Too much of facial treatment is bad

Is it true that too much of facial treatment actually thin the skin? If this is true, then this might explain why the sight of green veins on my face is becoming more and more obvious.

I remember my beautician told me that regular facial treatment cleansed the face off impuritants and make it clear. Hence, marks/stains or in my case the veins which were not clearly visible earlier will begin to be more obvious.

I don't mind if the above is true. Or else something may be very wrong if there is green stuff growing on my face!
