That is because these marks are not actually blackheads at all, according to TheDailyDerm YouTube channel, which is run by dermatologists in partnership with skincare brand CeraVe.
These spots are known as sebaceous filaments, which are thin, hair-like structures that help move natural oils, also called sebum, from inside the pore to the surface of the skin.

Because of this key difference, they require a different approach when it comes to treatment and removal.
The expert said that a chemical exfoliant, such as salicylic acid, can break down oil and dead skin inside the pore and clean it more thoroughly. Another option is to visit a dermatologist, who can use specialized tools to safely empty the pores by hand.
She said: “It’s important to note that this is a normal function of the skin. Pores aren’t blocked or clogged in the same way as when you have a blackhead. Sebaceous filaments do vary in colour and may appear as a grey, light brown or yellow ‘spot’.”
