I have a usual cosmetic brand which suits me fine and doesn't cause problems for my skin. Occasionally, if I try a different brand, I end up with adult breakouts on my skin. I am not sure how I can recognise why certain products do this. I recently used a different brand of cosmetic on my face (a primer) and the spots have returned! I know the answer is probably not to switch to other brands but I am curious to know what ingredients to avoid.
I just found my foundation to be pore clogging. I haven't used it in 4 days and my skin looks incredibly better. Look into a mineral line like Jane Iredale.
I usually use Oriflame and I find it to be great on my skin and light as well. But I do have a few others and tried one the other day and I now look like a teenager (sadly because of the breakout, but also have wrinkles)! I think I will stick to Oriflame as it is always fine.
I will look into this list as it is useful to have to advise others as well well looking into products.
