Ingredients you should look for in a spot treatment

1. Salicylic acid- exfoliates the upper layer of the skin) and penetrates deep into pores to remove sebum. 

2. Benzoyl peroxide - kills P. acnes and Staph. Aureus bacteria that contributes to acne and helps prevent and clear clogged pores. Opt for micronized formulations; they cause less irritation to the skin and the molecules are stabilized for longer shelf life.

Also try adding a topical retinoid into your routine at least 2-3 times a week (every day if your skin is already well adjusted) to help clear gunk from pores, leaving them less swollen.
