Blackheads form when pores fill with debris but stays open. According to dermatologist Rachel Nazarian, “blackheads are just an oxidized mix of oil and dead skin cells that are sitting in pores — the exposure to air is what causes them to oxidize and turn black. Having them is not a sign that you're too dirty, so don't cause more damage by being rough with your skin and scrubbing really hard."
What to do:
Salicylic acid is a great option for blackheads. This ingredient works best in a leave on product like a toner, gel, or lotion. When found in cleansers, it just isn't left on the skin long enough to be effective. It helps unclog your pores and the best way to use it is by using it 1 to 2 times a day, in concentrations between .5 and 2%
Exfoliate twice a week.
Baking soda helps to neutralize pH imbalances and exfoliates to remove dirt, oil, and dead skin cells. To use this on your blackheads, apply a mix of baking soda and water and apply on your face. After 5 minutes, rinse off with warm water and moisturize.
Apply tea tree oil directly to the affected areas to help blackheads on your chin and nose. Tea tree oil works in part by killing bacteria naturally. Tea tree oil works because it disinfects. Soothes, and contains antibacterial properties.
What else should I know?
Salicylic acid is a better blackhead remedy than benzoyl peroxide because it helps exfoliate and unclog your pores whereas benzoyl peroxide kills acne bacteria.
