I'm currently in my second month of roaccutane. I couldn't live without concealer, however I never use liquid because in my opinion it's just foundation labelled as concealer. I am a big fan of Studio Finish concealer by MAC and Secret Camouflage concealer by Laura Mercier. Both have to be applied with a brush so maybe buy a cheap one to try the concealers with before you invest in a good one! The Laura Mercier concealer is obviously slightly more pricey but to be honest, I think MAC is just as good, if not better.

No one believes I even have acne when I go out and I think it's down to these concealers

But then again I'm not in the REALLY dry stages of the tane yet.. so I hope these carry on working for me because they work wonders now. When I do have dry patches I tend to just apply as normal and then apply liquid foundation over.

I finished my Accutane and during the time I was on it I did have dry patches. I purchased the hydrating mist from Sephora or Amazon and I would spray my face throughout the day. It did not mess up my makeup and I sprayed a lot on before bed. It helped very much and soothed my skin. Accutane was the best thing I have ever done. I love my skin.

use a silicone based primer like W7 primer (from amazon) or smashbox primer on top of heavily moisturised skin.

Then good foundations for dry flakey skin are Rimmel match perfection, Chanel Vitalumiere Aqua, bourjuois healthy mix.

After foundation spray with a hydrating spray (glycerin + rose water) and then powder with silica powder (elf or MakeupForever HD powder).

Neutrogena Healthy Skin helped me, followed after Cerave MOisturizer.

Right, on my second round, I just use Dior Nude.

If you're still prone to breakouts I would suggest staying away from Neutrogena healthy skin as it contains ethylhexyl palmitate as one of the main ingredients...
