Since the cause is unknown, there is not a method to prevent a dilated pore of Winer from appearing on your skin.
In order to prevent your pores from clogging, you can:
- Use skincare products that don’t clog pores (non-comedogenic).
- Use a cleanser when washing your skin to exfoliate.
- Treat acne when it occurs (use benzoyl peroxide or salicylic acid to dry out dead skin cells).
- Wear sunscreen.
