Hello Chris,
 
I have just looked at the section 'How does  suncream work?'.

Can you tell me, if you apply suncream and then cover it  with make-up (on your face), will the suncream still work, or does the make-up  stop the suncream from absorbing or reflecting the UV light?
 
I love the website, great experiments!
 
Kind regards,

What do you think?

I would have thought that unless you manage to remove the suncream underneath then the makeup can only make it better as it will be getting between you and the sun and must be reflecting some light in order to change the colour of your face.

Many base make-ups contain sunscreen themselves these days, although I understand that it is not reccomended to rely solely on this for protection.

I think you will find the recommendation is to use a moisturiser with a fairly high SPF before applying the make-up.

But what do I know??? I'm a geezer!

In case, you should worry that make-up compounds wouldn't have a photo-chemical reaction with suncream generating toxic compounds.

Given the extent of testing on cosmetics, I doubt that would be the case.

But then, we all make mistakes.

I would say that if you want to use sunscreen just buy a foundation (makeup) that alread contains SPF.  Otherwise, if you still want to apply sunscreen and a foundation, I could suggest applying first the sunscreen and waiting for it to settle on the skin before applying the foundation. I don't think both should be applied at the same time as I imagine it might look too greasy or will create a thick coat in the skin.

I find a moisturizer with sunscreen helps a great deal as does as Don Said, Geezer or not, that most makeup has the uv protection built into it these days...

 You must also consider there are some people who have allergies to the sunscreen therefore you need to test it prior to using it as you should with any product you apply to ones skin!.

I do wonder how much no UVB protection in makeup would effect the skin because it would seem odd to put sun screen over makeup.. under perhaps I use a spray on sunscreen that does not leave that really greasy look if I am not wearing and other protective lotions such as uvb moisturizers or makeup!
