Hi - have now found I can wear a chemical sunscreen if it's non-scented, and find the Peter Thomas Roth Uber Dry spf 30 to be the most suited for my skin. I want to beef up the sunscreen by using a mineral powder, the Jane Iredale Powder Me spf 30. I find the La Roche-Posay Anthelios Fluid Extreme spf 60 is the best of the mineral sunscreens, but again, would want to use powder, in this case to cut down the shine.
My question is, I believe I read somewhere - possibly in this forum but can't find it now - that some sunscreens are incompatible with each other. Especially powder, I think - you shouldn't combine it with some other ingredients.
Does anyone know anything about this?
Would much appreciate any info anyone can give.
Thanks.
