I am a fully trained makeup artist, specialising in camouflage makeup and false eyelash application for chemotherapy.
Suffering from rosacea myself, i initially found it impossible to strike the balance of coverage and smooth texture. My rosacea is in the 'butterfly' style (sounds cute at least!) and - so far - without texture,thread veins or spots.
I find using a green toned moisturiser (hypoallergenic!) as a base works really well first of all. If anyone would like names of brands I can happily recommend. Follow this with a mineral foundation using a big kabuki brush (fluffy but flat on top) and keep buffing away. Mineral powders are generally just crushed pearl that's baked into a solid round. The mineral aspect means a. They won't clog your pores (you could even sleep in it, although I wouldn't recommend it! Cleansing is key with his condition) and b. Even though they are powder, if you keep buffing in circular motions it can break down the 'powdery' effect to give you lovely fresh glowy skin and just the right amount of coverage. Skin should look like skin! This technique works great on acne too.
I'm new to this forum so I don't want to name brands in case that's not allowed, but let me know if anyone would like more advice. I've worked with tons of conditions and disfigurements, and love to help give advice wherever possible. Please note that I am self employed and do not endorse any brands! Just here to help
