What it does: Benzoyl peroxide is the only known substance which can bring oxygen under the skin surface. Since bacteria cannot survive in the presence of oxygen, when used in an adequate dosage, benzoyl peroxide eradicates 99.9% of these bacteria almost immediately. It also exerts a mild drying and peeling effect, which is thought to help prevent breakouts.1-6 Benzoyl peroxide also helps lessen inflammation.7-9 2.5% benzoyl peroxide is just as effective as higher concentrations with less side effects.6,10
The costs and social impact of acne are substantial. In the United States, acne vulgaris is responsible for more than 5 million doctor visits and costs over US$2.5 billion each year in direct costs. Similarly, acne vulgaris is responsible for 3.5 million doctor visits each year in the United Kingdom. Sales for the top ten leading acne treatment brands in the US in 2015, have been reported as amounting to $352 million.
To properly use sunscreen, you should put it on about 30 minutes before you plan to go outside. You will also need to reapply it if you sweat a lot. Be generous when you put it on and consider looking for a lip balm sunscreen specially made to protect your lips. Finally, make sure you are drinking enough fluid, so you don’t dehydrate your skin while outside.
Dermatologists aren’t sure why azelaic acid is so effective at clearing up inflammation, but it’s often used as an option for sensitive skin or pregnant patients. Linkner says the ingredient is good at treating malasma, acne, and rosacea. Your dermatologist can prescribe a foam product with azelaic acid, and you can also find beauty products with very small amounts of this active ingredient.
P. acnes also provokes skin inflammation by altering the fatty composition of oily sebum. Oxidation of the lipid squalene by P. acnes is of particular importance. Squalene oxidation activates NF-κB (a protein complex) and consequently increases IL-1α levels. Additionally, squalene oxidation leads to increased activity of the 5-lipoxygenase enzyme responsible for conversion of arachidonic acid to leukotriene B4 (LTB4). LTB4 promotes skin inflammation by acting on the peroxisome proliferator-activated receptor alpha (PPARα) protein. PPARα increases activity of activator protein 1 (AP-1) and NF-κB, thereby leading to the recruitment of inflammatory T cells. The inflammatory properties of P. acnes can be further explained by the bacterium's ability to convert sebum triglycerides to pro-inflammatory free fatty acids via secretion of the enzyme lipase. These free fatty acids spur production of cathelicidin, HBD1, and HBD2, thus leading to further inflammation.
Accutane (isotretinoin) has a mixed reputation, but among dermatologists it’s the finisher for patients with severe acne. “If you have an acne patient that doesn’t respond to anything, [Accutane] can really be a game changer,” board-certified dermatologist Adam Friedman tells SELF. Accutane is an oral retinoid, and it has all the same benefits of a topical retinol but is even more effective.
The use of antimicrobial peptides against P. acnes is under investigation as a treatment for acne to overcoming antibiotic resistance. In 2007, the first genome sequencing of a P. acnes bacteriophage (PA6) was reported. The authors proposed applying this research toward development of bacteriophage therapy as an acne treatment in order to overcome the problems associated with long-term antibiotic therapy such as bacterial resistance. Oral and topical probiotics are also being evaluated as treatments for acne. Probiotics have been hypothesized to have therapeutic effects for those affected by acne due to their ability to decrease skin inflammation and improve skin moisture by increasing the skin's ceramide content. As of 2014, studies examining the effects of probiotics on acne in humans were limited.
If you're willing to invest in some serious skincare to soothe your acne-prone skin woes, Lancer's blemish-control polish is a great addition to your skincare routine. This treatment can be used as an exfoliant in conjunction with the best spot treatment for your acne type to further treat severe acne and improve the overall appearance of blemishes.
The alkaline ingredients in Ivory Soap reach into the skin and dissolve the fats and ceramides that lock moisture in and keep the skin soft and flexible. Tight skin constricts pores, locking oil and acne bacteria inside. If you wash your face with Ivory Soap once or twice a day, you almost certainly will have no big pieces of dirt or grime lurking in enlarged pores, but you are likely to have an ongoing problem with whiteheads and blackheads, and the constant irritation will also make pimples redder and more inflamed.
