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.”
If you're looking for suggestions on how to get rid of acne overnight, using toothpaste for acne spot treatment has probably come up. But does it work? Toothpaste contains ingredients like baking soda, alcohol, hydrogen peroxide and menthol that can dry out acne. However, some experts warn that using toothpaste for acne can actually cause over-drying and even skin peeling, so it should be used with caution. Here's how:
Post-inflammatory hyperpigmentation is not an acne scar, but a red, pink, brown or tan skin discoloration where acne has previously flared up. It'll usually disappear on its own in a year or so. Many skin lightening products claim to help reduce the visibility of these acne "scars." Their active ingredient, hydroquinone, works to slow melanin production and can reduce dark brown marks, but melanin isn't the cause of red and pink acne discolorations. A better option is to use the best foundation for acne prone skin you can find to hide the marks until they naturally fade away.
Combined oral contraceptives. Four combined oral contraceptives are approved by the FDA for acne therapy in women who also wish to use them for contraception. They are products that combine estrogen and progestin (Ortho Tri-Cyclen, Yaz, others). You may not see the benefit of this treatment for a few months, so using other acne medications with it the first few weeks may help.
Antibiotics. These work by killing excess skin bacteria and reducing redness. For the first few months of treatment, you may use both a retinoid and an antibiotic, with the antibiotic applied in the morning and the retinoid in the evening. The antibiotics are often combined with benzoyl peroxide to reduce the likelihood of developing antibiotic resistance. Examples include clindamycin with benzoyl peroxide (Benzaclin, Duac, Acanya) and erythromycin with benzoyl peroxide (Benzamycin). Topical antibiotics alone aren't recommended.
