Why you shouldn't use foundation often:
It clogs pores, which leads to problems with the work of the sebaceous glands.
It provokes the appearance of mimic wrinkles.
May cause allergic reactions, rashes, acne.
These are the main problems that arise in the process of using foundation. Another disadvantage is that the skin of the face ceases to receive the necessary amount of oxygen.

It is not necessary to use the tool often. The best option would be to use foundation every three days.
