I have rosacea and I get tiny hard kernel feeling bumps on my face that look like pimples but don't act like them. The derm doc gave me prescriptions for metronidazole and can't think of the other but neither helped. What helps a lot is azelaic acid which I figured out many years ago by doing my own research. I first found it on an international pharmacy for $20 and the same was $300 in the US, crazy right? I did confirm this with a dermatologist I saw who is from India. The Ordinary brand Azaleic Acid 10% makes a very nice one that is sold at Sephora $7.90 - super soft cream, you'll find others by googling. I have one called Finecea also. Azelaic acid works if it is rosacea. I recently found a serum azelaic acid that I like a lot that I found on Amazon, a serum, which does not feel as if it adds another layer to my face. I often just dab it on a spot when I get one. The serum has a dropper and when I was at the last 1/4-1/3 of the bottle, I added water and dropped it into the itchiest spots I get on my scalp where I got no relief with anything I tried. It worked miraculously. Lastly, I recently began using the top line department store skin care products by La Mer and I couldn't believe how it cleared my skin overnight, practically. It was an obviously improvement overnight. La Mer products worked the best but cost the most. Obviously, none of these options I mention are covered by insurance but the physicians ideas don't work. Not for my rosacea. I have an occasional keratosis crusty thing that shows up but it is different, it feels more like a superficial crusty stand-alone tag. My husband who never wore sunscreen has them all over his back. The skin I have is so incredibly reactive I guess and I study the internet for similar symptoms then try everything. Sadly, the docs can't fix everything and don't always have the time for the details.
