[Acne] Got my first ever (supposedly) blind pimple. What do I do?

Pimple under iPhone flash lighting.

Hey, everyone. This is my first post here so I hope I'm doing this right. :)

I [M15] got this red spot yesterday and I don't know if it's cystic acne or a clogged pore.

I have combination-sensitive skin.

My normal routine includes the CosRX Daily Salicylic Acid Cleanser on wet skin, and then the CeraVe Hydrating Cleanser after to make up for the dryness after exfoliation. I then moisturize with Lubriderm body cream.

It's my usual routine and I have NEVER faced issues with it.

Two days ago, though, I decided to use the Centella 2004 Oil Cleanser to attempt to pull out a sebaceous filament that I mistook as a blackhead. The red spot in the picture showed up yesterday morning when I woke up since I used the oil cleanser the night before, and I am assuming it is why I broke out.

I used this a few months back in 2024 too and had the worst breakout of my life and got a bunch of dark spots that took weeks to fade but never something like this, and I made a mistake and ended up using the oil cleanser again in desperation.

I don't want to risk anything while I'm still young and my skin is still able to bounce back from a lot of stuff, so I'm coming to see what to do from here.

I'm afraid it'll take a year to disappear because it's HUGE and I don't have a lot of skincare items at my disposal. Hoping to bring to a head or make it disappear in at least a month.

What should I do?
