So what is the state of the art treatment for milia these days? Do they tend to go away or persist?
I've developed several (~5) milia on my face in the last few weeks, even though my skin-care regimen stayed pretty much the same. I think the only change was the inclusion of erythromycin vs teatree oil.
I'm using isotretinoin gel (0,05%) + erythromycin at night, salicylic acid or topical nicotinamide (5%) in the morning and azelaic acid (20%) in between.
Can any of these substances be the cause?
To treat already existent milia: the standard dermatological treatment is that a dermatologist prick/cut the milia open with a very small scalpel so that the fatty white mass can be gently pushed out.
Any chance of scarring with that one?
To prevent new milia: continue with a retinoid, but try tazarotene instead of tretinoin because it is the most comedolytic of all known retinoids. If you can tolerate taz every night you can even apply it twice a day because taz is photostable, unlike tretinoin.
Why do I develop milia even though I'm using a retinoid and how does isotretinoin compare to the other topical retinoids? Unfortunately isotretinoin is only popular in Europe, I think I should really switch to one of the better researched, maybe even more powerful, retinoids...
Copper peptides won´t do anything. You need retinoids (most effective) or glycolic/salicylic acids.
What's the minimum concentration required? 30%?
