Does cleansing oil clog pores or help with blackheads?

An oil cleanser can help remove makeup, sunscreen, and surface oil. If congestion is the concern, I would still assess the type of bumps rather than treating oil cleansing itself as the extraction step.

Oil cleansing is not automatically pore-clogging

The formula, massage time, emulsification, rinsing, and your own response matter more than the word “oil.”

Black dots are not always blackheads

Some visible nose dots are sebaceous filaments, which are normal structures that refill. Repeated squeezing or long massage sessions can create irritation without permanently removing them.
