I haven't found a foundation that gives that dewy look AND provides a full coverage. Any ideas Buffy?
Oh, you mean the holy grail? LOL. Bourjois Healthy Mix or Jemma Kidd Light As Air would come pretty close I reckon, worth checking out. Otherwise you could try a cream or gel foundation - not cream-to-powder or gel-to-powder, one of the more traditional ones. It's a little on the expensive side, but Laura Mercier Silk Creme is gorgeous, or M.A.C Studio Sculpt. I'm still learning how to work with this one, you only need a really small amount but boy, does it cover. Like Studio Fix Fluid, it's 'satin' or natural matte but creamier.

Thanks Buffy! Satin look could still be good with an illiminnator (ummm what is am illiminnator Emma)? over the top? Can't wait to hear your reply Buffy! I also live in a hot area in QLD so sometimes 'dewy' can end up looking 'sweaty'. Maybe one of the dewy ones would be good for winter and the MAC for summer I also have skin that reacts to everything! A dermatologist has told me its seborrheic dermatitis, would the ones you've suggested be ok? I guess that's a tricky question really and a matter of trial and error... It's just an expensive process!
I know cherished, it's an expensive pain trying lots of things to find the right one! Especially if you have sensitive skin. Do you know if it's a particular ingredient that makes you react or is it a bit random? I suggest getting samples from counters or stores and taking them home to try. Good salespeople will (and should!) do this for you. It also means you can see the foundation in different lights, rather than those hideous fluro ones in stores. Always, always check your foundation in natural light before you buy it. Don't buy on the spot! Boy, have I learnt that the hard way over the years. FYI I've never had any clients that have had issues with M.A.C foundations but you never know, so definitely go the sample route if you can.

Illuminators are lovely - am sure Emma will explain why she likes the one she uses. My only tip there would be to choose something shimmery, not glittery.

Sorry Netix! Let me know if you have any more questions. Am sure others will post some ideas in here too.
