Thanks for all those great photos. MK has definitely aged worse than Ash, and I think this can be attributed to a few reasons. First of all, it seems as though she started smoking a bit sooner than Ashley (1-2 years maybe) and she almost definitely has smoked with more frequency over the years. There are tons of photos of MK chain smoking, and significantly fewer of Ash. MK also smokes Marlboros...I can't remember what kind Ash smokes (I don't know much about cigarettes), but I know the kind MK smokes has more tobacco and nicotine in it. Also, Ash has always had stronger bone structure than MK. She has higher cheekbones, a stronger brow bone, thicker eyebrows, a stronger jaw, bigger lips, and bigger eyes - she just has the kind of face that can age better. MK has softer features and smaller eyes - faces like hers don't tend to hold their structure as well as they age.
Of course, it also seems as though MK drank more than Ash when they were younger, and she certainly went through more stress (anorexia, paparazzi, the death of Heath Ledger...). Oh, and finally, MK has definitely had more work done to her face than Ash has. Ash maybe had a nose job...MK has had two nose jobs, lip injections, something done to her chin, and I think something done to her cheeks, too.
