How much thicker is the dermis compared to the epidermis?

10 times thicker
15 times thicker
25 times thicker
30 times thicker

The correct answer is: 25 times thicker

The dermis is the thickest layer of skin and is approximately 25 times thicker than the epidermis. This is because the dermis is made up of dense connective tissue, while the epidermis is made up of mainly dead skin cells. Option A is incorrect as it is too low of a number. Option B is not a significant enough increase to be accurate. Option D is incorrect as it is too high and would make the dermis almost as thin as the epidermis. Option C is the closest approximation to the actual difference in thickness.
