A major mechanism of acne-related skin inflammation is mediated by P. acnes's ability to bind and activate a class of immune system receptors known as toll-like receptors (TLRs), especially TLR2 and TLR4. Activation of TLR2 and TLR4 by P. acnes leads to increased secretion of IL-1α, IL-8, and TNF-α. Release of these inflammatory signals attracts various immune cells to the hair follicle including neutrophils, macrophages, and Th1 cells. IL-1α stimulates increased skin cell activity and reproduction, which in turn fuels comedo development. Furthermore, sebaceous gland cells produce more antimicrobial peptides, such as HBD1 and HBD2, in response to binding of TLR2 and TLR4.
Although combined oral contraceptives are a more popular treatment with women, men can use them as well, as they may also experience hormonal fluctuations. The only downside is that birth control pills tend to produce feminizing features in the person taking them, such as reduced hair growth or enlarged breast tissue. To get a prescription for a combined oral contraceptive, you can talk to your family doctor, a dermatologist, or an OB/GYN, or visit your local Planned Parenthood.
Dapsone is a topical gel medicine sold under the brand name Aczone for treating severe acne, and it’s perfect for people who want a low-maintenance acne treatment plan. Unlike many of the best acne medications, dapsone only needs to be applied once daily, and it is the only medications most people will need, though it’s always good to include a face wash and moisturizer in your skin care routine if possible. Dapsone can function on its own because it is both antibacterial and anti-inflammatory10, effectively taking care of two of the biggest causes of acne.
Just as its name suggests, this oil-free cleanser comes out in suds, making it one of the most frothy-fun face-washing experiences you'll ever have over the bathroom sink. (Just try not to blow those bubbles, we dare you.) But the bubbly formula isn't all froth and games—it's also spiked with salicylic acid to target (and prevent) breakouts and aloe to soothe underlying redness.
For mild to moderate acne, dermatologists often suggest an acne face wash with bacteria-killing benzoyl peroxide (to minimize irritation, 3.5 percent strength should be your max if you have sensitive skin), along with a prescription topical antimicrobial such as clindamycin or erythromycin. If you rather go with a gentle face wash for sensitive skin, you can use that and apply a benzoyl peroxide acne spot treatment instead.
According to Dr. Bailey, the best facial cleansers for acne should have at least one of these key ingredients: salicylic acid, glycolic acid or benzoyl peroxide. Cleansers with these ingredients can penetrate your pores and eliminate pore-clogging impurities—like dead skin cells, makeup, excess oil and bacteria—that irritate skin and make acne worse.
Any acne treatment is a weeks-long experiment that you’re conducting with your skin. Acne is slow to heal, and in some cases, it can get worse before it gets better (nearly every benzoyl peroxide product we looked at emphasized the likeliness of irritating acne further, and starting off with a lighter application). April W. Armstrong, a doctor at the University of California Davis Health System, recommends waiting at least one month before you deem a product ineffective.
Diet. Studies indicate that certain dietary factors, including skim milk and carbohydrate-rich foods — such as bread, bagels and chips — may worsen acne. Chocolate has long been suspected of making acne worse. A small study of 14 men with acne showed that eating chocolate was related to a worsening of symptoms. Further study is needed to examine why this happens and whether people with acne would benefit from following specific dietary restrictions.
Pharaohs are recorded as having had acne, which may be the earliest known reference to the disease. Since at least the reign of Cleopatra (69–30 BC), the application of sulfur to the skin has been recognized as a useful treatment for acne. The sixth-century Greek physician Aëtius of Amida is credited with coining the term "ionthos" (ίονθωξ,) or "acnae", which is believed to have been a reference to facial skin lesions that occur during "the 'acme' of life" (puberty).
What's Going On: You might be all too familiar with these, which tend to make their debut when you’re in high school. "Blackheads, like whiteheads, are blocked pores," says Zeichner. What gives them their namesake color, though, is the oil. It's already dark, but blackheads also have a larger opening at the surface than whiteheads do, meaning air can enter and oxidize that oil sitting inside the pore, turning it even darker.
No single product can contain all of the necessary acne-fighting ingredients, despite what some may claim. Some chemicals shouldn’t be used together, while others work together to totally eradicate acne and all the blemishes that come with it. The best acne treatment systems can do that for you, but because everyone’s skin is unique, what works for one person may not work for another. The key lies in finding the right system, a combination of products, that work best for your unique skin.
“Acne cleansers with these ingredients will gradually unclog pores, reduce the size of existing blackheads and slow or stop the formation of new ones,” she says. “Benzoyl peroxide is also the best ingredient for treating the acne-causing bacteria called p. acnes. In fact, study after study continues to show that benzoyl peroxide is more effective than prescription topical antibiotics at treating p. acnes.”
