| Most of us would never dream of mixing a sunscreen with moisturiser as it would obviously dilute the protection, however, if we put sunscreen on skin that is very moisturised then isn't it still reducing the effectiveness of the sunscreen as it is mixing with whatever moisturiser is on our skin? |

I use physical sunscreen with Zinc. So as long as I apply the correct amount, e.g. anywhere from 1/4- 1 tsp (roughly Ive read around) then it should be okay. Actually I have mixed my moisturiser and sunscreen too. When I don't go outdoors I figure its okay and better than nothing.
Ide say if you let the moisturiser absorb then its like any topical layering and should be okay. |

Love your username 
Well, it depends. If you are using a wholly physical sunscreen (zinc oxide and/or titanium dioxide) then you can apply it over anything..really! In terms of effectiveness, having moisturized skin will not stop the physical minerals from deflecting uv rays.
Chemical sunscreens are a little more tricky. Personally, I do not apply serums that contain occlusive ingredients, such as oils or silicons, before applying chemical SS. They need to penetrate your skin in order to work. |

I think if you are using a physical sunscreen, then just letting your moisturizer absorb well first is good enough.
Like ^^ already mentioned, it's better than nothing. Sun damage is too destructive, and it's effects are cumulative over a lifetime. You can't mess around with it.
If you are too worried about diluting it, you could DIY. But I know some people aren't comfortable with DIY sunscreen, so you could splurge on a brand you trust. Just pick a formula that has a lot of good actives in it. |

No I wouldn't use a chemical over anything either, I'm using Chanel at the moment which is actually a mix of physical and chemical but it can be very drying so I have to use a moisturiser underneath.
I got worried about protection because it didn't look as white as it does on bare skin
I'll just have to blot all my face before application to make sure there's no excess product.  |

Here's a big yes to sunumbra.
Great sunscreen. Best part? the Spf 30 is 15.6% ZNo and the Spf 40 is 19% Zno and it isn't whitening!
I emailed the owner, and two of the ingredients they use actually turn the mixture from white to an iron-oxide type colour.
So, no tints but there's no pale sheen. Definitely there's a colour but it's not noticeable. |

OP,
Can you use mineral makeup? I believe that many have an SPF?
Also, another poster said that it's not ideal to use chemical sunscreens over products, although physical sunscreens might work. Why is that? Do the chemical sunscreens interact more with ingredients than physical sunscreens? |

You can layer chemical ss over certain products as long as they do not contain occlusive ingredients such as oil or silicones. Chemical sunscreens need to be absorbed into the skin to work. So, even if your SS is part chemical, part physical, it still needs to be applied over non-occlusive products to penetrate the skin. |

I moisturize my skin first before I put my sunscreen. I don't think it will dilute the concentration as long as it is absorb in the skin. after that, I put mineral make-up on....

Yes I believe this to be true. But if you have to do it, do whatever you have to do. Like if your skin is super dry and starting to flake. I'll do this in the winter sometimes. In the summer, I try make sure that every product I use on my face has some amount of zinc oxide. Like elta- although I don't view it as a sunscreen it still has some zinc oxide so I feel ok putting it on my face, or even mixing it with burnout in the palm of my hand and then applying that. |

| Maybe alcoholic, but why not use sunscreen on its own?? That would solve the dilution problem. |
