Blackheads, a type of mild acne that can develop inside hair follicles, are a common annoyance that can affect people of all ages.
Also known as “comedones,” blackheads develop when oil and skin debris collect inside a hair follicle. When the follicle is open, the combination of oil and debris can clog the follicle, creating a small blackhead that’s often visible to other people.
Although blackheads usually aren’t as severe as other forms of acne, they can be embarrassing and irritating, especially when they occur frequently or develop in large numbers.
Tretinoin, which is used to treat and prevent acne, can be useful in removing blackheads from your facial skin. Below, we’ve explained how tretinoin works and how you can use it to remove and prevent blackheads over the long term.
How Tretinoin Works to Prevent Acne
Tretinoin is a retinoid -- a derivative of vitamin A -- that increases the speed at which your body produces new skin cells. By speeding up the development of new skin cells, consistent tretinoin use can reduce the amount of oil that’s produced by your facial skin.
This makes tretinoin a useful medication for treating acne. By speeding up the development of new skin and reducing oil, tretinoin makes it less likely that oil and skin debris can collect inside hair follicles to produce whiteheads or blackheads.
In a way, you can think of tretinoin as acting almost like a fast-forward button for your facial skin cells. By helping you exfoliate and produce new skin faster, tretinoin makes it harder for old skin and oil to build up over time and cause acne to develop.
Does Tretinoin Prevent Blackheads?
While there are no studies that specifically deal with tretinoin and blackheads, several studies show that tretinoin is highly effective at treating and reducing acne.
One study from 2009 found that tretinoin had a “significantly greater” treatment success rate than a non-therapeutic placebo. In a different study, researchers noted a measurable decrease in facial acne in people given a mix of tretinoin cream and clindamycin 1% gel.
In general, while there’s no direct evidence showing that tretinoin can remove blackheads and whiteheads specifically, there are countless detailed, peer-reviewed studies that show tretinoin is highly effective at treating, removing and preventing acne.
