Retinol: Retinol is simply another word for vitamin A, sort of like how we call vitamin B7 “biotin.” It’s important that our bodies get systemic vitamin A through our diet for good vision, a strong immune system, and general organ function, but some research suggests that vitamin A could have a positive impact on the skin when applied to it directly. The problem is, regular retinol doesn’t actually do much for acne. That’s because the retinoic acid found in retinol isn’t always activated when left to its own devices. We typically have to activate the retinoic acid synthetically through the creation of various medications.
In women, acne can be improved with the use of any combined birth control pill. These medications contain an estrogen and a progestin. They work by decreasing the production of androgen hormones by the ovaries and by decreasing the free and hence biologically active fractions of androgens, resulting in lowered skin production of sebum and consequently reduced acne severity. Although oral estrogens can decrease IGF-1 levels in some situations and this might be expected to additionally contribute to improvement in acne symptoms, combined birth control pills appear to have no effect on IGF-1 levels in fertile women. However, cyproterone acetate-containing birth control pills have been reported to decrease total and free IGF-1 levels. Combinations containing third- or fourth-generation progestins including desogestrel, dienogest, drospirenone, or norgestimate, as well as birth control pills containing cyproterone acetate or chlormadinone acetate, are preferred for women with acne due to their stronger antiandrogenic effects. Studies have shown a 40 to 70% reduction in acne lesions with combined birth control pills. A 2014 review found that antibiotics by mouth appear to be somewhat more effective than birth control pills at decreasing the number of inflammatory acne lesions at three months. However, the two therapies are approximately equal in efficacy at six months for decreasing the number of inflammatory, non-inflammatory, and total acne lesions. The authors of the analysis suggested that birth control pills may be a preferred first-line acne treatment, over oral antibiotics, in certain women due to similar efficacy at six months and a lack of associated antibiotic resistance.
We suggest avoiding spot treatments. “Benzoyl peroxide, when placed on red spots, can actually cause more irritation and inflammation to the area. It’s best used to prevent red bumps and pustules, and applied all over the area you want to treat,” said Townsend, who was also quick to naysay a spot-treat-only approach: “Acne affects all of the pores. If someone is going to spot treat against my advice, I still suggest they spot treat one day and treat the whole face the next.”
The best acne medication differs from person to person, but because acne is caused by so many different factors, the best solution for most people is an acne treatment that includes multiple key ingredients. For the vast majority of people with acne, the best medicine for acne is a gentle, over-the-counter option that treats the causes of acne without irritation the skin. Below, we’ve included three of our favorite over-the-counter acne treatment options.
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.
Tea Tree Oil – Another anti-bacterial ingredient that is common in over-the-counter treatments, tea tree oil combats acne-causing bacteria. While the FDA hasn’t officially approved it for acne treatment, some dermatologists say it’s almost as effective as benzoyl peroxide for clearing skin, although it doesn’t work quite as fast. It can be used for spot treatment as well.
Acne is the most common skin condition in the United States. Between 40 and 50 million Americans have it. It occurs at any age, but most sufferers are teenagers and young adults. Research shows four key players are involved in its formation: excess oil, clogged pores, bacteria and inflammation. The excess oil is sebum which our bodies make to prevent the skin from drying out. Sebum increases dramatically during adolescence when hormones known as androgens spur sebum production into overdrive. If excess sebum cannot flow freely to the skin’s surface, clogged pores result. P. acnes, a bacteria found on everyone’s skin, flourishes in the excess oil and results in inflammation.
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.
The dermatologist Dr. Dennis Gross did a major study on water and its effect on skin and he found that the heavy metals in tap water can actually ruin the benefits expensive lotions and serums do for skin. Some cities (New York and L.A., for example) have worse water than others (Seattle, for example). While some dermatologists aren't buying his claims, (Patricia Wexler for one), you can fight the drying effects of water on skin by cleansing with cold cream, a practice common with European women.
