RW, the doxy helps the texture, but only indirectly, and not 100%, in the following manner: the IPL triggered severe inflammation and a massive rosacea flare. The low dose doxy (20 mg 2 x/day, which is really a generic approximation of Oracea) is a sub-antimicrobial dose which basically kills only the inflammation. The inflammation causes acne, rosacea pustules, the swelling and edema of rosacea, etc., etc. So the doxy helps prevent bumpy texture.
Also, I never got atrophic scarring from acne or rosacea pustules before the IPL (I only got PIH and red marks, and in fact, rosacea pustules hardly EVER occurred). I now get atrophic scars from every little pustule, every little injury. It's like the collagen or whatever was damaged by the IPL and every time I get a pustule or even a scrape the skin is no longer able to repair itself like it used to, so I get a hole. So, if the doxy helps prevent bumps, it's also preventing the new atrophic scars.
So, the doxy is not able, in my opinion, to fix the immediate textural changes caused by IPL, but it helps prevent new changes caused by the IPL, and quieting down the never ending inflammatory process that IPL triggered also seems to help smooth things out somewhat. If I had to quantify, I'd say I get a 25% improvement overall in texture. I have tried stopping the doxy, and my face gets very bumpy, inflamed,more holes from the the bumps, and I end up w/ a mess.
The other aspect of IPL texture is the fact that now my face has the same look as skin that is extremely dry - lots of superficial crinkles and wrinkles all over, orange peel skin, etc. Before IPL, I had very oily, smooth skin. It is still oily, but looks shriveled and dry. I find that using a heavy cream like Cerave in a tub helps improve this texture somewhat, and only temporarily, w/ each use. I think the water attracting and holding properties of the Cerave help to temporarily plump the skin out a little and help make the holes in the "orange peel skin" appear smaller. From this, I am thinking that adding a nano-formula of a hyaluronic acid product might be even more effective, w/ the idea being that the nano particle sized formula may help the HA get down into the skin more and increase the plumping effect. Of course, HA dermal fillers injected by needle might do the same thing but much better, but I am terrified of more complications. So I am going to try to find a good nano formula HA product. I hear Hada Labo makes some.
