Your question is a very good one, but to answer it, I'd have to know a little more about you.....I am a retired makeup artist and am always happy to pass on any information that can help people!!
Rather than just giving you info without knowing a little about you, I'd need to know: how old you are........taking any prescription medications?.....how long has your skin been 'dull'?..........are you recovering from any illness or surgery?
If you answer these, then we can proceed...........I bet you don't get back to me!! very few people do.......but as I said, I'm glad to help!!
