no way was I going to bin them.
Here’s my recipe for a quick homemade firming mineral fluid foundation. Ingredients
9 g jar of mineral foundation of your choice
30 ml (1 oz) rich facial moisturizer (I use my own moisturizer for
sensitive skin from Petite Marie Organics line but rich organic body
cream works well, too. Thick, rich creams will blend easier, especially
if you add some liquid active ingredients.)
1 g green tea polyphenols (from SkinActives or other websites catering for beauty enthusiasts)
1 g Dermagen (blend of Matrixyl and hyaluronic acid)
Method:
Pour the mineral foundation into a clean wide-necked jar (beware of
inhaling the powder!). Now pour in the cream. Slowly blend with a
spatula until uniform, adding active ingredients one by one.
I expected this blend to produce quite light coverage but it appeared
to form really dense, smooth finish and blended really nicely. You can
experiment by adding a pinch of mineral aluminum-free shimmer for
additional glow.
