But my foundation still doesn't cover up redness for a long enough time...without primer, it last about an hour until the redness peak through. What foundations do you recommend? I have oily to combo skin, sensitive also.
Use an oil-free primer as per usual, Smashbox's Photo finish has an oil-free version.
I recommend creme based foundations like Kryolan, Eve Pearl, Cinema Secrets, Dermablend, Dermacolor, Joe Blasco, Graftobian, Mehron, RCMA. You will definitely find a shade here and the price points are in the same ballpark.
Kryolan's Dermacolor line, Joe Blasco, and RCMA have medical grade foundations for skins healing from laser, chemical therapies, burns, grafts etc. The other brands are very comparable like Eve Pearl and Cinema Secrets.
Work from a palette. Metal, ceramic, glass, whatever, just not plastic! That way you can sheer out the texture if you find it too thick, most likely you won't as these brands' foundations are very workable. Also you'll save product working from a palette.
I recommend using a proper foundation brush for application, and NOT a fibre optic brush. (Again, you're working with cremes, not liquids!). Because of your skin's sensitivity, stipple your foundation on. Also, it's the correct way anyway... And no redness should be peaking through.
Liquid foundations are too sheer, hence they don't have the 'physical blocking' (texture) of a creme formulation to effectively cover extreme redness.
Use an oil-free powder with a washable velour puff, not a powder brush! Always pat and press the powder on with the puff to set the foundation.
Touching up throughout the day is normal. Based on your info, I suggest using blot papers first. MAC Blot Film is excellent, and then reapply with an oil-free blot powder using a puff.
I know you've heard it a thousand times... Avoid touching your face. I know it's difficult, but try too.
If any redness starts to peek through in the late afternoon, Just reapply with your foundation brush and then powder. Since this is just you, put a small amount of foundation on the inside lid of the palette and work from there.
However at this point in the day, it's probably Miller Time anyway, and it's time to punch-the-clock. In which case you can just go home and wash the day off, or if you have other plans, you can either wash and redo, or just touch up and go.
