Hi Hurdity, ah yes, I know what you mean by milia, I had those on my face when I first became pregnant back in the day. I can't squeeze the " pips" I can feel now as they are too deep and yes they are in the fatty tissue. I'm not overly concerned and to be honest I don't know how long they have been there, I was just curious as to what they might be. Maybe they're just fatty lumps, I really do need to get back into my healthier eating plan again, I've let things slide for too long now. I could try altering my diet and seeing if that reduces them any
