Let's suppose a hypothetical drug causes blood vessels to grow from the dermis into the superficial stratum granulosum of the epidermis. What effect would you expect to see in the most superficial epidermal layers? Please make an educated guess based on what you have learned so far.

The epidermis would thin out because of the increased blood supply The lower layers of the epidermis would turn into dermal cells and the epidermis would thin out
