I have pinkish pigmentation on both of my cheeks, and a similar blemish on my right arm. In the past, I've used benzoyl peroxide and salicylic acid (both cream and face washes) but I haven't used any of them in the past 3 - 4 months. About 1 month ago, I've tried rosacea gel, and it worked for a little bit, but stopped working. For the past month (actually a little more than 3 weeks), I've only washed my face with hot water in the shower, and I apply moisturizer when I wake up and when I go to sleep. During the day, the area that has blemishes is pretty itchy and irritating. I know it's not the moisturizer irritating me because it's always like this. The blemish on my right arm used to be irritating, but I applied Triamcinolone Acetonide ointment on it to stop the itching, but the blemish is still there. Here are pictures:

Any solutions?
