Me: I can only really tell you how to cover up and soothe rosacea. Only dermatologist prescribed treatment can cure or control it.
As for acne scarring, you might want to try Stri-Vectin. It's pretty pricey ($135), but it lasts a long time and works wonders. Within 2 weeks of using stri-vectin, my purple stretch marks turned white. Stretch marks are scars too. For something less expensive, start out with Maderma (you can get it at Walgreens, $30) until you notice results are not improving anymore, then move up to stri-vectin. You will need to use a very good moisturizer on top of Maderma and Stri-Vectin, because there is a lot of retinol in it and will make your skin feel dry and uncomfortable.
When you cover up acne scars, always wear a makeup primer underneath your foundation. This will fill in any lines, wrinkles, pores and acne scars so that your skin will have an even texture. Since you have a lot of redness, I suggest using the Sephora brand green corrector primer ($15). The green hue will neutralize any redness. Follow with your foundation, and setting powder.
Jane Doe: Ok I will do when I can find one in my area and TY for the advice. Doctors are way to expensive for me right now to go to for skin care. I used to have a face wash with tea tree oil in it that worked wonders for the Rosacea but it is no longer made I have looked for a new one to try but can't find anything like it. Never thought of using Maderma on my face I have some and will be using it thank you.
Me: If you can find pure tea tree essential oil, one drop in your cleanser and/or moisturizer should do the trick.
